On Knowledge Creation and Learning at the Intersection of Product Development and Engineering Education
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Today’s demands on higher engineering education given the rapid transformation of society are, to say the least, multifaceted. Rapidly increased complexity of technology as well as adaptation to sustainability requirements are causing major transformations and mergers of whole domains of technology that strongly impact current and future engineering workforces within these domains, in particular, the need for new competencies. To adapt to industry demands for engineering competence that fits new constellations of technology domains, providers of advanced engineering training – i.e., engineering faculties – need to inventory their toolbox for ways to support knowledge creation processes. Product development theory is a central part of many types of academic engineering programs. However, as the product development process itself is a process of knowledge creation, it also has strong relations to theories of learning. This thesis explores the idea that some of the tools of engineering that are also taught at engineering faculties and therefore are familiar to their members can beneficially be applied to the development and management of engineering curricula. This thesis explores the domains of product development theory, engineering education and learning analytics in search of overlapping approaches to knowledge creation. The outcome of this search, which are also the result of this thesis, is a set of proposed tools, measures, and approaches for the development, management, content, and arrangement of engineering curriculum. The main contributions focus on the use of physical artifacts and their contribution to engineering educational frameworks, such as the Conceiving – Designing – Implementing – Operating (CDIO) initiative. For this purpose, the thesis picks up on a previously developed concept of low-cost demonstrators for the establishment of a formalized learning and enabling platform that promotes implementation and execution of the CDIO framework. Furthermore, by adopting a similar approach to product development and learning theory, additional tools are identified and developed for curriculum adaptation, enhancement, and management. In particular, by examining the curriculum from previously unexplored perspectives followed by establishment of novel measurements, this thesis demonstrates how curriculum developers and program managers can increase their insights into the outcomes of their decisions.

Introducing New Materials in the Automotive Industry : Managing the Complexity of Introducing New Materials in Existing Production Systems
- 2017
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Passenger vehicles are central to Western society, and contribute to a significant part of our greenhouse gas emissions. In order to reduce emissions, the automotive industry as a whole is working to reduce mass in passenger vehicles in order to reduce energy consumption. One way to reduce mass is to introduce lightweight materials in the body of the vehicle. This research aims to explore the relationship between product and production system when introducing new materials.Besides a theoretical review and an industry-centered technological mapping, four case studies have been conducted during the course of this licentiate thesis. Two case studies were conducted with engineering design students working as development teams, one case study with the author as the developer and finally one case study in an industrial environment at a product owning company with in-house production. The goal of the case studies has been to increase the collective knowledge of how product development decisions affect production development decisions, and vice versa, when developing passenger vehicles in new materials.In the following analysis of case study outcomes, a number of factors important for introducing new materials are discussed. The relationship between product and production is investigated, both in terms of how the production system affects the product and how the product affects the production system. The outcome from this analysis is a mapping of important factors for automotive industry companies to understand and identify when looking at introducing new materials in existing production systems. Finally, a suggestion for future research efforts is presented.

- As manufacturing industry seeks different strategies and technologies to respond to the ever-increasing demands in markets that prioritize versatility of products with low-volume productions, certain technologies and strategies gain more attraction and form higher acceptance levels among different sectors. Individual firms are driven by their market requirements. Various factors including product specification, assembly sequence, and manufacturing operations are central to the decisions that are made with respect to the type of technology to respond to market dynamics. Additive Manufacturing (AM) is one of the technology alternatives that has exhibited remarkable strengths in countering market disruptions. Although AM can be utilized along conventional technologies (i.e., subtracting and forming) in a hybrid context to combine advantages and offset weaknesses of each category, the arguments supporting its applications would need to be formulated rigorously to ensure investments are rightfully justified. Another alternative continuously investigated by companies is automation and more specifically, using robotics for various purposes e.g., operations like welding and painting, material handling, machine tending, etc. Both industrial robots and the applications that require a collaboration between humans and robots can be valid in this context. Considering advancements in AM and Automation and their potentials in increasing flexibility, expediting operations, and leveraging cost advantages, this paper explores how AM and automation in tandem could improve flexibility in productions. Results of this study can be used for proposing a conceptual model which will be further developed and then tested on industrial cases in future studies. While this study incorporates raw data about processing requirements in production that has been obtained via interviews with industrial companies, inputs about the technologies i.e., AM and robotics are derived from literature.

Konferensbidrag (refereegranskat)abstract
- Identification of flawed assemblies and defective parts or products as early as possible is a daily struggle for manufacturing companies. With the ever-increasing complexity of assembly operations and manufacturing processes alongside the need for shorter cycle times and higher flexibility of productions, companies cannot afford to check for quality issues only at the end of the line. In-line quality inspection needs to be considered as a vital part of the process. This paper explores use of a real-time automated solution for detection of assembly defects through YOLOv8 (You Only Look Once) deep learning algorithm which is a class of convolutional neural networks (CNN). The use cases of the algorithm can be extended into detection of multiple objects within a single image to account for not only defects and missing parts in an assembly operation, but also quality assurance of the process both in manual and automatic cells. An analysis of YOLOv8 algorithm over an industrial case study for object detection shows the mean average precision (mAP) of the model on the test dataset and consequently its overall performance is extremely high. An implementation of this model would facilitate in-line quality inspection and streamline quality control tasks in complex assembly operations.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The use of automation is reshaping tasks in diverse industries, leading to increased productivity and efficiency. The manufacturing sector, in particular, has enjoyed significant advantages from automation, including enhanced quality control, waste reduction, and improved worker safety. However, while the advantages of automation in manufacturing are clear, the implementation of automation in complex manufacturing processes is not without its challenges. One such challenge is ensuring adaptability to new products. In addition, the initial investment for automation in manufacturing processes often presents a significant financial difficulty, particularly in the areas of engineering, design, and programming. The aim of this paper is to provide flexible solutions that can be adopted on any manufacturing line within a short timeframe. This type of flexible solution is referred to as Automation Packaged Solution (APS). APSs involve the deployment of robotic systems and vision technologies to automate specific tasks. The key advantage of these flexible solutions is their ability to adapt to the introduction of new products into the production line without the need for extensive reengineering and reprogramming. The approach involves designing detailed computer simulations based on the initial solutions and bringing the solution to life through an offline commissioning method. In this research, a case study was conducted at a manufacturing plant in Sweden, where two APSs were introduced to their assembly line: Precise screwing and accurate application of product labeling. These APSs play a crucial role in facilitating rapid upgrades and adjustments to automation systems, especially considering the diverse range of product models. This adaptability reduces the time and resources required for reconfiguration and contributes to enhanced operational efficiency, cost-effectiveness, and more sustainable manufacturing solutions. Moreover, it opens up the possibility of transferring these APSs to another production line if the need arises.

Tidskriftsartikel (refereegranskat)abstract
- With increasing use of fiber reinforced polymer composites follows a natural pursuit for more rational and effective manufacturing. Robotic pick-and-place systems can be used to automate handling of a multitude of materials used in the manufacturing of composite parts. There are systems developed for automated layup of prepreg, dry fibers and thermoplastic blanks as well as to handle auxiliary materials used in manufacturing. The aim of this paper is to highlight the challenges associated with automated handling of these materials and to analyze the main design principles that have been employed for pick-and-place systems in terms of handling strategy, reconfigurability, gripping technology and distribution of gripping points etc. The review shows that it is hard to find generic solutions for automated material handling due to the great variety in material properties. Few cases of industrial applications in full-scale manufacturing could be identified.

-
Ingår i: ICCM International Conferences on Composite Materials. - : International Committee on Composite Materials.
-
Konferensbidrag (refereegranskat)abstract
- With an increased use of composite materials follows a need for rational, cost-efficient manufacturing processes. This paper explores how off-the-shelf solutions, developed for other purposes than composite manufacturing, can be used to build systems for automated composite manufacturing. Three demonstrators, each of them dealing with a specific type of material and all of them representing different manufacturing technologies for automated composite manufacturing, are presented and analyzed to find aspects that affect the ability to use off-the-shelf solutions. The three demonstrators target low to medium manufacturing volumes of complex products and they have been developed in collaboration with industrial partners within the aerospace industry. The conclusions drawn from the development of the demonstrators are that it is technically feasible to use off-the-shelf solutions in the three cases while adhering to the high quality standards of the industry. Furthermore three groups of aspects, quality aspects, product aspects and system aspects, which affect the ability to use off-the-shelf solutions for automated composite manufacturing, are identified.

Robot-forming of prepreg stacks - Development of equipment and methods
- 2016
-
Ingår i: ECCM 2016 - Proceeding of the 17th European Conference on Composite Materials. - : European Conference on Composite Materials, ECCM. - 9783000533877
-
Konferensbidrag (refereegranskat)abstract
- Within the aerospace industry the manufacturing of composite components with complex shapes, such as spars, ribs and beams are often manufactured using manual layup and forming of prepreg material. Automated processes for prepreg layup and efficient forming techniques like vacuum forming are sometimes difficult to employ to these type of products due to technical limitations. This paper describes the development of tools and the forming sequence needed to automate sequential forming of a complex shape using an industrial robot. Plane prepreg stacks are formed to the final shape using a dual-arm industrial robot equipped with rolling tools. Tests show that the developed tools and the employed sequence can be used to form stacks to the desired shape with acceptable quality.

REMAnufactuRing – Key enABLEr to future business (REMARKABLE)
- 2023
-
Konferensbidrag (refereegranskat)abstract
- Circularity through remanufacturingRemanufacturing can be described as a process of bringing used products to “like-new” functional state. It is an industrial process whereby products referred as cores are restored to useful life. During this process the core pass through a number of remanufacturing steps, e.g., inspection, disassembly, part replacement/refurbishment, cleaning, reassembly, and testing to ensure it meets the desired product standards’.Remanufacturing involves not only new processes but also necessitates changes in product design, the adoption of new business models, advancements in information management, and the inclusion of sustainability assessments. These assessments ensure that the new designs and circular business models implemented are not only circular but also sustainable. All these aspects form a crucial part of the REMARKABLE project, contributing to the development of a comprehensive remanufacturing ecosystem.The purpose of the REMARKABLE project is to support manufacturers to become more resilient, circular, and sustainable through remanufacturing and contribute to a more efficient use ofresources.Project activities and initial resultsThe REMARKABLE project involves six highly engaged manufacturing companies from a variety of sectors that will collaborate during 2022-2025. At first, workshops have taken place with each company to identify needs, challenges and ambitions. In addition, five student projects have been conducted during spring 2022 along with two study visits at participating companies.Initial company discussions shows that remanufacturing tends to question current business models and generate grounds for circular business models development (e.g. leasing, rental, deposit system). Remanufacturing often also questions the current value network and the actors in it, as remanufacturing flows can generate need of new business relationships whilst maintaining current business models.Remanufacturing poses challenges due to small batch sizes, low automation, and reliance on manual labor. Flexibility and specific capabilities are needed to handle uncertainties, complexity in planning, and ensure efficiency. Tools, methods, and frameworks are necessary to effectively balance all three pillars of sustainability. The development process of remanufacturing systems plays a critical role in achieving sustainability performance which also requires effective information management.Commonly, the products are not adapted for remanufacturing. Within the REMARKABLE project we are investigating how to make the products easier to remanufacture by design. This includes for example aspects of making the product easier to clean and disassemble.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Metal cutting industry, a key sector in manufacturing, is grappling with the transition to a "net-zero industry" to mitigate climate change and reach sustainable practices. Rare and exclusive materials make recycling and reusing cutting tools more pressing and necessitate efficient circular material flows. The purpose of this research is to explore how collaboration can facilitate circularity in the cutting tool industry. It examines the involvement of stakeholders and their roles in achieving a circular lifecycle for cutting tools. To investigate the interaction between metal cutting tools suppliers and Small and Medium-sized Enterprises (SMEs), this study used a mixed-methods approach that includes data from literature, interviews, and document study. Empirical data is gathered to investigate the factors driving circularity and to identify important participants in the lifecycle of cutting tools. The study revealed challenges to the current situation including underutilization of tools due to the absence of a standardization process and subjective operator judgment, as well as lack of traceability of the tools both internally at SMEs and between the stakeholders. Moreover, by mapping the current actors, the study found cutting tool traceability, undirected decision-making throughout tool lifecycles, and limited awareness of circularity dimensions are key challenges. To handle these challenges. 9Rs circular economy framework used to investigate the possible role of collaboration emerges as a vital enabler for circularity, with SMEs playing a significant role. Moreover, the involvement of machine operators, often overlooked actors, is found to be crucial in influencing circular outcomes. Digital solutions and collaborative strategies that involve CNC machine suppliers and intermittent refurbishing business are pivotal in overcoming the challenges identified, namely, traceability and human subjectivity in tool condition assessment. The study demonstrates that technology providers, intermediary refurbishing businesses, SMEs and other stakeholders operating in the metal cutting tools sector must be involved throughout their lifetime to avoid suboptimal results, exchange information, and inspire industrial actors to support the circular economy.

Tidskriftsartikel (refereegranskat)abstract
- Recently, offset contracts have become more complex. For the seller to carry through and review the effects and the demands of an offset contract, they need a framework.The paper identifies five main differences between outsourcing and related offset, which are translated into activities to be included in a suggested related offset framework. The paper is based on an in-depth case study of a related offset business at Saab, a Swedish military aircraft producer. The analysis compared the studied case with an existing outsourcing process identified in literature. The paper contributes by providing an overview of the activities taking place during a related offset process and showing the effect of the different hierarchical levels involved in the process on the efficiency of the fulfilment of the offset business. This paper is based on a single case study, and the suggested differences should be verified through further case studies.

On Safe Collaborative Assembly With Large Industrial Robots
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis pertains to industrial safety in relation to human-robot collaboration. The aim is to enhance understanding of the nature of systems where large industrial robots collaborate with humans to complete assembly tasks. This understanding may support development and safe operations of future collaborative systems.Industrial robots are widely used to automate manufacturing operations across several industries. The automotive industry is the largest user of robots and have identified robot-based automation as a strategy to improve efficiency in manufacturing operations.Recently, a class of machines referred to as collaborative robots have been developed by robot manufacturers to support operators in assembly tasks. The use of these robots to support human workers in an industrial context are referred to as collaborative operations.Presently, collaborative robots have limited reach and load carrying capacity compared to standard industrial robots. Large/standard industrial robots are widely used for applications such as welding or painting. They can, in principle support operators in assembly tasks as well.Two laboratory demonstrators representing the final results from a series of research activities will be presented. They were developed to investigate issues related to personnel and process safety while working with large industrial robots in collaborative operations. The demonstrators were partially based on assembly workstations that are currently operational and they exemplify challenges faced by the automotive industry.Demonstrator-based Research, a methodology for collaborative research that emphasizes development of demonstrators as a research tool, forms the rationale for carrying out research operations presented in this thesis. An evaluation of the laboratory demonstrators by industrial participants suggests an increased interest and confidence in collaborative operations with large robots. The demonstrators have served as a tentative platform for participants to identify and discuss manufacturing and safety challenges in relation to their organization.A main outcome presented in this thesis relates to specifying requirements for introducing robots in a human-populated environment. Introducing robotic systems in new environments requires reconsideration of the nature of the hazards particular to the domain. An analysis of the laboratory demonstrators suggest that, in addition to hazards associated with normal functioning of the system, limitations in human cognition must be considered. These results will be exemplified and discussed in the context of situational and mode awareness. Additionally, a model of a collaborative workstation will be presented in terms of three constituents – workspace, tasks and interaction.This is particularly significant considering the direction of present-day research aimed at introducing robots across various industries and working environments. In response to this trend, this thesis discusses the relevance of Interactive Research and its emphasis on joint learning that goes on between academic researchers and industrial participants as a valuable principle for collaborative research.

Tidskriftsartikel (refereegranskat)abstract
- Robot safety standards defines Collaborative Operation as a state in which purposely designed robots work in direct cooperation with a human within a defined workspace. That is, an operator and an industrial robot complete assembly tasks at the collaborative workspace. A prerequisite to ensuring safety during all phases of operation is an understanding of the nature of hazards pertinent to collaborative systems. An automotive assembly station, where plastic panels are assembled on a continuously moving line, formed the basis for research operations meant to understand safety issues when a large industrial robot aids an operator in assembly tasks. This led to the development of a laboratory demonstrator whose design and functioning will be presented in this article. Additionally, the hazards identified during risk assessment along with measures to mitigate the associated risks will be presented in order to highlight the nature of hazards pertinent to collaborative systems.

Tidskriftsartikel (refereegranskat)abstract
- The perceived benefits of large industrial robots for collaborative operations are characteristics such as long reach with heavy load carrying capability. Collaborative operations refers to situations where operators and robots share a workspace to complete tasks in close proximity. This mode of operation coupled with the physical characteristics of large robots represents high risks to injury and for these reasons, the safeguarding of the workspaces needs to be achieved in conjunction with the tasks to be performed within the workstation. This article will detail two workstations that was developed in a laboratory environment and are partial results of a research project titled ToMM2, whose aim was to understand safety issues associated with collaborative operations with large robots.

Tidskriftsartikel (refereegranskat)abstract
- In order for humans and robots to collaborate on an assembly line, safety of operations is a prerequisite. In this article, two assembly stations where a large industrial robots collaborate with humans will be analysed with the aim to 1. determine the characteristics of hazards associated with human-robot interaction and 2. design solutions that can mitigate risks associated with these hazards. To support the aim of this article, a literature review will attempt to characterize automation and detail the problems associated with human-automation interaction. The analysis points at situational awareness and mode-awareness as contributing factors to operator and process safety. These underlying mechanisms, if recognised by the risk assessment team as hazards, can mitigate risks of operator injury or production delays. This article details the function of visual and physical interfaces that allow operators to comprehend system-state in order to avoid undesirable situations.

Konferensbidrag (refereegranskat)abstract
- It has been shown that large robots can be safely installed for human-robot collaborative assembly cells in experimental setups. It has also been found that these installations require demanding considerations of a significant number of layout and safety parameters. This indicates that successful commercial implementations will require a resource efficient model for production system design that anticipates utilization of large robots in collaborative settings. Experiences from experimental setups have been used to explore a basic model for such production system design, to stimulate a discussion regarding what model characteristics should be tested and validated in future research.

Tidskriftsartikel (refereegranskat)abstract
- Collaborative robot installations often mean man-machine workspace sharing. This mode of operation can lead to reductions of tact time and work space requirements. We have analyzed potential further benefits of man-machine collaboration, where operators and powerful robots share workspace, cooperating when lifting and handling large objects. We found that this mode of operation has the potential to generate economic advantages by reducing the need for manual operators and lifting tools and by offering new opportunities for component logistics.

Safety Assessment Strategy for Collaborative Robot Installations
- 2017
-
Ingår i: Robots Operating in Hazardous Environments. - : InTech. - 9789535136798 - 9789535136804
-
Bokkapitel (refereegranskat)abstract
- Industrial resource efficiency can be improved if the safety barrier between humans and robots is removed, as this enables operators and robots to work side by side or in direct collaboration to solve a task, usually referred to as a collaborative robot installation. Even though technology development makes the barrier removal ever more feasible from a safety perspective, this still produces a possible hazardous working environment, and safety assessment strategies are crucial. A wide area of knowledge is required to assess all fields that can help ensure safe human-machine interaction. Here the focus is primarily on providing a description of the key fields identified, including how operators psychologically accept working with robots, and providing a cursory description of the research front for each individual field. In addition to covering a large number of parameters, the assessment strategy also needs to be cost-effective. A significant part of all parameters that can be considered when attempting to produce optimized and cost-effective collaborative robot installations will also have a direct impact on operator safety. Hence, assessments for safety, and assessments for cost-effectiveness, cannot be separated, and are treated as two objectives that need to be viewed in sync.

An outlook on multi material body solutions in the automotive industry – possibilities and manufacturing challenges
- 2016
-
Ingår i: SAE Technical Paper Series. - Detroit (MI), USA : Society of Automotive Engineers. - 0148-7191.
-
Konferensbidrag (refereegranskat)abstract
- In the automotive industry, mass reduction and lightweight design is a continuing trend that does not show signs of declining. When looking at where to reduce weight in a vehicle, the body is a preferential subsystem due to its large contribution to overall mass and the stability of body composition over a specific model range. The automotive industry of today moves toward a greater differentiation in materials that compose a car, which can be seen in the several different multi material vehicle bodies that have been introduced by manufacturers in recent years. But while mixing materials may contribute to a good compromise between weight reduction and vehicle cost, it also proposes a number of challenges that need to be addressed. Among other material factors, the different coefficients of thermal expansions might introduce new stresses during painting and curing. Joining processes and possible chemical reactions between materials also needs to be taken into account, the same with the question of whether to integrate or differentiate different functions in a system. If the manufacturing plant uses mixed model assembly lines, design of end effectors for gripping multiple different materials is another challenge not previously encountered in this context. In this paper, a number of production and manufacturing related challenges are discussed, and the authors highlight different areas where the requirements of design engineering tools needs to be evaluated for these new multi material concepts and design decisions in order for automotive manufacturers to ensure future market competitiveness.

Including Student Case Projects in Integrated Product and Production Development Research – Methodology Description and Discussion
- 2016
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Within integrated product and production development research, casestudies needto be performed for data gathering purposes. Today, there are two commonly used ways to perform this research; observingindustry projects orhaving the researchers perform the projects themselves. The first option can pose data access and IPRissues, and the second optioncomes with biasing risks. Another approach is to work with studentcaseprojects, givingstudents interesting projects and findinga solution to mediate both data gathering opportunity and biasing risks. This approach has been tested at Linköping University, with students performing projects in the Vinnovafunded Production 2030 –Large Scale Production in Mixed Materials project. Two larger student case projects have been performed on the topic of material substitution and mixed material solutions within the automotive industry.In this paper, the method used to include student projects is presented along with identified benefits and drawbacks. Including student case projects in research have shown to be beneficial in research on processes, projects and methodology, but needs to be complemented by data fromindustry projects and the researcher ́s own work within integrated product and production development in order to create a more reliable analysis with high level of detail.

On Material selection and its consequences in product development
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Technological development, and increased demands on sustainable solutions, have impacted the development of new products. New products need to be more efficient, and there are increased possibilities for a more diversified and informed decision regarding what materials are used in the product. However, how can engineers and designers be helped in their efforts to make better decisions regarding materials?In this research, carried out via multiple case studies and action research, behaviors regarding material selection and material management are examined. The data has been collected using participation action research, observations, and interviews as the primary sources of information. The author has conducted participation action research integrated into an industrial environment, multiple case studies using students in industrial design engineering have been done, and the researcher has performed interview studies with industry representatives. The behaviors described in the empirical studies are contrasted with basic decision theory and analysis of established product development methodology, asking the questions: Are basic assumptions built into models and methods taught to designers and engineers valid?The research presented in this thesis shows that there are personal, technical, and organizational aspects to selecting and managing materials in product development. This work has also shown that assuming rationality, something that is built into methods and models as well as taught to engineering students, is not valid in decision-making; human beings are not rational, and entirely rational decisions are not possible due to the vast data and prediction needs to be able to make entirely rational decisions. Even when assuming some variant of bounded rationality, multiple factors described in decision theory are not acknowledged in product development methodology. Two of these can be described as identity (both personal and professional) and mental models of materials.The discrepancy in how decisions are described in decision theory and how methods for decision-making are designed in product development risks inhibit the introduction of new and more sustainable materials in products. This could be because non-rational aspects of decision-making are incorporated in the decision-making under the assumption of rationality. It could also be because of the mental models of materials affecting what the designers and engineers think they can do with a particular material. These behaviors make the risks of introducing new materials too big for a designer or engineer to accept.Outcomes from this research show that additional data will not be enough to persuade designers and engineers to select new material to its fullest extent. This can slow down sustainability improvements in products. To counter this, it is suggested that the personal and non-rational side of decision-making is acknowledged and valued, that visions and ideology are used to encourage the introduction of new materials rather than relying on technical or economic aspects, and that designers and engineers are encouraged and enabled to take higher risks and evaluate more “unknown” parameters.To fully implement these suggestions, the following three things need to happen:A: Design and engineering education needs to teach students how to have more flexible mental models of materialsB: Industry should find ways for designers and engineers to experiment further and learn (both on an organizational and personal level)C: Academia should further investigate how behaviors, mental models and habits affect product development and design work, especially regarding material selection and material management.

On Material Substitution in Automotive BIWs – From Steel to Aluminum Body Sides
- 2016
-
Ingår i: 26th CIRP Design Conference. - : Elsevier. ; , s. 683-688
-
Konferensbidrag (refereegranskat)abstract
- Weight reduction and material substitution are increasing trends in the automotive industry. In this project, the task of substituting the steel body side in the monocoque of a large SUV towards an aluminum body side was investigated through a design engineering approach adopting a breadth-first analysis method. One conclusion based on the analysis is that the choice of joining technology would become arbitrary due to the breadth-first approach. In this paper, the authors present their findings from the aforementioned case, including the challenges with switching between materials with fundamentally different properties when performing material substitution projects. The possibility of having taken a depth-first analysis approach, and the possible effects on the project result, is discussed.

Product development in the Swedish Automotive industry: Can design tools be viewed as decision support systems?
- 2015
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Design engineers working in the automotive industry have to take many design decisions, based on numerous diverse criteria. This results in a high workload of complex decisions. One way to reduce decision complexity and improve decisions could be to improve design tools. Decision support systems (DSSs) have been used in a managerial context to improve decisions. In this article, the authors assess whether design tools generally can be viewed as DSSs. A combination of literature review, surveys and qualitative interviews with seven design engineers was used to assess whether current design tools function as decision supports in product development. Although the specific design context needs to be considered, this study’s results suggest that design tools can generally function as DSSs. In future work, the adaptability to different problem solving patterns needs further in-depth research in the form of individual studies for specific tools in specific contexts.

University as a Laboratory : Exploring how engineering education can support industrial needs
- 2018
-
Ingår i: NordDesign 2018. - 9789176851852
-
Konferensbidrag (refereegranskat)abstract
- Universities have two major tasks; generating knowledge through research and educating students for academia, the public sector and the industry. In this paper, the authors explore how engineering education can support industrial needs on two fronts: creating a case study platform for research and preparing graduating engineering students to become more capable engineers when beginning their working life in industry, by applying the ""University as a laboratory"" concept. ""University as a laboratory"", as coined by Henriksson (2017), means that research-based case study projects are brought into educational courses where students are assigned to work as engineering designers, and researchers can observe problem solving patterns and evaluate different methodologies (also presented by Henriksson and Johansen (2016)). Though the concept have been presented earlier (Henriksson and Johansen 2016, Henriksson 2017), a more thorough evaluation is in order to further understand the effects of integrating research and education in the ""University as a laboratory"" concept. This is done through the performance and evaluation of a research-based engineering design education project in collaboration with automotive industrial partners; a project on lightweight and sustainable product and production development. The study evaluates three aspects of the project; the researchers' view, the teachers' view and the students' view. Data on all three aspects has been gathered through group interviews, observations and written assignments during the project, as well as interviews with participating students one year after the end of the project and workshops with researchers and teachers involved in the project. Analysis has been done on a qualitative basis, to investigate whether case projects are suitable for deep understanding in engineering fields and whether project courses are suitable to test different approaches of integrated product and production development.

Konferensbidrag (refereegranskat)abstract
- The remanufacturing industry currently relies significantly on manual work when, for example, sorting and disassembling. Due to several issues, including process time and sequence, operations number, disassembly planning and scheduling, process cost, and performance measurement, it is challenging to stay competitive. Based on this, it is assumed that more extensive use of robots and automation in these industries can facilitate higher efficiency and better work conditions. This research paper aims to explore how remanufacturing of car components can be made automatic. The paper describes a case where a specific car component was selected and a specific step in its remanufacturing process explored from the perspective of automating that task. When conducting remanufacturing of the selected car component, some machines are used for the testing, cleaning, and grinding of materials. However, all assembly work is done manually. In collaboration with the case company, the process step of applying sealant for the assembling of a lid that covers electronic components was selected. The demonstrator shows that it is possible to apply sealant with a human-robot layout with a good result. One of the advantages of using a robot for this step is that a high-quality result was achieved.

Tidskriftsartikel (refereegranskat)abstract
- Resource-efficient production including life-cycle approaches was stated as early as 2002 as the only way forward for the industry. Now, twenty years later, this is a reality in many ways. This represents a challenge to manufacturing small- and medium-sized enterprises (SMEs) due to a disruptive industrial environment as well as changing market needs that require more capability to manage predictable as well as unpredictable changes. This paper explores some aspects manufacturing SMEs must manage, such as developing new capabilities to stay competitive in a disruptive industrial environment with uncertainties in supply chains, technologies, energy costs, changes in customer demands, and circularity. This paper presents a conceptual guideline for assessing the capabilities to develop as a manufacturing SME in a circular industrial environment. One way to manage this transition towards circularity in an industrial environment can be to develop transdisciplinary collaborations between different stakeholders and competencies.

An Economical Analysis on A Strategic Investment in an Assembly Line : Case Study at Ericsson Mobile Communications AB
- 2001
-
Ingår i: Proceedings of the 16th International Conference on Production Research.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- During the last four years the global annual production of mobile telephones has increased four times. To Ericsson Mobile Communications AB’s supply unit in Linköping, Sweden, this has been a tremendous challenge. The supply unit has increased the produced volume of mobile telephones six times during this period at the same premises. The strategy for the production-engineering department was to change the manual assembly line into an automated assembly line. The automated assembly line was built up with SONY smart cells. During 1998 the volumes increased rapidly and the automation strategy where copied to the test stations for the mobile telephones.This paper discusses the importance of how to link a manufacturing strategy to economical calculations. A case study at Ericsson Mobile Communications AB shows how financial calculations was used when changing from manual testing to automated testing of mobile telephones. Even though all benefits were not accounted for, the studied automation project for automated board test had a calculated pay back period of 7 months. The decreasing production volumes for mobile telephones made that the real yearly cost for the investment increased dramatically compared to the calculated investment cost. The decision-makers need to analyze the risks in an investment calculation due to the uncertainty in data used in the calculations. For example, it can be difficult to analyze the risks depending on the difficulty to predict the development for the product market and the future product volumes. The investment calculation result can also differ depending on who is delivering the numerical data that are included in the calculations.

- Small and medium-sized enterprises (SMEs) that are manufacturers are challenged during the coronavirus pandemic since their customers have been locking down their production due to different reasons. This is a disruptive and unpredicted situation for manufacturing SMEs and at the same time a lot of possibilities for manufacturing other types of products is shown. This paper will discuss challenges for SMEs in such a disruptive situation, and reflect if it is possible to be prepared? And if so or not, what can we learn for future and reducing the risks if or when next pandemic situation occurs.

Challenges for Swedish Wood Furniture Manufacturers : Its Handcraft Tradition versus Modern Production Technologies
- 2009
-
Konferensbidrag (refereegranskat)abstract
- The Swedish wood furniture manufacturers are facing an increasing competitiveness from large import of furniture to the Swedish market. One way to meet this is to combine traditional handicraft with a change towards more CNC machines and automation in the production lines. This paper describes a performed case study in the Swedish furniture industry based on interviews and observations from walk the production in all companies.The companies illustrate three main types of production systems; 1) Complete manufacturer: Nearly all manufacturing and final assembly in-house; 2) Cross-over manufacturer: Some components from suppliers, manufacturing and final assembly in-house; 3) Collaborative depending manufacturer: All components from suppliers and final assembly in-house. This case study has identified a gap in the more handicraft intense furniture industry in Sweden which is the connection between the furniture design – product development – manufacturing.

Konferensbidrag (refereegranskat)abstract
- Assembly is crucial in the automotive industry, and regulations aimed to increase circularity impact the production systems. From this perspective different strategies are emerging related to sustainability and to the End-of-life Vehicles directive, perspectives often captured by “R-words” like Reuse, Recycle, Rethink etc. This paper is based on a literature search inspired by different R-words related to circularity and assembly in the automotive industry in combination with industrial workshops on the same theme. The results explore what challenges to manage during the ongoing green transition in the context of assembly in automotive. Recover, Repair, Reuse and Recycle are the most common terms found in the literature. Furthermore, Remanufacturing stands out as of particular interest to the automotive industry. However, based on the industrial workshops, Rethink as a collective word is an important perspective as well. The conclusions indicate that digitalization can be an enabler but also that there is a need for developing a common understanding about definitions and utilization of engineering tools supporting circularity.

Collaborative Product Introduction within Extended Enterprises
- 2005
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The trend of outsourcing within the electronic industry has contributed to the creation of new types of extended enterprises. These extended enterprises must be able to manage a challenging situation with shorter product life cycles and increased collaboration between companies during the vital product introduction process. For the electronic industry, which is currently acting in an “era of hyper-competition”, it is a challenge to implement an efficient and flexible collaboration within an extended enterprise during the product introduction process. In the product introduction process, a product design is prepared for and transferred into production.During the course of this research, the electronic industry has changed continuously. Empirical data were first collected within an Original Equipment Manufacturer (OEM) that was responsible for its own production. Based on a strategic decision at the OEM, a new extended enterprise was established. In general, these new extended enterprises within the electronic industry consist of: a “product owner” in the form of an OEM that owns the product design and its brand; a “producer” in the form of an Electronic Manufacturing Services (EMS) company that is responsible for the production; and suppliers of services, material, components, equipment etc. However, in the later stages of this research the studied EMS was responsible for the product introduction, production and distribution of the product to the end user. In order to compare and contrast trends and lessons learned in similar industries, case studies within the mechanical engineering and aerospace industries also were performed.The dissertation primarily describes the process of collaborative product introduction (PI) within the electronic industry, and presents among other things a number of general conditions for efficient collaborative PI within an EE in that industry. First, a clearly communicated definition of what is included in product introduction is needed. A second condition is that early participation from all involved partners in the EE’s product introduction process supports efficient collaboration. Third, clear communication and information handling within the extended enterprise – both internally and externally – was found to facilitate collaboration. Fourth, business approaches should be built on trust, reliability and respect for each other’s competence. Finally, the importance of cultural awareness, both between different companies and countries, cannot be ignored. This research also presents a framework for supporting collaborative product introduction within an extended enterprise, which serves to both synthesize and summarize much of the research.

- Accelerating technological developments and increasing competition make it important to secure the development of production solutions that allows for resource efficient layouts and continuous improvements. When developing production solutions, the usage of digital tools is an important asset that supports production preparation engineers in their work. However, the emerging possibilities to design production layouts where the operator and a robot collaboratively share a task, add more challenges for production preparation engineers. The production layout become more complex, with more parameters to analyze for a safe and secure working environment, supporting a safe interaction between technologies and operators. The design of human-robot-collaborative (HRC) layouts, with ever shorter product life cycles, could benefit from an increased use of digital tools, as ever more powerful simulation and design tools are available on the market. This paper will explore digital tools (such as simulation, emulation, visualization) and their potential contribution for different HRC layout designing steps. Based on this, the needs to be reflected in a guideline for a digitalized production preparation process will be explored from the perspective of developing a human-robot collaborative layout.. © 2022 The authors

Konferensbidrag (refereegranskat)abstract
- In the global manufacturing business, more sustainable solutions are needed, and in parallel manufacturing companies also need a capability to react quickly to unpredictable changes in a highly competitive marketplace. This has become more visible at the start of the Covid-19 pandemic when many companies experienced manufacturing constraints such as a shortage of raw materials as well as a need for transformation of manufacturing facilities to produce vital items. In parallel, many manufacturing companies also are in the transition towards more digitalization as well as automation in their facilities, which can contribute to the capability to manage unpredictable changes, but it might also contribute to challenges. Therefore, the digital transformation of production processes with innovative and emerging technologies, and the contribution and challenges of these technologies are of importance to understand. Specifically, in which way these emerging technologies contribute to a resilient and sustainable production process from a technological perspective, and how these production processes might contribute to achieving sustainability goals. Based on findings from literature an analysis is performed aiming to explore the emerging technologies perspective in relation to capabilities as well as challenges regarding implementing solutions that contributes to a resilient and sustainable production process. The overall findings indicated the importance of having flexible production facilities to be able to respond to customer expectations. However, the digital transformation of production facilities demonstrated other challenges such as energy consumption, lack of skilled personal, low level of standardization, financial sources, and security problems. To conclude, the relationship between the content of resilient and sustainable production systems that are influenced by emerging technologies are suggested, with the ambition to contribute to a more competitive manufacturing company that increase its capability to manage customer expectations.
