Robot assisted framing : A concept for securing geometry in flexible production
- 2008
-
Rapport (refereegranskat)abstract
- The paper describes a concept for securing the geometry in flexible production based on robot assisted framing. This uses the robot(s) as an active device during change-over between product variants and it is assumed that product variants can be produced in any mixed order. The case under study is cabs for trucks which in traditional production require large and heavy equipment which is above the payload of any robot. The idea within this study is to use carbon fibre composites in the fixtures in order to reduce the weight and through this make it possible to use the robots in assisting the framing process. The current work involves a generalization of the principle both considering the design of the fixtures with respect to issues such as materials properties and design principles, and design of the production system.

Concurrent Design of Product and Package - Extending the Concept of IPD

Konferensbidrag (refereegranskat)abstract
- As a result of the globalisation of the world economy, many enterprises that previously confined their business activities to national markets are now focusing on broader international markets, thus forming the basis for the establishment of global enterprises. In addition to the extension of markets, these global companies also seek cost reductions through scale economics in logistics, marketing, product development, production and purchasing, and through focused manufacturing and/or assembly operations - Christopher [5], Porter [10]. In order to contribute to the establishment of global enterprises, an interdisciplinary research project has been launched at the Department of Design Sciences, Lund University, Sweden, as a collaborative effort between two of its divisions Machine Design and Packaging Logistics. The overall objective established for the project is to: facilitate the establishment of successful global enterprises by providing methods, techniques and an overall procedure model for integrating packaging logistics into the product development process.” By extending the concept of Integrated Product Development (IPD) to include the concurrent design of product and packaging, increased efficiency and effectiveness in the product development process are conceivable. Apart from the apparent advantage of reducing the time to market, environmental impacts in terms of a reduction in the consumption of raw materials due to the possibility of facilitating a “tailor-made” packaging of the product are also conceivable. As a result of the development of more efficient and effective packaging of the products, a reduction in emissions from the distribution of the products is also expected. For the development of the product-to-be, the packaging might provide alternative, less costly, solutions; this especially applies to those products, which have to withstand major structural loads during the distribution phase of the product life cycle. The overall concept of integrating relevant activities from the packaging logistics area into the IPD process has been introduced in a previous paper - see Bjärnemo et al [1]. In the paper presented here, the main objective is to:” establish the industrial relevance of introducing the concurrent design of product and packaging thus supporting or rejecting the key element in the previously developed integration concept.” The secondary objective is to: “obtain more detailed information on the actual handling of the interaction between product and packaging design in industry.” The latter information is intended to be used either for the further development of extended IPD concept or for providing a more detailed view why the integration concept has to be reacted. In order to obtain the information requested, an explorative survey has been performed in Swedish industry. The findings from this survey and its implications, as outlined above, are reported here

Konferensbidrag (refereegranskat)abstract
- Extending the product development process to also include the concurrent design of product and packaging is expected to increase efficiency and effectiveness in the development process. Apart from the obvious advantage of reducing the lead times of the development project, improving environmental impact by reducing the consumption of raw material due to the possibility of facilitating a "tailor made" packaging of the product is also anticipated. For the development of the product-to-be, the packaging might provide alternative, less costly, solutions. The main objective is to establish the actual interest in or need for introducing concurrent development of product and package in the product development process. In this paper the findings from a literature review and two surveys are reported. The surveys are performed in 40 Swedish companies, half of them in the food industry and the other half in the pharmaceutical industry. From an overall perspective of competitiveness, the findings demonstrate not only the relevance of introducing concurrent development of product and packaging in the product development process, but also that this introduction should be based on the concept of integration.

Towards an Integrated Design of Product and Packaging

Konferensbidrag (refereegranskat)abstract
- The globalization of the world economy has forced many enterprises to merge and/or to acquire enterprises worldwide. in the next phase of this development, rationalization calls for specialization of functions such as product development and production in one or a few sites, if not being outsourced to external suppliers. These new divisions of the “virtual” enterprise have to collaborate within internal and external networks, where efficient and effective transportation, handling and storing of intermediary and final products is a must. In order to obtain this objective, an integration concept of the design of product and packaging has been proposed by Bjärnemo et al. [ 1]. The acceptance of the need for such a concept in industry has been established by Bramkiev [2]. In this paper an industrially implementable, integrated procedure model for the concurrent design of product and packaging, confined to the product area of mechanical engineering, is presented.

A process model for enhanced integration between computer-based design analysis and engineering design
- 2016

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The findings from a survey in industry and from an extensive literature survey revealed the need for the development of an integrated process model for computer-based design analysis (CBDA) facilitating the interactions in the engineering design process in mechanical engineering on an operational level. CBDA is here confined to the utilization of advanced computational methods and tools from computer aided engineering (CAE), such as computational structural mechanics (CSM), computational fluid dynamics (CFD) and multi-body systems (MBS). In order to facilitate integration to the multitude of engineering design process models in industrial practice, including overall processes such as product innovation and product development, the process model needs to be adaptive and generic. Generic should here be interpreted as not being dependent on any specific type of product, engineering design process, or on any specific type of product innovation and/or product development process models utilized by an enterprise. Resulting from synthesis processes based on the findings from surveys and experiences gained from design analysis projects in industrial practice, the generic design analysis process (GDA) model was developed. The application of the GDA process model is exemplified by four examples, which have been utilized for validation of the process model.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Computer-based design analysis is nowadays of utmost importance for most engineering design projects. However, this brings some challenges, among them that of the collaboration between engineering designers and design analysts. Since they work with, and are responsible for, different areas, they do not necessarily have full insight into each other’s way of working. The issue of integration between the design analysis process and the engineering design process is of major significance for providing an increase in efficiency and effectiveness in engineering design and development of products. In this work, an approach is proposed aiming at providing this increase in efficiency and effectiveness. Based on the analysis of the information workflow between the engineering design process and the design analysis process, a mapping of the necessary interactions between engineering designers and design analysts can be made. The presented approach facilitates this mapping. An application of this approach to an industrial project is also presented.

- In the large majority of product development projects, computer-based design analyses are performed to assess the feasibility of potential technical solutions. As a first step to bring about a deeper understanding of the interactions between the engineering design and the design analysis activities, a survey has been performed in industry. The results of the survey cover: the use of design analysis within product development, the interactions of engineering design along the design analysis process, and the treatment of uncertainties and errors connected to the design analysis activities.

Konferensbidrag (refereegranskat)abstract
- In most industrial product development projects, computer-based design analysis, or simply design analysis, is frequently utilized. Several design analysis process models exist in the literature for the planning, execution and follow-up of such design analysis tasks. Most of these process models deal explicitly with design analysis tasks within two specific contexts: the context of design evaluation, and the context of design optimization. There are, however, several more contexts within which design analysis tasks are executed. Originating from industrial practice, four contexts were found to represent a significant part of all design analysis tasks in industry. These are: 1. Explorative analysis, aiming at the determination of important design parameters associated with an existing or predefined design solution (of which design optimization is a part). 2. Evaluation, aiming at giving quantitative information on specific design parameters in support of further design decisions. 3. Physical testing, aiming at validating design analysis models through physical testing, that is, determining the degree to which models are accurate representations of the real world from the perspective of the intended uses of the models. 4. Method development, that is the development, verification and validation of specific guidelines, procedures or templates for the design analyst and/or the engineering designer to follow when performing a design analysis task. A design analysis process model needs to be able to deal with at least these four. In this work, a process model named the generic design analysis (GDA) process model, is applied to these four contexts. The principles for the adaptation of the GDA process model to different contexts are described. The use of the GDA process model in these contexts is exemplified with industrial cases: explorative analysis of design parameters of a bumper beam system, the final physical acceptance tests of a device transportation system (collision test, drop test, vibration test), and the method development of a template for analyzing a valve in a combustion engine. The "Evaluation" context is not exemplified as it is the most common one in industry. The GDA process model has been successfully used for the four contexts. Using the adaptation principles and industrial cases, the adaptation of the GDA process model to additional contexts is also possible.

Konferensbidrag (refereegranskat)abstract
- Many specific and precise methods that support the mechanical engineering designer's work during the conceptual design phase exist, while only a few general methods address the embodiment design and detail design phases. Our study presents the pattern of the designer's problem-solving activity during the later phases of the design process. This model is in-tended to serve as a basis for further development of tools and methods directly oriented towards the de-signer at work in these stages of the design process. The descriptive model presented here is developed through observations of six designers at work in con-trolled experiments, and follows a previous study published elsewhere.
