- As the world deals with climate change, it is crucial that new products are designed to be more sustainable. Product design strategies which conform to the Circular Economy principles have recently gained attention, which promote sustainability and resource efficiency. However, such strategies require careful consideration of uncertainties and the ways to mitigate them, e.g. by using margins. The pursuit of circularity can inadvertently lead to overdesign as designers strive to mitigate elevated risks, thereby making a product less sustainable. In this paper, we explore this balance.

- A radical shift in technology is necessary to enable future air transport solutions. Sustainability targets for aeroengine manufacturing mean more than reducing CO2 and NOX. The future will open up possibilities and bring new challenges when introducing hybrid- and electrical propulsion technologies using new materials, technology solutions and new business models. This article reports on findings from a longitudinal study and many years of collaboration between researchers and industry experts, where a first-tier aeroengine manufacturer transforms their product development capabilities to enable sustainable product development. The article highlights some activities undertaken and identifies critical challenges and opportunities remaining for a manufacturer of next-generation aeroengine solutions. It is argued that the challenge for aeroengine manufacturers to develop new-generation propulsive technologies will require a systemic change in the undertaking of design and development. The opportunities of sustainable technologies are evident yet require: (1) means to tighter integrate business and technology development, (2) the ability to quantify and assess sustainability impacts of different concept solutions, and (3) means to utilise natural resources, alloys and materials for a circular and life-cycle optimised solution.

- This paper explores the needs and clarify the sustainability challenges in relation to complex lifecycles within the aerospace field. It is an introductory study to understand how to improve the sustainability performance of aerospace solutions and aim to propose a comprehensive sustainability transition roadmap for the Aerospace industry in further research work. Society is increasingly demanding that the aviation industry adopt more sustainable practices, resulting in the formulation of new regulations and policies to limit the sustainability risks of this strategic industry. Existing regulations, such as the EU's Green Deal and the EU's critical raw materials act, are already impacting the Swedish aerospace manufacturing industry. Furthermore, circular economy is gaining significant attention in the manufacturing industry in general and is increasingly considered in aerospace. This exploratory and descriptive research is conducted with support of Swedish Aerospace manufacturers and aim to cover real industrial projects with products at different stages of development. The interviewed companies operate within both civil and governmental aerospace sectors, encompassing the entire spectrum of product development, from radically innovative technology introductions to enhancements made to existing systems and components. This paper highlights current challenges and several focus areas on which the aerospace manufacturers have started to work on and will have in focus for the next 5-10 years ahead. Differences in approach have been identified between early product development phases with radical innovations and more advanced and mature product development. The stakes and priorities are different and it is reflected on how the companies are working with sustainability today. There is a need to balance efforts between developing the right future products, and also improving current ones, to lead the sustainability transformation in the aerospace industry.

Konferensbidrag (refereegranskat)abstract
- Sustainability has shifted from strategically important to business critical for several manufacturing industries. This paper introduces an implementation framework to increase the capabilities in companies to design, develop and offer sustainable product- and production solutions in line with new regulatory strategies and plans. Based on a questionnaire survey, conducted in ten different product development companies representing different industrial sectors, the status and needs of sustainable product development were captured. Further on, a better understanding of the capabilities for a forthcoming digital sustainable product development support, were identified in an action research-based approach with three industrial companies. This paper presents the rational of a digital sustainable product development support, in relation to global sustainability goals and societal dimensions of sustainability transitions. The main results from the questionnaire presents the challenges and needs of capabilities for product developers and design engineers to develop more sustainable solutions in a resource efficient way. The action-based research with the three industrial manufacturing partners resulted in a set of common key activities and detailed requirements for a digital sustainable product development support. Finally, the paper describes a first prototype of a digital platform, i.e. Digital Sustainability Implementation Package-DSIP, and discusses future work. © Proceedings of NordDesign 2022: How Product and Manufacturing Design Enable Sustainable Companies and Societies.

Konferensbidrag (refereegranskat)abstract
- A novel method is presented, including a material criticality list and sustainability compliance index. The method aims to support an estimation of the vulnerability of a product concept due to material criticality and strategically guide early design decisions. A jet engine component design team evaluated the method. It was understood that the method increased communication and clarification regarding material criticality. Further, it became apparent that the method provided a collaboration link between the design team and the business development team.

- Improving structural performance of products is often realized by introducing increasingly advanced and complex materials as well as material combinations. What material to use in products is decided in the early product development phases and has a decisive impact for manufacturing, maintenance and end-of-life. A particular challenge is that the decisions need to be made upfront, where information of the forthcoming product is limited. This paper presents an early product development method to assess the criticality of alloy materials from a resource availability- and sustainability perspective. The method distinguishes itself from previous studies that focus on element criticality on a country level. The method is used to characterize and analyze the criticality of alloys in a three-step process that aims to support product design teams selecting what material alloy to use in early phases of design. It provides a proactive and systematic approach related to critical materials to avoid potential future problems on a long-term basis. The method presented has been developed in an action research-based approach in an aerospace company where a product design team validated and evaluated the material criticality method. The generic nature of the method is likely to be applicable not only to aerospace companies but also to other industries using advanced alloys. An important finding from applying the method in the company case was the clear link between long term business impact and sustainability performance. © 2017 Elsevier Ltd

Tidskriftsartikel (refereegranskat)abstract
- Apparent from the latest pandemic, the dynamics and rate of change in society accelerate on a global scale. Ongoing mega-trends in society, such as digitalization, sustainability, and servitization, fundamentally changes the conditions for manufacturers when developing and providing new products. This study clarifies the combined impact and consequences on product development capabilities in manufacturing firms of the three mega-trends: (i) digitalization, (ii) sustainability, and (iii) servitization. The research is based on a pre-study, complemented with a semi-structured interview study at small, medium-sized, and large Swedish-based manufacturing companies, and a systematic literature review. The research makes evident that the main challenge is to empower engineers and development teams to model, present, evaluate, and develop expected and smart digitalized solutions in a time-limited environment and prioritize the most resource efficient and sustainable solution. Therefore, four complementary support resources are suggested: (i) a knowledge management platform, (ii) a data management platform, (iii) a set of criteria and metrics measuring progression, and (iv) support methods and tools to define, model, and evaluate solutions. When integrated into a digital platform, developers can simultaneously access and process the necessary information needed for sustainable, digitalized, and servitized solutions. © 2020 by the authors.

Konferensbidrag (refereegranskat)abstract
- This paper presents a methodology for integrating failure and lifecycle analysis related to additive manufacturing in a computational multidisciplinary engineering design framework. The specific goal of this framework is to quantify the impact of component design decisions on system-level performance in order to assess alternative manufacturing, re-manufacturing and repair strategies from both technical and business perspectives. The ultimate objective of this research is to enable such considerations in the early product design phases, where sufficient degree of freedom exists to identify component design solutions that can facilitate and accommodate different manufacturing and repair techniques that impact the entire lifecycle. The developed methodology is demonstrated by means of a jet engine component where repair strategies are included as variables in the computational design process. Numerical results confirm that these strategies can be used to trade among design attributes such as lifecycle cost, weight, and performance.

Digitalisation, sustainability and servitisation : Consequences on product development capabilities in manufacturing firms
- 2018

Ingår i: DS 91. - : Linköping University Electronic Press.

Konferensbidrag (refereegranskat)abstract
- This paper investigates the impact of the three mega-trends (1) digitalisation (2) sustainability and (3) servitisation on design and development capabilities in manufacturing companies. First, technological advancements have created both product opportunities, and new aids, captured in e.g. the Industry 4.0 paradigm, and intensively driving digitalisation of businesses, that, besides the technological challenges, cause new challenges and problem areas, such as information ownership and shared long-term responsibilities. Second, the need for sustainable solutions increases the focus on the design of circular, resource efficient and radically new technological solutions to be designed with a total life cycle perspective in mind, through use phase, repair and overhaul, until recycling and end-of-life. Third, and finally, the classical roles for suppliers, integrators and users are being changed as servitisation and Product-Service Systems (PSS) offerings affect both products and businesses, and ultimately entire value networks with new constellations of business partners contributing to the realization of solutions for customers. This paper builds on a conceptual literature review to identify relevant information about the three trends regarding their impact on design and societal development. In addition, a semi-structured interview study was conducted to investigate possibilities and challenges that four different types of manufacturing companies perceive today with respect to the mega-trends, and more specifically how these trends impact the design and development capabilities in the studied companies. Results from this empirical study show that digitalisation is viewed as an opportunity to find new solutions to meet customer needs and be competitive at the future market. Sustainable Product Development (SPD) was instead primarily to fulfil requirements and legislation. However, it was clear that some manufacturers start to see market forces as a driver. PSS can be seen as a means to create new solutions, often with digital tools as facilitator. Altogether, the literature study and the empirical data show that increasingly, designers are expected to design entire solutions, as opposed to merely artefacts. This implies that designers need to consider not only the product performance and cost, but products’ and solutions’ behaviour and impact over complete life cycles, developed and organized by business networks together with several suppliers and other partners with different capabilities. The basis for the designer is a technology mix comprising services, software, electronics and hardware, bundled into offerings in new business models, interlinked with new digital opportunities. Moreover, it is clear that the three trends do not represent stand-alone perspectives but affect one another in an intertwined way. To achieve long-term effects, the sustainability issues need to be integrated with many other subject areas, and implemented simultaneously as digital solutions, e.g. digital twins to physical artefacts are conceived, and value creating networks are being built up. Obviously, these three trends affect the need for change in product design capabilities and escalate the challenges of the integrated product development viewpoint, in a way that is difficult to master for individual engineers. Support for design and development work is needed that takes into account the mega-trends digitalisation, sustainability, and servitisation.
