Towards a reference architecture for digital product passports in engineering 1Fraunhofer IEM, Germany; 2Heinz Nixdorf Institute, Paderborn University, Germany Digital product passports (DPP) are intended to provide reliable, interoperable information throughout the product lifecycle, enabling compliance, transparency, and circularity. This paper seeks to address the question of how a DPP can be effectively implemented in the field of engineering, developing a referenced, industry-independent architecture for this purpose. The layers for data, communication, logical architecture, functions, and potential are derived from regulation and practice; integration, interoperability, and validation requirements are discussed using a use case. Inside and outside perspectives on design for circularity: barriers across design producers, consultancies and SMEs Lund University, Sweden Despite the many circular economy (CE) design frameworks, implementation is limited. This study interviews six Swedish design firms (producers/consultancies, small/large) to compare CE barriers. Results show small producers face more value chain challenges, while large producers focus on design. Consultancies emphasize economic/legal factors. Organizational silos and perceived costs are universal barriers. The findings highlight the need for tailored CE approaches: SMEs require resources to influence suppliers, while large firms need better methodologies for internal organizational change. A circular economy-oriented early design and optimization approach for structural components of rechargeable energy storage systems 1Institute for Engineering Design, Technische Universität Braunschweig, Germany; 2ARRK Engineering GmbH, Germany; 3Institute of Machine Tools and Production Technology, Technische Universität Braunschweig, Germany This study presents a method to design sustainable structural parts of a Rechargeable Energy Storage Systems using Design for CE and Computational Optimization. Principle solutions are developed and combined with sustainability criteria being a key factor in the concept evaluation. The battery tray, a subsystem of REESS, serves a case study in which intrusion, mass, and LCA are optimized by varying the recyclate, UD tapes and design. The resulting Pareto front reveals trade-offs between intrusion, mass and LCA results and highlights the potential to reduce environmental impact in early design. The longevity trinity: a review and framework conceptualisation of design strategies and attributes for value retention and extended furniture life Linköping University, Sweden This study synthesises interdisciplinary research on design strategies and attributes for extended product life of furniture. Through an integrative literature review, it develops the heuristic Longevity Trinity framework, comprising technical, functional, and emotional orientations. The framework consolidates dispersed design principles and highlight how the physical and psychological properties of furniture interact with the component of time, positioning product longevity as a design problem of continuity; continuity of materials, usefulness, and meaning across multiple lifecycles. | ||
