Designing longer-lasting connected products is a complex problem, as they include multiple components such as connectivity chipsets, batteries etc. Discussing longevity concepts with industry experts can therefore be challenging due to a lack of framework and ambiguous terminology. In this paper, we are proposing a tangible token kit called Connected Product Lifetime Extension Tokens (CPLET) that allows us to elicit data in interviews. CPLET includes longevity concepts derived from Design for sustainability and Sustainable ICT literature. We utilized CPLET as conversation enablers during semi-structured interviews with 16 participants from nine different companies in the audio industry. This paper introduces CPLET, and an overview of the longevity concepts currently applied to improve the longevity of connected sound products. Utilising such a complementary method contributed to richness of the data, simulated further reflections. guided and broadened the discussions and mitigated terminology confusion.

Repair activities have been in a long-term decline in the industrialized world; however, for the circular economy and a more sustainable future, repair is essential. To support repair activities through design, we adopt a practice theory lens to examine the user's computer self-repair dimension. Based on qualitative data from semi-structured interviews and think-aloud sessions with participants with different levels of repair experience, we present a model that can help designers understand and identify the typical factors of computer self-repair practice. This model can aid designers in holistic design solutions that enable, recreate, and continue computer self-repair practice and design systems and solutions accordingly.
