DESIGN FOR LONGEVITY - A FRAMEWORK TO SUPPORT THE DESIGNING OF A PRODUCT'S OPTIMAL LIFETIME

• Extending the lifespan of products and parts is seen as a solution in the transition towards a circular economy. There are many proposed design approaches argued to facilitate this. However, extending the lifespan of products and parts is not always desirable, and product developers should instead strive to design for a specific longevity; the product's optimal lifetime. The latter in turn depends on many various contextual factors, and this paper has identified the three main contextual factors as; the user, the business, and the resource efficiency. Considering these three appropriately can help product developers to define their product's optimal lifetime. Altogether, these components promote the mindset of Design for Longevity. Specifically, as extracted from this paper: “Design for Longevity aims at designing products with an optimal lifetime, where optimal means taking the user, the business and the resource efficiency perspectives into account when designing the life of a product”. A Design for Longevity framework is proposed and evaluated in this paper, and it is concluded that the proposed Design for Longevity framework can support product developers to implement the Design for Longevity mindset.
