Happy moments: A well-being driven design of a Car2Go

User well‐being is increasingly addressed in design and design research. Previous work has proposed a design for well-¬‐being framework that includes three main ingredients: pleasure, personal significance, and virtue. While useful for analysing the well-¬‐being impact of existing designs, it is difficult to use the framework as a resource in well-¬‐being focussed design projects. This paper presents a design case study in which two key challenges have been addressed. The first is to understand how to identify relevant pleasures, personal significances and virtues in the context of design practice. The second is to understand how design concepts can be developed that integrates these three ingredients in a meaningful way. The design case was to develop a car interior for a car sharing service. The first challenge was addressed with two user studies where it was found that especially conflicts or tensions between ingredients stimulated design creativity. The second challenge was addressed by including the factor of time in the design concept (creating a concept in which experiences unfold over time). The design case is presented and the techniques that were used to address the well-¬‐being-¬‐specific design challenges are discussed and reflected on.
