Emotional Durability Design Nine—A Tool for Product Longevity

How can we develop products that consumers want to use for longer? The lifetime of electrical products is an ongoing concern in discussions about the circular economy. It is an issue that begins at an industry level, but that directly influences the way in which consumers use and discard products. Through a series of workshops and knowledge exchange sessions with Philips Lighting, this paper identifies which design factors influence a consumer’s tendency to retain their products for longer. These were distilled into a guiding framework for new product developers—The Emotional Durability Design Nine—consisting of nine themes: relationships, narratives, identity, imagination, conversations, consciousness, integrity, materiality, and evolvability. These nine themes are complemented by 38 strategies that help in the development of more emotionally engaging product experiences. We propose that the framework can be applied at multiple points during the new product development process to increase the likelihood that ‘emotion building’ features are integrated into an end product.
