Categories and Design Properties of Inherited Long-Lasting Products

As a counter-reaction to the increasing speed at which products are consumed, companies have embraced the idea of designing products that last longer. To understand characteristics of long-lasting products, this paper examines the product categories and design properties of products that are inherited, and thus have a prolonged product lifetime. Based on previous research, we propose a theoretical framework with product categories and design properties for inherited products. We then deploy this framework on an empirical dataset of 175 inherited products that are identified through participants’ self-assessments. These are then analyzed in respect to 18 product categories and three overall groups of design properties: emotional properties (memories and brand), functional properties (functions), and aesthetic properties (colors and materials). Our study shows that the most inherited product categories are kitchenware (24%), furniture (21%), home decoration (14%) and jewelry (12%); it also shows that the reasons for keeping inherited products differ across product categories. However, inherited products commonly display honest and/or gracefully aging material, colors that reflect the material choice, single functions, and functional independency—that is, they do not rely on other products to function.
