Construction of Double UG Design Model of Product Service System from the Perspective of Media Participation

As a new production system that highly integrates tangible products and intangible services, the product service system provides an opportunity for the transformation from discrete production to integrated production. Product Service System Design, proposed on this basis, involves systematic planning and design of related strategies, concepts, products, usage, processes, etc. However, existing literature shows a relative lack of attention on the role of “Media” during product service system design. Hence, this study, grounded in Product Service System design procedures and Uses & Gratifications theory, constructed the Double UG Design Model encompassing four phases - Unearth, Generation, Uses & Gratifications - with reference to the Double Diamond Design Model. The model emphasizes the working mechanism of “Media” across the entire design process, explores more possibilities brought by interdisciplinary research, provides new ideas to subsequent studies on Product Service System Design, and expands the application boundary of media in design research.
