Abstract: This paper proposes an integrated method for innovative product-service system (PSS) design based on the theory of inventive problem solving (TRIZ) methodology. Extant TRIZ-based approaches for PSS innovation are largely based on a single mode of solution development. They are limited to deal with only technical-contradiction problems either through direct use of the adapted inventive principles or by applying the contradiction matrix to solve conflicts with some simplified rules. By integrating multiple TRIZ tools, the proposed new method is capable of providing three different search routes and their combinations for generating innovative product-service solution concepts. In comparison with other similar TRIZ-based approaches, this method is more flexible and effective in solving problems of different natures, i.e., technical contradictions, physical contradictions, and non-contradictions, as well as their mixes. A real-life case study on a datacentre PSS design is presented at the end of this paper to illustrate the application of the new method.
