Abstract: To find optimal balance between physical products and intangible service, the evolution roads to product service system based on TRIZ final ideal solutions were provided from functional perspective. Then, the function model of the product service systems was constructed based on service blueprint and functional system diagraphs. On this basis, a new product service system innovative design method was proposed by applying function stimulations such as function collaboration, function supplement, and function displacement. By defining concept solution and scheme according to the results of function stimulations, the final product improved solution was generated. Finally, the product service system design process of agricultural machinery based on computer aided innovation product (CAIP) was analyzed to verify this method.
