In product service systems (PSS) design and with sustainable development needs, conflicts usually emerge due toa major reason of requiring high-lever component functions, which could simultaneously add complexity to asystem. However, there is no research found that provides a well-structured methodology for eliminating identifiedcontradictions in PSS design. To narrow this gap, this study proposes a systematic PSS design approach based on theTRIZ methodology for generating systematic solutions. A research-based design case enacted the proposed method toshow its feasibility. In this context, a design team was formed for the PPS system design regarding online/offline shoppingservice systems with fresh flower products based on marketing needs, such as customers, the flower industry, and the ecommerce environment. The results demonstrated that the proposed approach is feasible and effective in innovationservice, with the case study, while aiding the design team in creating PSS products and services. The identifiedcontradictions were tackled in the design process, which generated intensive resolutions for the PPS systems. Finally, thestudy discussed the features of the PSS design compared with the previous study regarding another PSS model of sharingbikes, and summarized the facilitations with various techniques, e.g., a service blueprint for the online/offline shoppingjourney.
