Abstract
In the context of rising market competition, diverse customer needs, and increasing environmental concerns, product-service systems (PSS) are gaining attention for achieving financial benefits and resource efficiency. Existing research on PSS design has applied multi-objective optimization methods to derive solutions that meet the requirements of multiple stakeholders. However, when strict constraints exist among PSS design requirements and their realization, simple optimization often fails to satisfy all stakeholders. To address this, the paper focuses on the inventive design approach, which facilitates creative solutions for problems that are difficult to solve through optimization. This paper proposes a method to support optimal design of PSS by integrating TRIZ, an inventive design approach. The proposed method is demonstrated in a PSS design case for automated valet parking. Application results show the method enables designers to resolve physical contradictions using a comprehensive, top-down design approach.
