This study, based on TRIZ theory, explored the design and manufacturing process of wooden low stools. The results showed that the systematic approach and innovative tools provided by TRIZ theory effectively resolved various contradictions encountered in the design of wooden low stools, thereby enhancing the product's performance, aesthetics, functionality, and competitiveness. Through the appropriate application of TRIZ, product design and manufacturing were optimized, providing a reference for promoting the upgrading and transformation of the entire wooden furniture industry. This study offered TRIZ theory as a thought process for product design research and provided a reference for the wood industry and woodworking workshops.
