With mortise and tenon structure furniture as the design carrier, the cultural connotation of traditional symbols is absorbed and new ideas for the inheritance and development of traditional culture in modern life are explored. Starting from the analysis of the modeling characteristics, decorative characteristics, and allegorical connotations of the swastika, its feature elements is summarized, the keywords of the design elements are screened, applications and extensions on this basis are designed, the basic model of furniture products is established, then the tenon and tenon forms that meet the strength requirements and material requirements according to the model are screened, the overall construction of tenon and tenon structure furniture products is completed, and the physical production of the products is guided. Combining the swastika form with the tenon structure bookcase design, the traditional symbolic feature elements are effectively integrated into the design of the tenon structure furniture, which verifies the feasibility and effectiveness of the method and provides a reference for the design research of related tenon and tenon products.
