Abstract: Integrating traditional architectural elements into contemporary jewelry design serves as a vital pathway for inheriting and revitalizing cultural heritage. However, current practices often remain at a superficial level of imitating decorative symbols, lacking in-depth translation of core architectural structures and a systematic methodology for cross-scale transformation. Focusing on the Giant Wild Goose Pagoda, a paradigm of Tang Dynasty architecture, this study aims to explore innovative translation pathways from its architectural elements to contemporary jewelry design and to establish a theoretical framework for such cross-scale design transformation. Combining theoretical analysis with design practice, this study first employs topological analysis to deconstruct the geometric composition and mechanical logic of the pagoda's beam-column and dougong structure(a traditional Chinese bracket set), while utilizing semiotics to analyze their cultural connotations and spatial aesthetics. Based on this, a multi-dimensional mapping model between architecture and jewelry is constructed, encompassing 3 dimensions: structural topology, semiotic semantics, and phenomenological experience. Through a series of jewelry design practices, this study transforms the structural features of the Giant Wild Goose Pagoda—such as mortise-and-tenon joints, the projecting tiers of dougong structure, and layered rhythm—into micro-load-bearing frames, modular components, and spatial narratives in jewelry. This structure-based translation approach not only enhances the cultural depth and expressive capacity of jewelry but also promotes a paradigm shift in craftsmanship from decorative to constructive expression. This study provides a systematic theoretical framework and practical references for the innovative inheritance of traditional architectural culture in contemporary design contexts.
