Abstract: The phoenix pattern from the Western Zhou Dynasty contains rich cultural symbols and represents the profound historical heritage and unique national wisdom of Chinese nation. This study first explored the historical origins and design elements of the phoenix pattern and analyzed its characteristics and cultural implications. Based on this understanding, a consumer demand survey was conducted to define the design positioning and initiate design research. Using shape grammar theory, initial pattern extraction was performed, followed by derivative pattern design through the parametric design software Rhino and Grasshopper plugin. By adjusting parameter control points, design schemes were generated that align with contemporary aesthetic demands. Taking into account consumer demand findings, this study then examined how these derived patterns can be applied in the design of leather bags. This design aims to satisfy modern aesthetic preferences while reflecting the ethnic characteristics and cultural depth of the phoenix motif. The parametric design approach applied to the phoenix pattern can enhance the efficiency of generating derivative patterns and provide valuable insights for the innovative design of leather goods.
