The work aims to explore the inheritance and development of Shenmu Shimao culture in modern society and break and reconstruct the representative cultural elements excavated, interpreted and extracted from cultural relics into new utensil shapes and then apply them to cultural and creative products to promote the diversification of cultural and creative product design ideas in the market. Based on the deduction rules of shape grammar, the cross-integration with the modeling of modern tea set was made according to the modeling characteristics of Shimao pottery, jade modeling and Shimao stone carving patterns. Combined with the innovative design concepts, the design was conducted. The teapot, tea cup, justice cup and tea plate were taken as the combination of Shimao tea set to conduct the shape design deduction. The cultural and creative product design of Shimao tea set with Shimao modeling style and in line with modern aesthetics was obtained. The practicality and effectiveness of the case method are verified through practice, which provides theoretical guidance for the innovative design of Shimao modeling and pattern, as well as its transformation into modern products and integration into modern life. In the meantime, a new way is provided for protecting Shimao site culture.
