Study on design of Linxia brick carving products based on shape grammar

In view of the problems such as the single type of cultural derivative products of Linxia brick carving and the weak cultural attraction, we carried out the application research of Linxia brick carving culture by using shape grammar. Firstly, we collected and combed the materials of brick carving culture in Linxia by means of literature research and field investigation. Then, we determined the target product, analyzed the product form and emotional demand, construct the reference product form database, screen the brick carving pattern through the matching of the product emotional demand, obtained the characteristic lines of the brick carving pattern by the way of the type spectrum analysis, and established the typical form factor database of brick carving; Finally, taking some lines in the typical form factor database as the initial shape, we combined them with the lines in the reference product form database. According to the shape grammar deduction rules, the scheme was generated, the best scheme was selected and further refined. Studies have shown that the use of shape grammar for product design can enhance the cultural connotation of products, promote cultural heritage, and effectively guide the design of Linxia brick carving products.
