With Weifang kites as the research object, the work aims to explore the process and methods of cultural and creative product design, as well as the design transformation strategy, to provide theoretical exploration and empirical research for improving the cultural communication effect of cultural and creative products. Based on the theoretical basis of Peircean semiotics, the theories of ternary communication, trichotomy and ternary composition were introduced into the design process of cultural and creative products. The design points of the three dimensions of "establishment of internal logic", "transformation of symbolic meaning" and "circular interactive communication" were specifically analyzed to construct the semiotic expression model of Weifang kite cultural and creative product design, and the model was tested through design practice. The cultural communication advantages of Peircean semiotics applied to the design of Weifang kite cultural and creative products are demonstrated. The information communication process of cultural and creative products is interpreted from the perspective of trichotomy, focusing on the effectiveness of cultural communication. The formal characteristics and cultural connotations of translated cultural symbols are extracted from the perspective of trichotomy, giving the product the core cultural value. The product coding is guided from the perspective of trichotomy, thereby guiding users' multiple needs such as interpretation and cognition of Weifang kite culture, and realizing the circular communication of cultural information.
