Creative reasoning is an important part of product creative design. To help designers clarify their reasoning thinking in the design process, this paper proposes a manual craft product creative design reasoning model based on traditional animal pattern cultural elements. This model combines the form, color, and semantics of traditional animal patterns with traditional intangible cultural heritage and uses semantic reasoning to assist creative design. The cultural elements in animal patterns are combined with modern products and objects, personalized requirements, and scenarios to generate random sentences, which helps designers in creative design reasoning. This model can effectively guide designers to integrate cultural elements into creative design, provide ideas and practical methods for the inheritance and innovation of traditional patterns and handicrafts, and improve the cultural connotation and market competitiveness of handmade products.
