This study aims to propose an innovative jewelry design method that combines knowledge graph with artificial intelligence to solve the problem of relying on the experience of designers in the traditional jewelry design field, resulting in unstable design quality, difficulty in inheriting experience, and inability to evaluate innovation. The specific method is to extract research hotspots in jewelry design from the knowledge graph, and construct artificial intelligence recognizable prompt words based on the rules of prompt word formation. Use prompt words in artificial intelligence tools to generate ideas, then use AHP Analytic Hierarchy Process to screen the best ideas, and finally combine the designer’s ability to output design solutions. The combination of knowledge graph and artificial intelligence can affect the working methods and efficiency in the field of jewelry design, improve design quality and innovation, and solve the problem of inheriting design experience, which is of great significance for modern jewelry design.
