Driven by the fast evolution of artificial intelligence and the upgrading of the art and design industry, the conventional teaching model of art design is in urgent need of restructuring. The integrated development of human, “Human-AI-Scenario” has become the core orientation for the innovation of intelligent teaching in art design. This paper explores the essential connotation of the tri-element integration in intelligent teaching, clarifies its value in reshaping teaching logic, cultivating interdisciplinary talents and promoting disciplinary development, and puts forward three systematic innovation strategies: personalized teaching empowerment, optimized teaching implementation and evaluation, and the construction of an industry-education integration platform. With specific teaching cases, this study elaborates the practical paths of each strategy. The results show that the tri-element integration model effectively addresses the drawbacks of traditional teaching, improves teaching quality, and nurtures interdisciplinary art design talents who meet industrial demands.
