In the new format of the current digital economy, consumers' demand for personalized customization of cultural and creative products is gradually being released. Meanwhile, the successful application of Liangzhu Civilization for world cultural heritage status indicates that it urgently needs further innovative development and creative transformation. However, the Liangzhu cultural and creative industry has not fully exploited its cultural potential. Combining AIGC technology to build a personalized customization system for cultural and creative products can contribute to the inheritance and development of Liangzhu culture. With the personalized customization of Liangzhu cultural and creative products as the research carrier, this paper explores the design method of embedding digital and intelligent technology into the personalized customization system. Through relevant research and case analysis, it clarifies functional requirements, overall composition structure, development process, and key technical means of the system. This paper proposes an "8"-shaped double helix innovative design chain under the background of digital intelligence, coupling the cultural context, the artificial intelligence context, and the human-computer collaboration context, to promote the personalized customization of cultural and creative products towards a more precise, diverse, and efficient direction, providing a reference for the coordinated development and digital transformation and upgrading of the cultural tourism industry.
