The work aims to explore the mechanism and pathway of creative service design patterns for intelligent interactive products in the digital age. This paper elaborated on the connotation and characteristics of the creative service industry era, summarized the creative service requirements for intelligent interactive products in the digital age, and analyzed innovative strategies for creative service design patterns from three perspectives:product quality innovation requirements, innovation performance improvement requirements, and path optimization requirements of economic value transformation. A three-stage creative service design model of "multi-faceted design big data innovation - optimization of intelligent generative design tools - reconstruction of stakeholder collaborative design platform" was proposed and analyzed with case studies. The innovation of data resources for creative service design, intelligent optimization of design tools, and reconstruction of collaborative innovation value chains could effectively improve the quality and quantity of intelligent interactive product design outputs, optimize the design iteration cycle, and achieve a two-way improvement in product value innovation performance and economic value driven by design. Through the digital intelligent integration and reconstruction of knowledge productivity elements, an intelligent aided design tool system integrating the whole chain of design elements is constructed to enhance the innovation ability of designers, which can bring strong and sustainable innovation and design power to enhance social and economic value.
