Research on Interactive Design of Intangible Heritage APP Based on CA/QFD/TRIZ Integration Method

Abstract

This study addresses challenges in intangible cultural heritage (ICH) development under cultural digitalization strategies by optimizing ICH app design using an integrated CA/QFD/TRIZ approach. User needs were identified through CA analysis of app feedback, utilizing ROST CM6 software for word frequency and social semantic network analysis to categorize primary and secondary demand categories. These needs were translated into product features using QFD theory, which also identified key contradictions. TRIZ theory was then applied to resolve these contradictions and generate solutions. Based on this process, specific ICH app design strategies were formulated and validated through a case study, resulting in a comprehensive design solution. The integrated CA/QFD/TRIZ paradigm quantitatively clarified user needs, optimized design directions, and provides a valuable framework for future app design research, empowering the digital transformation of traditional ICH.
