Product appearance sensory evaluation model using Qualia Theory and AHP for Chaozhou woodcarving crafts

This study proposes an integrated operational framework fusing Qualia Theory and the Analytic Hierarchy Process (AHP) to address subjective ambiguities in modernizing Chaozhou woodcarving crafts. Leveraging multi-source data-including 9784 scraped e-commerce reviews (2699 validated samples), expert interviews, and user questionnaires-we identified a five-dimensional criterion layer (Delicacy, Engineering, Creativity, Charm, Aesthetic Appeal) with 15 sub-indicators. AHP-derived weights (CR < 0.1) prioritized Craftsmanship Delicacy (0.320) and Engineering Integrity (0.250) as dominant dimensions, with "knife-work refinement" (global weight: 0.150) and "structural robustness" (0.130) as critical design parameters. Notably, Aesthetic Appeal (0.090) held the lowest weight, revealing a user preference for technical mastery over pure form. Guided by these weights, a parameter-driven 3D modeling process informed three thematic lighting prototypes. Empirical evaluation via fuzzy comprehensive evaluation demonstrated progressive satisfaction scores (Scheme "a": 77.72; "b": 79.30; "c": 80.52), suggesting the framework's effectiveness in translating subjective perceptions into objective design optimization. This work provides a replicable, data-driven paradigm for the evidence-based modernization of intangible cultural heritage.
