Abstract
<jats:p>Aiming at the problems of cultural distortion and inefficiency in intangible cultural heritage (ICH)-themed home product design, this paper proposes a closed-loop optimization method for home product design. The hierarchical cultural needs and judgment matrix from the Analytic Hierarchy Process (AHP) stage are converted into weight parameters for AI-Generated Content (AIGC). A comprehensive evaluation model is then constructed using Fuzzy Comprehensive Evaluation (FCE) theory to assess the cultural adaptability and design feasibility of AIGC-generated home product schemes, forming an iterative improvement process. The AIGC schemes from the experimental group significantly outperformed the baseline group in terms of cultural core feature compliance, functional adaptability, and production feasibility. This confirms that the proposed model can effectively address the core issues in ICH home design, such as cultural distortion, functional imbalance, and difficulty in production implementation. It provides a reliable technical pathway for the modern design transformation of ICH elements.</jats:p>
