The digitalization of museums offers new opportunities for presenting and interpreting cultural artifacts, yet visitor engagement and perceived value often remain limited due to low interactivity and insufficient experiential design. To address these challenges, this study proposes the THEB model, a four-dimensional framework for enhancing cultural relic value perception across Thing, Human, Emotion, and Beauty dimensions. The model was applied to a case study of the Rhinoceros-shaped Bronze Zun Inlaid with Gold and Silver Cloud Design. Guided by the THEB framework, AI-generated images and a narrative video were produced using tools such as Midjourney and Pixverse AI. A controlled user study with 230 participants compared the AI-generated video to traditional museum content. Results indicate that while historical depth was not significantly enhanced, the AI video substantially improved engagement, satisfaction, and immersion, particularly in aesthetic appreciation and emotional resonance. These findings validate the THEB model as a practical and conceptual tool, demonstrating its potential to guide museum exhibition design toward more holistic, emotionally engaging, and interactive experiences, bridging material, humanistic, and aesthetic dimensions of cultural heritage.

Product design methods based on case-based reasoning (CBR) generally lack sufficient consideration of customer opinions. To address this problem, a user satisfaction-oriented CBR method for product conceptual design is proposed. The method consists of three stages. First, a quantitative mapping relationship between design cases and user satisfaction is established, and a case base is constructed. Subsequently, new product structural solutions are generated by adopting case reuse or innovative design approaches. Finally, a multi-objective decision-making model incorporating multi-dimensional factors is established to solve for the optimal conceptual design scheme. A conceptual design project for a tablet computer demonstrates that the proposed method effectively enhances user satisfaction with design schemes. This method provides a new perspective for the research of case-based product design methods and is of great value for improving the design symmetry between the conceptual design scheme and user requirements, and thereby enhancing the quality of enterprise product conceptual design.
