苗族背扇作为贵州地区重要的非遗载体,承载母爱寄托、族群记忆与礼物伦理,其情感价值与文化寓意构成“温度型非遗”的典型表征。在智能技术快速演进背景下,探索在不削弱手工技艺主体性的前提下,实现非遗产品当代转化与活态传承的设计路径。基于背扇文化符号系统与情感传递链分析,结合情感化设计三层次模型,采用田野调研与感性工学对用户情感印象与设计要素进行量化映射;进一步融合生成式人工智能的多模态理解与判别式分析思路,构建“识别-生成-评估-优化”的人机协同创新框架。以“智能背扇系统”为设计载体,形成涵盖概念生成、纹样与外观、结构与硬件、软件与交互的一体化方法流程,并提炼出可复用的设计要点与评价维度。提出“情感-文化-技术”三维共生的非遗创新设计模型,为同类具有情感温度的非遗产品当代转化提供可迁移的方法参考。

The Miao back fan, a key intangible cultural heritage (ICH） artifact in Guizhou, embodies maternal affection, collective memory, and gift ethics. Its affective value and cultural implications typify "warmth-oriented ICH". Against the backdrop of rapidly evolving intelligent technologies, the work aims to explore a design pathway for the contemporary transformation and living inheritance of ICH products without undermining the agency of traditional craftsmanship. Based on the back fan's cultural semiotic system and emotional transmission chain, and combined with the three-level model of emotional design, field investigation and Kansei engineering are employed to quantitatively map users' affective impressions to design elements. Building on multimodal capabilities of generative artificial intelligence and a discriminative analytical approach, a human-AI collaborative innovation framework of "recognition-generation-evaluation-optimization" is constructed. An "intelligent back fan system" is presented as the design vehicle, yielding an integrated workflow spanning concept generation, patterns and appearance, structure and hardware, and software and interaction, along with reusable design guidelines and evaluation dimensions. The resulting "emotion-culture-technology" symbiotic model offers a transferable methodological reference for the contemporary transformation of similarly warmth-infused ICH products.
