This study establishes a novel Bio-Cultural Heritage Design Framework that integrates grounded theory and biomechanics to address the sustainable development of traditional crafts in the digital era. Using Chaozhou woodcarving as a case study, we constructed a hierarchical demand system through a three-stage coding analysis of 1,250 online reviews, 381 survey responses, and expert interviews, identifying biomechanical utility (A1, 40% weight) as the dominant factor. Key sub-criteria—ergonomic compatibility (C12, 0.21 weight), material durability (e.g., nanmu wood with elastic modulus ≥8 GPa), and structural stability (C22, 0.15 weight)—were translated into AI design constraints via Analytic Hierarchy Process (AHP). AI-generated prototypes (e.g., Sample 15, score 4.53/5) demonstrated superior biomechanical performance, validated by finite element analysis (stress distribution本研究构建了一套全新的生物文化遗产设计框架（Bio-Cultural Heritage Design Framework），整合扎根理论与生物力学，以解决数字时代传统手工艺的可持续发展难题。本研究以潮州木雕（Chaozhou woodcarving）为案例对象，通过对1250条在线评论、381份调查问卷及专家访谈开展三阶段编码分析，构建了层级化需求体系，并确定生物力学效用（A1，权重占比40%）为核心影响因素。核心子准则包括人机工程适配性（C12，权重0.21）、材料耐久性（如弹性模量≥8 GPa的楠木）与结构稳定性（C22，权重0.15），通过层次分析法（Analytic Hierarchy Process，AHP）将其转化为AI设计约束条件。AI生成的原型（例如样本15，得分4.53/5）展现出更优异的生物力学性能，经有限元分析（finite element analysis，应力分布）验证。
