基于形状文法的泛族群产品形态设计

Pan-ethnic-group product form design based on shape grammar

为继承消费者对现有产品的意象感知,塑造差异化的产品形态,引入人类学及心理学基本理论,建立泛族群产品的理论模型。提出将目标产品泛化为同族群产品与异族群产品,从中提取能够反映消费者感性需求的形态要素,与目标产品形态融合并应用形状文法进行形态方案推理。探讨了形状文法的理论模型及推理规则,在形态推演过程中引入尺寸及推理次数约束,构建了形态推演算法;研究了泛族群产品的形态设计过程。以电动滑板车的形态设计为例,对其形态进行分解,分析并抽取了同族群及异族群产品形态元素,构建了形状文法推演引擎。通过实验对比,验证了方法的有效性。

To inherit customers＇ affective responses of current product and to build differential product form,a theoretical model of pan-ethnic-group product was built based on anthropology and psychology.Target product was generalized as domestic ethnic group product and foreign ethnic group product.Form elements of pan-ethnic-group product that could reflect customers＇ affective needs were extracted and integrated with target product form to generate new schemes with shape grammar.The theoretical model and inference rules were discussed.In product form inference process,the inference algorithm was constructed by introducing constraints of target product dimensions and inference times.Moreover,the process of pan-ethnic-group product form design was researched.The electric scooter was taken as an example to decompose its form,and the form elements of both domestic ethnic group and foreign ethnic group were analyzed and extracted.Based on these,an inference engine of shape grammar was constructed to generate new product form automatically.By experimental comparison,the effectiveness of method was proved.
