树结构与实例结合的形态创新设计方法

Case and Tree Structure Based Product Creative Design Method

采用树结构和实例结合构建产品结构树模型,并以树的不完全分解进行包含形态特征的语义综合推理,从而对实例的组合进行导向及控制,探索了构造实用的形态创新设计系统的一种可能途径。并在Alias造型平台上二次开发实现了一个包含实例基元库及其它设计资源库的首饰形态创新设计系统。初步应用表明,系统在快速设计和引导设计等方面有较好的支持,提高了设计效率。

In the paper, a product shape tree model is defined based on tree structure and design case.An incomplete decomposing method is presented to guide the case searching over the shape tree model. In order to determine the proper case and acceptable case combination, semantic reasoning is derived from shape features. And based on Alias modeling platform, a creative design system and its design meta-case database are developed to supporting jewelry design. It is shown that the method can enhance design system effectively by giving some basic design schemes and guide designers to archive their aims rapidly.
