FBS模型中行为与结构创新的商空间表达与实现

Implementation and Quotient Representation of Creativity in Functional Layer and Form Layer of the Function-behavior-structure Model

提出一种能够支持专利技术再创新的方法,对于提升我国机电产品的快速创新开发能力具有重要的现实意义。考虑基本结构的多功能属性,用粒度更细的基本操作表达功能—行为—结构(Function-behavior-structure,FBS)模型的功能元和基本结构的行为,以商空间理论作为数学工具,建立创新增强型FBS功能分解与结构匹配的商空间模型。功能层的保序划分或分层递阶划分实现了行为层创新;基于等价关系的结构层划分实现了结构层创新。实例表明,通过结构层和功能层的创新、匹配,能够用较少的简单基本结构的组合匹配原设计问题的总功能。因此,该方法可以有效地支持专利技术的再创新设计。

Presenting a method to support the re-creative design of patented products is important for enhancing the ability for enterprises to develop innovative products rapidly. Considering the multiple functions for each basic structure to have and expressing each function in function-behavior-structure （FBS） model with basic operating actions, the creativity enhanced FBS function decomposition and structure matching model is set up with the aid of the quotient space theory. The sequence-keep partition and hierarchical partition have made the behavior creativity to realize in the behavior layer, the form layer partition based on the equivalence relation has made the structure creativity to produce in the form layer. The case study based on creativity enhanced FBS model shows that the general function of the patented products can be realized by simpler and fewer basic structures. It means that the model can efficiently support the re-creative design of patented products.
