产品胚胎仿生设计模式
首发时间:2005-12-23
摘要:本文借鉴胚胎发育学提出设计早期阶段产品胚胎组织结构形成的4种模式,用生物学术语表达为:1 细胞决定;2基因转录;3分化诱导;4 转决定。设计过程中4种模式循环共同作用决定最终产品结构。细胞决定在设计的不同阶段发生以确定下一个阶段结构的发展方向,在设计早期阶段主要是对产品功能的限定和约束。基因转录贯穿于整个设计过程,正如细胞分化过程中基因的开启表达有序进行,子结构分化过程中基因顺序关闭和开启从而限制子结构的发育方向,直至子结构分化过程受到分化抑制作用而终止。分化诱导是设计过程中的主导模式,从功能到专能机构是子结构从全能到多能到专能的发育过程,这个过程通过子结构分化实现,子结构分化方向是基因选择性表达的结果,子结构互相作用,通过相互联系变量发生诱导作用,导致新的子结构产生。转决定是创造性设计的必要模式,子结构的分化潜能具有遗传稳定性,因此创造性设计必须改变基因中的某段,即转决定发生。

Bionic developing modes of product embryo
Abstract:This paper proposes 4 bionic developing modes for early stage of design by analogy with embryogenesis. The 4 modes are commitment, gene transcription, induction, and transdetermination in term of biology and they cooperate to guide the development of future product. Commitment is to determine the development of next stages and it occurs regularly during design process, which means to specify the product functions and constraints in the early stage of design. In the development process, gene transcription occurs to guide cell differentiation and some parts of gene switch on or off to direct and confine the development directions of structure. As cells differentiate into specialized cells through embryonic induction in the development of natural life, simple function structures differentiate into specialized structures resulted from connection property induction and generate new structures, which process is a dominant developing mode and governed by induction rules that are triggered by gene selective representation. The direction of cell differentiation may change when transdetermination occurs, therefore one approach for creative design is to change the switching sequence of gene and the other approach is to add or to cut variables.
Keywords: bionic design, commitment, gene transcription, induction, transdetermination
