面向计算机的产品创新设计新模型与新原理(II)

New Models and Principles on Computer-Oriented Innovative and Creative Design of Products(II)

该文基于物元动态系统理论提出了产品虚实模型、产品潜显模型、产品正负模型等产品创新设计模型,分析了产品的同素多构性、一关系多实体性、同构多素性、虚实统一性、一显多潜性、一正多负性等性质。给出在一定的条件下,异构同功,异素同功、同潜产品同功,以及同正产品可互相转化产品、同负产品可互相转化的产品创新设计新原理。新模型和新原理有利于开发计算机辅助产品创新设计系统CAPCDS。

Matter element system model of products,soft-hard model of products and structure model of products are given,which are propitious to representation in computer.This paper deeply analyzes multi-function property of product,a characteristic with multi-product and a value with multi-product by matter element system model of products.The inno-vative and creative principlesa such as″the products with same matter element have same function under certain condi-tions″,″the products with same characteristics have same function under certain conditions″,″the products with same val-ues have same function under certain conditions″are proposed.Moreover the paper studies function decomposition of products,functional relation between function and components of production,and functional relation between function and structure of product.The new models and principles are good base for development of intelligent CAD which can sup-port innovative and creative design of products.
