Abstract: A generic functional model based on feature is proposed.
The genetic information foundation of principle conceptual design—
“product gene” is proposed after a systematic study of the similarities
between principle conceptual design and genetic engineering. Product
gene’s working mechanisms of “transcription”, “translation”, “copy” and
“reverse transcription” are also proposed, which disclose that product
gene is a bridge across functional design and principle conceptual
design. Referring to genetic engineering, a new methodology of
conceptual design based on the inheritance and reorganization of product
genes is proposed. The conceptual design of a new mechanical device for
separating coins is given as an example, which demonstrates that the
methodology is obviously helpful for product principle innovation in
conceptual design.
Key words: Conceptual design Design methodology Genetic engineering
