Abstract: Based on the fact that appending and solving auxiliary
functions are always depended on solving the aim function during
conceptual design phase for complex function, the conceptual design
cyclic mapping model which supports cyclic solving between function
layer, effect layer, principle layer and structure layer is put forward.
It consists of three mapping pattern and twelve mapping relations, such
as decomposing mapping, solving mapping and deriving mapping. Then the
key techologies such as of interface expression and mapping and function
reasoning are discussed. Finally a computer aided conceptual design
automatic software system is developed and the conceptual design of
coinassorter is given as an example.
Key words: Complex function solving Cyclic mapping Interface
mapping Function prototype
