Abstract:
On the
basis of Axiomatic design (AD) theory, several key techniques for
generating conceptual design schemes of mechanical products are studied.
Customer – driven issue of conceptual design is discussed. It proposes a
strategy for establishing the mapping from customer domain to functional
domain. The concept of Domains Structure Template which is directed
against the defects of AD is proposed to extend AD, and concept space
and concept reasoning network are constructed. Effective Concept Space
is filtered out by restraint reasoning from concept reasoning network,
and effective concept space resolving algorithm is symbolically
described. The functional relationships between design entities involved
in individual scheme are analyzed based on conceptual graphs. A high
speed chainstitch sewing machine is used as a case study to show the
effectiveness of the proposed method and associated algorithms.
Key words:
