Abstract: High-level
solutions of product innovation are gained using the contradiction
concept of theory of inventive problems solving (TRIZ). From the basic
ideas of TRIZ, five constructions of design problems are ulteriorly
expounded. Point problems (physical contradictions) are mainly studied,
and are classified three forms from time and space region.
Representation model of physical contradictions is developed. The
numbers of heuristics principles application of solving physical
contradictions are added. Based on this principle, a conceptual design
model of product is developed, and the design process is realized with
software programming. Using an engineering case shows the application of
the process.
