Abstract: In order to deal with and represent the numerous design information from the generation of conceptual solution, hierarchical model of design features was constructed to represent the abstract topology of conceptual design product. Then an attribute-dependence relationship network model was presented. Based on these two models, a relationship network was set up to represent conceptual products design information. Subsequently, main ideas of polychromatic sets were introduced. Therefore the mathematic description of conceptual product based on polychromatic sets was constructed with elements of conceptual solution design information corresponding to the components of polychromatic sets. This representation was convenient for the storage, the management of the product design information and the subsequent design work.

Key words: conceptual design, design information, design attribute, design feature, polychromatic sets
