Abstract: An innovative solving model based on the interaction of design flow and knowledge flow was proposed in order to rationally organize the design process and effectively utilize design knowledge during the stage of conceptual design, and to encourage designers to produce creative design scheme. Based on the different features and different supporting functions of various design factors, such as function, behavior, and structure, design flow oriented to diversified design, adaptive design and original design was established. Knowledge flow including function knowledge, behavior knowledge, and structure knowledge was established based on the design flow. Different goals of design were realized by the multi-level reciprocating mapping under the interactions of design flow and knowledge flow. Corresponding function modules were developed based on the Innovative Design Service Platform developed by the research group. An innovative design process of a coffee machine was completed to verify the validity of the model.

Key words: innovative design, design flow, knowledge flow, solving model, product design
