Building And Applying Of Creative Design Process Model Based On Cognition Of Product Sign

Symbolic consumption has been a new current,therefore, the focus of users'cognition to innovative product has transferred from using of applied function to constructing of symbolic meanings and experiencing of aesthetic feelings. Based on this context, the purpose of this research is to construct creative product design process models and applied methods based on systematic analysis of product sign and its cognitive characters, these design process models and methods are oriented with comprehensive interaction between user and product sign.Combining with systematic theories of semiotics and product, this research explored the physical attribute, intentional attribute, temporal attribute and spatial attribute of product sign. Then, outlined the expanded communication process of product sign meaning, such as'industrial designer→sketches→engineering drawing→product→commodity→appliance→user's apperceive→user's response'. Based on these, this research outlined the macro communication manner and the micro communication manner between user and product sign.Importing the theories of cognitive psychology and aesthetics, this research explored three kinds of users'cognitive responses to product sign, such as aesthetics impression, semantic interpretation and symbolic association. Moreover, this research analyzed five kinds of influences—context, literacy of use, mental models of product, population stereotype and conditions of sue, to these cognitive responses. Then, this research exposited the interactive manners among aesthetic impression, semantic interpretation and symbolic association, and the relations between cognitive response, affective response and behavioral response. The results suggest that cognition dominate affection, affection influence cognition, cognition alternate behavior.Orienting by interactive multi-relations of'user-product sign', basing on Gero's FBS framework, this research constructed a basic creative product design process based on product sign recognition-PFBCS model, by importing a new design variable-Cognition. Mover, this research outlined the expended PFBCS framework, and offered three kind design processes of PFBCS model, such as PFBS, PFCS and PFBCS. Then, by statistic analyzing of creative designs awarded Red Dot Design Concept 2009, this research suggest that the awarded works creating from the perspective of cognition cover 34.1% of the total awarded living good designs.Based on the expended PFBCS framework, this research offered a creative design method driven by cognitive emergence and unexpected discoveries of sketches. Then, based on the interactive relations of'user-product sign', this research constructed the basic semantic network model of product case-sign cognition, and offered the basic creative design method driven by spreading of this semantic network model. Moreover, from the transforming perspective of temporal attribute and spatial attribute, this research offered a creative design method driven by spreading of semantic network model through behavior process subdividing, and a creative design method driven by spreading of semantic network model through usage scenarios analogying. Then, by two creative design experiments and statistic analysis of creating sketch-schemes, this research suggests that semantic network model of product case-sign cognition is very useful for designers to quickly create designs from multi-perspectives, and these designs can accord with the expected purpose.
