Research On The Entropy Evaluation Of Product Styling Image

The product modeling image was formed in the man’s cognitive processes of product modeling. To grasp the man’s evaluation laws of product modeling images would have a good theoretica l and practica l reference value for desig n and deve lopme nt. In the process of product modeling image eva luat ion, people, such as users, designers, engineers and so on, who acknow ledged the product modeling ima ges according to the ir own cognit ive model would lead to a different cognit ive. Aimed at the cognit ive differences in product styling image, a new eva luat ion met hod was presented us ing t he entropy theory. Then t he cognit ive differences between users, designers and engineers were ana lyzed through t hree image cognit ive spaces which were built for the m. Then, a typ ical database, personality a nd plat form des ign elements were obtained to effectivel y guide product styling design.In this research, the process of product mode ling image eva luat io n was mapped to the chaotic state. Based on t he theory a nd method of entropy, t he image o f product modeling and design ele ments were eva luated. The ma in contents inc luded fo llow ing three parts.First ly, the whole process and technical methods were stud ied to determine the research samp les and the product target ima ges. Taking the water bottle styling as an examp le, 20 research samp les and 3 target images were determined us ing this process.Secondly, a method of t he entropy eva luat io n of product modeling image under the cognit ive differences between users, designers and engineers was founded after the ir cognit ive models were invest igated. First o f all, t hree ima ge cognit ive spaces were built for users, designers and engineers, and the cognit ive d ifferences between the m were analyzed. The n, a compos ite image cognit ive space based on the ir emot iona l require ments was constructed in view of cognit ive weights. Fina lly, taking the co mposite ima ge cognit ive space as core, an evaluat ion model of product styling ima ge was presented based on entro py theory, whic h could guide the selectio n of representative product samples.Third ly, in order to explore the link ing between the emot iona l demands of cognit ive groups and the design e le ments of product modeling, an eva luat io n way of product design e le ments was set up. At first, the research samp les were deconstructed. Next, the coupling and the attr ibute of game between product and des ign ele ments as well as design e le me nts and design e le ments were parsed by t he entropy t heory. Last, the persona lity des ign e le ments and the p lat form design ele me nts were ident ified by measur ing t he ir mut ua l infor mat ion coeffic ient, w hich could guide the subsequent product design.The representat ive product samp les and the know ledge base of product design ele ments were comb ined to guide product styling design, meanw hile, it a lso could deve lop design ideas in the process of product modeling des ign. Thus, a product modeling was finis hed which me t t he e mot iona l needs of users, designers and engineers.
