| Currently, the market of consumer elcectronics products(abbreviation as "Products") is fiercely competitive increasingly, while the customer needs in diversity and personality for products are gradually deepened. Improving the customer satisfaction of company products is an effective way to resolve the difficulty in this context. Conceptual design is the most creative stage in product innovation process, it determines the basic features and the design solutions of products. Therefore, it is the key to improve the customer satisfaction for company that access to customer needs efficietly and accuratly and generate the solution to product conceptual design in line with customer preferences. Meanwhile, there is much practice significance to research the generation of product conceptual design solutions based on the idetification of customer needs and preferences for improving the customer satisfaction and enhance the competitiveness of company. This thesis takes product conceptual design process as the mainline, takes customer needs and preferences as the basic consideration, targets to improve customer’s satisfation to product conceptual design solutions. From four aspects, such as the identification of customers and their needs, the generation of conceptual design solutions, the evaluation of conceptual design solutions, and the reliability predication of conceptual products, this thesis has had an intensive study on the process model and main technologies of product conceptual design for customer satisfaction. The main research content of this thesis is as following:In the first part, the overall research about customer’s satisfaction in product innovation conceptual design stage was carried out. Firstly, the basic theory of product innovation conceptual design was analyzed. Secondly, on the basis of the research in the definition of customer’s satisfaction and the key strategies to enhance customer satisfaction of product innovation conceptual design, customer satisfaction for product innovation conceptual design process(takes the comsumer electronics as study object) is described. Finally, the key technologies of product conceptual design process for customer satisfaction were analyzed, and a general research framework was established.In the second part, customer identification and needs management of supporting product innovation conceptual design were studied. Firstly, the research process was divided into three phases, customer identification, customer needs acquirement and weight determination, needs mapping. Then a research framework was established based on the phases; Secondly, the customer evaluation system was established, and the customer identification model based on IFCA was constructed; Thirdly, customer needs acquirement and weight determination methods were studied, and through establishing the corresponding relation between customer needs and product structure, mapping of customer needs was analyzed, and the product structural innovation elements and its weight were determined; Finally, the effectiveness and the feasibility of this identification model and method were verified through an application example.In the third part, product innovation conceptual design schemes generation and decision-making methods were researched. Firstly, put the product structural innovation elements as an input and the conceptual design schemes generation as an output, a research framework for product innovation conceptual design schemes generation and decision-making was established; Secondly, creative formation of product structural elements innovation and product principle scheme design were analyzed; Then, give due consideration to the need preferences of customers, the decision goals of product innovation conceptual design schemes generation were analyzed and quantified, on the basis, a multi-objective decision model for product innovation conceptual design schemes generation was established; Finally, the feasibility and effectiveness of this proposed model and method were tested and verified through an application instance.In the fourth part, product innovation conceptual design schemes evaluation and decision methods were researched. Firstly, the research process was divided into four levels, input level, evaluation level, clustering level and output level, a research framework for product innovation conceptual design schemes evaluation and decision was established; Secondly, considering the extent of meeting customer needs and the difference between customers’ preferences, the evaluation index system was established based on the customer needs information, and a kind of an evaluation and decision model was proposed based on the customer clustering analysis, On this basis, in order to enable enterprises to respond flexibly to product demand change and rapid response to customer demand, a new customer clustering and recommended implementation process based on evaluation similarity was established; Finally, an evaluation example was given to verify the feasibility and effectiveness of this method.In the fifth part, product reliability prediction in product conceptual design phase was studied. Generated for the conceptual design solutions, in order to verify the quality defect of the final products corresponded to solutions, and to improve the feasibility of product conceptual design solutions, this thesis introduces reliability analysis into product conceptual design stage. A kind of feature similarity-based reliability prediction model was proposed. In this model, through evaluation and selection of the existing products with similar characteristics and features, and analysis and improved its failure structure, the reliability analysis and prediction of innovative product were finally achieved, so as to realize the improvement the design quality of innovative products and enhanced the customer satisfaction of the new product; Finally, the effectiveness and the feasibility of the proposed prediction model and method were tested and verified through an example.
