Research On The Analysis Of User-oriented Image Product Form Factors And Advantage Design

In modern society, the rapid development of production technology makes products greatly abundant. Meanwhile, it leads to the increasingly fierce competition in the market. Oriented in paying close attention to perceptual demand of customers, the development pattern of improving competitive advantages of products is becoming the mainstream core gradually. Product’s shape could be the important factor for consumers to perceive directly, which seems to be particularly important for improving competitive advantages of products. Based on the Kansei engineering theory, this study constructs the spatial relationship model between product shape elements and perceptual intention of consumers through the analysis of product shape elements of daily household appliances. Product appearance analysis is also conducted by using the advantageous design method and combining the constructed relationship model, so as to improving competitive advantages of products.Through the analysis of the focus group, dominant household electrical appliances with typical characteristics are selected as the research target. Based on the method of morphological analysis, deconstruction analyses of typical samples are carried out, thus the daughter elements which are divided according to the four categories of basic shape elements of point, line, surface and body can be obtained. It establishes the vocabulary corpus by consulting relevant formation data and collecting image vocabularies used to describe these basic form elements. Through carrying out the analysis method multidimensionally, the spatial distance between the form element and the feeling image vocabulary is built and the quantitative data about the appraisal relation between the image vocabulary and the form element is obtained.According to the data of the quantitative distance between the form element and the image vocabulary, cluster analyses of the form element and the perceptual image vocabulary are carried out respectively, the typical vocabulary group and the image element group are obtained, and vocabularies which are the closest to the cluster center are chosen as the group representatives; the principal component analysis is conducted on the groups of morphologic factors to pick out the several elements with the highest effect in every group to represent the morphologic factors.Representing vocabulary of each group and their antonyms constitute a pair of image vocabularies pairs. The semantic difference experiment is carried out with the sample of representative form factors to establish the semantic difference scale table and achieve the classification data of subjective evaluation of target population on product shape elements. The regression analysis of optimal scale is made based on these data to construct the regression model of the degree of the influence between the form factor and the subjective image, and the accuracy of the model is verified by using a statistical test method.Based on the advantage design, combining with the form element regression analysis of optimal scale image model we got before, the paper studies the methods of product’s advantage design, confirms the main process of the design of the superior form, and ascertains the degree of influence of every form element by analyzing the example of three mini-fridges, after the form element deconstruction analyses, the focus group’s analysis and the weight analysis. Besides, the paper adopts regression model to analyze the sensuous image which every mini-fridge has brought to consumers.
