With the development of science and technology and the complexity of design objects, the requirements for product modeling design are getting higher and higher. How to design products in a targeted manner to meet the needs of consumers has become a key issue for enterprises. In order to improve the efficiency of product design, this article has carried out a research on the design of a new refrigerator product that a company plans to launch based on virtual reality technology. First, based on the conventional new product launch process, virtual reality technology is incorporated in the two links of market research and prototype testing. The virtual research client was tested after research and development. The average score was 9.32 for stability, 9 for ease of operation, and 8.86 for experience comfort. After optimizing the comfort level, a virtual survey was randomly launched on the home appliance shopping website. Analyze the general situation of 1258 users, the factors that affect refrigerator buying behavior, and the acceptable price of refrigerators. Among the 1,258 users who participated in the virtual survey, the male to female ratio was 0.9:1, and the age was mainly between 25 and 35. The number of people with high school education was the largest, accounting for 39.6%, 46% of users believe that price is the primary factor they consider when buying a refrigerator, and the generally accepted range is around 3,000 yuan. After obtaining sufficient demand and market information, develop new products, build a virtual design database, perform scene modeling, texture mapping, and achieve interactive effects. Of the 739 users who participated in the virtual experience, only 526 of them thought it was more comfortable during the experience. Therefore, it is necessary to improve the comfort during the experience. Only 59 people are very satisfied with the appearance of the refrigerator, and the appearance of the new refrigerator should be adjusted in time to meet market demand. The user's purchase intention ratio for the three refrigerators A, B and C is 1:3:1.6, and production can be arranged according to this ratio. The total cost of virtual design is 154,800 yuan less than traditional design, and the total time is 23 days less. This shows that product modeling design based on virtual reality technology can save costs and improve efficiency, and it is worth promoting.
