Appearance Design Method of Household Beauty Instrument Based on Kansei Engineering

Objective: To explore the application of Kansei Engineering in the appearance design of household beauty instruments. Methods: Through investigation, the appearance samples, design elements and main Kansei words of the product are determined. The semantic difference method was used to quantify the users' perceptual cognition. According to the scores of each sample, the influence of the appearance and shape characteristics of each element on perceptual cognition in the product design was analyzed. Unity3D was used to establish a Kansei Engineering system for the appearance design. Conclusion: The bending degree, roundness degree, torsion degree, shape symmetry degree and regular degree of product shape contour curve will have a direct influence on the perceptual cognition tendency of users. Using Kansei Engineering method to establish an auxiliary design system of the household beauty instrument appearance can facilitate the designers obtain more suitable shapes for reference according to the expected positioning of product.
