Innovative Design of Home Electric Nasal Washer based on Kansei Engineering

Abstract

With the increasing problem of air pollution and the increase of rhinitis patients, nasal cleaning has become a problem, and the home electric nasal washer has a good market prospect as the main device for nasal rinsing. The study applied the methods related to Kansei Engineering to quantify the perceptual vocabulary, including collecting and screening the perceptual element vocabulary, selecting representative product samples, and establishing the perceptual imagery space using the semantic difference scale. Then the data evaluation results were input into the software SPSS for factor analysis and principal component analysis, and the key words of design elements that meet users' needs were determined to be "mild", "safe", "clean " "comfortable", representing the user's perceptual preference for the electric nose washer. Combined with the product samples, we analyzed the correlation between users' perceptual imagery and product elements, summarized the design points, and finally designed the product based on the design points. The study provides a new way of thinking and direction for the design of electric nasal wash for home use that is integrated with the user's affective needs.
