Usability Oriented New Baren Product Design and Test Practice

Abstract

In this paper, we will carry out the design practice of usability-based baren product, that is, the design of product form. The external form design of the product needs to start from the shape, color and material of the product, find the corresponding points of the factors affecting the usability, get specific design elements, and truly transform baren product usability requirements into product language to complete the design practice. The use of curve shape in the form design of the product can better meet the demand for hand semi-clenched fist and hand comfort, which is not only fashionable with modern sense but also warm with simple life, and more in line with the modern society’s pursuit of spiritual and emotional level, but also better meet the hand comfort demand. In the baren product design, the selection of materials follows several key principles: 1) Aesthetic principle: consider whether the sensory characteristics of materials conform to the emotional transmission of products to users. 2) Principle of usability: the function of baren determines that the material should be wear-resistant material. In order to maximize the transmission of the operator’s arm power to the tool, it is necessary to consider how to avoid the skid resistance of the interactive interface and reduce the pressure of the operator’s hand muscles. 3) Principle of technology: in this study, the plastic forming process and the injection molding process of silicone are relatively mature production processes in the market, and the connection between the plastic and silicone is a breakthrough point. And 4) Economic principle: try to choose materials with low price but good processing performance, so as to produce products with good texture, and the price positioning is more suitable for the consumption level of college students. Through the above analysis and review of the literature related materials, it is finally determined that the baren chassis is made of ABS plastic which supports various processing methods, good surface gloss, heat resistance and wear resistance. Then, the surface of the baren handle can be designed with a non-slip pattern or a handle sleeve, and the handle sleeve is made of a soft rubber material, which can enhance the product feel and increase the operation comfort.
