Development of bulletproof pad design system using 3D body scan data

Abstract

Purpose The purpose of this paper is to develop a system to design a bulletproof pad for chest protection using three-dimensional body scan data. Design/methodology/approach Body data were divided into arbitrary number of groups based on the standard normal distribution theory, considering the width and height of the upper body. Several parameters were used to define the cover area of the bulletproof pad, and the shape of this area of each model in a group was averaged to generate the standard bulletproof pad model for that group. Findings It is possible to use three-dimensional body scan data in the design process of a mass-customized bulletproof pad for chest protection. Practical implications It is expected that it would be possible to design not only bulletproof pad but also many kinds of body-related products that need to reflect the shape of body using the methodology developed in this study. Social implications Using this system, the mass customization of special garments and equipment would be possible, which will improve the wearers’ comfort and work efficiency. Originality/value Three-dimensional body measurement, parametric definition of cover area and user interface for shape modification developed in this study will facilitate the consumer-oriented product design.
