3D Scan to Product Design: Methods, Techniques, and Cases

Abstract

Abstract3D scanning technology has derived great opportunities for ergonomic product designs. This paper is aimed to introduce various research cases and methods based on 3D scanning have conducted by an ergonomics laboratory in South Korea. Sizing systems and representative 3D models developed on anthropometric measurements and 3D scan images with technical know-how were applied to the design of various products. Head, face, ear, upper limb, and waist parts, and full body in seated were anthropometrically analyzed for the design of headwear (e.g., helmet, goggle, and headphone), oxygen mask, earphone, arm-wear (e.g., watch, armband), hip protector, and vehicle seat, Customized software for the efficient analyses such as measurement of anthropometric dimensions, analysis of sizing systems, extraction of representative models, and virtual fit evaluation between products and the body were developed and applied in the product design process with massive 3D images. Representative models (e.g., torso and head) were printed in 3D for effective usage to the design and evaluation of related products. Advanced methods and techniques such as finite element modeling, morphing, and skin deformation have been applied to 3D scanned images for an advanced design of product shapes in further researches.

Estimation of Facial Contact Pressure Based on Finite Element Analysis

“…This study introduces a novel product design approach using template model registration and FE analysis methods based on 3D body scan database. As our previous research, the virtual fit analysis method [1,2,22] was proposed, which assessed the fit of an oxygen mask design (which was defined as spline curvature, either) onto 3D human faces by calculating Euclidean distances between the mask and facial surface. In the virtual fit analysis method, any material properties of both the face and mask were not considered; however, the prototype of the new oxygen mask designed based on the virtual fit analysis showed good fit and comfort compared to the existing one [23].…”

Comparative Study of 3D Reconstruction Methods for Medical Imaging

“…In the field of design, 3D scanning is the subject of various initiatives. For example, [15] describe the scanning of body parts for the design of products that need to be shaped to fit the body, such as clothing, glasses, headphones, watches, oxygen masks, prostheses or vehicle seats. [23] want to speed up and simplify the process for certain specific design cases by proposing an algorithm to automatically go from the scan of an object to its representation in CAD.…”

Bespoke and Repetitive: Converging Technologies in the Design of Custom Products

“…In the particular application of designing for ergonomic fit, scanning end users body or bodily features is increasingly leveraged in two main ways. The first way is finding the most suitable design for a wide range of people based on a variety of 3D scans and can include a multiple step process [5] often utilizing a database like the CAESAR project [6]. The second approach is made-to-measure products for specific users.…”
