Using a 3D Body Scanner in Designing Compression Products Supporting External Treatment

Abstract

The work comprises a statistical tolerance analysis of human body dimensions using a 3D body scanner and its impact on the value of unit pressure exerted by a compression product on the subject’s body. Model calculations of changes in unit pressure due to the susceptibility of the human body were carried out on the basis of the Laplace law using experimentally determined values of circumferences of particular parts of a female subject, with and without a compression product. Experimentally documented changes in the body circumferences under the influence of a compression garment are one of the reasons for the differences between the intended and actual pressure value exerted by the product.

Designing Seamless Compression Products Supporting the Process of External Treatment on Numerically Controlled Flat Knitting Machines

“…In the process of designing compression products, regardless of the technique, the following factors are important and influence the intended value of unit pressure: n dimensioning accuracy of body circumferences G1 and their distance from the base [6,7] which, in relative terms, means that the errors fall within ± 0.1%.…”

Draft Design Solution for Automated 3d Scanning of Persons

“…If you store the results of regular scanning, the changes can be observed with time. 3D scanners for human body were used by Krzysztof Kowalski's [Ilska 2017] team in their project of designing compression products used for external treatment. The scanner has been used to obtain statistical tolerance analysis of human body.…”

Methods of Evaluating Knitted Fabrics with Elastomeric Threads in the Design Process of Compression Products

“…Improving the accuracy of determining circumferences G 1 can be achieved by eliminating manual dimensioning of the human body and replacing it with the 3D scanning technique [7][8][9][10][11][12][13].…”

“…This leads G 1 , an important stage in the design process of compression products becomes taking into account the complex relations between force F and relative elongation ε in dependence on the stretching range. In most works [13][14][15] on the modeling of compression products, a constant value of longitudinal rigidity of the fabric is adopted, irrespective of the relative elongation. In model studies, such an approach can be justified.…”

“…Comparing unit pressure values calculated according to the analytical model and with the finite element method revealed differences in the range of 1-7%. On the other hand, works [13,15] analysed the influence of the seam, the intended dimensional tolerances of body parts and the manufacturing tolerance of the compression product on the value of unit pressure in dependence on the longitudinal rigidity of the compression fabric. Different aspects concerning the design and modeling of compression products are presented in a review article [16].…”
