Abstract

This study aims to develop three dimensional (3D) yoga knee protectors that provide excellent wearing comfort. Three types of pads were modeled using 3D human data: two types of 3.0-cm-wide pads separated into top and bottom with thicknesses of 0.1 cm (TPU-1: A) and 0.2 cm (TPU-2: B); and one type with three 0.2-cm-thick separated panels (TPU-S: C). Based on these models, five knee protectors were developed using 3D patterning and 3D printing. Types A, B, and C were integrated with 0.6-cm neoprene pads. Type D was fabricated with a donut-shaped 0.6-cm neoprene pad inserted, while Type E consisted of two discrete 0.6-cm neoprene pads embedded in the protector's upper and lower sides. Wearing comfort was evaluated in terms of fit, pressure, and cushioning while in a standing and kneeling position and while in motion. The findings suggest that the fabricated knee protectors were evaluated as comfortable to the individuals with knee pain, rather than those without knee pain. The individuals with knee pain preferred the soft pads made of neoprene positioned around the knee (NEO-S: E), while those without knee pain favored the cushioned pads with a pattern structure maintained by thin 3D-printed pads (TPU-1: A).
