초록
This study aims to develop knee protectors that provide high safety and fitness, while incorporating a motion-adaptable 3D-printed pad. These protectors were evaluated by individuals who experience knee discomfort or pain. Theresults are as follows. First, the 3Dprinted pad design of a hexagonal mesh structure, which is modeled for excellentappearance and knee movement. Each unit of the mesh has a outer layer of 2mm thick, a spacer layer of 1 mm in diam-eter, and is connected by a 1.5 mm bridge. The bridge was extended up to 1.2 cm. Second, the knee brace was designedin three types - cylinder, strap, and combination by Universal design. Impact protection measurements of the three kneeprotectors demonstrated roughly 80% reduction in impact. Third, based on usability evaluation, cylinder type protectorshave the highest ratings in most areas, primarily because of their ease of use. The strap type protector received positivereviews in terms of appearance and care, and the combination type provided stable knee protection. This study demon-strated the potential industrial application of 3D printing technology by designing and evaluating protective products forthe human body. The results of this study are expected to aid knee protector manufacturers in developing practical prod-ucts and promoting the development of protective equipment for other body parts or purposes.
