Knee Wrap

Client: Moji

Moji approached PDT to collaborate on the development of a superior alternative to conventional icing methods, to make the critical step of icing more practical and efficient by focusing on comfort and mobility. Moji was searching for an innovative design with a strong emphasis on flexibility, comfort, ease of use, and portability to differentiate itself from competitors and provide best in class products. The solution, a two-piece design, incorporates a Moji Compression Wrap and Moji Cold Cell, which is packaged in a reusable storage bag to prolong the life of the product.

The team conducted ethnographic and ergonomic research to understand the current user constraints of common icing methods to improve the effectiveness of its design. The findings, in conjunction with expert input from top sports medicine physicians, lead to the “X” architecture of the Moji Compression Wrap. The patent pending “X” shaped design allows the Moji Cold Cell to be strategically located around the knee, ensuring optimal placement and cooling to the key tendons and ligaments around the knee while providing an even distribution of compression that can be controlled for maximum comfort and full mobility. The team explored numerous materials to cover the cell and selected a Dri-Lex fabric to provide a barrier against the skin and mitigate the risk of frostbite, as well as eliminate wetness commonly associated with other icing solutions. The Cold Cell is secured to the wrap with Velcro, and held in place with the Compression Wrap, so the cooling does not move away from the targeted area. The team built numerous prototypes to test ergonomics, usability and effectiveness of the wrap among users. Eco-friendly packaging completes the product, and enhances its life, with a resealable storage bag to store the Moji Cold Cell in the freezer, eliminating concerns of placing it near food.
