This technology is a non-powered wearable variable impedance device that corrects posture and assists muscle strength by inducing cable tension and elastic deformation based on the user's body movements. It features a mechanism that increases tension during upper body flexion by positioning upper and lower strings around a spinal connection point.
There is a risk of injury from improper posture, such as bending the waist during squatting or lifting tasks, and existing posture correction exercise equipment has significant limitations in usability due to its bulkiness and lack of portability.
This technology proposes a structure that combines a wearable cable system with elastic components. By adjusting the distance between strings and their tension according to changes in joint angles, it encourages the back to straighten and provides muscle assistance during knee flexion, achieving variable impedance through body movement alone without an external power source. It reduces the risk of injury in environments involving repetitive strain on the lower back, such as logistics loading/unloading, construction site work, and elderly care, and its lightweight, non-powered, and portable design makes it easy to implement in real-world settings.
