Elastic Arm Sleeve for Throwing Motion Muscle Assistance

The patent changes the functional parameter of the elbow support from passive structural compression to active elastic energy storage and release. The elastic member is configured to store energy during the winding-up motion and release it during acceleration, fundamentally changing how support is provided while reducing harmful forces on the UCL.

The patent converts the harmful valgus and varus forces that normally injure the UCL into beneficial elastic energy storage. By positioning the elastic member to experience tension during the throwing motion, the harmful forces are captured and converted into useful energy that assists muscle function and reduces overall load on the ligament.

The patent replaces static rigid braces with a dynamic elastic system that adapts to the throwing motion. The elastic member dynamically stores and releases energy throughout the motion cycle, providing both joint stability and active muscle assistance, unlike rigid braces that simply restrict movement.

The elastic member performs preliminary action by storing energy during the winding-up phase before the actual throw. This pre-stored energy is then released during the acceleration phase to assist muscle function, providing proactive support rather than reactive restriction.

The elastic member acts as an intermediary between the harmful forces and the UCL. Instead of allowing forces to directly load the ligament, the elastic member intercepts these forces, stores them as elastic energy, and releases them in a controlled manner that assists rather than harms the joint.

The patent changes the force parameter by introducing an elastic element that transforms constant compression forces into dynamic tension and release cycles. This parameter change converts harmful sustained loads into beneficial pulsating assistance that reduces overall UCL stress.
