Solution Overview
Problem
Joint fatigue, pain, and instability, particularly in hinge joints like the knee and elbow, are common issues due to degenerative wear and damage, for which existing external supports often fail to provide adequate relief and motion assistance.
Innovation Solution
The development of elastically stretchable frameworks with permanent openings and adjustable tensioning mechanisms that fit snugly around joints, storing and releasing kinetic energy to enhance joint motion and provide support, comfort, and protection during daily activities and rehabilitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing external supports are used for joints, then joint support is provided, but joint motion assistance and kinetic energy return are insufficient
Solution Approach 1:
The support framework transitions from a static structure to a dynamic energy-storing system. The framework is configured to store kinetic energy during joint flexion and release it during extension, creating a dynamic interaction that actively assists joint motion rather than merely providing passive support.
Solution Approach 2:
The invention changes the mechanical parameters of the support system by introducing energy storage capability. The framework's elasticity and tension characteristics are optimized to capture and return kinetic energy, transforming the support from a purely structural element to an energy-active system that enhances joint performance.
2Stability of the object's composition
If a tight-fitting support framework is used, then joint stability is improved, but comfort and ventilation are reduced
Solution Approach 1:
The support framework incorporates an open-work or mesh structure that provides porosity. This allows air circulation and ventilation through the framework while maintaining structural integrity and joint stability. The porous design reduces the harmful effect of poor ventilation and discomfort associated with tight-fitting supports.
Solution Approach 2:
The framework uses flexible, form-fitting materials that conform to the body's contours. This flexibility allows the framework to provide stable support while adapting to natural body movements and maintaining comfort. The thin, flexible construction enables ventilation and reduces the oppressive feeling of tight supports.
3Adaptability or versatility
If an expandable framework is used, then fit and support are enhanced, but device complexity increases
Solution Approach 1:
The framework is divided into multiple segments or zones with different tension and elasticity characteristics. This segmentation allows each portion to be optimized for specific support requirements while collectively providing overall adaptability. The modular segmented structure achieves complex fit requirements without requiring an overly complicated monolithic design.
Solution Approach 2:
The expandable framework serves multiple functions simultaneously: it provides structural support, stores and releases kinetic energy, adapts to different body sizes and shapes, and maintains ventilation. This multi-functionality reduces the need for separate components, thereby managing complexity while enhancing adaptability and support characteristics.

AI summary
A method of donning a potentiating support includes: positioning a framework in abutment with an area of a body such that the framework spans a hinge joint, the framework defining a plurality of permanent openings extending completely through the framework and being bounded by the framework, wherein the framework, along its entire boundary with an opening, is elastically stretchable between a first initial state and extended states and, when expanded to a said extended state, the framework stores potential energy that is released as kinetic energy upon its return to the initial state such that the framework provides joint potentiation to the spanned hinge joint; applying tension proximate each of opposite sides of the framework such that the framework is expanded and the surface of the framework is tensioned in its abutment with the body; and securing the expanded framework in its forced abutment with the area of the body.
