Solution Overview
Problem
Weightlifting wraps face issues with slippage, limited rebound potential, and instability, which can lead to reduced support, increased risk of injury, and difficulty in application, affecting performance and safety.
Innovation Solution
The use of weightlifting wraps with exposed elongate pliable strand members arranged in an offset lattice configuration on the outer surface, providing sufficient friction to prevent slippage and enhancing rebound potential while allowing easier application and increased stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional weightlifting wraps are used, then they provide basic joint support, but they suffer from slippage between layers that reduces support effectiveness and causes instability
Solution Approach 1:
The patent applies local quality by adding raised friction-resistant features (ridges, bumps, or textured patterns) to specific regions of the wrap surface where layer contact occurs. This creates localized high-friction zones that prevent slippage between wrap layers during joint movement, while the rest of the wrap maintains its original flexible properties for comfort and rebound.
2Use of energy by moving object
If yarn or cloth material is used in wrap, then it provides basic wrapping function, but it provides inferior rebound compared to elastic materials
Solution Approach 1:
The patent uses composite materials by combining yarn or cloth material with elastic elements (such as elastic bands, rubber strips, or spring-like structures) integrated into the wrap construction. This composite structure provides both the wrapping function of the fabric and the rebound properties of the elastic materials, achieving superior energy return without requiring the wrap to be densely wound.
3Use of energy by moving object
If wraps are densely wound to increase rebound, then rebound potential improves, but the modulus required exceeds what a single lifter can apply and circulation is reduced
Solution Approach 1:
The patent applies segmentation by dividing the wrap into multiple functional layers or sections: an outer layer for rebound (elastic material), a middle layer for friction resistance (with raised features), and an inner layer for comfort and joint contact. This segmented structure allows each layer to perform its specific function independently, providing high rebound without requiring excessive wrapping tension that would compromise circulation or application feasibility.
4Stability of the object's composition
If gym chalk or sticky spray is applied to prevent slippage, then friction between layers increases, but it creates residue, is difficult to clean, and requires additional time and space
Solution Approach 1:
The patent applies self-service by incorporating friction-resistant raised features directly into the wrap material structure itself. The wrap is self-sufficient in providing grip between layers through its built-in textured surface, eliminating the need for external substances like gym chalk or sticky spray. This integrated solution prevents slippage without requiring additional products, application steps, or creating messy residue.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution prevents slippage, increases kinetic energy return, simplifies wrapping, and enhances joint stability, leading to improved performance and reduced risk of injury during weightlifting exercises.
Implementation Method 1
Weightlifting wraps are typically constructed from flexible or elastic material that rebounds from being stretched. As the knee moves into flexion, the knee wraps are compressed, thereby storing potential energy. As the knee is extended, and the angle of knee flexion decreases, the wraps 'rebound' and return the potential absorbed in compression into kinetic energy.
Implementation Method 2
The exposed strand members are arranged in an offset lattice configuration. In some embodiments, the exposed strand members have a coefficient of friction sufficient to grip the previous layer of the wrap.
