Wrist Protector Bending Element Elastic Restoring Force
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrist protectors for sport gloves either limit mobility or create undesirable sudden stops during bending, and their complex constructions make them unsuitable for preventing wrist hyper-extension effectively.
Innovation Solution
A wrist protector with a bending element that changes length during wrist movement, generating an elastic restoring force to prevent hyper-extension while allowing full range of motion, comprising a first and second plate connected by an elastic element, which can be easily integrated into a sport glove and adapted for different situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rigid braces with mechanical stops are used to prevent wristhyper-extension, then protection againsthyper-extension is improved, but mobility of the wrist is limited and sudden impact forces are generated
Solution Approach 1:
The patent replaces rigid mechanical stops with a dynamic elastic element that continuously adapts to wrist movement. The elastic element provides progressive resistance during extension while allowing full range of motion, eliminating the sudden stop effect of rigid braces and maintaining wrist mobility throughout the bending cycle.
Solution Approach 2:
The elastic element acts as a cushioning mechanism that absorbs impact forces before they can cause injury. By providing continuous elastic resistance during wrist extension, the element prevents sudden impact forces from reaching the arm, while still allowing the wrist to achieve its full range of motion without mechanical stops.
2Reliability
If semi-rigid elements are used on the back of the hand, then protection againsthyper-extension is provided, but mobility of the hand is substantially limited
Solution Approach 1:
The patent utilizes changes in the physical parameters of the elastic element (its length and stiffness) during wrist movement. As the wrist extends, the elastic element stretches and changes its effective stiffness, providing protection only when needed while maintaining flexibility during normal movement, thus preserving hand mobility.
Solution Approach 2:
The elastic element is positioned specifically in the overlap area between the first and second plates, creating a localized protection zone at the wrist joint. This localized approach provides targeted protection againsthyper-extension without restricting the overall mobility of the hand, as the element only interferes with movement in the specific direction of excessive extension.
3Reliability
If compression-proof bodies are arranged on a non-yielding layer, then protection againsthyper-extension of fingers is achieved, but the construction becomes complex and manufacturing difficult
Solution Approach 1:
The patent merges the protective function with the existing glove structure by integrating the elastic element directly into the wrist protector assembly. The first and second plates are positioned to overlap with the elastic element, creating a unified structure that provides protection without requiring separate complex mechanisms or multiple layers of compression-proof bodies.
Solution Approach 2:
The wrist protector is divided into distinct functional segments: the first plate, the second plate, and the elastic element. This segmentation allows each component to perform its specific function independently while simplifying the overall construction and manufacturing process, avoiding the complexity of integrated multi-layer compression-proof structures.
