Arch-Shaped Hard Member Athletic Protector Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional athletic protectors, such as arm guards, often slip off the arm before the belt can be securely fastened, making them inconvenient to wear during athletic activities.
Innovation Solution
The athletic protector features an interior portion with at least one hard, elastically deformable member formed in an arch shape, which provides stability and secure fitting, allowing for a stable operation of winding the belt portion around the arm or leg.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the athletic protector is designed to cover only one-half or less of the arm circumference, then the protector is more flexible and easier to put on, but the protector slips off the arm before the belt can be fastened
Solution Approach 1:
The hard member is formed in an arch shape with specific curvature ratios (L2>L1/2 and L3<L1), creating a rounded, arc-shaped structure that conforms to the arm's contour. This curvature provides stable contact with the arm surface, preventing the protector from slipping off during the fastening process while maintaining ease of application.
2Adaptability or versatility
If the hard member has high elasticity for comfort, then the protector fits better, but the protector may deform excessively and become unstable
Solution Approach 1:
The patent specifies precise geometric parameters for the arch-shaped hard member (L2>L1/2 and L3<L1) that define its elastic deformation characteristics. These parameter constraints ensure the hard member has optimal elasticity for comfort while maintaining sufficient structural stability to prevent excessive deformation and maintain protector stability during use.
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
This design ensures that the athletic protector can be readily worn since the operation of winding the belt portion is stable, providing enhanced protection and convenience during athletic activities.
Implementation Method 1
The hard member is formed in an arch shape, is elastically deformable

AI summary
An athletic protector includes: an interior portion; an exterior portion configured to cover the interior portion; and a belt portion configured to be securable to the exterior portion. The interior portion includes at least one hard member. The hard member is formed in an arch shape, is elastically deformable, and has a length L1 in a width direction, a length L2 in a height direction orthogonal to the width direction, and a length L3 between both ends along the width direction. Length L1 in the width direction and length L2 in the height direction have a relation of L2>L1/2. Length L1 in the width direction and length L3 between both ends have a relation of L3<L1.
