Finger Sleeve Grip Enhancement via Textured Exterior
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Athletes face challenges in catching moving balls due to the lack of effective grip enhancement, as conventional tacky substances are either ineffective or banned in some sports, and existing solutions do not adequately address the dynamic nature of ball-catching in sports like football.
Innovation Solution
The development of grip-enhancing apparel for the hands, featuring sleeves with exterior structural materials that encircle and grip fingers, internal cushioning and reinforcing elements, and external friction-improving structures to enhance the ability to catch moving objects, which can be used alone or with conventional gloves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tacky substances are placed on hands to enhance grip, then the ability to catch balls is improved, but the substances transfer to the ball, are difficult to remove, and may be banned
Solution Approach 1:
The patent replaces chemical tacky substances with a mechanical grip enhancement system consisting of finger sleeves with textured exterior surfaces. The textured surface (featuring ribs, bumps, or other friction-enhancing patterns) provides grip through mechanical friction rather than chemical adhesion, eliminating substance transfer issues while maintaining reliable ball-catching capability
Solution Approach 2:
The invention uses flexible finger sleeves that encase the fingers, with the sleeve material itself providing the grip-enhancing textured exterior surface. This flexible shell approach allows the grip enhancement to be integrated into the finger structure without requiring separate adhesive substances, solving the contamination problem while maintaining effective grip
2Strength
If conventional gloves are used to protect hands, then hand protection is improved, but grip enhancement is insufficient for catching moving balls
Solution Approach 1:
The patent combines hand protection and grip enhancement into a single integrated finger sleeve structure. The sleeve provides cushioning protection for the finger while the textured exterior surface simultaneously enhances grip for catching balls, merging two previously separate functions into one unified device
Solution Approach 2:
The finger sleeve is designed to perform multiple functions: it protects the finger from impact, enhances grip through its textured surface, and can be worn with or without conventional gloves. This multi-functional design allows a single device to address both protection and grip enhancement needs
3Reliability
If finger sleeves with internal structure are added to enhance grip, then grip reliability is improved, but device complexity increases
Solution Approach 1:
The finger sleeve is constructed as a segmented structure with distinct functional zones: an interior cushioning layer for protection, an intermediate structural layer for reinforcement, and an exterior textured layer for grip enhancement. This segmentation allows each layer to be optimized for its specific function while maintaining overall structural integrity
Solution Approach 2:
The sleeve employs composite construction combining different materials with complementary properties: soft cushioning material on the interior, stiffening elements (such as rigid or semi-rigid inserts) in the middle layer, and friction-enhancing textured material on the exterior surface. This composite approach achieves enhanced grip and protection without requiring overly complex single-material solutions

AI summary
Apparatus worn on the fingers similarly to gloves, to enhance grip, particularly suitable as an aid in catching sports balls. The apparatus having a sheath for each finger, which may bear a friction enhancing material on an external surface. Each sheath may be internally reinforced by members which are more resistant to bending than the constituent material of the sheath. Reinforcement members may comprise bands which extend circumferentially about sheaths or may extend axially along sheaths. Sheaths may be provided with internal elastic bands which may overlie other bands at acute angles thereto or which do not overlie other bands.
