Glove Cuff Gripping Aid With Structured Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gloves are difficult to remove without coming into contact with soiling or contamination, as they lack effective gripping aids that enhance the removal process.
Innovation Solution
A glove design featuring a gripping aid with a structured surface on the cuff and structured surfaces at the ends of finger spaces, allowing for improved grip and interlocking with fingertips, reducing the risk of slipping during removal. The gripping aid is integrated into the glove body and positioned near the rolled edge for enhanced tear strength and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smooth gripping aid is used on the cuff, then the glove is easy to manufacture, but the gripping aid slips during removal making it difficult to remove without contamination
Solution Approach 1:
The patent applies local quality by providing structured surfaces (knobs and/or grooves) only at specific locations where grip is needed - namely at the gripping aid on the cuff and at the fingertip intake regions - while the rest of the glove surface remains smooth. This localized structuring improves grip stability during removal without unnecessarily complicating the overall glove design or manufacturing process.
Solution Approach 2:
The patent employs curved or rounded surface features (knobs) as part of the structured surface at the gripping aid and fingertip regions. These curved geometries provide better contact area and mechanical interlocking with fingers during glove removal, enhancing grip stability compared to flat or sharp-edged features.
2Strength
If the gripping aid is positioned far from the rolled edge, then it is less visible and may cause discomfort, but positioning it closer enhances tear strength and visibility
Solution Approach 1:
The patent positions the gripping aid partially close to the rolled edge (within 10mm) to achieve enhanced tear strength and visibility, but not necessarily directly at the edge. This partial approach provides sufficient structural reinforcement and visibility while maintaining comfort by avoiding excessive proximity that might cause discomfort during wear.
3Reliability
If structured surfaces are added to the glove, then grip and removal safety are improved, but manufacturing complexity increases
Solution Approach 1:
The structured surfaces (knobs and/or grooves) are applied locally only at critical grip points - the gripping aid on the cuff and the fingertip intake regions - rather than across the entire glove surface. This localized application maintains manufacturing simplicity by limiting the complexity to specific areas where it provides maximum benefit for removal safety.

AI summary
The invention relates to a glove having at least one gripping aid arranged at the periphery of the cuff, the surface of which gripping aid at least partially has patterning, especially knobs and/or grooves, wherein the glove at least two of the total five finger spaces which are adapted to the fingers of a hand also has a structured surface or patterning, respectively, especially knobs and/or grooves, essentially at the ends of each finger space opposite the cuff which are provided for intake of the fingertips.
