Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing gloves lack adequate grip properties and abrasion resistance, with closed-celled foamed coatings providing poor grip and open-celled coatings offering enhanced grip but poor protection against germs and microbes, while also being less abrasion-resistant.

Innovation Solution

A supported glove with a polymeric, elastomeric, or latex coating featuring raised thermoplastic or thermoset materials, where the coating and raised features are made from different polymeric compositions, such as nitrile-butadiene and polyurethane, to enhance grip in both dry and wet environments, and the manufacturing process includes knitting a fabric liner, dipping it in a polymeric composition, and applying raised features before curing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If closed-celled foamed coating is used, then protection against germs and microbes is improved, but grip properties deteriorate

Engineering Contradiction:

Improveprotection against germs and microbesVSAvoidgrip properties

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies different surface characteristics to different regions of the glove. The palm and finger surfaces feature raised dots that provide enhanced grip, while the coating material itself (whether open-celled or closed-celled foam) provides the barrier protection. This local differentiation allows the glove to simultaneously achieve both protection and grip without requiring separate glove types.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If open-celled foamed coating is used, then grip properties are improved, but protection against germs and microbes deteriorates

Engineering Contradiction:

Improvegrip propertiesVSAvoidprotection against germs and microbes

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The raised dot features are applied locally to the palm and finger areas where grip is needed, while the coating material provides the protective barrier. This allows the glove to achieve both functions through spatial differentiation rather than requiring the entire coating to have both properties simultaneously.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If open-celled foamed coating is used, then grip properties are improved, but abrasion resistance deteriorates

Engineering Contradiction:

Improvegrip propertiesVSAvoidabrasion resistance

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The raised dot features are concentrated on the palm and finger surfaces where grip is required, while the coating material provides the structural integrity and abrasion resistance. This local application strategy allows the glove to achieve enhanced grip without compromising the overall durability of the coating.

Inventive Principle:

Principle #3Local quality

4Ease of operation

If multiple glove types are used to satisfy different requirements, then grip properties in different environments are improved, but device complexity increases

Engineering Contradiction:

Improvegrip properties in different environmentsVSAvoidnumber of glove types

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent creates a universal glove design that combines a protective coating (open-celled or closed-celled foam) with raised dot features on the palm and fingers. This multi-functional design allows a single glove type to provide both protection and enhanced grip in various environments, eliminating the need for multiple specialized glove types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The glove combines different materials and structures: a protective coating layer (foam rubber or similar material) with raised dot features (which may be the same or different polymeric material). This composite structure integrates the protective and grip-enhancing functions into a single unified product.

Inventive Principle:

Principle #40Composite materials
