Perforated Polymeric Coating for Breathable Protective Gloves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective gloves lack adequate ventilation in high-temperature environments, leading to discomfort and reduced grip due to compromised protection and air circulation.
Innovation Solution
A protective glove design featuring a knit fabric hand shell with a polymeric coating that gradually diminishes in thickness from the palm side to the back side, combined with a plurality of perforations less than 0.2 mm in diameter, providing ventilation and increased friction for enhanced grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a polymeric coating is applied over the palm side to provide grip and protection, then abrasion resistance and grip are improved, but breathability and ventilation are compromised
Solution Approach 1:
The polymeric coating incorporates a plurality of perforations extending through it, creating a porous structure that allows air circulation while maintaining the coating's protective and grippable functions. The perforated design enables ventilation to reduce heat buildup and perspiration while the polymeric material itself provides abrasion resistance and enhanced grip coefficient of friction.
2Strength
If the polymeric coating thickness is increased to enhance protection and grip, then abrasion resistance is improved, but breathability and air circulation are reduced
Solution Approach 1:
The polymeric coating has a thickness that gradually diminishes from the palm side to the back side of the hand portion. The palm side maintains sufficient thickness for grip and protection, while the back side becomes thinner to allow ventilation through the knit fabric, creating local variations in coating properties to balance protection and breathability.
3Object-affected harmful factors
If perforations are added to provide ventilation, then breathability is improved, but the coefficient of friction and grip may be compromised
Solution Approach 1:
The polymeric coating is designed with a plurality of perforations that create a porous structure. This porous design allows air circulation for ventilation while the surrounding polymeric material maintains sufficient surface area and texture to provide the necessary coefficient of friction for grip. The perforations are distributed to balance ventilation needs with grip requirements.
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
The design significantly improves breathability, reduces hand temperature, and minimizes perspiration while maintaining abrasion resistance and grip, balancing ventilation and protection.
Implementation Method 1
The back side of the hand portion has an area that is free of the polymeric coating to provide ventilation to the user's hand through the knit fabric hand shell. A plurality of perforations are uniformly dispersed over the palm side of the hand portion. The perforations have a diameter less than 0.2 millimeters (mm) and extend though the polymeric coating to provide ventilation to the user's hand

AI summary
A protective glove including a knit fabric hand shell having a cuff portion and a hand portion that includes a back side opposite a palm side for covering opposing sides of a user's hand. A polymeric coating covers the palm side of the hand portion and has a thickness that gradually diminishes from the palm side to the back side of the hand portion. The back side of the hand portion has an area that is free of the polymeric coating to provide ventilation to the user's hand through the knit fabric hand shell. A plurality of perforations is uniformly dispersed over the palm side of the hand portion. The perforations have a diameter less than 0.2 mm and extend though the polymeric coating to provide ventilation to the user's hand and to increase a coefficient of friction for an exterior surface of the polymeric coating.
