Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current working gloves with textured surfaces for improved grip and perspiration management often compromise dexterity, ease of donning, and mechanical performance, leading to frequent rupture and contamination issues.
Innovation Solution
An ambidextrous working glove with fish scale-textured inner and outer surfaces is created using a method involving a series of polymer solutions and coagulants, where a former with a fish scale-textured surface is coated and the glove is formed through a process that includes dipping, drying, and stripping, ensuring compliance with various safety standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a textured surface is added to working gloves to improve grip and perspiration management, then gripping ability and comfort are improved, but dexterity and mechanical performance deteriorate
Solution Approach 1:
The patent applies different surface textures to different regions of the glove based on functional requirements. The palm and finger surfaces receive a first texture pattern optimized for gripping, while the back of the hand receives a second texture pattern optimized for perspiration management. This localized differentiation allows each region to perform its specific function without compromising overall glove performance.
Solution Approach 2:
The glove surface is divided into multiple textured regions with distinct patterns. The first texture pattern covers the palm and fingers for enhanced grip, while the second texture pattern covers the back of the hand for perspiration control. This segmentation allows independent optimization of each region's surface properties without affecting the other regions' performance.
2Ease of operation
If donning powders are used to ease glove donning, then ease of donning is improved, but contamination and skin irritation occur
Solution Approach 1:
The patent introduces an intermediary substance applied to the wearer's hand rather than using traditional donning powders inside the glove. This intermediary layer facilitates easy donning by reducing friction between the hand and glove interior, while being contained in a controlled application system that prevents contamination and skin irritation associated with loose powders.
Solution Approach 2:
The patent replaces the mechanical system of loose donning powders with a controlled application mechanism. Instead of relying on free-flowing particles that can contaminate and irritate, the system uses a controlled delivery method to apply a specific substance, eliminating the harmful effects while maintaining the ease of donning benefit.
3Quantity of substance
If cotton flock lining is added to absorb perspiration, then perspiration absorption is improved, but effectiveness is lost after absorbing small amounts
Solution Approach 1:
The patent employs porous material structures on the glove interior surface that provide sustained perspiration management. The porous architecture allows for continuous wicking and evaporation of moisture, maintaining effectiveness throughout extended wear periods rather than becoming saturated quickly like cotton flock lining.
Solution Approach 2:
The patent uses textured surface patterns that replicate natural perspiration management mechanisms. The surface texture creates micro-channels and pathways that guide perspiration away from the skin, mimicking efficient natural drying processes and maintaining long-term effectiveness without the rapid saturation problems of absorbent materials like cotton.
