Fish Scale-Textured Glove Molding for Uniform Thickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing working gloves with textured surfaces face issues of reduced dexterity, difficulty in donning, and increased frequency of failure due to non-uniform thickness and inadequate perspiration management, often using methods that compromise mechanical performance.
Innovation Solution
The ambidextrous working glove is manufactured using a former with a fish scale-textured surface to directly transfer texture to both inner and outer surfaces, ensuring uniform thickness and improved grip, while utilizing polymer solutions to enhance durability and perspiration management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a textured form is used to impart texture to the inner surface and the film is eroded or particles are sprayed to create outer surface texture, then the glove provides improved grip and perspiration management, but the glove exhibits non-uniform thickness leading to rupture and reduced dexterity
Solution Approach 1:
The fish scale texture is pre-formed on the interior surface of the mold before glove manufacturing. This preliminary action ensures that when the glove material is applied, the texture is already in place, allowing for controlled material distribution and uniform thickness while achieving the desired surface texture for grip and perspiration management.
Solution Approach 2:
The fish scale texture pattern is copied from the mold's interior surface to the glove's inner surface through direct contact during manufacturing. This copying process creates the textured surface needed for improved grip and perspiration management without requiring post-manufacturing erosion or particle spraying that would compromise thickness uniformity.
2Reliability
If erosion treatment or particle spraying is applied to create outer surface texture, then grip performance is improved, but dexterity and tactile sensation are reduced
Solution Approach 1:
The fish scale texture is applied specifically to the palm and finger surfaces where grip is needed, while keeping other areas smoother. This local application of texture provides enhanced grip performance in critical areas without compromising overall dexterity and tactile sensation across the entire glove surface.
3Ease of operation
If donning powders such as cornstarch or talc are used to facilitate glove donning, then ease of donning is improved, but contamination of wounds, skin irritation, and mechanical interference with procedures occurs
Solution Approach 1:
The glove is designed as a disposable product with a smooth inner surface that facilitates donning without requiring donning powders. The disposable nature eliminates the need for powders that could cause contamination or irritation, while the smooth surface provides sufficient ease of donning for single-use applications.
4Reliability
If cotton flock linings are used to absorb perspiration, then perspiration management is improved to some extent, but the lining loses effectiveness quickly and reduces dexterity
Solution Approach 1:
The fish scale texture creates a porous surface structure on the inner glove that allows perspiration to flow away from pressured surfaces. This porous design provides effective perspiration management while maintaining dexterity, as the texture is integrated into the glove material itself rather than adding a separate absorbing lining.
