Embossment Design for TPE Glove Durability and Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thermoplastic elastomer (TPE) gloves suffer from poor durability and gripping performance, with existing embossment solutions failing to balance these aspects effectively without increasing manufacturing costs.
Innovation Solution
A specific embossment design featuring a base surface, raised surface, and recessed areas with varying depths and sizes, between 50% to 99% relative to the embossment height, providing a three-dimensional pattern or shape that enhances durability and gripping performance without excessive cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If overlapping textures or embossed patterns are added to TPE gloves, then gripping performance is improved, but manufacturing cost increases
Solution Approach 1:
The patent applies parameter changes by precisely controlling the depth of recessed areas (50%-99% of embossment height) and size (0.05mm-5.00mm) to optimize gripping performance. This quantitative parameter optimization allows achieving enhanced grip without requiring complex multi-layer structures or expensive materials, thus resolving the contradiction between performance improvement and manufacturing cost.
Solution Approach 2:
The patent implements local quality by creating specific recessed areas within embossments at strategic locations on the glove surface. These localized features (with depth 50%-99% of embossment height) provide enhanced gripping precisely where needed during handling operations, rather than uniformly across the entire glove surface, thereby improving grip performance while minimizing additional manufacturing complexity and cost.
2Strength
If conventional embossed patterns are applied to TPE gloves, then durability is improved, but gripping performance remains insufficient
Solution Approach 1:
The patent applies segmentation by dividing each embossment into distinct structural components: a base surface, a raised surface, and recessed areas extending between them. This segmented structure creates multiple functional zones within each embossment feature - the raised portions provide durability through structural reinforcement, while the recessed areas (depth 50%-99%) create mechanical interlocking with handled objects to enhance gripping performance simultaneously.
Solution Approach 2:
The patent employs composite material principles by combining TPE base material with embossed structural features that integrate different functional properties. The embossed patterns with controlled recessed areas (0.05mm-5.00mm size, 50%-99% depth) create a composite structure where the raised portions maintain material integrity and durability, while the recessed zones provide enhanced surface friction and mechanical engagement for superior gripping performance.

AI summary
An embossment (100) on a sheet of film and a glove produced from the embossed sheet of film is disclosed. The embossment (100) comprises a base surface (103); a raised surface (102) opposite to the base surface (103); and at least one recessed area (104) formed therein and extending from the base surface (103) and the raised surface (102) to the base surface (103), wherein depth (Dr) of the recessed area (104) is between 50% to 99% relative to height (He) of the embossment (100) between the base surface (103) and the raised surface (102).
