Solution Overview

Problem

The production of gloves with a gripping aid often results in inhomogeneous material distribution and small holes due to insufficient material adhesion in the 'crotch area' between the gripping aid and the finger space, leading to defects and contamination issues during removal.

Innovation Solution

A molded body with a structured surface at the base of the gripping aid and on fingertips, featuring varying degrees of structuring to enhance material adhesion and prevent air bubble formation, ensuring uniform material thickness and reduced pinholes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a gripping aid is added to the molded body, then the grip function is improved, but material adhesion becomes insufficient in the crotch area and small holes appear

Engineering Contradiction:
Improvegrip functionVSAvoidmaterial adhesion
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies different surface structuring to different areas of the molded body. The gripping aid area has a structured surface with higher roughness to enhance material adhesion, while other areas maintain their original smooth finish. This local differentiation resolves the contradiction by providing enhanced grip function where needed without compromising material adhesion elsewhere.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes the surface roughness parameter specifically in the crotch area and on the gripping aid. By increasing the roughness parameter in these specific locations, the material adhesion is improved, preventing small hole formation while maintaining the gripping aid's functional benefits.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If the gripping aid redirects material flow, then the grip structure is formed, but material distribution becomes uneven and holes appear

Engineering Contradiction:
Improvegrip structure formationVSAvoidmaterial distribution uniformity
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent applies structured surfaces specifically in the crotch area and on the gripping aid, while leaving other areas smooth. This local structuring ensures that material redistribution occurs only where needed to form the grip structure, preventing uneven material distribution in other regions and avoiding hole formation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The structured surfaces are prepared in advance on the molded body before the dipping process. This preliminary structuring guides the material flow during immersion, ensuring that material is distributed evenly and forms the grip structure correctly without creating holes or unevenness.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the entire surface is structured, then material adhesion is improved, but the complexity of the molded body increases

Engineering Contradiction:
Improvematerial adhesionVSAvoidmolded body structuring complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of structuring the entire surface, the patent applies structured surfaces only to specific areas where material adhesion is critical - namely the crotch area and the gripping aid. This selective approach improves material adhesion where needed while avoiding the unnecessary complexity of structuring the entire molded body surface.

Inventive Principle:
Principle #3Local quality

AI summary

The invention relates to a former body for producing a glove, wherein the former body has the geometry of a hand with a substantially cylindrical portion attached thereto and with a gripping aid which is arranged below the little finger or below the thumb on one of the two narrow sides of the hand connecting the palm and the back of the hand, or alternatively on the continuation of one of these narrow sides of the hand in the longitudinal direction of the cylindrical portion attached to the hand, wherein the former body has a region with a textured surface at the attachment point of the gripping aid, which region preferably extends in the direction of the fingers of the hand and has a more pronounced texture than other regions of the former body.
