Multilayer Disposable Gloves With Segmented Palm Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disposable plastic gloves often lack sufficient durability and visibility of wear, particularly on the palm side where they are subject to more wear and tear, and do not efficiently utilize materials by requiring molding or forming processes.
Innovation Solution
A method of forming a multilayer disposable glove from individual layers of film, where at least three layers are stacked and sealed along a hand-shaped outline, with the palm side having two layers and the back side having one or more layers, allowing for efficient material usage and visibility of wear through different materials or colors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional single-layer or two-layer molding processes are used, then manufacturing simplicity is maintained, but durability and visibility of wear on the palm side are insufficient
Solution Approach 1:
The glove is divided into distinct functional layers: a palm side with multiple layers (including a first layer and second layer) for durability, and a back side with one or more layers for visibility of wear. This segmentation allows each layer to be optimized for its specific function while maintaining overall glove performance.
Solution Approach 2:
Different regions of the glove have different layer configurations tailored to their specific needs. The palm side, which experiences more wear and tear, is equipped with multiple layers including a first layer and second layer for enhanced durability. The back side uses one or more layers primarily for visibility of wear, optimizing material usage and performance in each local area.
2Loss of substance
If molding or forming processes are used to create gloves, then glove shape is achieved, but material usage efficiency decreases
Solution Approach 1:
Individual layers are prepared and stacked in the desired configuration before the sealing process. The layers are arranged with the palm side having a first layer and second layer, and the back side having one or more layers, then sealed together along a hand-shaped outline. This preliminary arrangement optimizes material usage by ensuring each layer is positioned correctly before sealing, eliminating the need for extensive molding or forming operations.
3Reliability
If uniform layering is applied throughout the glove, then manufacturing simplicity is maintained, but visibility of wear and durability on the palm side are compromised
Solution Approach 1:
The glove employs non-uniform layering where the palm side has a first layer and second layer for durability and visibility of wear, while the back side has one or more layers. This local differentiation ensures that the palm side, which is subject to more wear and tear, has enhanced durability and visibility features, while the back side uses simpler construction, optimizing both reliability and material usage.

AI summary
A method of making a multilayer disposable glove from individual layers of film. The method includes providing at least three individual layers of film and arranging the at least three individual layers of film into a stack. The stack includes a first stack portion that has at least two of the individual layers and a second stack portion that has at least one of the individual layers. The method also includes sealing the first and second portions together along a hand-shaped outline. The method also includes cutting the sealed stack along the hand-shaped outline so the seal remains intact, thereby forming the multilayer glove.
