Multi-Layer Protective Glove with Removable Outer Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gloves used in food preparation and medical applications lack robustness while maintaining sensitivity, leading to potential bacterial transmission and contamination issues due to thinness and the need for frequent replacement, which compromises hygiene.
Innovation Solution
A hygienic glove with multiple removable latex layers that are thin enough for dexterity but can be easily replaced, featuring tabs for easy removal and varying thickness for different applications, providing enhanced durability and sensitivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If disposable gloves are made thin to maintain tactile sensitivity, then sensitivity of touch is improved, but reliability deteriorates due to prone to failure and bacterial transmission
Solution Approach 1:
The glove is divided into multiple separate layers (first layer, second layer, third layer) that can be worn simultaneously. Each layer can be thin enough to maintain tactile sensitivity while the combination of multiple layers provides the reliability and protection of a thicker glove, preventing bacterial transmission and material failure.
2Device complexity
If single-layer gloves are used to maintain simplicity, then device complexity is reduced, but reliability deteriorates due to frequent failure and need for replacement
Solution Approach 1:
The glove system uses multiple independent layers instead of a single thick layer. This segmentation allows each layer to remain simple in structure while the layered configuration as a whole provides enhanced durability and reliability, reducing the frequency of glove failure and replacement needs.
Solution Approach 2:
The glove structure nests multiple layers within each other, with the first layer adjacent to the wearer's hand, the second layer over the first, and the third layer over the second. This nested arrangement maintains relative simplicity in how the glove is put on and worn while providing the reliability benefits of multiple protective barriers.
3Reliability
If thick gloves are used to improve robustness, then reliability is improved, but tactile sensitivity deteriorates due to reduced sensitivity of touch
Solution Approach 1:
Instead of using a single thick glove that would reduce tactile sensitivity, the invention segments the protection into multiple thin layers. Each layer maintains tactile sensitivity by being thin, while the cumulative effect of multiple layers provides the robustness and reliability of a thick glove.
4Quantity of substance
If gloves are frequently replaced to maintain hygiene, then purity is improved, but loss of time increases due to time taken to discard and replace gloves
Solution Approach 1:
The glove system segments the protective function into multiple removable layers. When contamination occurs, only the contaminated outer layers need to be removed and replaced, while inner layers that remain clean can be retained. This reduces the frequency of complete glove replacements and minimizes time loss compared to replacing entire single-layer gloves.

AI summary
A glove having a plurality of discardable layers, the glove including one or more discardable outer layers that have an outer tab at a wrist area configured to facilitate removal of the outer layer; and at least one inner layer that includes an inner tab at the wrist area. The outer tab of each discardable outer layer is positioned to completely cover the tab of the at least one inner layer. The inner tab is recessed relative to the outer tab to provide a grip area on the outer tab that avoids contamination of the inner tab.
