Solution Overview

Problem

Existing methods for donning sterile gloves often increase cost and complexity, failing to minimize contamination risks effectively.

Innovation Solution

A sterile glove design featuring a detachable tab and shield that allows for touchless donning by exposing a portion of the cuff's inside surface as an outer facing surface, enabling the glove to be picked up and manipulated without contacting the wearable portion, thereby reducing contamination risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cuff is folded over to expose the inner surface as an outer facing surface, then the glove can be picked up without touching the wearable portion, but the structure complexity increases

Engineering Contradiction:

Improvecontamination risk minimizationVSAvoidcuff folding structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The cuff is pre-folded over during packaging to expose the inner surface as an outer facing surface, allowing the glove to be picked up without touching the wearable portion. This preliminary action prepares the glove for touchless donning before use.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If detachable tabs and shields are added for touchless donning, then contamination risk is reduced, but manufacturing cost and complexity increase

Engineering Contradiction:

Improvesterile state integrityVSAvoiddetachable components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The detachable tab and shield are separated as independent components from the main glove body, allowing them to be attached temporarily for donning and then removed. This segmentation enables touchless donning functionality while keeping the main glove structure simple.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The tab and shield are designed as detachable components that can be removed after serving their protective function during donning. This extraction allows the glove to maintain simplicity during use while providing enhanced protection during the critical donning phase.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If the cuff is folded over during packaging, then touchless handling is enabled, but the glove requires additional manipulation steps for donning

Engineering Contradiction:

Improvetouchless handlingVSAvoiddonning procedure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The detachable tab serves as an intermediary element that facilitates touchless handling during donning. The user grasps the tab rather than the glove directly, and the tab can be detached after transferring the glove to the sterile field, simplifying the overall procedure.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A sterile glove that includes a hand and finger portion, a cuff having an inside surface and an outside surface, and a cuff rim. The cuff is adapted to be folded over at a fold when the glove is packaged, and a portion of the inside surface of the cuff becomes an outer facing surface when it is folded over. The glove further includes a detachable tab that is coupled to the inside surface and includes a free end and a non-free end. The glove further includes a detachable shield covering at least a portion of the outer facing surface when the cuff is folded over at the fold.
