Solution Overview

Problem

Existing methods for dispensing protective gloves often lead to contamination of the gloves and surrounding environment due to improper handling and exposure, failing to effectively prevent the transmission of pathogenic organisms in healthcare and food service settings.

Innovation Solution

A sanitary glove dispensing apparatus that dispenses connected protective gloves by cuff ends, using mechanical or chemical connectors to maintain the gloves in an overlapped pattern, preventing finger end contamination and protecting remaining gloves from the environment and other users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If gloves are dispensed from open boxes using traditional methods, then ease of operation is improved, but contamination of glove surfaces occurs

Engineering Contradiction:

Improveease of glove retrievalVSAvoidglove surface contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the harmful element (contaminated working surface) from the dispensing process by providing a separate clean grasping surface that does not contact the glove during removal, allowing the glove to be pulled off the contaminated surface without contamination

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention introduces an intermediary clean grasping surface that mediates between the user's hand and the glove, allowing the user to grasp the glove indirectly through the clean surface rather than directly touching the glove itself

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If multiple gloves are grasped at once from open boxes, then productivity is improved, but cross-contamination between gloves occurs

Engineering Contradiction:

Improvespeed of glove donningVSAvoidcross-contamination

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The invention segments the glove stack into individual accessible units where each glove can be separately grasped from the clean surface, preventing cross-contamination while still allowing rapid sequential removal of multiple gloves

Inventive Principle:

Principle #1Segmentation

3Device complexity

If open box dispensers are used, then device complexity is reduced, but environmental contamination of gloves occurs

Engineering Contradiction:

Improvesimplicity of dispenser structureVSAvoidenvironmental contamination

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The invention applies local quality by providing a specifically clean grasping surface area within the dispenser that is distinct from the potentially contaminated environment, allowing gloves to be accessed without exposing the entire glove surface to environmental contamination

Inventive Principle:

Principle #3Local quality

AI summary

A sanitary glove dispensing apparatus. The sanitary glove dispensing apparatus, dispenses connected protective gloves overlapped in a pre-determined pattern, by both cuff ends, so that finger ends of the protective gloves are not contaminated during dispensing and protecting remaining protective gloves in the apparatus from surrounding environment and from other users of the apparatus.
