Solution Overview

Problem

Existing devices for testing the integrity of gloves and glove ports in isolators do not adequately assess the connection between the glove and the glove port, leading to false positives and inefficiencies in testing.

Innovation Solution

A device that includes the glove, the sealing between the glove and the glove port, and the sealing between the glove port and the isolator wall within a single integrated test space, using an adaptable housing with a fan as a pressure generating unit and a vacuum port for secure connection, along with a controller for automated testing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the known testing device is used to test glove integrity, then the testing process is simple, but the connection between the glove and the glove port is not tested leading to false positives

Engineering Contradiction:
Improvetesting accuracyVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the glove, glove port connection, and isolator wall sealing into a single integrated inner space for testing. This allows all three components to be tested simultaneously in one operation, eliminating false positives while maintaining reasonable device complexity through the adaptor interface.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adaptor serves as an intermediary component that connects the housing to the isolator wall and enables the formation of the integrated inner space. This mediator allows the testing system to include previously untestable components without requiring complete redesign of the entire testing device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If separate tests are performed for glove sealing and isolator wall sealing, then each test can be optimized, but the total testing time increases

Engineering Contradiction:
Improvetesting efficiencyVSAvoidtesting duration
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent combines multiple sealing tests (glove-to-glove port and glove port-to-isolator wall) into a single integrated test procedure. By pressurizing one unified inner space that encompasses all sealings, the system achieves comprehensive testing in one operation rather than requiring sequential separate tests, thereby improving productivity while reducing total testing time.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the housing is designed for a specific glove port size, then the device can be optimized for that size, but it cannot test other sizes leading to increased idle time

Engineering Contradiction:
Improveglove port compatibilityVSAvoiddevice idle time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent segments the connection interface by introducing a removable adaptor that interfaces between the housing and the isolator wall. This allows the main housing to remain standardized while different adaptors can be attached to accommodate various glove port sizes and configurations, enabling the device to test multiple sizes without requiring complete housing redesign or increasing idle time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The housing is designed with universal compatibility through the adaptor interface, allowing a single housing design to work with multiple glove port sizes and types. The adaptor acts as the variable component that adapts the universal housing to specific applications, thereby achieving multi-functionality and reducing device idle time across different testing scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)
