Vent Membrane Hermeticity Testing Without Sealing Plug Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for hermeticity testing of electrical devices are prone to human error and inefficiency, especially when testing multiple devices simultaneously, as they require manual intervention and may not ensure proper sealing without removing and reinserting sealing plugs.
Innovation Solution
An apparatus and method for hermeticity testing that uses a vent with a bidirectional membrane, such as Gore-Tex, allowing pressurized air to flow into the enclosure without the need for removing and reinserting a sealing plug, and includes an adapter with a sealing device and cable gland for easy connection and disconnection, enabling both manual and automatic testing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual hermeticity testing is performed by removing and reinserting sealing plugs, then hermeticity can be tested, but human error increases and testing efficiency decreases
Solution Approach 1:
The vent assembly with membrane allows the enclosure to self-regulate pressure and temperature equilibrium without manual intervention for sealing plug removal and reinsertion. The system serves itself by maintaining equilibrium through the membrane's bidirectional air flow capability, eliminating human error while preserving testing reliability.
Solution Approach 2:
The membrane acts as an intermediary between the enclosure interior and exterior, allowing controlled air flow while maintaining hermeticity. This intermediary enables automated testing by mediating pressure equalization without requiring direct human manipulation of sealing components, thus improving both reliability and productivity.
2Reliability
If sealing plugs are removed and reinserted during testing, then hermeticity can be verified, but the risk of improper sealing increases due to human error
Solution Approach 1:
The vent assembly with membrane allows the enclosure to self-regulate pressure and temperature equilibrium without manual intervention for sealing plug removal and reinsertion. The system serves itself by maintaining equilibrium through the membrane's bidirectional air flow capability, eliminating human error while preserving testing reliability.
Solution Approach 2:
The membrane in the vent assembly provides a flexible, thin-film solution that allows bidirectional air flow while maintaining hermetic sealing. This flexible film eliminates the need for rigid sealing plug manipulation, improving ease of operation while ensuring sealing integrity through its inherent flexibility and conformability.
3Reliability
If traditional hermeticity testing methods are used, then testing can be performed, but device disassembly and reassembly are required which increases complexity
Solution Approach 1:
The membrane acts as an intermediary between the enclosure interior and exterior, allowing controlled air flow while maintaining hermeticity. This intermediary enables automated testing by mediating pressure equalization without requiring direct human manipulation of sealing components, thus improving both reliability and productivity.
Solution Approach 2:
The vent assembly serves multiple functions: it maintains thermal equilibrium, enables bidirectional air flow for pressure equalization, and provides a sealed connection point for testing equipment. This multi-functionality eliminates the need for separate disassembly and reassembly steps, reducing procedural complexity while maintaining test validity.
4Reliability
If periodic hermeticity tests are conducted on deployed devices, then maintenance can be performed, but frequent access and disassembly are required
