Energy Storage Housing with External Channel Opening for Leak Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage housings face challenges in preventing leakage from channels, which can lead to fatal failures if not detected early.
Innovation Solution
A housing design featuring a support section with channels that extend through a transition section, where the opening of the channel is outside the housing chamber, allowing for external leakage detection and prevention, and includes sealing elements to ensure fluidic connections are secure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the channel opening is located inside the housing chamber, then the fluid transfer is simplified, but leakage cannot be detected externally leading to fatal failures
Solution Approach 1:
The channel opening is extracted from the housing chamber interior and positioned on the outer side of the first housing element. This allows the opening to be accessible for external leakage detection while the channel remains fluidically connected to the housing chamber through the transfer section, resolving the contradiction between reliability and device complexity.
2Reliability
If a sealing element is added between the connection element and transfer section, then leakage prevention is improved, but device complexity increases
Solution Approach 1:
A sealing element is introduced specifically at the critical interface between the connection element and transfer section where fluid leakage would occur. The sealing element features a sealing surface that contacts the transfer section, providing localized sealing protection without requiring system-wide complexity increases.
3Ease of operation
If the channel opening is moved outside the housing chamber, then leakage detection is enabled, but the path for fluid transfer becomes more complex
Solution Approach 1:
The transfer section acts as an intermediary structure that connects the externally positioned channel opening to the housing chamber interior. This mediator allows fluid to flow from the externally accessible opening through the transfer section into the housing chamber, enabling both leakage detection and fluid transfer without requiring the opening to be inside the chamber.
