Male Coupling Filtration Replacement Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing male coupling members for fuel cell vehicles require complex and troublesome operations to replace filtration members, involving complete detachment from the vehicle body and potential hydrogen leaks if reconnection is not proper.
Innovation Solution
A male coupling member design that allows filtration member replacement without detaching from the vehicle body, featuring a detachable inner coupling body that holds the filtration member, enabling easy access and replacement while maintaining attachment to the vehicle body and pipe.

Engineering Contradiction Analysis
1Ease of repair
If the male coupling member is completely detached from the vehicle body to replace the filtration member, then the filtration member can be replaced, but the operation becomes troublesome and complicated
Solution Approach 1:
The male coupling member is divided into separable components: the outer coupling body (secured to vehicle body) and the inner coupling body (containing filtration member). This segmentation allows the inner coupling body to be detached and reattached without removing the outer coupling body from the vehicle body, simplifying filtration member replacement operations.
2Ease of repair
If the male coupling member is completely detached from the vehicle body to replace the filtration member, then the filtration member can be replaced, but hydrogen leakage may occur if reconnection is not proper
Solution Approach 1:
By segmenting the coupling member into outer and inner bodies, the design isolates the filtration member replacement operation to only the inner coupling body. The outer coupling body remains securely connected to the vehicle body with its sealing interfaces intact, eliminating hydrogen leakage risks associated with complete detachment and reconnection.
3Ease of repair
If the filtration member is made detachable from the inner coupling body, then the filtration member can be replaced easily, but the structure becomes more complex
Solution Approach 1:
The design segments the coupling member into outer and inner coupling bodies, where the inner coupling body can be detached from the outer coupling body. This segmentation provides a straightforward detachment mechanism that does not significantly increase structural complexity while enabling easy filtration member replacement.

AI summary
A male coupling member detachably couplable to a female coupling member includes an outer coupling body having a first end inserted and fitted into the female coupling member, a second end opposite to the first end, and a passage extending from the first end to the second end. The male coupling member further includes an inner coupling body disposed coaxially with the outer coupling body at a position closer to the first end, and a filtration member detachably attached to the inner coupling body. The inner coupling body is attachable to and detachable from the outer coupling body from the first end. The filtration member is held in the passage when the inner coupling body is attached to the outer coupling body. The filtration member is detachable when the inner coupling body is detached from the outer coupling body.
