Hydrogen Storage Tank Insert Part With Grippable Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydrogen storage systems for fuel cell vehicles require extra components, such as hydrogen storage tank cases, which complicate the replacement process.
Innovation Solution
A hydrogen storage apparatus with integrated hydrogen storage tank insert parts and grippable handles allows for simple replacement of hydrogen storage tanks without additional parts, using a coupling mechanism between the hydrogen inflow and outflow parts for efficient hydrogen supply to the fuel cell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hydrogen storage tank case is used to hold the hydrogen storage tank, then the hydrogen storage tank can be securely held and replaced, but the system complexity increases due to the extra component
Solution Approach 1:
The patent integrates the holding function directly into the hydrogen storage tank insert part by forming a coupling part that couples with the fuel cell's coupling part. This merging of the holding mechanism into the insert part itself eliminates the need for a separate hydrogen storage tank case, thereby reducing system complexity while maintaining secure holding capability through the coupling mechanism.
2Ease of operation
If a hydrogen storage tank case is used for tank replacement, then the tank can be held during replacement, but the replacement process becomes more complex requiring additional parts
Solution Approach 1:
The patent extracts the holding function from the separate hydrogen storage tank case and integrates it directly into the hydrogen storage tank insert part through the coupling part. This allows the insert part itself to hold and guide the hydrogen storage tank during replacement operations, eliminating the need for the extra case component and simplifying the replacement process.
3Reliability
If the hydrogen inflow part is formed in a deep portion of the insert part, then coupling with the fuel cell is improved, but the insert part structure becomes more complex
Solution Approach 1:
The patent merges the hydrogen inflow part formation directly into the insert part structure by forming it in a deep portion of the insert part. This integrated approach allows the insert part to provide both the coupling interface and the hydrogen flow path, eliminating the need for separate components and reducing overall system complexity while improving coupling reliability with the fuel cell.

AI summary
A hydrogen storage apparatus of a vehicle driven by a fuel cell comprising hydrogen storage tank holding apparatuses 8, 9 having pluralities of hydrogen storage tank insert parts 10. When the replaceable hydrogen storage tank 20 is inserted into the hydrogen storage tank insert part 10, the hydrogen outflow part 28 of the hydrogen storage tank 20 is coupled with the hydrogen inflow part 23 connected to the fuel cell 40. The grippable handle 24 is formed at the end portion of the hydrogen storage tank 20. A work of inserting the hydrogen storage tank 20 into the hydrogen storage tank insert part 10 and a work of coupling the hydrogen inflow part 23 and the hydrogen outflow part 28 is performed by gripping the handle 24.
