Cross-Frame Pressure Vessel Support for Space-Efficient Hydrogen Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure vessel support structures in hydrogen vehicles complicate the vehicle design, degrade spatial utilization, and limit the size and traveling distance due to the need for separate support apparatuses, which occupy valuable space and reduce design freedom.
Innovation Solution
A pressure vessel support apparatus utilizing a cross-frame portion that connects and supports side members, allowing the pressure vessel to be mounted between them without additional support structures, with adjustable cross-members to optimize stability and resonance suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate support apparatus is provided to support the pressure vessel in the space between side members, then the pressure vessel can be supported, but the structure becomes complicated and spatial utilization is degraded
Solution Approach 1:
The cross-frame portion is designed to simultaneously perform two functions: supporting the side members and supporting the pressure vessel. By merging these two support functions into a single structural element, the patent eliminates the need for a separate pressure vessel support apparatus, thereby simplifying the overall structure while maintaining reliable support for the pressure vessel.
Solution Approach 2:
The cross-frame portion is designed as a multi-functional component that serves both as a side member support structure and as a pressure vessel support structure. This universal design allows the same structural element to fulfill multiple support roles, improving spatial utilization and reducing structural complexity.
2Reliability
If a separate support apparatus is provided, then the pressure vessel can be supported, but the space for installing the support apparatus needs to be ensured, which degrades spatial utilization
Solution Approach 1:
By combining the side member support function and pressure vessel support function into the single cross-frame portion, the patent eliminates the need for additional space that would be required for a separate support apparatus. The cross-frame portion utilizes the existing space between side members efficiently, thereby improving spatial utilization.
3Reliability
If both the pressure vessel and support apparatus are provided together in the space between side members, then the pressure vessel can be supported, but it becomes difficult to increase the size of the pressure vessel
Solution Approach 1:
The cross-frame portion integrates both support functions, which eliminates the need for a separate support apparatus that would otherwise occupy valuable space. This integration creates additional available volume within the space between side members, allowing the pressure vessel size to be increased for greater hydrogen storage capacity.

AI summary
A pressure vessel support apparatus includes a first side member configured to be coupled to an object, a second side member spaced from the first side member, and a cross-frame portion connecting the first side member and the second side member and supporting a pressure vessel between the first side member and the second side member, obtaining an advantageous effect of simplifying a structure and improving spatial utilization and a degree of design freedom.
