High-Pressure Tank Holding Frame for Torsion-Resistant Vehicle Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment methods for high-pressure storage tanks on vehicles, such as loops or metal retaining straps, are not torsion-resistant, leading to potential deformation and unsafe holding during accidents, especially for commercial vehicles that require large fuel storage systems.
Innovation Solution
A holding frame with a base structure attached to the vehicle chassis and a support device comprising shell elements that encircle the high-pressure storage tanks, transferring forces directly to the chassis and minimizing torsion, while allowing for secure attachment and weight optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If loops or metal retaining straps are used to attach high-pressure storage tanks, then the attachment device is simple in structure, but the torsion resistance is insufficient and the holding security is compromised during accidents
Solution Approach 1:
The holding frame is divided into multiple shell elements (first and second shell elements) spaced apart from each other, with each shell element having receiving portions that encircle the tank. This segmentation provides torsion resistance while maintaining a relatively simple overall structure, as each segment independently contributes to holding security.
Solution Approach 2:
The holding frame uses a composite structure combining multiple shell elements made of metal or composite materials, attached to the vehicle chassis via a base structure. This composite approach enhances torsion resistance and holding security without requiring a completely complex design, as the combination of materials and spatial arrangement provides the necessary strength.
2Reliability
If a robust holding frame is designed to prevent tank deformation during accidents, then the holding security is improved, but the weight of the holding device increases
Solution Approach 1:
By segmenting the holding frame into multiple shell elements that encircle the tank at different locations, the structure achieves high holding security and torsion resistance distributed across multiple points, rather than requiring a single heavy monolithic structure. This allows weight optimization while maintaining reliability.
Solution Approach 2:
The holding frame utilizes the spatial dimension by positioning shell elements at different locations around the tank (first shell element at one location, second shell element at another location), creating a three-dimensional holding system. This dimensional approach provides enhanced holding security without proportionally increasing weight, as the spatial arrangement distributes structural requirements.
