High-Pressure Container Reinforcing Member Axial Load Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing high-pressure container units face a trade-off between collision resistance performance and capacity, as reinforcing members are typically added to reduce the diameter of the container main bodies, compromising their capacity.
Innovation Solution
A high-pressure container unit design featuring a box-shaped case with cylindrical container main bodies and reinforcing members extending along the axial direction, positioned between container main bodies and the case's bottom and ceiling, allowing for improved collision resistance without reducing the container's diameter by utilizing dead spaces and connecting members to disperse collision loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a reinforcing member is disposed in the case to improve collision resistance performance, then collision resistance is improved, but the capacity of the high-pressure tank must be reduced
Solution Approach 1:
The reinforcing member is positioned in the axial direction (along the length of the container) rather than radially (across the diameter). This dimensional change allows the reinforcing member to be placed in the dead space between adjacent containers and the case walls, preventing interference with the container diameter and thus maintaining capacity while still providing collision resistance through load transmission along the axial direction
2Strength
If the diameter of the container main body is reduced to accommodate reinforcing members, then collision resistance is improved, but the capacity is reduced
Solution Approach 1:
The reinforcing structure utilizes the axial dimension (length) of the container rather than the radial dimension (diameter). By placing reinforcing members in the axial direction within the dead space, the design achieves collision resistance without compromising the container's diameter and thus its capacity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances collision resistance performance while maintaining the capacity of the high-pressure container unit, particularly during side collisions, by effectively transmitting and dispersing collision loads between reinforcing members without reducing the container's diameter.
Implementation Method 1
An external force such as a collision load input to one side in the axial direction of the container main body can be transmitted to the other side in the axial direction
Implementation Method 2
a collision load can be dispersed between the lower reinforcing member and the upper reinforcing member
