Adjustable Hydrogen Tank Dome Protector for Pressure Vessel Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hydrogen tanks face challenges in impact resistance during transportation due to fixed mounting, and existing protectors fail to accommodate the expansion or contraction of pressure vessels containing hydrogen gas, leading to potential deformation and safety risks.
Innovation Solution
A fluid tank design featuring a pressure vessel with first and second dome protectors connected by a connecting member that allows adjustable distance, enabling the protector to adapt to pressure vessel expansion or contraction, while an exterior resin protector facilitates quick heat transfer to the safety valve during fires.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a fixed protector is placed around the pressure vessel to improve impact resistance, then the impact resistance is improved, but the protector deforms when the pressure vessel expands or contracts due to pressure changes
Solution Approach 1:
The connecting member is designed with movable connections (sliding or rotating) that allow the distance between the first and second dome protectors to change dynamically. This enables the protector structure to adapt to the expansion and contraction of the pressure vessel while maintaining impact protection capability.
2Stability of the object's composition
If the connecting member is made rigid to maintain protector structure, then the structural stability is improved, but the protector cannot accommodate pressure vessel expansion or contraction
Solution Approach 1:
The connecting member incorporates movable connection mechanisms that provide both structural stability and dynamic adaptability. The sliding or rotating connections maintain the protector's structural integrity while allowing distance adjustment to accommodate pressure vessel volume changes.
3Strength
If the exterior resin protector is used for impact protection, then the impact resistance is improved, but heat propagation to the safety valve is delayed during fires
Solution Approach 1:
The exterior resin protector is designed with differentiated local properties: it provides impact protection while incorporating heat transfer pathways or regions that facilitate rapid heat propagation to the safety valve during fire conditions, balancing protective and thermal response functions.
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
The design effectively suppresses deformation of the protector and ensures the pressure vessel's safety by allowing the connecting member to adjust with pressure changes and actively burning the exterior resin protector to quickly operate the safety valve, preventing pressure vessel rupture during fires.
Implementation Method 1
exterior resin protector facilitates quick heat transfer to the safety valve during fires
Implementation Method 2
the pressure vessel expands or contracts as an internal pressure changes

AI summary
The pressure vessel contains a fluid, such as a high pressure gas, therein. The metal dome and the metal dome are arranged in the longitudinal direction of the pressure vessel opposite each other with the pressure vessel interposed therebetween. The stay connects the metal dome and the metal dome. The stay is connected to the metal dome and the metal dome such that the distance between the metal dome and the metal dome can be varied.
