Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas storage canisters with metal hydride materials face issues of non-uniform heating and potential leakage due to thermal expansion, leading to inefficient hydrogen gas release and impaired performance.
Innovation Solution
A gas storage canister with a compartment structure and lattice design, featuring multiple housings and a gas guide rod, where gas storage material is locally accommodated within compartments defined by partition plates, allowing for uniform heating and enhanced structural strength to prevent deformation and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the gas storage material is accommodated within a single receptacle of the canister body, then the structure is simple, but the gas storage material fails to be uniformly and stably heated when the volume is too large
Solution Approach 1:
The single receptacle is divided into multiple compartments using partition plates, creating a compartment structure. This segmentation allows each compartment to be heated more uniformly while maintaining overall structural organization. The partition plates create separate spaces that facilitate better heat distribution throughout the gas storage material.
2Quantity of substance
If the gas storage material volume is increased, then the storage capacity is improved, but the gas storage material fails to be uniformly heated and thermal expansion causes deformation
Solution Approach 1:
By dividing the large volume into multiple smaller compartments, each compartment can be heated more uniformly despite the overall increased storage capacity. The segmentation prevents the heating instability that would occur in a single large receptacle.
Solution Approach 2:
The partition plates create localized compartments where heat can be more effectively distributed. Each local compartment experiences more uniform heating conditions compared to a single large space, thereby improving overall heating stability while maintaining high storage capacity.
3Temperature
If partition articles are used to divide the gas storage material, then heating uniformity is improved, but thermal expansion results in deformation of the partition articles
Solution Approach 1:
The partition plates are constructed using composite materials that combine high strength with thermal stability. This allows the partition structure to maintain its integrity during thermal expansion and contraction cycles while still achieving uniform heating of the gas storage material in each compartment.
4Temperature
If the gas storage material is divided into multiple compartments, then heating uniformity is improved, but the device complexity increases
Solution Approach 1:
The receptacle is segmented into multiple compartments using partition plates, which achieves uniform heating while maintaining a relatively simple overall structure. The segmentation is implemented in a straightforward manner that does not excessively increase device complexity.
Solution Approach 2:
The partition plates serve multiple functions: they divide the receptacle into compartments for uniform heating, provides structural support, and prevent gas storage material leakage. This multi-functionality reduces the need for additional components, thereby limiting the increase in device complexity.
