Closed-Loop Support Wire for Cryogenic Tank Motion Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cryogenic liquid storage apparatuses face challenges in ensuring structural rigidity, improving safety and reliability, and minimizing heat penetration, particularly due to ineffective prevention of inner container movement relative to the outer container and complex structures that increase manufacturing costs.
Innovation Solution
A cryogenic liquid storage apparatus featuring a single support wire with a closed-loop shape that connects the inner and outer holders, effectively preventing all six degrees of freedom movements of the inner container relative to the outer container, while simplifying the structure and manufacturing process and reducing heat transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple support members are disposed between the outer container and the inner container to prevent movement, then structural rigidity is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
Multiple separate support members are merged into a single integrated support structure with a closed-loop configuration. This single support structure combines the functions of multiple individual supports while reducing overall complexity and manufacturing cost, directly resolving the contradiction between achieving sufficient structural rigidity and simplifying the device design
Solution Approach 2:
The single support structure is divided into multiple segments or sections that form a closed-loop configuration. This segmentation allows the structure to provide multi-directional support and maintain rigidity while being manufactured as a single integrated piece, resolving the contradiction between structural requirements and manufacturing simplicity
2Reliability
If multiple support members are used to restrain inner container movement, then reliability is improved, but manufacturing efficiency deteriorates
Solution Approach 1:
Multiple support members are merged into a single integrated support structure that can be manufactured in one process. This eliminates the need to manufacture and assemble multiple separate components, improving manufacturing efficiency while maintaining the reliability benefits of having multiple support points through the closed-loop design
3Strength
If support members with high structural strength are used, then structural rigidity is improved, but heat penetration increases
Solution Approach 1:
The support structure is made from composite materials or materials with specific thermal properties that provide high structural strength while maintaining low thermal conductivity. This allows the support to restrain container movement effectively while minimizing heat transfer from the outer container to the inner container, resolving the contradiction between mechanical strength and thermal insulation

AI summary
A cryogenic liquid storage apparatus includes an inner container configured to store a cryogenic liquid, an inner holder disposed at the inner container, an outer container that surrounds the inner container, an outer holder disposed at the outer container, and a support wire that is a single body defining a closed-loop shape passing through the outer holder and the inner holder. The support wire is configured to support the inner container with respect to the outer container.
