Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thick metallic materials are used for the inner container and outer container, then the structural strength is improved, but the weight of the container increases
Solution Approach 1:
The patent employs thin-walled metallic containers (inner container 4 and outer container 2) instead of thick-walled structures. The thin-walled design reduces weight while maintaining structural integrity through optimized wall thickness and geometric configuration. This directly addresses the contradiction by achieving sufficient strength with minimal material mass.
Solution Approach 2:
The patent uses composite structural configuration combining thin-walled metallic containers with vacuum insulation and thin-walled support pipes. This composite approach allows each component to be optimized independently - the thin metallic walls provide structural function while the vacuum space provides thermal insulation function, achieving both strength and weight reduction goals.
2Stability of the object's composition
If thick metallic materials and complex configurations are used, then the structural stability is improved, but the heat insulation performance deteriorates
Solution Approach 1:
The patent extracts the insulation function from the structural walls by creating a vacuum space between the inner container 4 and outer container 2. This separation allows the thin-walled containers to maintain structural stability while the vacuum space provides superior thermal insulation, eliminating heat conduction through the container walls.
Solution Approach 2:
The vacuum space acts as an intermediary layer between the inner container 4 and outer container 2, mediating the thermal interaction by eliminating conductive and convective heat transfer. This intermediary vacuum layer enables both thin-walled construction and effective heat insulation to coexist.
3Force
If conventional support structures are used to connect the inner container and outer container, then the mechanical support is improved, but the heat conduction increases
Solution Approach 1:
The patent employs thin-walled pipes (6, 7) as support structures to connect the inner container 4 and outer container 2. These thin-walled pipes provide necessary mechanical support while minimizing thermal conduction due to their reduced cross-sectional area and optimized material selection, directly addressing the heat conduction issue.
Solution Approach 2:
The support pipes are strategically positioned and designed with local optimization - using thin-walled construction only where mechanical support is needed, while maintaining vacuum insulation in the majority of the space between containers. This local quality approach minimizes heat conduction paths while preserving structural support functionality.
4Weight of stationary object
If thin-walled pipes are used to support the inner container, then the weight is reduced, but the structural strength deteriorates
Solution Approach 1:
The thin-walled pipes (6, 7) are designed with optimized wall thickness that provides sufficient structural strength for supporting the inner container 4 while minimizing weight. The thin-walled construction achieves the optimal balance between support strength and weight reduction by using the minimum necessary material thickness.
Solution Approach 2:
The support system uses a composite configuration of thin-walled pipes made from materials with favorable strength-to-weight ratios. The pipes are designed as part of the overall composite structure including the vacuum space, allowing the thin-walled pipes to achieve adequate support strength through geometric optimization and material selection.

AI summary
The metallic sealed double container of the present invention includes an outer container, an inner container, an outer lid for the outer container, and an inner lid for the inner container, all of which being formed from thin metallic sheet. Connection holes are formed in the outer lid and the inner lid by burring, and both end parts of thin-walled pipes are respectively connected while inserted in the connection holes. The inner lid is joined to the inner container, and the outer lid is joined to the outer container, thereby constituting a metallic sealed double container in which the inner container is isolated in the outer container. As a result, the weight of the metallic sealed double container is reduced, the temperature in the inner container can be maintained over long periods of time, and the heat-insulating effect of the resulting sealed double container is high.
