Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a vacuum thermal insulating structure is used, then thermal insulation performance is improved, but manufacturing complexity increases and reliability decreases due to vacuum maintenance requirements
Solution Approach 1:
The patent replaces the vacuum environment with an inert atmospheric environment filled with thermal insulating material (such as air, nitrogen, or other gases). This eliminates the need to maintain vacuum conditions while still providing effective thermal insulation. The insulating material fills the space between inner and outer containers, creating a stable, maintenance-free insulating barrier that prevents thermal insulating failures associated with vacuum breakdown.
Solution Approach 2:
The patent uses simple, inexpensive thermal insulating materials (such as foam, fiber, or gas-filled layers) that can be easily manufactured and installed without complex vacuum sealing requirements. These materials provide sufficient insulation performance for the application lifecycle without requiring expensive vacuum maintenance infrastructure, making the system more reliable and cost-effective.
2Loss of energy
If a vacuum thermal insulating structure is used, then thermal insulation performance is improved, but device complexity increases due to welding requirements
Solution Approach 1:
The patent divides the container into separate inner and outer containers with thermal insulating material placed between them. This segmented structure eliminates the need for complex welded joints required in vacuum insulation, as each container can be manufactured and assembled independently using simpler joining methods such as mechanical fastening or adhesive bonding.
Solution Approach 2:
The thermal insulating material acts as an intermediary substance between the inner and outer containers, providing thermal insulation without requiring direct contact or welded joints between the containers. This intermediary layer simplifies the manufacturing process by allowing separate assembly of container components and eliminating complex sealing requirements.
3Loss of energy
If a vacuum thermal insulating structure is used, then thermal insulation performance is improved, but ease of manufacture decreases
Solution Approach 1:
The patent changes the physical parameter of the insulating environment from vacuum (zero pressure) to atmospheric pressure filled with insulating material. This parameter change fundamentally simplifies manufacturing, as it eliminates the need for vacuum pumping, sealing, and maintenance systems, allowing for easier assembly and manufacturing using conventional industrial processes.
