Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vapor deposition is used to connect superconducting wire materials, then the superconducting layer is protected from damage, but large equipment cannot be transported to the connection site
Solution Approach 1:
The patent extracts the superconducting layer removal function to a specific location (concave section) rather than treating the entire wire. By removing the superconducting layer only at the end portions where connection is needed, the invention enables subsequent connection operations without requiring large vapor deposition equipment at the connection site, thus resolving the portability issue while maintaining superconducting performance in the connected regions.
Solution Approach 2:
The patent performs preliminary removal of the superconducting layer at the end portions before connection. This preliminary action creates concave sections that facilitate direct connection of the wire materials without requiring complex vapor deposition equipment during the actual connection process, thereby solving the equipment portability problem while ensuring reliable electrical connection.
2Stability of the object's composition
If laser cutting is used to cut superconducting wire material, then the cutting face is fused and peeling is prevented, but large equipment cannot be transported to the connection site
Solution Approach 1:
The patent extracts the layer removal function to specific concave sections at the wire ends rather than requiring full-length laser cutting. This localized approach prevents peeling at the connection interfaces while avoiding the need to transport large laser cutting equipment to the connection site, thus resolving the portability contradiction.
Solution Approach 2:
The patent performs preliminary removal of the superconducting layer at the end portions to create concave sections before connection. This preliminary action prevents peeling during connection without requiring large laser equipment at the connection site, thereby maintaining layer integrity while improving equipment portability.
3Ease of operation
If conventional cutting tools are used to cut superconducting wire material, then equipment is portable, but the superconducting layer peels and performance deteriorates
Solution Approach 1:
The patent extracts the layer removal function to specific concave sections at the wire ends using portable means, rather than requiring full-length cutting that causes peeling. This localized removal prevents peeling at connection interfaces while maintaining the portability advantage of using smaller equipment at the connection site.
Solution Approach 2:
The patent performs preliminary removal of the superconducting layer at the end portions to create concave sections before connection. This preliminary action prevents peeling during connection operations and maintains superconducting performance, while allowing the use of portable equipment rather than requiring large fixed installation equipment.
