Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If superconducting wires are soldered together using superconducting solder, then connection between superconducting wires is achieved, but filaments of superconducting materials may float and come into contact with air to oxidize, deteriorating connection characteristics
Solution Approach 1:
The patent applies the inert atmosphere principle by filling the container with an inert gas (such as nitrogen or argon) to create a protective environment that prevents oxygen from contacting the superconducting filaments. This eliminates the harmful oxidation effect while maintaining the soldering connection process, thus resolving the contradiction between achieving reliable connections and preventing filament oxidation.
Solution Approach 2:
The patent introduces a protective coating or barrier layer as an intermediary between the superconducting filaments and the air environment. This intermediary layer physically separates the filaments from oxygen, preventing direct contact and oxidation, while allowing the soldering process to proceed effectively. This resolves the contradiction by adding a protective medium that eliminates the harmful effect.
2Object-affected harmful factors
If superconducting filaments are sealed in a container, then oxidation is prevented, but cooling efficiency may be reduced due to poor thermal contact
Solution Approach 1:
The patent applies preliminary action by pre-coating the superconducting filaments with a thermally conductive material before sealing them in the container. This preliminary coating ensures optimal thermal contact between the filaments and the container walls, maintaining high cooling efficiency while the container provides oxidation protection. The thermal coating is applied in advance to eliminate potential thermal resistance issues.
Solution Approach 2:
The patent uses composite materials by combining the superconducting filament material with a thermally conductive coating material. This composite structure maintains the superconducting properties of the filament while adding thermal conductivity to improve heat transfer to the container walls. The composite material resolves the contradiction between protection and cooling efficiency by integrating both requirements into a single optimized structure.
