Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional resistive magnetizers are used to magnetize permanent magnets, then the magnetizing function is achieved, but excessive power supply requirements and complex thermal management are required
Solution Approach 1:
The patent changes the operating temperature parameter by cooling the magnetizer to cryogenic temperatures (below 77K), which transforms the resistive magnetizer into a superconducting magnetizer. This parameter change eliminates electrical resistance, thereby removing power supply requirements and simplifying thermal management while maintaining the magnetizing function.
Solution Approach 2:
The patent substitutes the resistive heating mechanism with a superconducting mechanism. By replacing the conventional resistive system with a superconducting system, the harmful thermal effects are eliminated, and the magnetizer operates without continuous power supply, thus resolving the contradiction between power requirements and thermal management complexity.
2Temperature
If conventional resistive magnetizers operate continuously, then magnetizing action is maintained, but excessive thermal management requirements arise
Solution Approach 1:
The patent changes the temperature parameter to cryogenic levels, which fundamentally alters the thermal behavior of the system. At these temperatures, the superconducting material exhibits zero resistance, eliminating continuous thermal management requirements while maintaining or enhancing magnetizing efficiency through sustained magnetic field generation.
Solution Approach 2:
The superconducting magnetizer enables continuous operation without the thermal limitations of resistive systems. The superconducting state allows the magnetizer to maintain its magnetic field continuously without generating excessive heat, thus achieving both continuous productivity and reduced thermal management requirements.
3Use of energy by moving object
If superconducting magnet is cooled below critical temperature, then electrical resistance is lost and power supply requirements are reduced, but cooling infrastructure is required
Solution Approach 1:
The superconducting magnetizer system is designed to be self-cooling through its own operational characteristics. The system uses the heat extracted during magnetizing operations and the inherent thermal properties of superconducting materials to maintain its cryogenic state, reducing the need for external active cooling infrastructure while maintaining low energy consumption.
