Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the power supply part of the refrigerator rotates with the superconducting motor, then the cooling function is provided during rotation, but the structure becomes complex due to rotating power supply components
Solution Approach 1:
The refrigerator is divided into two independent stators: the compressor outer stator connected to the superconducting stator (stationary) and the compressor inner stator connected to the superconducting rotor (rotating). This segmentation allows the power supply part to remain stationary while the cooling function is still provided during rotation.
Solution Approach 2:
The power supply part (compressor outer stator) is extracted from the rotating assembly and fixedly connected to the superconducting stator. This removes the complexity of rotating power supply components while maintaining the cooling function through the refrigeration assembly connected to the rotating superconducting rotor.
2Adaptability or versatility
If the power supply part rotates with the refrigerator, then the refrigerator can be integrated into the superconducting motor, but mechanical wear and instability occur
Solution Approach 1:
The dual stator configuration separates the power supply function (outer stator) from the rotating cooling function (inner stator). The outer stator is fixedly connected to the superconducting stator and does not rotate, eliminating mechanical wear and instability while the inner stator rotates with the superconducting rotor to provide integrated cooling.
3Reliability
If a traditional rotating refrigerator design is used, then the cooling function is provided, but the structure is complex and maintenance is difficult
Solution Approach 1:
The refrigerator structure is segmented into a stationary outer stator and a rotating inner stator. The outer stator is fixedly connected to the superconducting stator and contains the power supply components, making the structure simpler and easier to manufacture while eliminating the complexity of rotating power supply connections.
Solution Approach 2:
The power supply components are extracted from the rotating assembly and placed in the stationary outer stator. This simplifies the overall structure, making the refrigerator easier to manufacture and maintain while the rotating inner stator provides the cooling function through its connection to the superconducting rotor.
