Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If superconducting tapes are stacked and shaped into coils using conventional methods, then the coil structure can be formed, but the production cost increases and production time extends due to the complexity of shaping and stacking operations
Solution Approach 1:
The patent replaces mechanical stacking and shaping operations with a direct deposition process where superconducting material is deposited onto a mandrel in the desired coil configuration. This eliminates the need for separate stacking and shaping steps, reducing both production time and operational complexity while maintaining coil structural integrity.
Solution Approach 2:
The patent performs preliminary shaping by depositing the superconducting material directly onto a mandrel that defines the final coil geometry. This preliminary action eliminates the need for subsequent shaping operations, as the coil structure is formed during the deposition process itself, thereby reducing overall manufacturing complexity.
2Adaptability or versatility
If superconducting tapes are cut, twisted, and stacked to achieve special magnetic field configurations, then the desired field configuration is obtained, but the design and construction time increases significantly
Solution Approach 1:
The patent enables dynamic configuration of superconducting coils by allowing the deposition process to adapt to different mandrel geometries. This dynamic approach permits rapid reconfiguration for different magnetic field requirements without time-consuming manual shaping operations, as the coil structure is formed directly in the desired configuration during deposition.
Solution Approach 2:
The patent changes the geometric parameters of the mandrel to achieve different coil configurations. By varying mandrel shape, size, and orientation, the system can produce coils tailored for specific magnetic field requirements, providing versatility without the time loss associated with post-deposition shaping operations.
3Ease of manufacture
If rectangular superconducting tapes are used in conventional stacking methods, then the manufacturing process is straightforward, but the shape and size of the final coil are restricted
Solution Approach 1:
The patent transitions from two-dimensional rectangular tape stacking to three-dimensional direct deposition onto a mandrel. This dimensional change allows the superconducting material to conform to complex coil geometries in all spatial dimensions, eliminating shape restrictions while maintaining manufacturing simplicity through the direct deposition process.
Solution Approach 2:
The patent creates a universal manufacturing approach where a single deposition process can produce coils of various shapes and sizes by simply changing the mandrel geometry. This multi-functional capability eliminates the need for different manufacturing methods for different coil configurations, providing both simplicity and versatility.
