Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual alignment and connection of refueling probes is used, then the system is simpler and requires no special materials, but the process is time-consuming and prone to human error
Solution Approach 1:
The patent replaces manual mechanical alignment with magnetic alignment using an electromagnet and superconductor. The electromagnet generates a magnetic field that interacts with the superconductor to automatically align the refueling probe with the receptacle, eliminating the need for manual mechanical positioning while reducing complexity through automated guidance.
Solution Approach 2:
The patent utilizes the Meissner effect and flux trapping phenomenon by cooling the superconductor below its critical temperature. This parameter change (temperature) enables the superconductor to exhibit perfect diamagnetism, creating a repulsive force that guides and aligns the probe automatically without mechanical intervention.
2Reliability
If manual alignment procedures are used, then training requirements are higher and errors increase, but the equipment and materials required are fewer
Solution Approach 1:
The patent exploits the phase transition of the superconductor when cooled below its critical temperature. This phase transition enables the material to exhibit perfect diamagnetism through the Meissner effect, creating a reliable magnetic field interaction that ensures accurate and consistent alignment, thereby improving connection reliability.
Solution Approach 2:
The magnetic alignment system is self-regulating through the physical properties of the superconductor. The electromagnet generates a magnetic field that automatically guides the probe into correct alignment without requiring external control or manual adjustment, ensuring high connection accuracy while consuming energy only during the alignment phase.
