Engineering Contradiction Analysis
1Force
If conventional propulsion methods using rotating components (propellers, wheels) are employed, then thrust generation is achieved through fluid momentum transfer, but energy loss increases due to turbulence, vibration, and mechanical friction
Solution Approach 1:
The patent replaces mechanical rotating propulsion systems with an electromagnetic field-based propulsion mechanism. The system uses electromagnetic forces acting on conductive elements to generate unidirectional thrust without mechanical rotation, thereby eliminating energy losses associated with turbulence, vibration, and mechanical friction while maintaining effective thrust generation
Solution Approach 2:
The patent extracts and eliminates the rotating components (propellers, wheels) from the propulsion system, retaining only the essential thrust generation function through electromagnetic field interaction with conductive elements in the fluid medium
2Adaptability or versatility
If linear actuators or magnetic levitation systems are used, then propulsion capability is achieved, but device complexity increases due to requirement of three-phase AC inverters and high-frequency electronics
Solution Approach 1:
The patent replaces complex electrical control systems (three-phase AC inverters, variable frequency drives) with a simpler electromagnetic propulsion mechanism that uses direct electromagnetic field interaction to achieve propulsion, thereby maintaining versatility while significantly reducing device complexity
Solution Approach 2:
The patent removes the requirement for complex inverter systems and high-frequency electronics, retaining only the essential electromagnetic field generation and control components needed for propulsion capability
3Force
If superconducting magnets are employed to compensate for magnetic field strength drop across air gap, then magnetic field strength is sufficient, but device complexity and cost increase significantly
Solution Approach 1:
The patent eliminates the air gap between magnetic components by using direct contact or minimal separation, thereby removing the need for superconducting magnets to compensate for field strength drop, and achieving sufficient magnetic field strength with conventional magnet materials
Solution Approach 2:
The patent changes the separation distance parameter between magnetic components from a significant air gap to minimal or zero separation, which fundamentally alters the magnetic field interaction and eliminates the need for high-performance superconducting magnets
