Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If friction-based propulsion systems are used (wheels, propellers), then the object can be moved effectively, but energy dissipation losses increase and efficiency decreases
Solution Approach 1:
The patent replaces traditional mechanical friction-based propulsion systems with a magnetic field-based propulsion system. The magnetic field generating device creates a magnetic field that interacts with the external magnetic field to produce a reaction force, eliminating the need for mechanical contact and friction, thereby reducing energy dissipation losses while maintaining propulsion effectiveness
2Use of energy by moving object
If mass separation propulsion systems are used (rockets, ion drives), then propulsion force is generated, but energy consumption increases
Solution Approach 1:
The patent substitutes mass separation-based propulsion with magnetic field interaction-based propulsion. Instead of accelerating and ejecting mass (propellant), the system uses a magnetic field generating device to create a magnetic field that interacts with the external magnetic field, producing a reaction force through electromagnetic interaction rather than mass ejection, thereby reducing energy consumption while maintaining propulsion force
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the propulsion system and the external environment. The magnetic field generating device creates a magnetic field that acts as a mediator to interact with the external magnetic field, transferring momentum and generating propulsion force without direct mechanical contact or mass ejection, thus improving energy efficiency
3Object-generated harmful factors
If the magnetic field generating device is aligned parallel or perpendicular to magnetic field lines, then the configuration is simplified, but parasitic turning forces are generated
Solution Approach 1:
The patent applies asymmetric positioning of the magnetic field generating device by inclining its central axis at a specific angle (between 0° and 90°, excluding 45°) relative to the magnetic field lines. This asymmetric configuration prevents the generation of parasitic turning forces that would occur with symmetric parallel or perpendicular alignment, while the control system manages the resulting configuration complexity
4Force
If varying current is supplied to the magnetic field generating device, then propulsion force is generated, but control complexity increases
Solution Approach 1:
The patent employs dynamic control by supplying varying current to the magnetic field generating device. The control system dynamically adjusts the current magnitude and timing to generate the required propulsion force while managing the interaction with the external magnetic field. This dynamic approach enables force generation but increases control system complexity
Solution Approach 2:
The patent utilizes periodic action by supplying varying current in controlled cycles to the magnetic field generating device. The current is varied periodically to generate propulsion force through repeated magnetic field interactions, and the control system manages this periodic operation to achieve desired propulsion while handling the associated control complexity
