Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If intermittent power supply is adopted to capture required magnetic force, then the motor can drive the rotor to rotate, but the coils will generate power during power suspension due to high magnetic flux and high cut count, causing voltage proliferation and energy waste
Solution Approach 1:
The patent applies preliminary action by introducing an induction switch circuit that detects the position of magnetic components before power is supplied to coils. The circuit pre-determines which coils should be activated based on the relative positions of magnetic components, ensuring power is supplied only when necessary and preventing voltage proliferation during power suspension periods. This proactive control mechanism eliminates unnecessary energy consumption while maintaining required output power.
Solution Approach 2:
The patent implements feedback through the induction switch circuit that continuously monitors the positions of magnetic components and provides real-time feedback to control power supply to coils. The circuit detects when magnetic components are in positions that would cause harmful power generation during suspension, and automatically adjusts power supply accordingly. This closed-loop feedback system optimizes energy efficiency while maintaining motor performance.
2Force
If high magnetic flux and high cut count configuration is used, then the motor can generate required magnetic force, but unnecessary power input is needed to suppress internal voltage proliferation, reducing energy conversion efficiency
Solution Approach 1:
The induction switch circuit performs preliminary detection of magnetic component positions before power supply is activated. By knowing the exact positions of magnetic components in advance, the system can selectively power only those coils that will contribute to useful magnetic force generation, preventing unnecessary power input that would otherwise be required to suppress voltage proliferation in coils that would generate harmful back-EMF during suspension.
Solution Approach 2:
The patent replaces the traditional mechanical timing mechanism with an induction-based detection system. Instead of using mechanical switches or timers to control power supply, the invention uses induction switches that detect the magnetic field positions and automatically control power supply timing. This substitution eliminates the need for high input power to suppress voltage proliferation while maintaining the high magnetic flux configuration.
3Device complexity
If ring-type motor structure with single-sided magnetic force is used, then the motor structure is simple, but the output power performance is poor at the same power input
Solution Approach 1:
The patent transitions from a traditional single-sided ring-type motor structure to a multi-layer disc motor structure with magnetic components arranged in multiple dimensions. The first and second magnetic disc sets are positioned on opposite sides of the coil set, creating a multi-dimensional magnetic field configuration. This dimensional change allows the motor to generate magnetic force in multiple directions simultaneously, significantly improving output power performance while maintaining relatively simple construction.
Solution Approach 2:
The patent merges multiple magnetic disc sets (first and second magnetic disc sets) with the coil set in a compact integrated structure. The magnetic components from both disc sets work together with the coil set to generate combined magnetic force, effectively combining the capabilities of multiple magnetic sources into a single integrated motor structure. This merging approach increases output power without proportionally increasing device complexity.
