Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional magnetic field interactions are used in conventional motors and generators, then the device structure is simple and easy to manufacture, but energy conversion efficiency is low and energy consumption is high
Solution Approach 1:
The magnetic field system is segmented into multiple independent magnetic tunnels (first magnetic tunnel, second magnetic tunnel, etc.) with distinct magnetic pole arrangements. Each tunnel contains multiple magnetic poles (first magnetic pole, second magnetic pole, third magnetic pole, fourth magnetic pole) that can be independently configured to optimize flux density and torque production in different spatial zones, thereby improving overall energy conversion efficiency while maintaining manageable structural complexity through modular design
Solution Approach 2:
The invention transitions from traditional two-dimensional magnetic field interaction to a three-dimensional multi-tunnel configuration. Multiple magnetic tunnels are arranged in different spatial dimensions around the rotor, creating a more complex but efficient magnetic field distribution that increases torque density and power output without proportionally increasing device volume
2Power
If traditional sinusoidal voltage production is used, then the electrical system is simple, but torque and horsepower output is limited
Solution Approach 1:
Different magnetic poles within each tunnel are configured with specific local characteristics: first and second magnetic poles in the first tunnel have different orientations from third and fourth magnetic poles in the second tunnel. This local differentiation allows optimized flux density distribution in each zone, maximizing torque production capability while maintaining overall system coherence
Solution Approach 2:
The magnetic pole configurations are deliberately asymmetric across different tunnels. The first magnetic tunnel has a different magnetic pole arrangement than the second magnetic tunnel, creating asymmetric magnetic field distributions that enhance torque density and power output by optimizing flux paths in different spatial orientations
3Ease of manufacture
If conventional motor design is used, then manufacturing is straightforward, but energy consumption is high and efficiency is low
Solution Approach 1:
The motor is divided into modular magnetic tunnel segments that can be manufactured separately and assembled. Each tunnel contains a standardized set of magnetic poles that can be produced using conventional manufacturing techniques, maintaining ease of manufacture while the multi-tunnel configuration collectively achieves superior energy efficiency through optimized magnetic field interactions
Solution Approach 2:
Magnetic poles are pre-configured in specific tunnels with predetermined orientations during the manufacturing process. The first magnetic pole, second magnetic pole, third magnetic pole, and fourth magnetic pole are positioned in advance to create optimal flux density distributions, reducing energy losses during operation while maintaining straightforward manufacturing procedures
