Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the number of gears transmitted to the rotor is increased to assist rotation, then the rotational speed may be increased, but the rotational force becomes weaker and power generation efficiency drops
Solution Approach 1:
The generator is divided into two independent rotor systems: an outer rotor with permanent magnets for power generation and an inner rotor with magnets for providing rotational force. This segmentation allows each rotor to perform its specific function optimally without interfering with the other, resolving the contradiction between rotational speed and rotational force.
Solution Approach 2:
The inner rotor is nested within the outer rotor, with the inner rotor's rotation axis positioned between the outer rotor's rotation axis and the outer rotor itself. This nested configuration allows the inner rotor to provide rotational force through magnetic interaction while the outer rotor generates electricity, enabling both speed and force to be maintained simultaneously.
2Ease of operation
If multiple gears are used to transmit rotational force to the rotor, then the rotor can be rotated, but the time for rotating the rotor increases and power generation efficiency significantly drops
Solution Approach 1:
The patent replaces the traditional mechanical gear transmission system with a magnetic interaction system. The inner rotor's magnets interact with the outer rotor's permanent magnets to directly provide rotational force, eliminating the need for multiple gears and significantly reducing the time required to rotate the rotor while maintaining ease of operation.
3Productivity
If permanent magnets are used to assist rotation and gears are utilized, then the number of rotations may be increased, but the rotational force is weak and the time to generate electricity is short
Solution Approach 1:
The generator is divided into two independent rotor systems: an outer rotor with permanent magnets for power generation and an inner rotor with magnets for providing rotational force. This segmentation allows each rotor to perform its specific function optimally without interfering with the other, resolving the contradiction between rotational speed and rotational force.
Solution Approach 2:
The inner rotor acts as an intermediary that provides rotational force through magnetic interaction with the outer rotor. This intermediary mechanism enables the system to achieve high rotational speed while maintaining sufficient rotational force, as the inner rotor's magnetic field serves as the mediator between the driving force and the power generation process.
