Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single permanent magnet member and a single electromotive coil member are arranged concentrically, then the structure is simple, but the magnetic force cannot be changed efficiently to improve power generation
Solution Approach 1:
The single permanent magnet member is divided into two separate permanent magnet members (first and second permanent magnet members) arranged concentrically. This segmentation allows independent control of each magnet member's rotation, enabling flexible adjustment of magnetic force characteristics to improve power generation efficiency while maintaining structural simplicity.
Solution Approach 2:
The patent introduces dynamic control by enabling independent rotation of the first and second permanent magnet members. By controlling the rotation speeds and directions of each magnet member separately, the magnetic force acting on the electromotive coil can be dynamically adjusted, allowing optimization of power generation under different operating conditions.
2Adaptability or versatility
If an electromagnet is added separately from the permanent magnet to change magnetic force, then the magnetic force can be adjusted, but the device complexity increases
Solution Approach 1:
The two permanent magnet members serve multiple functions: they generate the primary magnetic field, enable magnetic force adjustment through differential rotation, and provide structural support. This multi-functionality eliminates the need for separate electromagnets while achieving magnetic force control, thereby avoiding increased device complexity.
Solution Approach 2:
The system uses the permanent magnet members themselves to perform the magnetic force adjustment function that would otherwise require a separate electromagnet. By rotating the permanent magnet members at different speeds and directions, the system self-regulates the magnetic force without needing additional active components.

Function Achieved in This Case
The cooperative magnetic force change between the two permanent magnet members increases power generation efficiency by alternating magnetic forces, leading to more reliable and efficient power induction in the electromotive coil.

AI summary
The present invention provides a power generator which can obtain efficient power generation by changing magnetic force acting on electromotive coils. The power generator is provided with a first permanent magnet member 1, a second permanent magnet member 2, and an electromotive coil member 3 arranged concentrically to have a telescoping structure and is configured so that power generation in the electromotive coil member 3 is induced by rotating the first permanent magnet member 1 or/and the second permanent magnet member 2. In the power generator, the first and second permanent magnet members 1 and 2 cooperate with each other to change the magnetic force and, thus, to obtain efficient power generation.
