Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional generator is used for natural energy conversion, then it can generate sufficient electricity for large-scale machinery, but it becomes too large for applications like bicycles and small household appliances
Solution Approach 1:
The generator is divided into two separate units: a drive unit for generating mechanical rotation and a generating unit for converting mechanical energy to electrical energy. This segmentation allows each unit to be optimized independently, reducing the overall size while maintaining power generation capability for small-scale applications
Solution Approach 2:
The permanent magnet assembly is nested within the drive rotor, and the drive rotor is positioned within the drive stator. This nested configuration maximizes space utilization and reduces the overall generator size while maintaining sufficient power generation capacity
2Productivity
If a conventional generator structure is used, then it can be assembled, but the rotating shaft does not rotate smoothly, resulting in poor generating efficiency
Solution Approach 1:
The mechanical contact between the rotating shaft and bearing is replaced with a magnetic bearing system using permanent magnets. The magnetic field provides non-contact support, eliminating mechanical friction and enabling smooth rotation, which directly improves generating efficiency
Solution Approach 2:
The invention changes the support mechanism parameter from mechanical contact to magnetic field interaction. This parameter change transforms the friction-based mechanical system into a frictionless magnetic levitation system, achieving smooth rotation and enhanced generating efficiency
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device achieves high-efficiency electricity generation with smooth rotation of the shaft, resulting in improved voltage, current, and frequency output, while also recycling excess electricity and enhancing heat dissipation through arc-shaped holes in the housing.
Implementation Method 1
Through the magnetic levitation effect between the first permanent magnets and the first auxiliary magnet, the rotating shaft can generate a corresponding rotation and the rotating shaft can be rotated more smoothly to enhance generating efficiency
Implementation Method 2
The corresponding surfaces of the first permanent magnets and the first auxiliary magnet have the same magnetic pole and therefore have a repulsive force
