Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional generators are used to convert mechanical energy into electrical energy, then the basic generation function is achieved, but energy loss increases and efficiency decreases
Solution Approach 1:
The patent implements nested magnetic fields by placing multiple layers of permanent magnets within the generator structure. The inner rotor contains magnets, while the outer stator contains additional magnets, creating concentric magnetic field layers that interact to enhance flux density and improve energy conversion efficiency while reducing losses.
Solution Approach 2:
The patent transitions from conventional single-layer magnetic field generation to multi-layer three-dimensional magnetic field configuration. By adding the outer stator magnets surrounding the inner rotor magnets, the system creates enhanced magnetic flux pathways in multiple spatial dimensions, improving the overall magnetic coupling and energy transfer efficiency.
2Power
If higher power output is achieved in existing generators, then power delivery increases, but operating speed must increase and torque requirements change
Solution Approach 1:
The patent employs composite magnetic structures combining multiple permanent magnet materials in the inner rotor and outer stator. This composite magnetic system creates synergistic magnetic field interactions that amplify the overall magnetic flux, enabling higher power output at reduced operating speeds compared to conventional single-material generator designs.
Solution Approach 2:
The nested configuration of inner rotor magnets and outer stator magnets creates multiple magnetic interaction zones. This nested arrangement multiplies the effective magnetic flux density without proportionally increasing the mechanical input speed, allowing the generator to deliver higher power output at lower rotational speeds.
3Device complexity
If conventional magnetic field configuration is used, then the generator structure is simple, but magnetic flux density is insufficient for high efficiency
Solution Approach 1:
The patent segments the magnetic field generation function into distinct inner rotor magnets and outer stator magnets. This segmentation allows each magnetic component to be independently optimized and positioned to create specific magnetic flux patterns, enhancing overall flux density while maintaining a modular structure that is manageable despite its increased complexity.
Solution Approach 2:
The patent adds a radial dimension to the magnetic field configuration by placing outer stator magnets surrounding the inner rotor magnets. This dimensional expansion creates enhanced magnetic flux pathways through the air gap, significantly increasing magnetic flux density while organizing the complexity into a systematic multi-layer architecture.

Data Source
AI summary
Apparatuses, systems, and methods of use for a generator is disclosed. In one embodiment, the generator has a stator and a rotor and a first plurality of magnets coupled to the rotor and a second plurality of magnets coupled to the stator. An external magnetic housing may be coupled to an input shaft of the generator or surround the generator itself. A first layer of magnets produce a rotating magnetic field and a second layer of magnets create a static magnetic field, whether such magnets are in the generator itself or within an external magnetic housing. The disclosed generator increases the mechanical power inputted into the generator, which then produces an increased output of the generator.
