Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional conductive materials are used for rotors and stators, then structural strength is improved, but electrical resistance and heat generation increase
Solution Approach 1:
The patent changes the electrical conductivity parameter of the rotor and stator materials from conductive to non-conductive. This eliminates CEMF and reduces electrical resistance while maintaining structural integrity through alternative material selection and design configurations.
Solution Approach 2:
The patent employs composite material structures where non-conductive materials with appropriate mechanical properties are used for rotors and stators. This combines the benefits of non-conductivity with sufficient structural strength through material composition and design optimization.
2Force
If magnets are positioned close together to increase gauss ratings, then magnetic field strength is improved, but gauss leakage increases due to air gaps
Solution Approach 1:
The patent extracts and eliminates the source of gauss leakage by using non-conductive materials that prevent the formation of leakage paths. The design removes the problematic air gaps and conductive pathways that cause magnetic flux leakage while maintaining strong magnetic fields.
Solution Approach 2:
The patent introduces non-conductive materials as intermediaries between magnets and structural components. These materials serve as mediators that maintain the close positioning of magnets for high gauss ratings while preventing gauss leakage through their non-conductive properties.
3Power
If rotor and stator sizes are increased to improve power output, then power generation capacity is improved, but magnetic attraction resistance increases
Solution Approach 1:
The patent changes the magnetic interaction parameters by using non-conductive materials that eliminate magnetic attraction between moving and stationary parts. This allows for increased rotor and stator sizes to improve power output without the penalty of increased magnetic attraction resistance.
4Strength
If coils are enclosed within stators for protection, then mechanical protection is improved, but heat dissipation deteriorates
Solution Approach 1:
The patent applies local quality differentiation where coils are exposed in specific locations optimized for heat dissipation while other areas provide mechanical protection. This localized approach allows simultaneous achievement of thermal management and mechanical protection.
Solution Approach 2:
The patent transitions from a fully enclosed three-dimensional stator structure to a configuration where coils are exposed on the outer surface. This dimensional change from internal enclosure to external exposure dramatically improves heat dissipation while maintaining adequate mechanical protection through alternative design features.

AI summary
A low resistance generator includes a series of stator plates and rotors. Stator plates include the coils wrapped around coil spools. The stator plates and coil spools are made from non-conductive and non-ferromagnetic material. The coils are exposed to the surrounding air and cooled convectively by airflow caused by a rotation of the rotors in the gaps. Rotors house magnets and are disposed within gaps between the stator plates. The rotors are also made of non-conductive and non-ferromagnetic materials. The magnets may be disposed on the rotors to form columns. Two columns of magnets are joined together to form one or more closed magnetic loops, each column being joined by a gauss bridge disposed at first and second end rotors.
