Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional DC motors are used to achieve efficient power output, then power efficiency is improved, but device complexity and cost increase due to electronic control systems
Solution Approach 1:
The patent extracts and removes the complex electronic control system from the motor design, replacing it with a purely magnetic control mechanism. The electromagnetic assemblies and permanent magnets interact directly to produce rotation without requiring electronic controllers, resolvers, or encoders, thereby eliminating the associated complexity and cost while maintaining power efficiency.
Solution Approach 2:
The patent replaces the electronic control system with a magnetic field-based control mechanism. Electromagnetic assemblies generate magnetic fields that interact with permanent magnets to produce rotational motion, substituting electronic control with a magnetic field interaction system that achieves the same control function without electronic components.
2Power
If conventional motors are designed to meet high power needs, then power output is improved, but device complexity and cost increase
Solution Approach 1:
The patent divides the motor into multiple independent electromagnetic assemblies, each capable of producing rotational torque. These assemblies can be configured in series or parallel arrangements to achieve different power outputs. The segmentation allows the system to scale power output by adding or removing assemblies rather than increasing the complexity of a single assembly.
Solution Approach 2:
The patent employs a dynamic configuration where electromagnetic assemblies can be selectively activated or deactivated based on power requirements. The system can operate with different numbers of assemblies engaged, allowing flexible power output adjustment without requiring a complex control system to manage continuous variable power delivery.
3Force
If radial magnetic assemblies with alternating polarity are used, then torque efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The patent applies local quality by assigning specific polarities to specific regions of the electromagnetic assemblies and permanent magnets. Alternating N and S poles are positioned at specific locations around the circumference to create the desired magnetic field pattern for efficient torque production. This localized polarity assignment optimizes magnetic interaction at each position while maintaining overall manufacturing feasibility.
Solution Approach 2:
The patent utilizes parameter changes by varying the polarity arrangement and magnetic field strength across different regions of the assemblies. By changing the magnetic parameters (pole orientation, field intensity) in specific zones, the system achieves optimized torque efficiency without requiring complex manufacturing processes, as these parameter changes can be implemented through standard winding and magnetization techniques.

AI summary
A magnetic propulsion drive system provides power output by including the use of permanent magnets repelled by electromagnets on adjacent rotor assemblies. In some embodiments, the electromagnets may be inactive until synchronized to face an opposing permanent magnet of the same polarity. The electromagnet may be energized thus causing a repellant force with the permanent magnet causing radial momentum in the rotor assembly to rotate a larger drive module of rotor assemblies. Embodiments may include two or more drive modules arranged to position opposing magnets of the same type so that each drive modules is driven producing and output torque through a drive shaft.
