Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If heavy rotors are used to generate large amounts of torque, then torque generation is improved, but the rotor weight increases and form factor deteriorates
Solution Approach 1:
The rotor is segmented into multiple lightweight arms that can be independently positioned and activated. Each arm contains a magnet that interacts with electromagnetic coils, allowing torque to be generated through distributed electromagnetic forces rather than relying on a single heavy mass. This segmentation enables torque generation with significantly reduced rotor weight.
Solution Approach 2:
The patent replaces traditional mechanical torque generation (which relies on heavy rotating masses) with an electromagnetic system. Electromagnetic coils generate magnetic fields that interact with magnets on the rotor arms, producing electromagnetic force to generate torque. This substitution eliminates the need for heavy rotors while maintaining or improving torque output.
2Power
If traditional electromagnetic motors are designed for large-scale applications, then power output is improved, but adaptability to small projects deteriorates
Solution Approach 1:
The motor design incorporates adjustable parameters including variable electrical input patterns, configurable coil activation sequences, and scalable arm configurations. These features allow the same motor structure to be optimized for different power requirements and application scales, from small precision devices to larger mechanical drives, making it universally adaptable across diverse projects.
Solution Approach 2:
The motor employs dynamic control of electrical input patterns and coil activation sequences that can be adjusted in real-time. This dynamic capability allows the motor to adapt its performance characteristics to match different load requirements and application needs, enabling the same device to serve both small-scale and large-scale applications effectively.
3Power
If conventional motor designs are used, then electromagnetic conversion is achieved, but energy conversion efficiency deteriorates
Solution Approach 1:
The motor employs continuous electromagnetic interaction between the coils and rotor arm magnets, maintaining active force generation throughout the rotation cycle. By strategically positioning and activating coils to ensure continuous electromagnetic engagement, the system minimizes energy losses during transitions and maintains high conversion efficiency across the entire operational cycle, eliminating idle or low-efficiency periods.
Solution Approach 2:
The system dynamically adjusts electrical input parameters including voltage, current, and pulse timing to optimize energy conversion at different operational phases. By changing these parameters in response to rotor position and load conditions, the motor maximizes electromagnetic force generation while minimizing energy input requirements, thereby improving overall conversion efficiency.
