Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electric motors use a fixed number of poles, then the motor structure is simple and reliable, but the motor cannot dynamically adjust speed and torque, limiting operational flexibility and energy efficiency
Solution Approach 1:
The patent applies the dynamics principle by making the pole configuration movable and adjustable rather than fixed. The electronic control module dynamically reconfigures the magnetic conductive wires to change the number of poles based on operational requirements, enabling the motor to adapt to different speed and torque demands while maintaining a relatively simple physical structure.
Solution Approach 2:
The patent implements parameter changes by varying the number of active poles in the motor stator. The electronic control module adjusts the configuration of magnetic conductive wires to change pole parameters (number and arrangement), which directly affects motor speed and torque characteristics, allowing optimization of energy efficiency across different operating conditions.
2Use of energy by moving object
If electric motors are designed for high efficiency at specific operating points, then energy efficiency is improved at those points, but the motor cannot efficiently adapt to varying torque and speed requirements
Solution Approach 1:
The system dynamically adjusts the pole configuration to match varying load conditions. The electronic control module monitors operational requirements and reconfigures the magnetic conductive wires in real-time, allowing the motor to maintain high energy efficiency across a wide range of speed and torque conditions rather than being optimized for a single operating point.
Solution Approach 2:
The patent changes the operational parameters of the motor by varying the number of active poles. This parameter change allows the motor to shift its efficiency characteristics to match different operating conditions, maintaining optimal energy efficiency whether the motor is operating at high speed/low torque or low speed/high torque conditions.
3Ease of operation
If electric motors lack dynamic pole adjustment capability, then the control system is simple, but the motor cannot achieve precise real-time adjustments of speed and torque
Solution Approach 1:
The patent replaces complex mechanical pole-changing mechanisms with an electronic control system. Instead of physically moving or reconfiguring magnetic components mechanically, the system uses an electronic control module to adjust the configuration of magnetic conductive wires through electrical connections, achieving precise pole adjustment without mechanical complexity.
Solution Approach 2:
The electronic control module achieves precise control by electronically varying the pole configuration parameters. The system can rapidly and accurately adjust the number and arrangement of active poles in response to control signals, enabling precise real-time speed and torque control without the delays and mechanical wear associated with physical adjustment mechanisms.
