Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional electric motors use fixed pole configurations, then the motor structure is simple, but the operational flexibility and adaptability to different speed and torque requirements are limited
Solution Approach 1:
The patent applies the dynamics principle by making the pole configuration changeable during motor operation. The electronic control module dynamically reconfigures the magnetic conductive wires to alter the number of poles, allowing the motor to adapt to different speed and torque requirements without physical modifications. This transforms a traditionally static motor structure into a dynamic, reconfigurable system.
Solution Approach 2:
The patent implements universality by enabling a single motor to perform multiple functions across different operating conditions. By reconfiguring the pole arrangements, the same motor can operate efficiently at various speeds and torque levels, replacing what would traditionally require multiple specialized motors for different applications.
2Use of energy by moving object
If traditional electric motors operate outside their optimal efficiency band, then they can still function, but energy efficiency deteriorates significantly
Solution Approach 1:
The patent applies parameter changes by modifying the electrical configuration parameters (pole numbers and arrangements) of the motor. The electronic control module adjusts these parameters in real-time based on load conditions, allowing the motor to maintain optimal efficiency across a wide operating range by keeping the motor operating within its efficiency band regardless of speed or torque demands.
Solution Approach 2:
The system implements feedback by continuously monitoring motor operating conditions and using this information to adjust pole configurations. The electronic control module receives feedback about current operating parameters and reconfigures the magnetic conductive wires to maintain optimal efficiency, creating a closed-loop control system that adapts to changing conditions.
3Ease of operation
If electric motors require external devices for speed and torque control, then precise control is achievable, but device complexity and integration requirements increase
Solution Approach 1:
The patent merges the speed and torque control functionality directly into the motor structure itself. By integrating the pole reconfiguration capability within the motor's magnetic conductive wires and electronic control module, the system eliminates the need for separate external control devices, simplifying overall system integration while maintaining precise control.
Solution Approach 2:
The motor performs self-service by internally reconfiguring its own pole structure to achieve desired speed and torque outputs. The electronic control module, integrated within the motor, automatically adjusts the magnetic conductive wire configurations in response to operating conditions, allowing the motor to control itself without requiring external intervention or additional control systems.
