Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an external controller is used for intelligent control of the driving wheel assembly, then the control function is achieved, but the cost increases and stability deteriorates
Solution Approach 1:
The patent integrates the control circuit board directly into the motor structure, merging the motor and controller into a single integrated unit. This eliminates the need for separate external controllers, thereby reducing system complexity and improving stability while maintaining intelligent control functionality.
Solution Approach 2:
The integrated motor structure serves multiple functions: it provides both the driving force and the intelligent control capability within a single component. The control circuit board is embedded within the motor housing, allowing the motor to function as both actuator and controller, thus achieving multi-functionality.
2Adaptability or versatility
If an external controller is used for transmission control, then the control capability is provided, but the device complexity increases
Solution Approach 1:
The control circuit board is integrated within the motor housing, combining the motor and controller into a single structural unit. This merging eliminates the need for separate external controllers and complex wiring, thereby reducing device complexity while maintaining full transmission control capability.
3Device complexity
If the motor has a single structure, then the structure is simple, but the intelligence and functionality are limited
Solution Approach 1:
The motor structure is designed to perform multiple functions: it provides mechanical driving force through the rotor and stator, while simultaneously housing the control circuit board for intelligent control. This multi-functional design maintains structural simplicity while enhancing intelligence and functionality.
Solution Approach 2:
The control circuit board is integrated within the motor housing, merging the actuator and controller functions into a single structural unit. This integration maintains the simplicity of having a single motor component while adding intelligent control capabilities through the embedded circuit board.
