Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensor assembly is rigidly fixed to the rotation shaft, then the structure is simple, but the gap between the magnet and motor position sensor cannot be maintained constant when angle changes occur
Solution Approach 1:
The sensor assembly is designed to rotate relative to the rotation shaft within a predetermined angle range instead of being rigidly fixed. This dynamic adjustment capability allows the sensor assembly to automatically compensate for angle changes between the magnet and motor position sensor, maintaining a constant gap and ensuring reliable detection performance.
Solution Approach 2:
The system changes the angular parameter of the sensor assembly relative to the rotation shaft. By allowing the sensor assembly to rotate within a predetermined angle, the system adjusts this parameter to compensate for misalignment, thereby maintaining the optimal gap distance for sensor operation.
2Measurement precision
If the sensor assembly rotates within a certain angle to maintain constant gap, then detection performance is improved, but the structure becomes more complex
Solution Approach 1:
The sensor assembly incorporates a rotating mechanism that enables it to adjust its angular position within a predetermined range. This dynamic capability allows the system to maintain precise measurement of motor position by compensating for angle variations, improving measurement precision while adding only minimal structural complexity.
Solution Approach 2:
The sensor assembly automatically adjusts its own angular position to maintain the optimal gap with the magnet. This self-adjusting mechanism improves measurement precision without requiring external intervention or complex control systems, as the assembly serves itself to maintain proper alignment.
3Adaptability or versatility
If the angle between sensor assembly and rotation shaft changes, then adaptability is improved, but stability of the sensor position deteriorates
Solution Approach 1:
The sensor assembly is designed with a controlled rotating mechanism that allows angular adjustment within a predetermined range. This dynamic design provides adaptability to different operating conditions while maintaining positional stability through defined rotation limits and proper mechanical constraints.
Solution Approach 2:
The system allows controlled changes in the angular parameter of the sensor assembly to adapt to different operational requirements. By limiting the parameter change to a predetermined angle range, the system achieves adaptability while maintaining sufficient positional stability for reliable operation.
