Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If rotary potentiometers, light barriers, or magnetic sensors are used to measure deflection angle, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent extracts the magnet from the device body and places it on the carrier object, allowing the magnet carrier to be easily attached and removed without affecting the sensor system. This separation enables simple measurement of magnetic field direction changes caused by carrier movement, avoiding the need for complex rotary potentiometers or multiple light barriers while maintaining measurement precision.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the carrier position and the sensor measurement. By using a single magnetic sensor to detect changes in magnetic field direction caused by the magnet on the carrier, the system achieves precise measurement without direct mechanical contact or complex multi-sensor arrangements, thus reducing device complexity.
2Reliability
If magnet carrier is firmly installed with the device, then reliability is improved, but adaptability deteriorates
Solution Approach 1:
The patent segments the system into a device body containing the sensor and control unit, and a separate magnet carrier containing the magnet. This segmentation allows the magnet carrier to be easily attached and removed while maintaining reliable magnetic field interaction with the sensor, thus ensuring both reliability and adaptability.
Solution Approach 2:
The patent creates a dynamic attachment system where the magnet carrier can be easily attached and removed without affecting the sensor system's functionality. The magnetic field interaction remains consistent during operation, but the physical attachment can be dynamically changed, enabling easy replacement of the magnet carrier for different applications.
3Measurement precision
If multiple light barriers or magnetic sensors are used to determine deflection angle, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent uses a single magnetic sensor to detect changes in magnetic field direction in a different dimension (angular orientation) rather than using multiple sensors to measure position in multiple dimensions simultaneously. By detecting the direction of the magnetic field vector changes, the system achieves precise position determination with only one sensor, reducing device complexity.
