Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a force sensor is used for high-speed continuous detection, then detection speed is improved, but detection precision for small forces deteriorates
Solution Approach 1:
A lever assembly is introduced as an intermediary between the object being tested and the force sensor. The lever assembly amplifies the small pushing force applied by the object before it reaches the force sensor, enabling the sensor to detect small forces accurately while maintaining high-speed continuous detection capability
Solution Approach 2:
The lever assembly changes the force parameter by amplifying the magnitude of the pushing force. By using lever mechanical advantage, a small force F1 is transformed into a larger amplified force F2 that the force sensor can reliably detect, thus changing the detection parameter from direct small force measurement to amplified force measurement
2Measurement precision
If manual testing is used, then detection precision for small forces is improved, but automation level deteriorates
Solution Approach 1:
The force detection device is designed to be self-contained and automated. The lever assembly automatically amplifies forces, and the force sensor automatically detects and records data without requiring manual intervention. The system can be integrated into production lines for automated testing, eliminating the need for manual operation while maintaining high detection precision
3Measurement precision
If force amplification is applied, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The force detection device is segmented into distinct functional modules: the lever assembly for force amplification, the force sensor for detection, and the mounting plate for support. This modular segmentation allows each component to perform its specific function efficiently while keeping the overall system relatively simple and easy to manufacture
