Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a position sensor is used to detect false triggering, then false triggering detection capability is improved, but device complexity increases
Solution Approach 1:
The position sensor serves multiple functions: it detects both the false triggered position and the non-false triggered catch position of the clamping device. By making the sensor multi-functional, the patent avoids adding separate detection mechanisms for different positions, thereby improving reliability without proportionally increasing device complexity.
Solution Approach 2:
The system uses the existing position sensor to automatically detect and identify false triggering conditions without requiring external intervention or additional specialized sensors. The evaluation device processes the sensor data to determine false trigger status, enabling the system to self-diagnose and maintain operation.
2Measurement precision
If manual inspection is required to check trap readiness, then detection accuracy is improved, but productivity decreases
Solution Approach 1:
The position sensor continuously monitors the clamping device position and provides feedback to the evaluation device. This automatic feedback mechanism replaces manual inspection, maintaining high detection accuracy while enabling continuous operation. The system can immediately identify false triggers and restore readiness without human intervention.
Solution Approach 2:
The patent replaces the manual mechanical inspection process with an automated sensor-based detection system. The position sensor and evaluation device electronically monitor trap status, substituting human judgment with automated measurement, thereby improving both productivity and operational continuity.
3Measurement precision
If multiple switches are added to detect different positions, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Instead of using multiple specialized switches for different position detections, the patent employs a single position sensor that can detect multiple positions (false triggered position, non-false triggered catch position, and clamped initial position). This universal approach reduces the number of components while maintaining comprehensive position detection capability.
Solution Approach 2:
The patent merges the functions of multiple potential position detection switches into a single position sensor. By combining these detection functions, the system achieves the same measurement precision with fewer components, reducing device complexity while maintaining the ability to distinguish between different clamping device positions.
