Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If preset position and depth control is used for connector plugging/unplugging, then automation is achieved, but manufacturing precision and reliability deteriorate due to machining tolerances and assembly errors
Solution Approach 1:
The patent employs force sensors to detect plugging force in real-time and provides feedback to the control system. The control system adjusts the motion device based on this feedback to achieve precise connector placement. This closed-loop feedback mechanism compensates for machining tolerances and assembly errors, ensuring reliable docking while maintaining automation.
Solution Approach 2:
The patent replaces traditional mechanical positioning and limiting devices with a force-based detection and control system. Instead of relying on mechanical stops and preset positions, the system uses force sensors to detect docking status and control the plugging process dynamically, improving precision while maintaining automation.
2Ease of operation
If preset plugging force is used, then operation is simplified, but reliability deteriorates due to potential damage or poor signal contact
Solution Approach 1:
The force sensor provides real-time feedback on plugging force to the control system, which dynamically adjusts the applied force. This ensures the plugging force remains within the optimal range - not too strong to cause damage, not too weak to ensure poor contact - thereby improving connection reliability while keeping the operation simple and automated.
Solution Approach 2:
The patent transitions from static preset force to dynamic force control. The plugging force is continuously adjusted during the plugging process based on real-time detection, allowing the system to adapt to variations in connector characteristics and achieve reliable connection without manual intervention.
3Manufacturing precision
If multiple detection methods (force, vibration, sound) are used to monitor plugging process, then manufacturing precision improves, but device complexity increases
Solution Approach 1:
The patent combines multiple detection methods (force sensing, vibration detection, sound detection) into a unified detection system. These different sensing modalities work together to comprehensively monitor the plugging process, providing multiple indicators for judging successful docking and improving precision through multi-parameter analysis.
Solution Approach 2:
The detection system is designed with multi-functionality, where a single integrated system performs force measurement, vibration analysis, and sound detection. This universal detection platform reduces overall system complexity compared to separate independent systems while achieving high precision through multiple detection dimensions.
