Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If vibration measurement and learning are performed to reduce distal end vibration, then processing accuracy is improved, but device complexity and operation time increase
Solution Approach 1:
The display device is designed to serve multiple functions: it displays the robot trajectory, overlays vibration state information, allows region selection, and triggers learning operations. By integrating these functions into a single device, the patent avoids the need for separate measurement devices, display systems, and control interfaces, thereby improving processing accuracy while limiting the increase in device complexity.
Solution Approach 2:
The system performs self-diagnosis and self-optimization by automatically measuring vibration, displaying it to the operator, and executing learning operations to reduce vibration. The robot control system uses the measured vibration data to automatically generate improved operation programs without requiring external intervention for each optimization step, thus improving processing accuracy while keeping the operation process streamlined.
2Measurement precision
If vibration state is displayed along the entire trajectory, then vibration analysis is improved, but information processing time and display complexity increase
Solution Approach 1:
The trajectory is divided into multiple regions, and the operator can select specific regions of interest for detailed vibration analysis. Instead of processing and displaying all trajectory data simultaneously, the system segments the trajectory and allows focused analysis of selected portions, thereby improving vibration analysis precision while reducing the time and computational resources needed for information processing.
Solution Approach 2:
The display device provides different levels of vibration information detail for different regions of the trajectory. Selected regions receive enhanced display treatment with detailed vibration state information, while other regions receive standard or reduced information. This local differentiation improves vibration analysis where needed while minimizing overall information processing time and display complexity.
3Manufacturing precision
If learning operation is performed for vibration reduction, then processing accuracy is improved, but operation time increases
Solution Approach 1:
The system performs vibration measurement and analysis before final operation execution, and conducts learning operations in advance to optimize the operation program. By performing these preparatory actions beforehand, the system establishes improved processing accuracy for future operations while allowing the actual production operations to proceed efficiently without repeated learning interruptions, thus balancing processing accuracy improvement with operational productivity.
