Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual teaching point generation is performed by operator, then high accuracy of 1 mm or less can be achieved, but high operator skill is required and a lot of work time is consumed
Solution Approach 1:
The system enables self-service teaching point generation by automatically calculating teaching points based on sensor-detected operation lines and programmed search patterns, eliminating the need for manual operator intervention while maintaining high accuracy
Solution Approach 2:
The patent replaces manual mechanical teaching operations with an automated computational system that uses sensor data and algorithms to generate teaching points, substituting human skill-based operations with automated processing
2Extent of automation
If search point is used to determine next teaching point, then teaching process can be automated, but unexpected movement of robot may occur and position must be calculated repeatedly
Solution Approach 1:
The system uses sensor feedback to detect the actual operation line and continuously adjusts teaching point calculations based on real-world measurements, ensuring reliable robot movement while maintaining automation
Solution Approach 2:
The patent performs preliminary calculation of teaching points based on detected operation lines before executing robot movements, preventing unexpected movements by pre-planning the search path and teaching points
3Manufacturing precision
If repeated calculation of search point position is performed, then accurate teaching point can be generated, but it takes time to generate teaching point
Solution Approach 1:
The system performs preliminary detection of the operation line using sensors before teaching point generation, and pre-calculates search patterns based on this detected line, enabling efficient subsequent teaching point generation without repeated calculations
Solution Approach 2:
The patent creates a digital copy of the operation line from sensor data and performs calculations on this copy rather than repeatedly measuring the physical workpiece, significantly reducing calculation time while maintaining accuracy
