Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional automation systems are used to work on moving objects, then placement errors between machine coordinate systems must be corrected manually, but this requires skilled techniques and complex processes that limit adaptability and versatility
Solution Approach 1:
The patent replaces manual mechanical coordinate system alignment with an optical sensing system. The sensor detects the actual position of the workpiece on the conveyor, and the processor automatically calculates the conveyor coordinate system relative to the robot's base coordinate system, eliminating the need for skilled manual placement error correction and enabling automatic adaptation to different work sites.
2Measurement precision
If manual correction of placement errors is performed, then coordinate accuracy can be achieved, but skilled interventions and complex setup procedures are required
Solution Approach 1:
The system performs self-alignment by automatically detecting the workpiece position and calculating the conveyor coordinate system. The sensor and processor work together to autonomously determine the relationship between coordinate systems without requiring skilled operators to perform manual alignment procedures, thereby achieving high measurement precision while simplifying operation.
Solution Approach 2:
The sensor continuously detects the actual position of the workpiece on the conveyor, providing feedback to the processor. The processor uses this feedback to calculate and determine the conveyor coordinate system, creating a closed-loop system that automatically achieves accurate coordinate alignment without manual intervention.
3Adaptability or versatility
If the system works with objects having varying motion rules and shapes, then versatility is improved, but the complexity of detecting and measuring positions increases
Solution Approach 1:
The sensor system is designed to detect the positions of works with varying motion rules and shapes using a unified detection approach. The processor applies the same coordinate system calculation methodology regardless of the specific workpiece characteristics, enabling the system to handle diverse objects without requiring different detection techniques, thus improving versatility while maintaining measurement capability.
