Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the substrate is conveyed at a fixed speed, then the conveyance device is simple to control, but the processing time cannot be optimized for different conveyance distances
Solution Approach 1:
The conveyance speed is changed from a fixed value to a dynamic value that varies according to the conveyance distance. The control device calculates the optimal conveyance speed based on the measured conveyance distance and preset time parameters, allowing the system to adapt its operation to different substrate positions and processing requirements.
Solution Approach 2:
The conveyance speed parameter is adjusted based on the conveyance distance. By changing the speed parameter dynamically according to the distance the substrate needs to travel, the system optimizes processing time while maintaining simple control logic through preset time-based calculations.
2Productivity
If the conveyance speed is increased to reduce processing time, then productivity improves, but the substrate may not be properly positioned or processed at the work position
Solution Approach 1:
The control device uses feedback from the conveyance distance measurement to adjust the conveyance speed. By continuously monitoring how far the substrate has traveled and comparing it with the target work position, the system can modify the speed to ensure accurate positioning while optimizing overall processing time.
Solution Approach 2:
The system performs preliminary calculations of the required conveyance speed based on the measured distance and preset time parameters before the substrate reaches the work position. This allows the conveyance device to be pre-configured with the optimal speed profile, ensuring both timely arrival and accurate positioning.
