Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the glue coating trajectory is fixed without adjustment, then the coating process is simple and fast, but the glue coating uniformity deteriorates due to placement position deviations
Solution Approach 1:
The system captures images of the water-cooling plate placement position, processes these images to determine actual position coordinates, compares them with preset standard coordinates to calculate deviation values, and uses this feedback to dynamically adjust the glue coating trajectory. This closed-loop feedback mechanism ensures accurate glue coating even when placement positions vary, resolving the contradiction between coating uniformity and system complexity.
Solution Approach 2:
The glue coating trajectory is transformed from a fixed static path to a dynamic adjustable path. The system calculates deviation between actual and standard placement positions, then dynamically regulates the coating trajectory coordinates based on this deviation. This dynamic adjustment capability allows the system to adapt to different placement positions while maintaining coating uniformity, without requiring overly complex hardware modifications.
2Manufacturing precision
If image analysis and trajectory regulation are implemented, then glue coating accuracy is improved, but processing time increases
Solution Approach 1:
The system performs image capture and placement position detection before the glue coating process begins. By determining the actual placement position and calculating trajectory deviations in advance, the system prepares the regulated coating trajectory beforehand. This preliminary action ensures that when coating actually occurs, the adjusted trajectory is already ready, minimizing additional processing time while maintaining high coating accuracy.
3Reliability
If automated image-based trajectory regulation is used, then coating quality is improved, but system complexity increases
Solution Approach 1:
The system replaces complex mechanical adjustment mechanisms with an automated vision-based control system. Instead of using complex mechanical devices to physically adjust the coating head position, the system uses image processing to detect placement deviations and automatically calculates trajectory corrections. This substitution of mechanical adjustment with automated digital control improves coating quality consistency while keeping the overall system complexity manageable through software-based solutions.
