Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a production line type repairing solution is used, then automation and productivity are improved, but device complexity and installation difficulty increase
Solution Approach 1:
The system is divided into separate functional modules: a conveyor device for panel transport, a detection device for defect scanning, a repairing device for defect correction, and a control device for coordination. Each module operates semi-independently, allowing simplified installation and maintenance while maintaining automated productivity.
Solution Approach 2:
The detection device and repairing device are made movable along the conveyor path rather than being fixed at specific positions. This dynamic arrangement allows the same equipment to serve multiple panels at different locations, reducing the total number of devices needed and simplifying system complexity while maintaining high automated throughput.
2Extent of automation
If a production line type repairing solution is used, then automation is improved, but floor area requirements increase
Solution Approach 1:
By making the detection and repairing devices movable rather than fixed, the system compactly utilizes the space along the conveyor path. The devices can be repositioned to work on different panels without requiring additional floor space, thereby maintaining high automation levels in a compact footprint.
Solution Approach 2:
The system utilizes the vertical dimension and lateral movement along the conveyor rather than expanding horizontally across large floor areas. The movable devices operate above or beside the conveyor path, effectively using three-dimensional space to reduce two-dimensional floor space requirements.
3Measurement precision
If the panel is halted for scanning and repairing operations, then measurement precision and manufacturing precision are improved, but productivity decreases
Solution Approach 1:
The conveyor operates in a periodic cycle: panels are conveyed to the work position, halted briefly for detection and repair operations, then conveyed forward to the next position. This rhythmic stop-and-go operation ensures precise defect detection and repair while minimizing overall cycle time through efficient coordination of multiple panels in the production flow.
Solution Approach 2:
The halting duration at each position is minimized to only the essential time needed for detection and repair operations. The system quickly completes the precision work and immediately resumes conveyor motion, skipping unnecessary delays and maintaining high overall productivity despite the intermittent stops.
4Device complexity
If movable detection and repairing devices are used, then device complexity is reduced, but measurement precision and manufacturing precision may worsen
Solution Approach 1:
The control device receives real-time position information from sensors about the panel and movable device locations, and uses this feedback to dynamically adjust the timing and positioning of detection and repair operations. This closed-loop control ensures that even with movable components, the precision of defect detection and repair application is maintained at high levels.
