Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If suction nozzles are stored and managed in a complex system, then the management capability is enhanced, but the device complexity increases
Solution Approach 1:
The nozzle management system is segmented into independent functional modules: a storing device with multiple storage units for different nozzle types, a washing device with spray nozzles and drainage, a drying device with air blowers, and an inspection device with cameras. Each module operates independently but coordinates through a control device, reducing overall system complexity while maintaining comprehensive management capability.
Solution Approach 2:
The nozzle management machine integrates multiple functions into a single unified system. The same storage units accommodate various nozzle types, the washing device handles multiple nozzle configurations, and the inspection device uses standardized imaging procedures. This multi-functionality enhances adaptability without proportionally increasing complexity.
2Productivity
If multiple treatment processes are integrated into one machine, then productivity is improved, but the device complexity increases
Solution Approach 1:
The washing device, drying device, and inspection device are merged into a single integrated nozzle management machine. The control device coordinates all three treatment processes sequentially: washing with spray nozzles and drainage, drying with air blowers, and inspection with cameras and image processing. This integration improves productivity by eliminating the need for separate machines while managing complexity through unified control.
3Manufacturing precision
If suction nozzles are not properly managed and washed, then the mounting accuracy deteriorates, but the loss of time in management increases
Solution Approach 1:
The washing device performs preliminary cleaning of suction nozzles using spray nozzles that direct water onto the nozzle surfaces and internal passages, with drainage to remove contaminants. The drying device then performs preliminary drying using air blowers before the nozzles are installed for mounting operations. This preliminary treatment ensures mounting accuracy is maintained without requiring time-consuming manual cleaning and drying processes.
