Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual data switching is performed by the operator when recognition errors occur, then the image processing error can be corrected, but the production efficiency is reduced due to production interruption and increased labor time
Solution Approach 1:
The system performs self-correction by automatically switching member data when recognition errors are detected, eliminating the need for operator intervention. The control unit autonomously determines when to switch between first and second member data based on recognition results, allowing the system to service itself and maintain both accuracy and productivity.
Solution Approach 2:
The manual mechanical operation of operator data switching is replaced with an automated control system. The control unit uses image processing results to automatically select between different member data sets, substituting human labor with an automated decision-making system that maintains reliability while preserving production efficiency.
2Reliability
If the operator re-edits member data to correct image processing errors, then the recognition accuracy can be improved, but the labor time and complexity increase
Solution Approach 1:
The system automatically corrects recognition errors by switching member data without operator intervention. The control unit monitors recognition results and autonomously switches between first and second member data, eliminating the need for operators to manually re-edit data and reducing labor complexity to zero.
Solution Approach 2:
Multiple member data sets (first and second member data) are prepared in advance for different component types. When a recognition error occurs, the system can immediately switch to the pre-prepared alternative data without requiring operators to create or edit data during operation, thus reducing labor time and complexity.
3Reliability
If the component mounting machine stops during data editing, then the data accuracy can be ensured, but the production efficiency is reduced
Solution Approach 1:
The control unit autonomously manages data switching without requiring production stoppage. When recognition errors are detected, the system automatically switches between first and second member data and continues production, maintaining both data accuracy through automated selection and production efficiency by eliminating stoppages.
Solution Approach 2:
The system maintains continuous production operation while handling data accuracy issues. The automated data switching mechanism allows the component mounting machine to continue mounting components without interruption, ensuring both data accuracy through proper member data selection and production efficiency through uninterrupted operation.
