Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment by technician is used, then machining accuracy can be maintained, but human resource consumption increases and automation is prevented
Solution Approach 1:
The machining apparatus performs self-diagnosis and self-correction by automatically detecting machining errors through detection devices, calculating correction parameters using a correction model, and adjusting its own operating parameters without requiring external technician intervention, thereby maintaining machining accuracy while achieving automation
Solution Approach 2:
The system establishes a closed-loop feedback mechanism where detection devices continuously monitor machining results, the processor analyzes detection data to determine errors, calculates correction parameters, and automatically adjusts operating parameters, creating a self-regulating system that maintains precision through automated feedback control
2Manufacturing precision
If manual adjustment by technician is used, then machining accuracy can be maintained, but human resource consumption increases
Solution Approach 1:
The machining apparatus performs self-diagnosis and self-correction by automatically detecting machining errors through detection devices, calculating correction parameters using a correction model, and adjusting its own operating parameters without requiring external technician intervention, thereby maintaining machining accuracy while achieving automation
Solution Approach 2:
The system replaces the mechanical/manual adjustment process with an automated information processing system that uses detection devices, processors, and correction models to automatically determine and correct machining errors, substituting human technician labor with automated computational and control systems
3Manufacturing precision
If frequent inspection is performed to maintain accuracy, then machining precision is improved, but productivity decreases due to time consumption
Solution Approach 1:
The detection device operates continuously or at predetermined intervals during machining to detect errors, and the processor continuously analyzes detection data and calculates correction parameters, ensuring uninterrupted monitoring and correction processes that maintain precision without stopping production flow
Solution Approach 2:
The system performs error detection and correction parameter calculation during the machining process itself rather than waiting for post-processing inspection, enabling real-time correction that prevents error accumulation and maintains precision throughout production without requiring separate inspection stages
