Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment of measurement conditions is performed, then measurement accuracy can be optimized, but operation complexity and time consumption increase
Solution Approach 1:
The system performs preliminary automatic adjustment of measurement conditions (illumination intensity, camera exposure, focus) before actual measurement begins. The adjustment section automatically sets optimal parameters based on the measurement target, eliminating the need for manual pre-adjustment while ensuring measurement accuracy is achieved.
Solution Approach 2:
The measurement condition adjustment is performed automatically by the apparatus itself without requiring external manual intervention. The adjustment section monitors and modifies measurement conditions in real-time based on feedback from the measurement target, enabling self-service optimization of measurement accuracy.
2Measurement precision
If multiple measurement conditions are adjusted manually, then measurement quality improves, but time consumption increases
Solution Approach 1:
The automatic adjustment section continuously monitors and adjusts measurement conditions throughout the measurement process rather than requiring discrete manual adjustments. This continuous automatic optimization maintains high measurement quality while eliminating time losses associated with manual intervention between measurement stages.
Solution Approach 2:
The system replaces manual mechanical adjustment operations with automated electronic control mechanisms. The adjustment section uses electronic sensors and actuators to modify measurement conditions automatically, substituting the mechanical manual adjustment process with an automated control system that achieves the same quality improvements without time consumption.
3Measurement precision
If specialized knowledge is required for adjustment, then measurement accuracy improves, but ease of operation deteriorates
Solution Approach 1:
The adjustment section autonomously determines and implements optimal measurement conditions without requiring user expertise. The system self-evaluates the measurement target and automatically configures appropriate parameters, eliminating the need for specialized knowledge while maintaining measurement accuracy.
Solution Approach 2:
The system replaces the need for human expert judgment with automated electronic decision-making algorithms. The adjustment section uses embedded software and sensors to evaluate measurement requirements and select optimal conditions, substituting specialized human knowledge with automated intelligent control that achieves the same accuracy without requiring operator expertise.
