Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual observation is used to identify interferences, then the system complexity is low, but the measurement precision and reliability of interference detection deteriorate due to subjective factors
Solution Approach 1:
The patent replaces manual observation (mechanical/human system) with automated image acquisition and optical detection systems. The image acquisition device captures sample images, and the optical signal detector measures photoelectric data, substituting human subjective judgment with objective instrumental measurement to improve interference detection precision.
Solution Approach 2:
The patent introduces intermediate devices (image acquisition device and optical signal detector) between the sample and the detection system. These intermediaries capture and quantify interference characteristics through image data and photoelectric data, providing objective measurements that improve detection precision while maintaining manageable system complexity through modular design.
2Reliability
If multiple detection methods (image acquisition and optical detection) are combined, then the measurement precision and reliability improve, but the device complexity increases
Solution Approach 1:
The control device serves multiple functions: it processes image data from the image acquisition device, processes photoelectric data from the optical signal detector, integrates both data types, and determines interference information. This multi-functionality consolidates complexity into a single processing unit while improving detection reliability through comprehensive data analysis.
Solution Approach 2:
The patent merges image data and photoelectric data into a unified interference determination process. The control device combines information from both detection methods to identify interferent information, achieving improved reliability by cross-validating results from multiple detection approaches while managing complexity through integrated processing.
3Reliability
If comprehensive state information from multiple sources is analyzed, then the reliability of interference identification improves, but the loss of time for data processing increases
Solution Approach 1:
The system performs preliminary data acquisition by capturing sample images and obtaining photoelectric data simultaneously during the detection process. This preliminary action prepares both data sources in advance, allowing the control device to efficiently integrate and analyze them without significant additional processing time, thus maintaining high reliability while minimizing time loss.
