Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual or semi-manual analysis of diffraction images is used, then device complexity is reduced, but productivity and reliability of detection are worsened
Solution Approach 1:
The patent replaces manual mechanical analysis of diffraction images with an automated vision system that uses optical components (laser source, lenses, camera) and electronic processing (control unit, image analysis algorithms) to automatically detect and analyze target analytes, thereby increasing productivity while managing device complexity through systematic integration
Solution Approach 2:
The apparatus is designed to perform self-analysis through automated image capture, processing, and interpretation. The control unit automatically compares diffraction images against reference patterns and generates detection results without requiring manual intervention, enabling the system to serve itself in the analysis process
2Reliability
If automated detection apparatus is implemented, then productivity and reliability are improved, but device complexity increases
Solution Approach 1:
The vision system incorporates feedback mechanisms where the control unit continuously monitors and analyzes diffraction images, compares them with reference patterns, and adjusts processing parameters to optimize detection accuracy. This feedback loop ensures reliable detection results while systematically managing the complexity of the automated system
Solution Approach 2:
The detection apparatus is divided into distinct functional modules: laser source module, diffraction module, image capture module, and analysis module. Each module performs a specific function, which isolates complexity into manageable segments while maintaining overall system reliability through modular architecture
