Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional TEM is used for virus imaging, then high resolution can be achieved, but the process is manual, tedious, and slow
Solution Approach 1:
The system employs automated image analysis algorithms and AI-based virus classification that perform detection and identification without manual intervention. The electron microscope automatically captures images, processes them through software algorithms, and generates diagnostic results, enabling the system to serve itself in the analysis workflow.
Solution Approach 2:
Manual mechanical operations in conventional TEM (sample loading, image capture, analysis) are replaced by an integrated automated system. The patent substitutes human-operated mechanical processes with computer-controlled automation, including robotic sample handling and algorithmic image processing, thereby increasing throughput while maintaining diagnostic accuracy.
2Measurement precision
If conventional TEM is used for virus imaging, then detailed viral structure can be observed, but the system is complex and expensive
Solution Approach 1:
The patent divides the virus imaging and analysis function into modular components: electron microscopy module, automated sample handling module, image processing module, and database module. Each module performs a specific function independently, allowing the system to maintain high imaging capability while reducing overall complexity through functional separation and standardized interfaces.
Solution Approach 2:
The automated system is designed to handle multiple virus types and imaging requirements through a single integrated platform. The electron microscope is configured with adjustable parameters and automated protocols that can adapt to different viral structures, eliminating the need for multiple specialized instruments and reducing system complexity.
3Reliability
If manual virus analysis is performed, then expert judgment can be applied, but the process is time-consuming and labor-intensive
Solution Approach 1:
The system incorporates feedback loops where image processing algorithms continuously refine virus detection based on captured images, and results are validated against database patterns. The automated classification system provides feedback on detection confidence levels, allowing for iterative improvement and ensuring reliable diagnostic accuracy without requiring prolonged manual review.
Solution Approach 2:
The system performs preliminary image processing, enhancement, and preliminary virus identification automatically before final diagnostic confirmation. By pre-processing images with algorithms that enhance viral features and filter out artifacts, the system prepares data in advance, reducing the time required for final analysis while maintaining expert-level accuracy.
