Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual inspection of thermal imaging videos is used to detect hot spots, then detailed thermal analysis can be performed, but the process becomes extremely time-consuming and subjective
Solution Approach 1:
The patent replaces the manual mechanical inspection process with an automated computerized image processing system. The system uses algorithms to automatically detect, segment, and analyze thermal hot spots in video frames, substituting human operators with computational methods that provide both speed and consistency in thermal analysis.
Solution Approach 2:
The thermal analysis system performs self-service by automatically processing thermal video data without requiring manual intervention. The computerized processing autonomously identifies hot spots, extracts temperature information, and generates analysis results, making the system self-sufficient and eliminating the time-consuming manual inspection step.
2Loss of information
If manual inspection by specialized operators is used, then thermal information can be extracted, but operator bias affects objectivity and repeatability
Solution Approach 1:
The patent replaces the subjective human judgment process with objective computerized image processing algorithms. The system consistently applies the same detection and analysis criteria to all thermal videos, eliminating operator bias and ensuring repeatable results across different analyses and operators.
3Quantity of substance
If standard analysis tools with thermal imaging cameras are used, then basic temperature data can be acquired, but the tools are lacking for analyzing complex physical phenomena
Solution Approach 1:
The patent segments the thermal video analysis into distinct processing stages: frame extraction, hot spot detection, segmentation, temperature measurement, and correlation with physical phenomena. This segmented approach allows the system to handle complex analysis tasks by breaking them down into manageable computational steps, enhancing versatility while maintaining basic data acquisition capabilities.
