Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If field data is used for cold pool detection, then point-specific temperature measurements are obtained, but spatial analysis capability is lost
Solution Approach 1:
The patent divides the ocean area into multiple grid cells (e.g., 1°×1° or 0.5°×0.5° grids) and performs clustering analysis on temperature data within each grid. This segmentation allows spatial distribution to be preserved while enabling detailed local temperature analysis through standard deviation calculations within each grid cell.
2Area of stationary object
If Earth observation satellites are used for cold pool detection, then spatial coverage is improved, but detection capability is limited to solar radiant energy only
Solution Approach 1:
The patent integrates multiple data sources including satellite sea surface temperature data, buoy observations, and reanalysis data into a unified detection framework. This multi-source integration enables the system to detect cold pools using various parameters (temperature, standard deviation, temperature gradients) beyond just solar radiant energy, enhancing detection versatility while maintaining broad spatial coverage.
3Ease of operation
If traditional cold pool detection methods are used, then simple temperature thresholds are applied, but comprehensive temperature variation analysis is not performed
Solution Approach 1:
The patent employs multiple temperature parameters including mean temperature, standard deviation, temperature gradients, and clustering-based temperature categories. By calculating standard deviation within grid cells and using K-means clustering to identify temperature patterns, the system achieves comprehensive temperature variation analysis while maintaining operational feasibility through automated computational procedures.
