Engineering Contradiction Analysis
1Productivity
If a simple linear interpolation method is used to determine water temperature at random depths, then the calculation process is simple and fast, but the accuracy of temperature determination deteriorates
Solution Approach 1:
The ocean water column is divided into four distinct layers (mixed layer, upper thermocline, lower thermocline, and deep ocean layer) with different thermal characteristics. Each layer is modeled separately using linear regression equations specific to its vertical gradient patterns, allowing accurate temperature determination in each stratum while maintaining computational efficiency through localized modeling.
2Measurement precision
If complex simulation models are used to simulate vertical distribution of seawater temperature, then the accuracy of temperature determination improves, but the device complexity and computational requirements increase
Solution Approach 1:
The complex vertical temperature distribution is segmented into four layers, each with its own simplified linear regression model. This segmentation reduces the overall model complexity by breaking down the continuous complex system into discrete manageable segments, while maintaining high accuracy through layer-specific parameterization.
Solution Approach 2:
The model uses parameter changes to represent different ocean layers by varying the linear regression parameters (slope and intercept) for each layer. This allows the system to adapt to different thermal structures without increasing computational complexity, as each layer is characterized by specific parameter values that capture its unique temperature gradient.

Function Achieved in This Case
This approach effectively compresses vertical distribution data of observed seawater temperature, enabling precise determination of water temperatures at random depths and aiding in studies of mixed layer thickness, thermocline strength, and internal water temperature structures.
Implementation Method 1
The generating the water temperature data at equal water depth intervals generates the water temperature data at equal water depth intervals by linearly interpolating water temperature data observed for each standard water depth
Implementation Method 2
The calculating the vertical gradient calculates the vertical gradient of the water temperatures for the water depths of each layer of the four-layer model by using a method of calculating a slope and an intercept of a linear regression equation in a least squares method
