Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quantitative calculation method for coastal erosion early warning lines is established, then prediction accuracy and disaster prevention capability are improved, but calculation complexity and data processing requirements increase
Solution Approach 1:
The patent divides the coastal erosion prediction into multiple independent modules: (1) coastal erosion rate calculation module using monitoring data, (2) early warning line determination module for conventional conditions, (3) extreme condition adjustment module for sea level rise and storm waves, and (4) spatial scope calculation module. This segmentation allows each module to process specific data types and produce targeted outputs, reducing overall system complexity while maintaining comprehensive prediction capability.
Solution Approach 2:
The patent performs preliminary calculations of coastal erosion rates and determines early warning lines under conventional conditions before considering extreme conditions. This sequential approach allows the system to establish a baseline prediction first, then layer on extreme condition adjustments, making the overall calculation process more manageable and computationally efficient while improving prediction reliability.
2Reliability
If early warning lines are determined under extreme conditions (accelerated sea level rise and extreme storm waves), then disaster prevention capability is improved, but calculation complexity increases
Solution Approach 1:
The patent adjusts the early warning line calculations by changing key parameters to reflect extreme conditions. Specifically, it incorporates accelerated sea level rise rates and extreme storm wave parameters (height, duration, frequency) as modification factors applied to the conventional early warning lines. This parameter-based approach allows the system to maintain the same calculation framework while adapting to different scenario conditions, improving disaster prevention capability without proportionally increasing complexity.
3Productivity
If spatial scope of coastal erosion is calculated, then disaster management effectiveness is improved, but data processing requirements increase
Solution Approach 1:
The patent merges multiple data processing operations into integrated calculation modules. The coastal erosion rate calculation incorporates both monitoring data and landform data processing in a single module, and the early warning line determination integrates conventional and extreme condition analyses. This merging reduces the number of separate data processing steps and consolidates computational requirements, improving disaster management effectiveness while controlling data processing volume.
