Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If deterministic wave field modeling methods are used to analyze wave characteristics, then measurement precision and reliability are improved, but computational complexity and processing time increase significantly
Solution Approach 1:
The patent extracts only the essential wave characteristics (elevation values at multiple points) needed for safety assessment, rather than performing complete deterministic wave field modeling. This selective extraction of critical parameters reduces computational complexity while maintaining sufficient measurement precision for safety decisions.
Solution Approach 2:
The method performs partial wave analysis by evaluating wave characteristics at selected observation points rather than comprehensive field modeling. This partial action approach provides sufficient information for safety assessment without the excessive computational resources required by complete deterministic models.
2Reliability
If comprehensive wave parameter analysis is performed to ensure accurate safety assessment, then reliability is improved, but processing speed decreases
Solution Approach 1:
The patent establishes predetermined danger thresholds for wave characteristics before real-time operation. These pre-calculated thresholds enable rapid comparison with observed wave parameters, ensuring reliable safety assessment without requiring complex real-time computations, thus maintaining high processing speed.
Solution Approach 2:
The wave field is segmented into discrete observation points where elevation values are measured. This segmentation allows the system to process wave data from multiple locations independently and combine results for safety assessment, improving both reliability through comprehensive coverage and productivity through parallel processing capability.
3Device complexity
If simple wave observation methods are used, then device complexity is reduced, but measurement precision and safety assessment quality deteriorate
Solution Approach 1:
The patent combines elevation measurements from multiple observation points to characterize wave groups and determine their dangerousness. This merging of data from several simple observation points achieves accurate wave characteristic characterization without requiring complex individual measurement devices at each location.
Solution Approach 2:
The observation system uses universal elevation measurement principles at multiple points that can be implemented with relatively simple devices. The same basic measurement technique applied across multiple locations provides comprehensive wave characterization, making the system both simple to implement and precise in its assessment.
