Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wave potential theory is used to assess directional wave spectra, then the methodology is simple and widely accepted, but the accuracy deteriorates in the presence of shearing currents
Solution Approach 1:
The patent changes the fundamental parameters of the wave assessment methodology by transitioning from wave potential theory to a new approach that incorporates shearing current effects. This involves modifying the mathematical model to include current profile parameters (velocity, direction, depth variation) alongside wave parameters, thereby improving measurement precision in shearing current environments while maintaining manageable complexity through systematic parameter integration
2Reliability
If wave potential theory is used, then the assessment process is straightforward, but the reliability deteriorates when ambient shearing currents are present
Solution Approach 1:
The patent introduces an intermediary computational framework that mediates between the measured wave parameters and the shearing current conditions. This intermediary approach processes wave measurements (period, height, direction) and current profile data (velocity, direction, depth) through a unified algorithm that reconciles both influences, thereby improving reliability without significantly complicating the operational process
3Manufacturing precision
If ambient shearing currents are considered in the assessment, then the accuracy of design parameters improves, but the complexity of the system increases
Solution Approach 1:
The patent segments the assessment system into distinct functional modules: wave parameter measurement, current profile measurement, interaction modeling, and design parameter determination. This segmentation allows each component to be optimized independently and simplifies the overall system complexity while maintaining high precision in design parameter output through systematic integration of shearing current effects
