Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radar wave sensing is used to forecast ship motions, then forecasting accuracy is improved, but system complexity increases
Solution Approach 1:
The system segments the forecasting task into distinct modules: radar wave sensing for ocean wave detection, METOC models for atmospheric conditions, ship motion models for prediction, and scrolling display for visualization. Each module handles a specific aspect of the forecasting process, improving overall accuracy while managing complexity through functional decomposition.
Solution Approach 2:
The radar system serves multiple functions: it detects ocean waves, provides real-time ship position data, and feeds information to both METOC and ship motion models. This multi-functionality allows the same hardware to support comprehensive forecasting without proportionally increasing system complexity.
2Loss of information
If scrolling forecast displays are implemented, then information presentation quality is improved, but device complexity increases
Solution Approach 1:
The display system uses dynamic scrolling to continuously update forecast information as new radar data arrives. The scrolling mechanism automatically adjusts to present the most current predictions while maintaining historical context, ensuring information remains current without requiring manual intervention or complex configuration.
Solution Approach 2:
The system creates visual representations (graphical displays) of the forecasted ship motion data derived from radar sensing and modeling. These graphical copies present complex numerical forecasts in an intuitive visual format that is easier to interpret and monitor at a glance.

AI summary
Systems and methods for ship motion forecasting are described herein. These ship motion forecasting systems can enable accurate real-time forecasting of waves and resultant vessel motions, and the useful displaying of such forecasts to users. In general, the ship motion forecasting systems and methods provide users with useful indications of ship motion forecasts by generating scrolling graphical representations of the ship motion forecasts. For example, the systems can be implemented to display on a first window portion a plurality of graphical representations of ship motion forecasts generated over a plurality of forecast cycles, where the graphical representations of new ship motion forecasts are added as generated, and where the graphical representations of previously generated ship motion forecasts are scrolled as new ship motion forecasts are added.
