Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a wind model is determined based only on vessel structure or layout, then the determining process is simple, but the wind model accuracy deteriorates when cargo varies
Solution Approach 1:
The wind model is made dynamic by continuously updating it based on real-time sensor measurements of cargo configuration. Instead of using a static model based only on vessel structure, the system adapts the wind model to reflect current cargo conditions, resolving the contradiction between simplicity and accuracy.
Solution Approach 2:
Sensor measurements of cargo provide feedback to the wind model determination system. This feedback loop allows the system to automatically adjust the wind model based on actual cargo conditions, maintaining accuracy without requiring manual intervention while preserving ease of operation.
2Measurement precision
If sensor measurements are used to determine wind model, then wind model accuracy improves, but device complexity increases
Solution Approach 1:
The sensor system is designed to serve multiple functions: detecting cargo presence, determining cargo configuration, and providing data for wind model calculation. This multi-functionality reduces the need for separate specialized devices, thereby limiting the increase in device complexity while maintaining high measurement precision.
Solution Approach 2:
The system uses the vessel's existing sensor infrastructure and cargo management systems to provide wind model data autonomously. By leveraging available onboard resources rather than requiring entirely new dedicated equipment, the solution achieves high accuracy without proportionally increasing device complexity.
3Device complexity
If traditional wind models are used without cargo data, then device complexity is low, but navigation safety deteriorates due to inaccurate wind force predictions
Solution Approach 1:
The system performs preliminary determination of the wind model using available sensor data before navigation decisions are made. By having the wind model ready in advance with accurate cargo information, the system improves navigation safety without requiring complex real-time calculations during critical decision-making moments.
