Watercraft Drift Line Calculation Using Wind and Tidal Forces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nautical navigation devices do not provide drift pattern information for watercraft, placing a burden on users to predict drift patterns, which can be inaccurate due to varying environmental conditions, making fishing more challenging.
Innovation Solution
A nautical drift managing device that determines a drift line for a watercraft to reach a destination position by receiving destination position information and obtaining external force information, such as tidal and wind forces, using input and sensor circuitry, and processing this information to determine the optimal drift line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the user manually predicts drift patterns, then the device complexity is reduced, but the measurement precision of drift pattern accuracy deteriorates
Solution Approach 1:
The system automatically calculates drift patterns using sensor data and processing circuitry without requiring user intervention. The watercraft's own sensors and computer implement the drift calculation, making the system self-serving and eliminating manual prediction while maintaining high accuracy.
2Stability of the object's composition
If the engine is kept running to maintain position, then the position stability is improved, but the energy consumption increases
Solution Approach 1:
The system pre-calculates drift patterns and determines optimal drift lines before the watercraft needs to move. By having drift information ready in advance, the system enables the watercraft to drift efficiently to new positions without unnecessary engine operation, reducing fuel consumption while maintaining position stability when needed.
3Device complexity
If the nautical navigation device provides only basic navigation information, then the device complexity is reduced, but the productivity for fishing applications deteriorates
Solution Approach 1:
The system integrates multiple functions into a single device: basic navigation guidance, drift pattern calculation, drift line determination, and fishing-specific assistance. This multi-functional approach improves fishing productivity without proportionally increasing device complexity, as the drift calculation leverages existing sensor and processing resources.
