Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated passage planning is implemented for mobile structures with electrical propulsion systems, then navigation safety and range estimation accuracy are improved, but device complexity increases
Solution Approach 1:
The passage planning system is divided into multiple independent modules: environmental condition sensor, operational state sensor, logic device for range calculation, and user interface. Each module performs a specific function, making the overall complex system manageable and maintainable while ensuring reliable navigation safety through coordinated operation of all segments.
Solution Approach 2:
The system performs preliminary calculation of the operational range map before the mobile structure departs on a passage. By determining the maximum operational range in advance based on battery capacity, environmental conditions, and operational parameters, the system ensures navigation safety is established before the journey begins, allowing operators to plan routes within safe boundaries.
2Measurement precision
If environmental conditions are compensated for in range projection, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system continuously monitors environmental conditions (wind speed, current, temperature) and operational state (battery charge level, propulsion power) using sensors, and feeds this information back to the logic device. The logic device dynamically adjusts the operational range map based on real-time feedback, improving range projection accuracy by compensating for environmental factors while maintaining a manageable level of complexity through automated calculations.
Solution Approach 2:
The system changes multiple parameters simultaneously to calculate accurate range projection: battery capacity, charge level, propulsion power requirements, wind speed, current strength, and temperature. By integrating and dynamically adjusting all these parameters, the system achieves high measurement precision for range projection without requiring overly complex individual components.
3Reliability
If multiple operational parameters are monitored in real-time, then reliability is improved, but use of energy increases
Solution Approach 1:
The system performs periodic updates of the operational range map and sensor readings at strategically determined intervals rather than continuous monitoring. This periodic action maintains reliable range estimation by refreshing data at sufficient intervals while significantly reducing overall energy consumption compared to continuous real-time monitoring of all operational parameters.

AI summary
Techniques are disclosed for systems and methods to provide passage planning for a mobile structure. A passage planning system includes a logic device configured to communicate with a user interface associated with the mobile structure and at least one operational state sensor mounted to or within the mobile structure. The logic device determines an operational range map based, at least in part, on an operational state of the mobile structure, potential navigational hazards, and/or environmental conditions associated with the mobile structure. Such operational range map and other control signals may be displayed to a user and/or used to generate a planned route and/or adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.
