Thruster Status Indicator for Watercraft Propulsion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing watercraft propulsion systems lack effective indicators to monitor and alert drivers about the limited operational capacity of thrusters, particularly due to battery power and temperature constraints, which can lead to unexpected system failures during critical maneuvers.
Innovation Solution
A thruster system status indicator, such as a light on a keypad, that flashes or illuminates based on readings from temperature sensors and battery voltage, providing warnings of low capacity levels to prevent thruster shutdowns and ensure safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If thrusters are operated to enhance maneuverability, then the ability to control the vessel is improved, but the battery capacity is depleted and temperature constraints are exceeded
Solution Approach 1:
The system performs preliminary monitoring of battery capacity and temperature levels before thruster operation becomes critical. The status indicator provides advance warning to the operator about remaining thruster capacity, allowing the operator to plan maneuvers accordingly and avoid sudden loss of thruster functionality during critical operations.
Solution Approach 2:
The system continuously monitors thruster system parameters (battery capacity, temperature) and provides real-time feedback through the status indicator. This feedback loop enables the operator to adjust operation patterns based on current system state, preventing operation beyond safe limits while maximizing usable thruster capacity for maneuvering tasks.
2Ease of operation
If thrusters are operated for extended periods, then maneuverability is enhanced, but unexpected system failures occur during critical maneuvers
Solution Approach 1:
The status indicator system provides preliminary warning before thruster capacity is exhausted or temperature limits are reached. By alerting the operator in advance, the system prevents unexpected failures during maneuvers, allowing the operator to complete critical operations before thruster shutdown occurs.
Solution Approach 2:
The system creates a buffer by providing advance warning of approaching capacity or temperature limits. This cushioning effect gives the operator time to adjust operations or complete critical maneuvers before the actual failure point, reducing the risk of unexpected system failure during essential operations.
3Loss of information
If status indicators are added to monitor thruster capacity, then operational awareness is improved, but device complexity increases
Solution Approach 1:
The status indicator uses color changes (e.g., green, yellow, red) to communicate thruster capacity and temperature status. This visual coding system conveys complex information about battery level and temperature conditions in an immediately recognizable format, improving operator awareness without requiring complex displays or interfaces.
Solution Approach 2:
The system uses simple replicated indicator elements (such as multiple LEDs or segmented displays) to represent different aspects of thruster status. This approach provides comprehensive information through simple, standardized visual elements that are easy to manufacture and understand, avoiding the need for complex digital displays or interfaces.
