Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flushing time is extended to ensure thorough washing, then salt removal effectiveness is improved, but time consumption increases excessively
Solution Approach 1:
The system employs sensors to detect salt concentration in the cooling water pathway during flushing. The controller continuously monitors this feedback information and dynamically adjusts the flushing duration based on real-time salt concentration levels, stopping the flush when the concentration falls below a predetermined threshold, thus avoiding unnecessary extended flushing time
Solution Approach 2:
The system changes the flushing parameters (duration, water flow rate) based on detected salt concentration levels. When salt concentration is high, the system maintains or increases flushing intensity; when concentration drops below the threshold, the system reduces or stops flushing, dynamically optimizing the flushing process
2Productivity
If flushing time is shortened to improve efficiency, then time consumption is reduced, but salt removal effectiveness deteriorates
Solution Approach 1:
The sensor provides real-time feedback on salt concentration, allowing the controller to determine the precise moment when flushing has been sufficient. This feedback mechanism ensures that flushing stops as soon as the salt concentration threshold is met, preventing both under-flushing and over-flushing
Solution Approach 2:
The system enables the flushing process to self-regulate based on detected salt concentration levels. The controller automatically adjusts flushing duration and intensity according to real-time sensor data, making the system self-adjusting without requiring manual intervention or predetermined fixed timing
3Device complexity
If fixed flushing time is used regardless of water pressure, then system complexity is reduced, but flushing effectiveness deteriorates under varying pressure conditions
Solution Approach 1:
The system incorporates pressure sensors and salt concentration sensors that provide feedback to the controller. Based on this feedback, the controller automatically adjusts water flow rate and flushing duration to compensate for variations in water pressure, ensuring consistent flushing effectiveness across different pressure conditions
Solution Approach 2:
The flushing system transitions from a static fixed-time approach to a dynamic adaptive approach. The controller continuously adjusts flushing parameters (duration, flow rate) based on real-time sensor data regarding pressure and salt concentration, making the system flexible and responsive to changing conditions

AI summary
A system for flushing a cooling water pathway of a marine propulsion device with water supplied from a water source includes a water control device and a controller. The water control device is connected to the water source and the cooling water pathway of the marine propulsion device. The controller controls and causes the water control device to supply the water from the water source to the cooling water pathway so as to perform the flushing. The controller obtains propulsion device data including at least one of a pressure of the water, a flow rate of the water and a concentration of salt contained in the water in the cooling water pathway. The controller determines whether or not to stop a supply of the water by the water control device based on the propulsion device data.
