Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the discharge device and filling device are connected and separated frequently, then the fluid can be efficiently transferred between devices, but fluid adheres to the connecting device surface causing leakage and operational issues
Solution Approach 1:
The patent applies preliminary anti-action by controlling the separation speed to be equal to or less than the connection speed. This preventive measure addresses fluid adhesion before it causes leakage problems. By anticipating the adhesion issue during separation and counteracting it through speed control, the system prevents harmful effects rather than reacting after leakage occurs.
Solution Approach 2:
The patent changes the operational parameter of speed by establishing a specific relationship between connection speed and separation speed. The control device adjusts these parameters dynamically, ensuring separation speed does not exceed connection speed. This parameter control modifies the fluid's behavior during connection and separation operations, preventing excessive adhesion that would lead to leakage.
2Speed
If the operation speed during separation is increased to improve efficiency, then fluid transfer becomes faster, but fluid adhesion to the connecting device increases causing leakage
Solution Approach 1:
The control device implements preliminary anti-action by preemptively limiting the separation speed to be equal to or less than the connection speed. This prevents fluid adhesion from becoming excessive before it can cause harmful leakage effects. The system anticipates the relationship between speed and adhesion, and counteracts potential harm through proactive speed management.
Solution Approach 2:
The control device monitors and compares the connection speed and separation speed, using feedback control to ensure the separation speed does not exceed the connection speed. This closed-loop control mechanism continuously adjusts the separation operation based on the established speed relationship, preventing fluid adhesion from reaching harmful levels while maintaining efficient operation.

AI summary
The adhesion of a fluid to a connecting device for connecting a discharge device and a filling device to each other so as to fill the fluid into the discharge device is suppressed. A discharge system includes a discharge device capable of being filled with a fluid for discharge and discharging the fluid, a filling device for filling the fluid into the discharge device, a connecting device for connecting the discharge device and the filling device to each other in a separable manner, and a control device. The control device of the discharge system controls an operation speed during a separating operation of separating the discharge device from the filling device to be equal to or less than an operation speed during a connecting operation of connecting the discharge device to the filling device.
