Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual calculation and input of infusion parameters is used, then medical staff can control liquid intake, but accuracy deteriorates due to calculation errors
Solution Approach 1:
The patent replaces the manual mechanical calculation and input process with an automated electronic calculation system. The control device automatically calculates the second intake based on the total intake and first intake, eliminating manual calculation errors and improving accuracy.
Solution Approach 2:
The system performs self-service by automatically calculating and setting infusion parameters without requiring manual intervention. The control device autonomously computes the second liquid's intake based on predefined relationships, reducing dependency on medical staff's manual calculations.
2Productivity
If manual setting of infusion parameters is used, then medical staff can adjust liquid intake, but efficiency deteriorates due to tedious parameter setting
Solution Approach 1:
The patent extracts the complex calculation and parameter setting tasks from the manual process and transfers them to the automated control device. This removes the burden of tedious parameter setting from medical staff while maintaining the necessary control functionality.
Solution Approach 2:
The manual parameter setting process is replaced with an automated electronic system that automatically determines infusion parameters. This substitution dramatically improves efficiency by eliminating the time-consuming manual calculation and input process.
3Loss of time
If manual calculation of infusion parameters is used, then medical staff can determine liquid volumes, but timeliness deteriorates due to delayed execution
Solution Approach 1:
The system performs preliminary action by pre-programming the calculation logic and relationships between different liquid intakes. When the total intake is set, the system immediately and automatically calculates the second intake without requiring manual computation, thus reducing time loss.
Solution Approach 2:
The manual calculation process is replaced with instant electronic calculation, eliminating the time delay associated with manual computations. The automated system immediately determines the second liquid's intake parameters as soon as the total intake is specified.

AI summary
A control method for a liquid infusion system includes receiving a command delivered by an input device and obtaining infusion attribute information from the input device depending on the command. The infusion attribute information includes parameter information, which includes a total intake value for a predetermined time period and at least one first intake value corresponding to at least one first liquid. At least one second intake value is obtained, corresponding to at least one second liquid based on the total intake and the at least one first intake. At least one infusion pump is then controlled with the first liquid to infuse the first liquid into a target, such as a patient, based on the at least one first intake. At one other infusion pump with the second liquid is then controlled to infuse the second liquid to the target based on the at least one second intake.
