Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual setting of flushing parameters is used, then flexibility in parameter adjustment is maintained, but setting efficiency is low

Engineering Contradiction:

Improveparameter setting efficiencyVSAvoidautomatic parameter determination

Core Design Contradiction:

ProductivityVSExtent of automation

Solution Approach 1:

The system automatically determines flushing parameters based on feeding parameters without requiring manual intervention. The control unit autonomously calculates and sets flushing volume, rate, and timing based on the nutrient solution characteristics and feeding regimen, eliminating the need for healthcare professionals to manually adjust these parameters.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system dynamically adjusts flushing parameters based on changes in feeding parameters. When feeding parameters such as nutrient solution type, concentration, or feeding rate are modified, the system automatically recalculates and updates the corresponding flushing parameters to maintain optimal flushing effectiveness while preventing tube blockage and excessive flushing.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If fixed flushing parameters are used, then operation simplicity is maintained, but adaptability to working state changes is lost

Engineering Contradiction:

Improveadjustment to working stateVSAvoidparameter setting complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The flushing parameters are made dynamic rather than fixed. The system continuously monitors the feeding process and automatically adjusts flushing parameters in response to changes in feeding rate, nutrient solution type, and duration. This dynamic adjustment ensures optimal flushing effectiveness adapts to varying working conditions without requiring manual reconfiguration.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms to monitor the feeding process and adjust flushing parameters accordingly. By monitoring feeding parameters and working state information, the control unit receives feedback and automatically modifies flushing parameters to maintain optimal performance, preventing both tube blockage and excessive flushing.

Inventive Principle:

Principle #23Feedback

3Reliability

If excessive flushing is performed to prevent blockage, then tube patency is improved, but diarrhea complication risk increases

Engineering Contradiction:

Improvetube blockage preventionVSAvoiddiarrhea risk from excessive flushing

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system precisely controls flushing parameters including volume, rate, and frequency based on the specific feeding parameters. By calculating optimal flushing parameters rather than using excessive fixed amounts, the system maintains sufficient flushing to prevent tube blockage while avoiding excessive flushing that could cause diarrhea. The flushing volume and rate are dynamically adjusted to match the feeding regimen.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system uses feedback from monitoring feeding parameters and working state information to adjust flushing parameters in real-time. This feedback mechanism ensures that flushing is performed only to the extent necessary to maintain tube patency, preventing both blockage and the harmful effects of excessive flushing such as diarrhea.

Inventive Principle:

Principle #23Feedback

AI summary

A method for controlling a nutrient infusion apparatus, includes: acquiring a feeding parameter; automatically determining a first flushing parameter according to the feeding parameter and a preset flushing rule; and controlling the nutrient infusion apparatus to flush according to the first flushing parameter. Healthcare personnel, when setting parameters, thus only need to set the feeding parameter, and the corresponding flushing parameter can be determined automatically. Furthermore, relative to having to set the flushing parameter manually, the accuracy of automatically determining the flushing parameter according to the feeding parameter is also higher, which improves the accuracy of parameter setting, which in turn improves the accuracy of the flushing control.
