Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If manual calculation and input of infusion parameters is used, then the system can operate with simple equipment, but the accuracy of liquid intake calculation deteriorates due to human error

Engineering Contradiction:
Improvesystem complexityVSAvoidliquid intake calculation accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system enables self-service by automatically calculating the second liquid's intake based on the total intake and first liquid's intake that were manually input. The control device performs the calculation without requiring manual intervention, eliminating human error while keeping the input process simple.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical calculation process (manual arithmetic by medical staff) with an automated computational system. The control device uses electronic computation to determine the second liquid's intake, substituting human mental/mathematical operations with a reliable computational mechanism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Device complexity

If manual parameter setting is used, then the system structure remains simple, but the execution efficiency deteriorates due to tedious operations

Engineering Contradiction:
Improvesystem structureVSAvoidparameter setting efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system performs self-service by automatically calculating and determining the second liquid's intake parameters based on the total intake and first liquid's intake. This eliminates the need for medical staff to manually perform tedious calculations and setting operations, significantly improving efficiency while maintaining a relatively simple system structure.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent extracts the complex calculation and parameter determination tasks from the manual operation process. By separating the automatic calculation function (performed by the control device) from the simple input function (performed by medical staff), the system improves efficiency while keeping the user interface simple.

Inventive Principle:
Principle #2Taking out (Extraction)

3Device complexity

If manual calculation is used, then the equipment cost remains low, but the time consumption increases due to tedious setting operations

Engineering Contradiction:
Improveequipment costVSAvoidparameter setting time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The control device performs self-service by automatically calculating the second liquid's intake based on the total intake and first liquid's intake. This automation eliminates the time-consuming manual calculation and parameter setting process, reducing time loss while maintaining low equipment costs through the use of a straightforward control system.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary action by pre-calculating the second liquid's intake parameters automatically once the total intake and first liquid's intake are input. This preliminary automatic calculation eliminates the need for subsequent manual computation and adjustment, saving significant time in the infusion setup process.

Inventive Principle:
Principle #10Preliminary action
