Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If continuous blood glucose monitoring is used to determine insulin injection amount, then the accuracy of insulin dosage is improved, but the convenience and simplicity of operation deteriorates

Engineering Contradiction:

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The system performs preliminary actions by pre-collecting user characteristic information and establishing prediction models in advance. The insulin injection amount is predicted based on historical data and current blood glucose content, eliminating the need for continuous real-time monitoring during insulin administration, thus improving convenience while maintaining accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates a virtual copy of the continuous monitoring function through prediction models. Instead of requiring actual continuous blood glucose monitoring, the system uses a prediction model that copies the essential function of determining insulin dosage based on historical patterns and current measurements, reducing operational complexity.

Inventive Principle:

Principle #26Copying

2Reliability

If continuous blood glucose monitoring equipment is required, then the reliability of insulin dosage determination is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential function of continuous monitoring from the physical monitoring equipment. By separating the core function (determining insulin dosage) from the means of achieving it (continuous monitoring devices), the system maintains reliability through prediction models while eliminating the need for complex continuous monitoring hardware.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses the user's own historical blood glucose data and characteristic information to generate predictions, making the system self-sufficient. The prediction model learns from and adapts to individual user patterns, providing reliable insulin dosage determination without requiring external continuous monitoring infrastructure.

Inventive Principle:

Principle #25Self-service

3Reliability

If timely blood glucose feedback is required for insulin pump control, then the effectiveness of glucose metabolism control is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improveeffectiveness of glucose metabolism controlVSAvoidconvenience of insulin pump operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary prediction of insulin injection amounts based on historical data and current blood glucose content. This preliminary action provides the necessary feedback for insulin pump control without requiring continuous real-time interaction, maintaining effectiveness while improving ease of operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The prediction model acts as an intermediary between blood glucose measurements and insulin pump control. It translates current blood glucose content and historical patterns into recommended insulin injection amounts, providing effective glucose metabolism control while simplifying the interaction between patient and insulin pump.

Inventive Principle:

Principle #24Intermediary (Mediator)
