Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If invasive blood withdrawal procedures are used, then measurement accuracy is improved, but patient comfort and convenience deteriorate

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidpatient comfort

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent replaces the mechanical invasive blood withdrawal system with an electromagnetic sensing system. The device uses electromagnetic signals to interact with blood in the body part, eliminating the need for physical blood extraction while maintaining measurement capability through non-invasive sensing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces an electromagnetic signal as an intermediary between the measurement device and the blood glucose. Instead of directly extracting blood, the device sends electromagnetic signals that interact with the blood in the body part, and the response signal carries information about glucose concentration without requiring physical contact or invasion.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If non-invasive electromagnetic measurement is used, then patient comfort is improved, but measurement accuracy deteriorates due to signal variability

Engineering Contradiction:

Improvepatient comfortVSAvoidmeasurement accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent employs feedback mechanisms where the device measures the response signal from the electromagnetic interaction and uses this information to adjust and refine glucose concentration determination. The system continuously monitors and processes the response signal to compensate for variability and improve measurement accuracy over time.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent utilizes changes in electromagnetic signal parameters (frequency, amplitude, phase) that occur when interacting with blood containing different glucose concentrations. By detecting and analyzing these parameter changes in the response signal, the device can determine glucose levels accurately despite the non-invasive approach.

Inventive Principle:

Principle #35Parameter changes

3Reliability

If repeated blood withdrawal procedures are performed, then continuous monitoring capability is improved, but time consumption and inconvenience increase

Engineering Contradiction:

Improvecontinuous monitoring capabilityVSAvoidtime consumption

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent enables continuous monitoring by maintaining persistent electromagnetic interaction with the blood in the body part. Instead of discrete repeated procedures, the device can continuously send electromagnetic signals and receive response signals, providing ongoing glucose level information without interruption or repeated patient intervention.

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent allows the body's blood to serve the measurement function continuously without requiring external intervention. The electromagnetic signals interact with the blood in situ, and the blood itself provides the measurement information through its electromagnetic response properties, eliminating the need for repeated manual blood extraction and analysis.

Inventive Principle:

Principle #25Self-service
