Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If serial blood draws are used for lactate measurement, then device complexity is reduced, but measurement precision and reliability deteriorate due to single-point measurements missing transient fluctuations

Engineering Contradiction:

Improvemeasurement system complexityVSAvoidlactate level detection accuracy

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent implements continuous lactate monitoring through an implantable sensor that continuously measures lactate levels in the patient's interstitial fluid, replacing discrete serial blood draws with an ongoing measurement process that captures transient fluctuations and provides real-time data for early deterioration detection

Inventive Principle:

Principle #20Continuity of useful action

Solution Approach 2:

The patent replaces the mechanical blood draw process with an implantable electrochemical sensor that directly measures lactate in interstitial fluid, eliminating the need for repeated needle insertions and laboratory processing while providing continuous real-time measurements

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of time

If periodic laboratory measurements are used, then loss of time for treatment response is reduced, but measurement precision deteriorates due to intervals between measurements missing rapid lactate changes

Engineering Contradiction:

Improvetime to detect lactate changesVSAvoidlactate level detection accuracy

Core Design Contradiction:

Loss of timeVSMeasurement precision

Solution Approach 1:

The continuous monitoring system maintains constant measurement of lactate levels, eliminating measurement intervals and ensuring that rapid lactate changes are captured immediately, enabling real-time detection of deterioration without the time loss associated with periodic sampling

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If continuous monitoring with implantable sensor is implemented, then measurement precision and reliability improve, but device complexity and ease of operation worsen due to implantation requirement

Engineering Contradiction:

Improvecontinuous monitoring reliabilityVSAvoidsystem deployment difficulty

Core Design Contradiction:
