Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple sensors are used to monitor different analytes, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improveblood glucose monitoring precisionVSAvoidsensor array complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sensor array is divided into multiple independent sensing elements, each designed to detect specific analytes (glucose, oxygen, pH, etc.). Each sensor element operates independently but contributes to the overall monitoring system, allowing precise measurement of multiple parameters simultaneously while maintaining manageable complexity through modular design

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wearable device integrates multiple sensing functions into a single platform that can monitor various analytes including glucose, oxygen, and pH levels. The system uses a unified processing architecture that handles data from different sensor types, enabling multi-analyte monitoring without proportionally increasing device complexity

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If continuous monitoring is implemented, then reliability is improved, but use of energy increases

Engineering Contradiction:
Improvecontinuous monitoring reliabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system employs periodic sampling of analyte levels rather than truly continuous monitoring, taking measurements at regular intervals. This approach maintains reliable monitoring capability while significantly reducing energy consumption compared to constant real-time monitoring, as the sensors and processing units can enter low-power states between measurements

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The device maintains continuous monitoring capability through persistent sensor contact with interstitial fluid, allowing immediate detection and measurement when analytes are present. The system continuously processes available data and updates readings without requiring active power consumption at every moment, maintaining reliability while managing energy use

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If sensor array monitors multiple analytes, then adaptability is improved, but manufacturing precision requirements increase

Engineering Contradiction:
Improvemulti-analyte monitoring capabilityVSAvoidsensor integration precision
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

Each analyte detection function is implemented as a separate, standardized sensor module with defined interfaces and mounting requirements. This segmentation allows each sensor type to be manufactured and tested independently with standardized precision requirements, then integrated into the wearable device through consistent mounting procedures, reducing overall manufacturing complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system accommodates different analyte monitoring requirements by adjusting sensor parameters such as sensitivity thresholds, sampling rates, and detection ranges rather than requiring fundamentally different sensor designs. This parameter-based adaptability allows the same physical platform to monitor multiple analytes with varying characteristics without proportionally increasing manufacturing precision demands

Inventive Principle:
Principle #35Parameter changes
