VSEngineering Contradiction Analysis

1Reliability

If adhesive material is used to attach base plate to skin, then skin protection is provided, but moisture propagation and leakage cannot be reliably detected

Engineering Contradiction:
Improveadhesive performance monitoringVSAvoidmoisture propagation detection
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent replaces mechanical/adhesive-based attachment with an electrode-based sensing system. Electrodes are integrated into the base plate to detect moisture propagation through electrical conductivity changes, substituting the passive adhesive mechanism with an active sensing mechanism that provides real-time leakage detection capability.

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

Solution Approach 2:

The patent introduces electrodes as intermediary sensing elements between the adhesive material and the monitoring system. These electrodes detect changes in electrical properties caused by moisture propagation in the adhesive, serving as mediators that convert physical adhesive degradation into detectable electrical signals for real-time monitoring.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If sensor assembly with electrodes is integrated into base plate, then moisture propagation can be detected, but device complexity increases

Engineering Contradiction:
Improvemoisture propagation detectionVSAvoidsensor assembly integration
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent merges the sensor assembly with the base plate structure, integrating electrodes directly into the base plate rather than using separate external sensors. This consolidation reduces the number of discrete components and simplifies the overall device architecture while maintaining precise moisture detection capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The base plate is designed to serve multiple functions: it provides skin attachment through adhesive material and simultaneously functions as a sensing platform through integrated electrodes. This multi-functionality eliminates the need for separate sensing devices, reducing overall system complexity while enabling precise moisture propagation detection.

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

AI summary

An ostomy base plate includes an adhesive layer, a top layer, and a sensor assembly. The adhesive layer is adapted to adhere the ostomy base plate to skin of a user. The top layer is on a distal side of the ostomy base plate and has a top layer opening. The sensor assembly is disposed between the adhesive layer and the top layer and includes electrodes with electrical connection parts. The electrical connection parts of the electrodes extend through the top layer opening for electrical connection with a removable data monitor. The sensor assembly is adapted to monitor a state of condition of the adhesive layer.
