Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic leakage detection devices are used, then leakage detection capability is improved, but production costs, user interface complexity, regulatory complexity, and environmental impact increase
Solution Approach 1:
The patent extracts the leakage detection function from complex electronic systems and implements it through a simple tactile indicator layer integrated into the adhesive wafer. The indicator layer contains moisture-sensitive particles that change tactile properties when exposed to leakage, providing detection capability without electronic components.
Solution Approach 2:
The tactile indicator is designed as a disposable component integrated into the adhesive wafer, eliminating the need for expensive, reusable electronic detection devices. The indicator is used once and discarded with the ostomy appliance, reducing production costs and regulatory burden.

4Ease of manufacture
If existing non-electronic leakage indicators are used, then production costs are reduced, but discreetness and reliability of leakage indication are insufficient
Solution Approach 1:
The patent replaces visual mechanical indicators with a tactile sensing system. The indicator particles change their tactile properties (softness, texture, temperature) when exposed to moisture, allowing users to detect leakage through touch rather than sight, improving reliability while maintaining low cost.
Solution Approach 2:
The patent changes the physical parameters of the indicator material from electronic to tactile-based moisture sensitivity. The indicator particles change their tactile properties (softness, texture) in response to moisture, providing a low-cost detection mechanism that does not require electronic manufacturing processes.
