Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no monitoring system is integrated into the ostomy appliance, then the device complexity is low, but the reliability of detecting moisture propagation and leakage risk is insufficient
Solution Approach 1:
The monitoring system is merged with the base plate by integrating electrodes directly into the adhesive layer structure. The electrodes are embedded within the adhesive material itself, combining the adhesive function with the sensing function in a single integrated component, thereby improving detection reliability without significantly increasing overall device complexity
Solution Approach 2:
The adhesive layer serves multiple functions: it provides structural bonding between the base plate and skin, and simultaneously acts as the sensing medium containing electrodes for detecting moisture propagation. This multi-functionality allows the same component to fulfill both mechanical and monitoring roles, resolving the contradiction between reliability and complexity
2Measurement precision
If electrodes are integrated into the adhesive layer, then moisture propagation detection capability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The adhesive layer is designed with spatially varying properties: different regions contain electrodes at specific locations optimized for detecting moisture propagation from the stoma outward. The electrode density and configuration are tailored to local detection needs, with higher precision requirements only where moisture detection is most critical, rather than uniform high precision throughout the entire adhesive layer
Solution Approach 2:
The patent utilizes changes in electrical resistance parameters of the adhesive material as moisture propagates through it. By monitoring resistance changes over time and across different electrode pairs, the system achieves precise moisture detection without requiring extremely precise electrode placement, as the measurement is based on parameter changes in the material itself rather than geometric precision
3Object-affected harmful factors
If real-time monitoring of adhesive layer integrity is implemented, then user safety is improved, but the loss of energy increases due to continuous monitoring
Solution Approach 1:
Instead of continuous monitoring, the system performs measurements at periodic intervals. The monitor device can be activated at scheduled times or triggered by user interaction to assess adhesive layer integrity. This periodic measurement approach provides sufficient safety monitoring while significantly reducing energy consumption compared to continuous real-time monitoring
Solution Approach 2:
The adhesive layer itself serves as the sensing medium, utilizing its inherent electrical properties (resistance changes) to indicate moisture propagation and potential failure. The material essentially monitors its own condition through passive electrical property changes, eliminating the need for active energy-consuming sensors embedded within the adhesive structure
