Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ostomy appliances are used without monitoring systems, then the device structure remains simple and cost-effective, but leakage detection capability is absent leading to skin damage and discomfort
Solution Approach 1:
The patent replaces complex mechanical monitoring systems with electrochemical sensors that detect leakage through electrical conductivity changes in the adhesive layer. This substitution enables reliable leakage detection while maintaining relatively simple device structure by using electronic rather than mechanical sensing mechanisms.
Solution Approach 2:
The patent introduces an adhesive layer as an intermediary element that serves dual purposes: bonding the appliance to skin and acting as a sensing medium for leakage detection. This intermediary approach enables detection functionality without requiring separate complex sensing structures.
2Object-affected harmful factors
If no leakage monitoring is provided, then the appliance design remains straightforward, but users cannot detect leakage early resulting in skin irritation and discomfort
Solution Approach 1:
The patent implements a feedback system where sensors continuously monitor the adhesive layer's electrical properties and provide real-time information about leakage status to the user. This feedback loop enables early detection of leakage, allowing users to take preventive action before skin damage occurs, while the information loss is resolved through continuous monitoring and notification.
3Measurement precision
If simple adhesive layers are used without sensing capabilities, then manufacturing remains simple, but leakage detection is impossible
Solution Approach 1:
The patent merges the adhesive layer with sensing electrodes by integrating conductive elements directly into the adhesive structure. This combination enables precise moisture and leakage detection within the adhesive layer itself, while the manufacturing process remains relatively simple by combining multiple functions into a single integrated component rather than requiring separate assembly steps.
