Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ostomy appliance adhesive failures lead to embarrassing and stigmatizing leakage incidents due to improper attachment, uneven skin surfaces, and moisture-related adhesive deterioration, with existing solutions failing to provide reliable and timely warnings for users and healthcare professionals.
Innovation Solution
A sensor patch designed for attachment to the base plate of an ostomy appliance, featuring a sensor assembly with electrodes and adhesive layers that can detect moisture propagation and adherence issues, allowing for electronic measurements to predict and prevent leakage by reducing the risk of incorrect application and enhancing user guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sensor patch is applied to monitor adhesive failure, then reliability of leakage detection is improved, but device complexity increases
Solution Approach 1:
The sensor patch is integrated within the base plate structure, with the sensor assembly nested between the adhesive layer and the base plate body. This nesting approach allows the monitoring function to be embedded within the existing device without adding external components, thus improving reliability while minimizing complexity increase.
Solution Approach 2:
The sensor patch combines multiple functions into a single integrated component: moisture sensing, adhesion monitoring, and structural support. By merging the sensor assembly with the base plate and adhesive layers, the system achieves reliable leakage detection without requiring separate monitoring devices, thereby managing device complexity.
2Manufacturing precision
If sensor patch application is made more detectable, then manufacturing precision can be improved, but device complexity increases
Solution Approach 1:
The sensor patch incorporates visual indicators that change color or appearance based on application status and sensor functionality. This allows users to verify correct application and sensor operation through simple visual inspection, improving manufacturing precision verification without requiring complex electronic detection systems.
Solution Approach 2:
The sensor patch includes self-diagnostic features that automatically indicate whether the patch has been applied correctly and whether the sensors are functioning. The patch itself provides feedback about its own application status, eliminating the need for external verification equipment and reducing overall system complexity.
