Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electrode assembly with sensors is integrated into the base plate, then sensing capability to detect adhesive performance and leaks is improved, but device complexity increases
Solution Approach 1:
The electrode assembly is integrated directly into the base plate structure, merging the sensing function with the adhesive component. This combination allows the base plate to simultaneously provide mechanical support and sensing capabilities, detecting adhesive performance and leaks through electrical measurements without requiring separate monitoring devices.
Solution Approach 2:
The base plate is designed to perform multiple functions: providing adhesive attachment, supporting the ostomy appliance, and monitoring adhesive performance through the electrode assembly. The electrodes can detect multiple parameters including adhesive integrity, moisture levels, and potential leaks, making the single component highly versatile.
2Ease of operation
If a top film layer is added to the base plate, then user comfort and handling are improved, but device complexity increases
Solution Approach 1:
A top film layer is incorporated into the base plate structure, providing a flexible and elastic surface that enhances user comfort and ease of handling. The thin film conforms to the skin and appliance contours while maintaining the structural integrity of the base plate, offering a soft interface between the rigid electronic components and the user's body.
3Reliability
If real-time monitoring is implemented, then detection of adhesive failure and leaks is improved, but loss of time for appliance replacement increases
Solution Approach 1:
The electrode assembly provides real-time feedback on adhesive performance by continuously monitoring electrical properties such as resistance and conductance. This feedback mechanism allows users to detect adhesive failure or leaks immediately, enabling timely appliance replacement before actual leakage occurs, thus preventing skin damage while optimizing replacement timing.
