Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no sensor assembly is integrated into the base plate, then the device complexity is low, but the leakage detection capability is insufficient
Solution Approach 1:
The sensor assembly is integrated directly into the base plate structure, merging the sensing function with the existing base plate component. This integration allows the base plate to simultaneously serve as both a structural element and a sensing device, enabling leakage detection without requiring a completely separate complex system.
Solution Approach 2:
The base plate is designed to perform multiple functions: it provides structural support for the ostomy appliance and simultaneously acts as a sensing platform with integrated electrodes and moisture sensors. This multi-functionality reduces the need for additional separate components, addressing the complexity issue while improving detection capability.
2Ease of operation
If adhesive layers are used to attach the base plate, then the ease of operation is improved, but the measurement precision of moisture propagation is reduced
Solution Approach 1:
The adhesive layer is segmented into multiple regions with different properties: a first adhesive layer for initial attachment and a second adhesive layer for enhanced sealing. This segmentation allows different portions of the adhesive to serve different functions - some areas prioritize bonding while others are optimized for moisture detection, thereby maintaining both ease of attachment and measurement precision.
Solution Approach 2:
Different regions of the adhesive layer have different characteristics tailored to specific functions. The first adhesive layer provides general attachment, while the second adhesive layer provides enhanced sealing and moisture barrier properties. This local differentiation ensures that moisture propagation can be detected accurately at critical interfaces while maintaining overall ease of operation.
3Reliability
If real-time monitoring of adhesive performance is implemented, then the reliability of leakage detection is improved, but the device complexity increases
Solution Approach 1:
The sensor assembly automatically monitors adhesive performance and moisture propagation without requiring external intervention. The electrodes and moisture sensors continuously detect changes in the adhesive layer and stoma area, providing real-time data that triggers alerts when leakage is detected. This self-monitoring capability improves reliability while keeping the system relatively simple.
Solution Approach 2:
The system continuously monitors adhesive performance and provides feedback through alerts when moisture propagation or leakage is detected. This feedback mechanism enables timely user action to prevent skin damage, improving the reliability of the detection system without requiring complex additional components.
4Strength
If multiple adhesive layers are used, then the strength of bonding is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The adhesive system is segmented into a first adhesive layer and a second adhesive layer, each with specific functions. The first layer provides initial bonding, while the second layer enhances sealing and moisture barrier properties. This segmentation allows each layer to be optimized for its specific function, reducing the overall manufacturing precision requirements compared to a single complex adhesive layer.
Solution Approach 2:
Different regions of the adhesive layers have different properties tailored to specific functions. The first adhesive layer is optimized for general bonding, while the second adhesive layer provides enhanced sealing. This local differentiation allows standard manufacturing processes to produce reliable bonding without requiring extremely tight tolerances across the entire adhesive structure.
