Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ostomy appliances are used without monitoring capabilities, then the device complexity is low, but the reliability of adhesive attachment deteriorates due to inability to detect erosion and leakage
Solution Approach 1:
The patent replaces manual inspection methods with automated sensor-based detection systems. Electrical sensors monitor adhesive erosion and moisture levels, substituting the need for mechanical examination by the user or clinician. This electrical/measurement-based approach improves reliability while the integrated design keeps complexity manageable.
Solution Approach 2:
The patent implements feedback mechanisms where sensors continuously monitor the adhesive layer condition and transmit data to processors. This feedback loop enables real-time detection of erosion and leakage, allowing timely intervention before skin damage occurs, thereby improving reliability without requiring complex external monitoring systems.
2Object-affected harmful factors
If ostomy appliances are changed frequently to prevent skin damage, then skin protection is improved, but the loss of time and increased waste occur
Solution Approach 1:
The patent employs preliminary detection capabilities that identify adhesive erosion and leakage risks before they cause skin damage. By detecting early signs of failure through sensors, the system allows users to replace appliances proactively based on actual condition rather than following fixed schedules, preventing skin damage without unnecessary early replacements.
Solution Approach 2:
Through continuous monitoring and feedback on adhesive layer integrity, the system provides real-time information about appliance condition. This enables optimal replacement timing based on actual wear rather than conservative estimates, reducing both skin damage risk and unnecessary waste from premature disposal.
3Measurement precision
If monitoring systems are added to ostomy appliances, then detection precision of erosion and leakage is improved, but the device complexity increases
Solution Approach 1:
The patent segments the monitoring function into separate sensor modules that can be integrated into the adhesive layer structure. Electrical sensors are distributed at different locations to detect erosion and leakage independently, allowing precise measurement through multiple data points while keeping each individual sensor component relatively simple.
Solution Approach 2:
The patent designs sensors with multi-functionality where the same sensor system detects both adhesive erosion and moisture leakage. This universal approach improves measurement precision for multiple parameters simultaneously while avoiding the need for separate complex monitoring systems for each function.
4Productivity
If sensors are integrated into the adhesive layer, then the productivity of appliance monitoring is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The patent merges the sensor integration process with the adhesive layer manufacturing process. Sensors are incorporated during the adhesive layer formation stage rather than as a separate post-manufacturing step, improving monitoring efficiency while maintaining manufacturing simplicity through process integration.
Solution Approach 2:
The patent performs sensor preparation and positioning in advance during the adhesive manufacturing process. By pre-integrating sensors into the adhesive layer before application, the system achieves high monitoring productivity without adding complex assembly steps during clinical use or requiring specialized post-manufacturing integration procedures.
