Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the ostomy appliance is worn for extended periods to reduce changing frequency, then productivity is improved, but reliability deteriorates due to adhesive failure and skin damage
Solution Approach 1:
The monitor device continuously measures adhesive properties (cohesion, adhesion, viscoelasticity) and provides feedback to determine optimal appliance replacement timing. This feedback mechanism allows the system to extend wear time while maintaining reliability by replacing the appliance based on actual adhesive performance rather than fixed schedules.
2Reliability
If the appliance is changed frequently to maintain reliability, then reliability is improved, but loss of time increases due to repeated application and removal procedures
Solution Approach 1:
The system performs self-monitoring of adhesive properties through integrated sensors that automatically measure cohesion, adhesion, and viscoelasticity. This eliminates the need for manual assessment and enables precise determination of replacement timing, reducing unnecessary changes and associated time loss.
3Measurement precision
If monitoring sensors are added to track adhesive properties, then measurement precision is improved, but device complexity increases
Solution Approach 1:
Multiple sensing functions (cohesion measurement, adhesion measurement, viscoelasticity measurement) are merged into a single integrated monitor device that attaches to the ostomy appliance. This consolidation achieves comprehensive adhesive property monitoring while minimizing the increase in device complexity through unified design.
4Loss of substance
If the appliance is worn beyond optimal time to reduce material waste, then loss of substance is reduced, but object-generated harmful factors increase due to skin damage
Solution Approach 1:
The monitor device performs preliminary assessment of adhesive degradation before complete failure occurs. By detecting changes in cohesion, adhesion, and viscoelasticity in advance, the system enables timely appliance replacement that prevents skin damage while minimizing material waste through optimized wear time.
