Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single bridge structure is used for fluid delivery, then the device complexity is reduced, but the fluid management capability and pressure distribution effectiveness are insufficient
Solution Approach 1:
The bridge structure is divided into a first bridge and a second bridge, each with independent fluid pathways. The first bridge delivers instillation fluid while the second bridge removes wound exudate, allowing independent fluid management capabilities without requiring a single complex multi-functional bridge
2Reliability
If polymeric films with features projecting into fluid pathways are added to bridges, then the pressure distribution and fluid management are improved, but the manufacturing complexity increases
Solution Approach 1:
Polymeric films with specific features (protrusions, recesses, patterns) are applied selectively to specific bridges and fluid pathways. The first bridge receives a first polymeric film while the second bridge receives a second polymeric film, allowing optimized pressure distribution and fluid management at each location without requiring complex features throughout the entire device
3Measurement precision
If independent fluid coupling of multiple bridges is implemented, then the fluid management precision is improved, but the device complexity increases
Solution Approach 1:
Each bridge is equipped with independent fluid pathways that can be separately coupled to fluid sources and sinks. The first bridge connects to an instillation fluid source while the second bridge connects to a collection container, enabling precise independent control of fluid delivery and removal without requiring a complex integrated fluid management system
