Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional nasal lavage systems are used, then the delivery mechanism is simple, but the liquid medication delivery is not optimal and rinsing efficacy is insufficient
Solution Approach 1:
The interface is segmented into multiple functional components: a body with multiple holes arranged in different patterns, a fence structure with vertical walls, and a base. This segmentation allows each component to contribute specifically to generating turbulent vortex flow, improving rinsing efficacy through complex fluid dynamics while keeping individual components manufacturable
Solution Approach 2:
The invention transitions from conventional simple linear flow to three-dimensional turbulent vortex flow by introducing angularly oriented holes and vertical fence walls. This dimensional change creates multi-directional fluid movement with both axial and angular momentum, significantly enhancing rinsing effectiveness throughout the nasal cavity
2Reliability
If turbulent vortex flow is generated using canted holes and fence, then the rinsing becomes more thorough and gentle, but the device structure becomes more complex
Solution Approach 1:
Different regions of the interface are designed with locally optimized characteristics: holes at different angles in specific patterns, fence walls at particular locations, and varying hole diameters. This local quality optimization ensures turbulent vortex flow is generated precisely where needed to maximize treatment effectiveness while minimizing overall structural complexity
Solution Approach 2:
The interface structure uses passive geometric features (canted holes, fence walls) that automatically generate turbulent vortex flow from the pressure of incoming liquid itself, without requiring external power sources or active control mechanisms. The structure serves itself to create the desired flow regime
