Recessed Fluid Sensor Design for Drag Reduction and Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid flow sensors often suffer from damage during maintenance and generate drag, and they lack redundancy and resolution in measuring fluid pressure characteristics.
Innovation Solution
A fluid sensor design featuring a recessed surface with multiple sensor ports and transducers that measure fluid pressure, reducing the need for a projecting component, providing redundancy, and enhancing signal quality by encouraging high-pressure areas and minimizing flow separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a projecting component is used to measure fluid pressure, then measurement capability is provided, but the sensor is susceptible to damage during maintenance and generates drag
Solution Approach 1:
The patent inverts the conventional approach by using a recessed component instead of a projecting component. The recessed sensor port is set below the outer surface of the sensor body, eliminating the protruding elements that cause drag and vulnerability to damage during maintenance, while still enabling fluid pressure measurement through the recessed opening.
2Reliability
If a single sensor is used, then device simplicity is maintained, but redundancy and measurement resolution are insufficient
Solution Approach 1:
The patent segments the measurement function by incorporating multiple recessed sensor ports (first recessed sensor port and second recessed sensor port) at different locations on the sensor body. This segmentation enables redundant measurements and improved resolution by capturing pressure data from multiple spatial positions, while maintaining a relatively simple overall device structure.
