Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid sampling devices often face inefficiencies due to clogging of coalescent elements, which reduces their effectiveness and requires frequent replacement, as passive methods like gravity-driven removal of coalescent material are not always effective.
Innovation Solution
A fluid flow sampling device with a coalescent filter and a movable sleeve that actively removes coalescent material by utilizing the pressure difference between the inlet and outlet to sweep across the filter, ensuring effective cleansing of coalescent material regardless of gravity orientation, and allows for easy removal and inspection or replacement of the filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive gravity-driven removal of coalescent material is used, then device complexity is reduced, but reliability deteriorates due to ineffective removal and frequent clogging
Solution Approach 1:
The system uses the fluid flow already present in the conduit to automatically clean the coalescent element. The fluid serves dual purposes: sampling and self-cleaning, eliminating the need for external power sources or complex active removal mechanisms while maintaining reliable operation
Solution Approach 2:
The invention utilizes hydraulic flow (fluid movement through the conduit) to generate the cleaning action. The flowing fluid creates pressure differential and shear forces that actively remove coalescent material from the element, providing reliable cleaning through fluid dynamics rather than mechanical or electrical systems
2Productivity
If coalescent element is continuously cleaned to maintain sampling efficiency, then productivity is improved, but device complexity increases due to additional cleaning mechanisms
Solution Approach 1:
The fluid flow system performs dual functions: it samples the fluid and simultaneously cleans the coalescent element. This self-service approach maintains high sampling productivity without requiring separate cleaning subsystems, keeping the device simple while ensuring continuous efficient operation
Solution Approach 2:
The fluid flow serves multiple purposes: it is both the sample being analyzed and the cleaning medium for the coalescent element. This multi-functionality maintains productivity by ensuring continuous effective sampling while avoiding the complexity of dedicated cleaning mechanisms
3Loss of time
If coalescent material accumulates on the filter, then device complexity is reduced, but loss of time increases due to frequent filter replacement
Solution Approach 1:
The system automatically cleans the coalescent element using the flowing fluid, preventing material accumulation without requiring manual intervention or complex scheduled maintenance systems. This reduces maintenance time while keeping the device simple through self-maintaining operation
Solution Approach 2:
The cleaning action occurs continuously as fluid flows through the conduit, preventing coalescent material accumulation in real-time rather than requiring periodic stoppages for maintenance. This continuous useful action minimizes downtime while maintaining a simple device structure

AI summary
A fluid flow sampling device comprises a housing and a sleeve disposed in the housing having openings corresponding to an inlet and an outlet of the housing. The sleeve is movable relative to the housing to an open position and a closed position. The open position aligns the openings of the sleeve with the inlet and the outlet to allow fluid to flow into the inlet, through the sleeve, and out of the outlet. The closed position blocks the inlet and/or the outlet with a portion of the sleeve such that fluid is prevented from flowing through the sleeve. A coalescent filter is disposed in the sleeve between the inlet and the outlet to allow some fluid to pass through the filter for sampling and to allow another portion of fluid to flow past the filter and out of the outlet to carry away coalescent material on the filter. Additionally, a sample outlet port facilitates removal of fluid from the sampling device for sampling.
