Filter Water Separation Conical Coalescing Flow Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current filtration systems face challenges in effectively separating water from fluids, particularly in fuel filtration, where water coalescing and removal are not adequately addressed, leading to inefficiencies and potential fluid contamination.
Innovation Solution
The development of a filter assembly with a tubular ring of filter media, end caps, and a water coalescing cone that forms a conical coalescing flow path, facilitating the separation of water from dirty fluids by creating a pressure drop and promoting water separation through a combination of filter media and cone-shaped flow paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter media is used to remove water from fluid flow, then water separation is achieved, but water coalescing efficiency is insufficient
Solution Approach 1:
The filter assembly is divided into distinct functional segments: a filter media portion for particle filtration and a water separator portion with a conical coalescing element for water separation. This segmentation allows each component to specialize in its specific function, improving overall water separation efficiency without requiring the entire filter structure to be redesigned
Solution Approach 2:
A conical coalescing element is introduced as an intermediary component between the filter media and the fluid flow path. This element serves as a mediator that promotes water droplet coalescence by providing a large surface area for water to accumulate and coalesce, thereby enhancing water separation efficiency without directly modifying the filter media itself
2Reliability
If water coalescing cone is added to promote water separation, then water removal efficiency improves, but device complexity increases
Solution Approach 1:
The water separator portion is merged with the filter element in a integrated assembly where the conical coalescing element is positioned within the filter housing. This merging combines the filtration and water separation functions into a single replaceable unit, improving water removal efficiency while avoiding the complexity of separate independent systems
Solution Approach 2:
A conical geometry is introduced in the vertical dimension within the existing filter housing space. The conical coalescing element utilizes the vertical space efficiently, creating additional separation surface area without significantly increasing the horizontal footprint or overall device complexity
3Reliability
If filter media is used to filter impurities, then fluid purification is achieved, but water coalescing and removal is not adequately addressed
Solution Approach 1:
The filtration system is segmented into two distinct functional portions: the filter media portion that removes particulate impurities and the water separator portion that addresses water contamination. This segmentation ensures that each type of contamination is addressed by the specialized component designed for that purpose, achieving comprehensive fluid purification
Solution Approach 2:
The conical coalescing element acts as an intermediary that specifically targets water droplets in the fluid stream, promoting their coalescence and separation before the fluid reaches downstream components. This intermediary mechanism addresses the harmful effect of water contamination without interfering with the particulate filtration function

AI summary
A filter, filter element and filter assembly are provided. The filter includes a water separating device for separating water from a dirty fluid flow. The water separator includes a fluid flow path that varies in cross-sectional area to vary pressure of the fluid therethrough. A top portion of the water separator is formed as a structurally independent piece from a bottom portion of the water separator. The top portion may be permanently or releasably secured to filter media of the filter via an end cap coupled to an end of the filter media. The bottom portion may be integrally or releasably secured to a housing of the filter. The bottom portion may also be integrally formed with a center tube upon which a filter element mounts.
