Solution Overview

Problem

Existing filtration systems experience significant pressure drops, particularly in high-pressure applications, leading to inefficiencies and increased energy consumption, especially when fluid is not returned to a reservoir.

Innovation Solution

A filter assembly design featuring an inside-out flow with a cylindrical housing, angled peripheral outlet, and an upper endcap assembly with a diverter plate and struts that minimize pressure drop by directing fluid flow efficiently through a conical outlet and incorporating a bypass valve structure with aligned channels and a diverter plate.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If conventional filter assemblies are used, then filtration function is provided, but pressure drop is significant (11 psid and 7 psid)

Engineering Contradiction:
Improvepressure dropVSAvoidflow rate
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The patent inverts the conventional flow direction by implementing an inside-out flow element where fluid enters through the center and exits through the periphery, rather than the traditional outside-in approach. This inversion, combined with the angled peripheral outlet positioned at approximately 45 degrees, optimizes flow dynamics and minimizes pressure drop while maintaining effective filtration.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The patent introduces a three-dimensional angled peripheral outlet structure positioned at approximately 45 degrees relative to the housing axis, creating a more efficient flow path in multiple dimensions. This spatial arrangement reduces flow resistance and pressure drop compared to conventional linear flow paths.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of energy

If filter assembly minimizes pressure drop, then energy consumption is reduced, but structural complexity increases with diverter plate and strut assembly

Engineering Contradiction:
Improveenergy consumptionVSAvoidupper endcap assembly structure
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The upper endcap assembly serves multiple functions: it supports the diverter plate, provides structural closure, and integrates the strut assembly for bypass valve support. The diverter plate itself performs dual functions by directing flow and supporting the bypass valve mechanism, reducing the need for separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the diverter plate with the strut assembly and bypass valve support structure into an integrated upper endcap assembly. This merging of functions reduces the number of separate parts while achieving the desired flow optimization and pressure drop minimization.

Inventive Principle:
Principle #5Merging (Combining)
