Solution Overview

Problem

The conventional manufacturing of purification columns is costly due to the need for multiple moulding tools and complex machining operations, especially when producing a range of columns with varying pipe connections and flow capacities, and this becomes more problematic when multiple columns are close-coupled together.

Innovation Solution

The design integrates the inlet and outlet ports directly into the annular wall containing the purifying component, reducing the number of components and machining required, allowing for a more cost-effective production of purification columns that can be easily close-coupled, with the option of single-bore or multi-bore configurations that emulate a series or parallel arrangement of columns.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional two-piece moulded constructions with separate top head manifolds and filter bowls are used, then the purification column can be manufactured with standardized components, but the manufacturing cost increases due to the large number of moulding tools and complex machining operations required

Engineering Contradiction:
Improvemanufacturing costVSAvoidnumber of components
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges the top head manifold and filter bowl into a single integrated column body that is moulded as one piece. This eliminates the need for separate components and their associated mating connections, thereby reducing the number of moulding tools required and simplifying the manufacturing process while lowering overall manufacturing cost

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If individual top head manifolds are connected to filter bowls of varying length with separate moulding tools, then columns with varying pipe connections and flow capacities can be produced, but the manufacturing cost increases due to the large number of moulding tools necessary

Engineering Contradiction:
Improvevarying pipe connections and flow capacitiesVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The integrated column body design serves multiple functions: it provides the structural housing, contains the purifying component, and incorporates inlet/outlet ports with various connection configurations. By making the column body universal and adaptable to different purifying components and connection types, the design eliminates the need for multiple specialized moulding tools while maintaining versatility

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

3Manufacturing precision

If post-moulding machining operations are performed to provide male and female connections and purifying component locators, then accurate mating connections can be achieved, but the manufacturing cost and production time increase

Engineering Contradiction:
Improvemating connection accuracyVSAvoidmanufacturing cost
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

Solution Approach 1:

The patent incorporates the mating connections and purifying component locators directly into the moulded column body structure before final assembly. By pre-forming these features during the moulding process rather than adding them through post-moulding machining, the design achieves the required precision while eliminating costly and time-consuming machining operations

Inventive Principle:
Principle #10Preliminary action

AI summary

A purification column is provided in which fluid is purified by flow through a purifying component. The column includes an annular wall defining a bore which, in use, contains the purifying component. The column further includes an inlet port to the bore comprising a first aperture through the annular wall, the inlet port being adjacent one end of the column. The column further includes an outlet port from the bore comprising a second aperture through the annular wall, the outlet port being adjacent the same end of the column as the inlet port. The column further includes a flow guidance device within the bore and removably connected to the inlet and outlet ports for guiding the fluid to the purifying component from the inlet port and for guiding the fluid from the purifying component to the outlet port. The flow guidance device maintains separation of the fluid flows to and from the purifying component.
