Solution Overview

Problem

Filtration systems face challenges in efficiently servicing membrane modules, particularly those located deep within arrays, due to the vertical positioning of manifolds and overhead supporting frames, leading to increased downtime and costs when accessing and maintaining individual modules.

Innovation Solution

The filtration module assembly features a novel manifold arrangement with offset fluid control manifolds and improved header housings that allow for easier access and maintenance of membrane modules, enabling modules to be serviced without disrupting the entire system, using a combination of offset manifolds and self-supporting module designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If vertical positioning of manifolds and overhead supporting frames is used, then structural support is provided, but access and maintenance of individual modules becomes difficult

Engineering Contradiction:
ImproveAccess and maintenance of individual modulesVSAvoidOverhead supporting frames and vertical manifold arrangement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system is divided into independent filtration modules that can be individually accessed and maintained. Each module is separated by spacing that allows service access without disrupting other modules, enabling segmented maintenance rather than system-wide shutdowns.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The manifold arrangement transitions from a vertical overhead configuration to a horizontal offset configuration at the module level. This dimensional change allows service personnel to access modules from the side rather than requiring overhead access, fundamentally changing the maintenance approach.

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

2Productivity

If modules are closely arranged in arrays, then space efficiency is improved, but servicing individual modules requires taking entire system offline

Engineering Contradiction:
ImproveSpace efficiency of module arrangementVSAvoidSystem downtime during module servicing
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The filtration system is segmented into independently serviceable modules with sufficient spacing between them. This spacing creates service corridors that allow personnel to access and maintain individual modules without removing or disturbing adjacent modules, enabling selective maintenance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Offset manifolds are positioned as intermediary components that provide fluid distribution while maintaining clearance between modules. These manifolds are configured to allow tool access and module removal without requiring complete system disassembly, serving as mediators between compact arrangement and serviceability.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If overhead supporting frames are used, then structural stability is achieved, but maintenance costs increase

Engineering Contradiction:
ImproveStructural stability of filtration systemVSAvoidMaintenance cost and complexity
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The support structure is segmented into module-specific mounting features integrated into the header housing rather than requiring a continuous overhead frame. Each module can be independently mounted and dismounted, reducing the complexity and cost of the supporting infrastructure while maintaining structural stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The overhead supporting frame is extracted and replaced with integrated mounting features on the header housing. This removes the complex overhead structure while retaining the essential support function through simpler, module-level mounting mechanisms that reduce maintenance requirements.

Inventive Principle:
Principle #2Taking out (Extraction)
