Solution Overview

Problem

Existing membrane filtration systems require costly and complex support structures that need redesign for varying system sizes, leading to inefficient manufacturing and transportation due to separate production of module arrays and support frames.

Innovation Solution

An integrated support frame system that can be easily adapted to accommodate different sizes and capacities by positioning inverted U-shaped or rectangular frames between membrane modules, connected to manifold blocks, allowing for a compact, single-unit construction and transportation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If separate external frames are built around module arrays, then structural support is provided, but manufacturing complexity and cost increase

Engineering Contradiction:
Improvestructural supportVSAvoidmanufacturing complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The support frame and module array are merged into a single integrated unit. The frame members are positioned between and connected to the membrane modules, creating a unified structure that provides support while eliminating separate manufacturing and assembly processes.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If separate external frames are built around module arrays, then structural support is provided, but transportation efficiency decreases due to double handling

Engineering Contradiction:
Improvestructural supportVSAvoidtransportation time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

By integrating the support frame with the module array into a single unit, the invention eliminates the need for separate transportation of frame and modules. The complete filtration system can be shipped as one compact unit, reducing double handling and transportation time.

Inventive Principle:
Principle #5Merging (Combining)

3Strength

If support structures are designed for specific module array sizes, then structural integrity is maintained, but adaptability to varying system sizes decreases

Engineering Contradiction:
Improvestructural integrityVSAvoidadaptability to varying sizes
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The support frame is divided into multiple individual frame members that can be independently positioned and connected to specific modules. This segmentation allows the same frame design to be configured for different module array sizes by simply adding or removing members, while maintaining structural integrity through consistent connection methods.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The frame members are designed with universal connection capabilities that can interface with multiple module types and configurations. The same basic frame member design can serve different structural roles and adapt to various system sizes, providing multi-functionality and versatility.

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

4Loss of time

If complete filtration systems are shipped as single units, then transportation efficiency improves, but system size constraints must be met

Engineering Contradiction:
Improvetransportation efficiencyVSAvoidsystem size
Core Design Contradiction:
Loss of timeVSVolume of moving object

Solution Approach 1:

The module arrays are nested within the support frame structure, with frame members positioned between and connecting to the modules. This nested arrangement creates a compact integrated unit that maximizes space utilization and meets shipping size constraints while maintaining the completeness of the filtration system.

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A module arrangement (5) according to an embodiment of the invention consists of a plurality of membrane modules (6) arranged in a two dimensional array (7) and extending between upper and lower block-type manifolds (8) and (9), respectively. The array of modules is further divided into sub-groups of modules (10) separated from each other by space (11) extending transversely across the membrane array (7). An integrated support frame (12) is positioned in the space (11) between the sub-groups (10) and is fixed to the upper and lower manifold blocks (8) and (9) to form an integrated support structure within the module array (7).
