Solution Overview

Problem

Existing filtration systems require a large amount of space due to the need to position the discharge line away from the filter cartridge to prevent damage during fluid flow, especially during cleaning, which increases the system's footprint and complexity.

Innovation Solution

A line arrangement where the filtrate collecting line is integrated at the level of the filtrate area, with outlet openings only at a gap area connected by a tapering connecting element, shielding the filter from flow forces and allowing for a compact design by positioning the filtrate collecting line transversely to the feed line, thereby reducing space requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the discharge line is positioned away from the filter cartridge to prevent damage during fluid flow and cleaning, then the filter is protected from flow-induced stress, but the system requires a relatively large amount of space

Engineering Contradiction:
Improvefilter protection from flow damageVSAvoidsystem footprint
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The discharge line is repositioned from a lateral arrangement to a longitudinal arrangement within the feed line itself. The outlet openings are positioned in the filtrate region of the feed line, allowing the discharge line to integrate with the feed line structure rather than requiring separate lateral space. This dimensional reconfiguration protects the filter while minimizing system footprint.

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

Solution Approach 2:

The discharge line is nested within the feed line structure by positioning outlet openings in the filtrate region of the feed line. The connecting element integrates the discharge line to the feed line, creating a compact nested arrangement where the discharge functionality is embedded within the feed line rather than requiring external lateral positioning.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If the filtrate collecting line is positioned away from the filter during cleaning operations, then the filter is protected from cleaning flow stress, but the system complexity and space requirements increase

Engineering Contradiction:
Improvefilter protection during cleaningVSAvoidline arrangement complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The discharge line is merged with the feed line by positioning outlet openings in the filtrate region of the feed line. This integration eliminates the need for separate lateral discharge lines and reduces overall system complexity while maintaining the protective function during cleaning operations.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connecting element acts as an intermediary that integrates the discharge line to the feed line at the filtrate region. This intermediary component enables the discharge functionality while simplifying the overall line arrangement and reducing system complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the outlet openings are positioned in the feed line away from the filter, then the filter is protected from flow suction damage, but the filtrate cannot be removed immediately after filtering

Engineering Contradiction:
Improvefilter protection from flow suctionVSAvoidfiltrate removal efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The outlet openings are positioned in the filtrate region of the feed line, utilizing the longitudinal dimension of the feed line rather than requiring lateral displacement. This positioning enables immediate filtrate removal while protecting the filter from flow suction damage.

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

Solution Approach 2:

The outlet openings are positioned in the filtrate region before the filtrate collects, enabling immediate removal of filtrate as it is produced. This preliminary positioning prevents filtrate accumulation and maintains continuous filtration efficiency.

Inventive Principle:
Principle #10Preliminary action
