Solution Overview

Problem

Existing filter cartridges require significant assembly effort for replacement, leading to high operational costs due to regular clogging or damage, as they must be removed from the partition and compressed air valve system.

Innovation Solution

A filter cartridge design featuring retaining rails with a Y-like configuration and a main body that divides the interior into separate areas, allowing for easy replacement without altering the insert or compressed air valve, using a contact point to prevent gas flow between areas and ensuring airtight connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the filter cartridge is designed with a fixed insert and compressed air valve system, then the structural integrity is improved, but the replacement effort increases significantly

Engineering Contradiction:
Improvestructural integrityVSAvoidreplacement effort
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The filter cartridge is divided into separable components: the housing with integrated retaining rails and the insert with contact points. This segmentation allows the insert to be detached and replaced independently while maintaining the structural integrity of the housing, thereby reducing replacement effort without compromising stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection between the insert and housing transitions from a fixed design to a dynamic, detachable connection using retaining rails and contact points. This enables the system to switch between a stable installed state and an easily replaceable maintenance state, resolving the contradiction between structural integrity and replacement ease.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the filter cartridge requires removal from the partition and compressed air valve, then the cleaning effectiveness is improved, but the operating costs increase

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidoperating costs
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

By segmenting the insert as a separate replaceable component, the system maintains cleaning effectiveness through proper design of the insert structure while enabling quick replacement without full disassembly. This reduces maintenance time and operating costs while preserving the reliability needed for effective cleaning.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The insert is extracted as a separate replaceable component from the housing system. This allows the insert to be removed and replaced independently when needed, maintaining cleaning effectiveness through proper insert design while significantly reducing the time and cost associated with full system disassembly and reassembly.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the retaining rail uses a Y-shaped cross-section, then the guidance function is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improveguidance functionVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The retaining rail combines multiple functions into a single component: structural support, guidance for the insert, and sealing. The Y-shaped cross-section integrates the guidance rails and support structure into one manufactured piece, improving guidance function while managing manufacturing complexity through unified design rather than multiple separate parts.

Inventive Principle:
Principle #5Merging (Combining)
