Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Compressed gas filters face challenges in identifying the type and installation direction of preparation elements, leading to potential confusion during maintenance and increased risk of errors due to the metallic housing acting as a Faraday cage, limiting signal transmission and visibility issues.

Innovation Solution

A through-opening in the housing head allows a functional element to extend outside, providing visual and tactile information about the preparation element type, flow direction, and pressure status, enabling easier identification and facilitating signal transmission and fluid discharge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a metallic housing is used for the filter, then compressive strength and pressure resistance are ensured, but the housing acts as a Faraday cage limiting signal transmission and visibility

Engineering Contradiction:

Improvecompressive strengthVSAvoidsignal transmission

Core Design Contradiction:

StrengthVSLoss of information

Solution Approach 1:

The housing head is segmented by introducing a through-opening that divides the originally continuous metallic structure. This segmentation allows signal transmission through the housing while maintaining the metallic material's compressive strength in the remaining structure. The through-opening creates a pathway for signals without compromising the overall structural integrity of the housing.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A through-opening is extracted from the housing head structure, removing a portion of the metallic material to create a passage. This extracted opening serves as a channel for signal transmission and visual identification, while the remaining metallic structure maintains sufficient compressive strength for pressure containment.

Inventive Principle:

Principle #2Taking out (Extraction)

2Strength

If a metallic housing is used for the filter, then compressive strength is ensured, but visibility and identification of preparation elements become difficult

Engineering Contradiction:

Improvecompressive strengthVSAvoididentification

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The functional element visible through the through-opening can utilize color changes or visual indicators to enhance identification. Different colors or visual patterns on the functional element can indicate the type of preparation element, flow direction, or operational status, making identification easier without requiring opening the housing.

Inventive Principle:

Principle #32Color changes

3Reliability

If preparation elements are installed in a closed filter housing, then sealing and pressure containment are improved, but maintenance and identification become more complex

Engineering Contradiction:

ImprovesealingVSAvoidmaintenance

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The functional element serves as an intermediary between the preparation element inside the housing and the external environment. It transmits information about the preparation element's status, type, and orientation through the housing wall, enabling maintenance personnel to identify and diagnose issues without opening the housing, thus facilitating easier maintenance while maintaining sealing integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The functional element provides visual and tactile feedback about the preparation element's installation status, type, and orientation. This feedback mechanism allows maintenance personnel to verify correct installation and identify issues without opening the housing, simplifying maintenance procedures while maintaining the sealed pressure-containing structure.

Inventive Principle:

Principle #23Feedback

4Ease of manufacture

If identical interfaces are used for all preparation elements, then manufacturing cost is reduced, but identification of specific element types becomes difficult

Engineering Contradiction:

Improvemanufacturing costVSAvoidelement type identification

Core Design Contradiction:

Ease of manufactureVSLoss of information

Solution Approach 1:

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

While the interfaces remain identical for manufacturing efficiency, the functional element provides localized visual differentiation. Different types of preparation elements can have functionally distinct visible features (colors, patterns, shapes) on their functional elements, allowing identification without changing the standardized interface structure.

Inventive Principle:

Principle #3Local quality

AI summary

A compressed air filter includes a housing and a housing head with an inlet and an outlet, wherein a preparation element is arranged in an interior of the housing, and compressed air which is to be prepared flows through the inlet into the preparation element and flows out through the outlet as prepared useful air. The housing head has a through-opening through which, in the state in which the preparation element is used, there extends a functional element connected to the preparation element.
