Filter Cartridge Flange with Longitudinal Support Section
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Filter cartridges in mobile applications, such as suction excavators, face challenges with complex structures due to strong vibrations and bending forces when swiveled, making installation laborious and requiring additional support constructions that can lead to dust bridges and increased weight.
Innovation Solution
A filter cartridge design featuring a radial flange with a support section extending in the lengthwise direction, which absorbs bending forces and serves as a centering aid, allowing for easy installation and eliminating the need for additional support constructions, while maintaining a large filter surface area and air-tight connection through integral bonding with the filter medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the holder containing the filter cartridges is swiveled from vertical to horizontal position, then the filter cartridge can be installed in mobile applications, but strong forces act on the flange and holder making installation laborious
Solution Approach 1:
The flange is segmented into two functional parts: a radial flange for mounting and a support section extending in the lengthwise direction. This segmentation allows the support section to absorb bending forces during swiveling while the radial flange provides stable mounting, resolving the contradiction between mobile adaptability and installation ease.
Solution Approach 2:
The support section extends in the lengthwise direction (longitudinal dimension) rather than only radially, adding structural reinforcement in the dimension that experiences bending forces during swiveling. This dimensional extension absorbs the bending moments and reduces installation difficulty while maintaining mobile application versatility.
2Strength
If additional support constructions are added to withstand bending forces, then the filter cartridge can handle mobile applications, but the structure becomes complex and weight increases
Solution Approach 1:
The support function is merged into the flange itself by extending the support section integrally from the radial flange. This eliminates the need for separate support constructions, reducing structural complexity while maintaining high bending force resistance through the integrated support section.
Solution Approach 2:
The flange is designed to perform multiple functions: radial mounting (radial flange) and bending force absorption (support section). This multi-functionality eliminates the need for additional dedicated support structures, reducing overall structural complexity while maintaining strength.
3Strength
If additional support constructions are added to withstand bending forces, then the filter cartridge can handle mobile applications, but the weight increases
Solution Approach 1:
The support function is merged into the flange itself, eliminating the need for separate support constructions. This integration reduces the total material required and thus the weight, while maintaining bending force resistance through the strategically designed support section.
Solution Approach 2:
The unnecessary additional support constructions are extracted/removed from the design. The support function is achieved through the extended support section of the flange itself, eliminating redundant structural elements and reducing overall weight.

AI summary
A filter cartridge has a filter medium that is provided at least on an end face with a flange that serves for the installation of the filter cartridge in a filter arrangement, whereby the flange has a radial flange and a support section, whereby the support section extends in the lengthwise direction of the filter cartridge.
