Twisted Round Filter Element for Flexible Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing round filter elements with longitudinally extending cross-sectional shapes face challenges in adapting to different installation situations without significant modification, as they often require precise congruence with filter housings, limiting flexibility and installation options.
Innovation Solution
The filter medium body is twisted about its longitudinal axis, allowing the axially opposed end faces to be angularly displaced relative to each other, enabling adaptation to various installation conditions while maintaining high filtration performance through a non-rotational symmetry configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the filter medium body has a constant cross-sectional shape, then the manufacturing precision is improved, but the adaptability to different installation situations deteriorates
Solution Approach 1:
The filter medium body is designed with a twisted configuration where the cross-sectional shape changes along the longitudinal axis, creating asymmetric end faces. This asymmetric design allows the filter element to adapt to different installation situations and filter housing configurations without requiring precise congruence, while still maintaining manufacturability through the twisted structure.
Solution Approach 2:
The filter medium body incorporates a twist that creates a dynamic variation in cross-sectional shape along its length. The end faces are angularly displaced relative to each other, allowing the structure to flexibly accommodate different installation spaces and orientations while maintaining structural integrity and filtration performance.
2Adaptability or versatility
If the filter medium body is twisted to enable adaptation, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The twist creates asymmetric end faces that are angularly displaced relative to each other, enabling the filter element to adapt to different installation situations. This asymmetric configuration allows the same filter medium body to fit into various filter housing designs without requiring additional modifying expenditure.
Solution Approach 2:
The twisted filter medium body design provides universal adaptability across different installation scenarios. The same twisted structure enables the filter element to be installed in various orientations and positions within different filter housings, making it a multi-functional component that can accommodate diverse application requirements.

AI summary
A round filter element has a filter medium body with a wall to be flowed through by a fluid to be purified radially relative to a longitudinal axis of the filter medium body. The filter medium body has a longitudinally extending cross-sectional shape in a direction transverse to the longitudinal axis. The filter medium body has a first end face and a second end that are axially oppositely positioned relative to each other in a direction along the longitudinal axis of the filter medium body. A first end disk and a second end disk are arranged at the first and second end faces, respectively, and have the same cross-sectional shape. The filter medium body has a twist by being twisted about the longitudinal axis such that the axially oppositely positioned first and second end faces of the filter medium body are angularly displaced relative to each other.
