Eccentric Filter Element End Disk for Tight Space Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional liquid filters face challenges in adaptability to limited spatial conditions due to the space occupied by inlet and outlet fittings, restricting the integration of additional elements like sensors or heating connections.
Innovation Solution
A filter element with an annular, rotationally symmetrical filter medium sealed by an off-center end disk, allowing for a central space creation by positioning the fittings off-axis, enabling better integration with filter heads and accommodating add-on elements in tight spaces through a pipe fitting and elastomer rings for secure assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If inlet and outlet fittings are arranged on the filter head, then liquid flow connection is achieved, but the available space on the filter head is reduced and adaptability to limited spatial conditions is restricted
Solution Approach 1:
The patent applies asymmetry by positioning the inlet and outlet fittings at off-center locations on the filter head rather than symmetrically. Specifically, the inlet fitting is disposed at an first off-center location and the outlet fitting at a second off-center location, creating asymmetric spatial distribution that optimizes space utilization and allows additional elements to be mounted on the filter head.
2Adaptability or versatility
If fittings are centrally arranged on the filter head, then connection is simplified, but the filter head has little room for mounting add-on elements such as sensors or heating connections
Solution Approach 1:
The patent uses asymmetric positioning of fittings to create space for add-on elements. The inlet and outlet fittings are deliberately placed at off-center locations, which simplifies the overall configuration while simultaneously creating available space on the filter head for mounting additional components such as sensors or heating connections.
3Adaptability or versatility
If the filter element uses conventional central openings for fittings, then manufacturing is straightforward, but the filter element cannot be optimized for tight installation spaces
Solution Approach 1:
The patent implements asymmetric fitting positions that are optimized for tight installation spaces. The inlet and outlet fittings are positioned at specific off-center locations that allow the filter element to be compact while still maintaining ease of manufacture through standard manufacturing processes.

AI summary
A filter element for a liquid filter, especially a fuel filter, having an annular, rotationally symmetrical filter medium closed on at least one axial end by an end disk to sealingly separate an exterior space surrounding the the filter medium from an interior space inside the filter medium, with a connecting opening provided in the end disk such that the opening is arranged eccentrically of the axis of the filter medium, and a filter system in which such a filter element is disposed.
