Filter Element Torque Transmission via Toothed Support Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter elements for motor vehicles and industrial motors face issues with torque transmission during removal, which can cause mechanical loading and damage to the filter medium due to sticky residues and deposits, leading to difficulties in detachment from the filter housing.
Innovation Solution
The implementation of a toothed connection between terminal bodies and a support body for torque transmission, allowing for rotation without significant mechanical loading on the filter medium, using a toothing mechanism that transmits torque from one terminal body to another via a suitable connection, eliminating the need for additional tools or adhesive processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If torque is applied to rotate the filter element for removal, then the filter element can be detached from the filter housing, but the filter medium becomes mechanically loaded and may be torn or damaged
Solution Approach 1:
The filter element is segmented into functionally distinct components: the terminal body for torque application, the support body for structural support, and the filter medium for filtration. The toothing mechanism is provided only on the terminal body and support body, excluding the filter medium, thereby isolating the mechanical torque transmission path from the filter medium and preventing its damage during removal operations.
Solution Approach 2:
The support body acts as an intermediary between the terminal body and the filter medium. The toothing mechanism on the support body transmits torque from the terminal body while the support body itself absorbs the mechanical stresses, preventing direct transmission of damaging forces to the filter medium.
2Ease of operation
If the filter element is rotated to remove deposits and sticky residues, then detachment from the filter housing is facilitated, but the fused connection between end disks and filter medium experiences increased mechanical loading
Solution Approach 1:
The fused connection between the end disk and filter medium is segmented from the torque transmission path. The toothing mechanism on the support body provides an alternative mechanical engagement for torque transmission, isolating the fused weld connection from rotational stresses and preventing damage during the detachment process.
3Strength
If a toothing connection is added for torque transmission, then the filter medium is protected from mechanical loading, but the device complexity increases
Solution Approach 1:
The toothing mechanism is merged with the existing terminal body and support body structures. The toothing is integrated into the terminal body's outer circumference and the support body's inner circumference, combining the torque transmission function with the existing structural components rather than adding separate, complex mechanisms.
Solution Approach 2:
The terminal body and support body serve multiple functions: structural support, torque transmission through toothing, and maintaining the filtered fluid passage. This multi-functionality reduces the need for additional specialized components, thereby limiting the increase in device complexity while achieving protection of the filter medium.

AI summary
A filter element of a filter system for filtering fluids has a filter medium with end faces. Terminal bodies, one each, are connected to one of the end faces of the filter medium, respectively. A support body extends between the terminal bodies. A first terminal body is connected by a toothed connection to the support body for transmitting a torque from the first terminal body onto the support body and from the support body onto the first terminal body.
