Removable Filter Element Assembly for Serviceable Fluid Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter systems for fuel cell cooling loops require complete housing replacement for maintenance, as integrated filter elements cannot be removed, leading to inefficiencies and unnecessary resource waste.
Innovation Solution
A filter system with a removable filter element design, utilizing connecting and disassembly elements that allow the filter element to be easily attached and detached from the housing by rotating it along the axial direction, eliminating the need for replacing the entire system during servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter element is integrated into the housing and cannot be removed, then the structural simplicity and reliability are improved, but the ease of repair and resource efficiency deteriorate
Solution Approach 1:
The filter system is divided into two separate components: the housing and the filter element. The filter element can be detached from the housing through a disassembly element that allows rotational movement, enabling easy replacement while maintaining structural integrity during operation.
Solution Approach 2:
The connection between the filter element and housing transitions from a static fixed connection to a dynamic connection that allows controlled rotation. The disassembly element enables the filter element to be rotated and detached when maintenance is needed, while remaining securely attached during normal operation.
2Reliability
If the complete housing has to be replaced during service, then the reliability is maintained, but the loss of substance and resource waste increase
Solution Approach 1:
The filter element is extracted as a separate, replaceable component from the housing. When the filter element becomes clogged or damaged, only the filter element needs to be replaced, not the entire housing, thereby reducing resource waste while maintaining system reliability.
Solution Approach 2:
The filter element is designed to be discarded after a certain service life or when clogged, while the housing is recovered and reused. This selective replacement approach minimizes resource consumption by avoiding replacement of the entire system.
3Ease of operation
If the filter element is easily removable by rotation, then the ease of operation is improved, but the device complexity increases due to connecting and disassembly elements
Solution Approach 1:
The filter element is designed to be self-sufficient with integrated connecting and disassembly elements that enable easy removal without requiring external tools or complex assembly procedures. The rotational mechanism allows the filter element to be easily detached and reattached by the user.

AI summary
A filter system for filtering fluids, in particular a liquid fluid filter system, includes a housing comprising a longitudinal segment having a first opening, and a branching segment having at least one second opening for fluid passage, the housing extending in an axial direction, and the first opening and the at least second opening being separated along the axial direction. The filter system further comprises a filter element comprising a filter body configured to protrude into the housing through the first opening and to filter a fluid flow between the first opening and the at least second opening.
