In-line Filter Assembly Segmentation for Serviceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-line filter assemblies face challenges in replaceability, serviceability, and environmental impact, particularly in tight under-hood automotive conditions, where filter element replacement often results in unnecessary part disposal and increased costs.
Innovation Solution
The design features an in-line filter assembly with a detachable inlet and outlet duct housing system, allowing for the filter element to be replaced without removing the intermediate housing, utilizing seals and connectors to maintain integrity and prevent fluid bypass, enabling cost savings and reduced environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the filter element is made replaceable in traditional in-line filter assemblies, then serviceability is improved, but the intermediate housing must be removed which increases complexity and time for servicing
Solution Approach 1:
The housing is segmented into three distinct sections: inlet duct housing, intermediate housing, and outlet duct housing. The inlet duct housing can be detached from the intermediate housing while the outlet duct housing remains attached, allowing the filter element to be accessed and replaced without removing the intermediate housing. This segmentation enables independent access to the filter element while maintaining the structural integrity of the intermediate housing.
2Ease of repair
If the filter element is made replaceable, then serviceability is improved, but more parts must be discarded which increases cost and environmental impact
Solution Approach 1:
The detachable inlet duct housing allows the filter element to be replaced while keeping the intermediate housing and outlet duct housing in place. This means only the inlet duct housing needs to be removed and potentially discarded, rather than the entire intermediate housing assembly, thereby reducing the number of parts that must be discarded and lowering servicing costs and environmental impact.
3Ease of repair
If seals are made removable to facilitate filter replacement, then serviceability is improved, but sealing integrity may be compromised
Solution Approach 1:
The sealing system is segmented into multiple seals positioned at different locations: a first seal between the inlet duct housing and intermediate housing, a second seal between the intermediate housing and outlet duct housing, and a third seal within the intermediate housing. When the inlet duct housing is detached for filter replacement, only the first seal is affected. The second and third seals remain intact and continue to provide sealing integrity, allowing the filter to be replaced while maintaining overall sealing reliability.

AI summary
An in-line filter assembly includes an inlet duct housing, an intermediate housing, and an outlet duct housing, and seals a filter element in the intermediate housing and facilitates removal and replacement thereof.
