Filter Element Removal Features for Engine Filtration Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter assemblies for internal combustion engines require complex disassembly procedures to remove and service the filter elements, which can be time-consuming and inefficient.
Innovation Solution
A filtration assembly design featuring a filter housing with a base and a cover, where the filter element is removably installed within the base, and the endplate of the filter element includes engagement features that interact with retainer features on the cover, allowing for simultaneous removal of the filter element when the cover is separated from the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the filter element is permanently fixed within the filter housing, then the structural stability is improved, but the ease of removal and servicing deteriorates
Solution Approach 1:
The filter assembly is segmented into distinct components: the filter housing, the filter element, and the retainer assembly. The retainer assembly can be independently removed from the filter housing, and the filter element can be independently removed from the retainer assembly. This segmentation allows the filter element to be easily accessed and serviced without removing the entire filter housing.
Solution Approach 2:
The connection between components transitions from static/permanent to dynamic/removable. The retainer assembly provides a removable connection between the filter housing and filter element, allowing the system to switch between a stable installed state and an accessible service state. The engagement features and retainer features create a secure but removable connection.
2Ease of repair
If the filter element is made removable from the filter housing, then the ease of servicing is improved, but the device complexity increases
Solution Approach 1:
The retainer assembly merges multiple functions into a single component: it serves as both the mounting structure for the filter element and the removable connection interface with the filter housing. The engagement features on the retainer assembly simultaneously provide structural support and removable attachment, reducing the need for separate fastening mechanisms.
Solution Approach 2:
The retainer assembly performs multiple functions: it secures the filter element in place, provides a removable interface with the filter housing, and facilitates easy removal and installation of the filter element. This multi-functionality reduces the overall complexity by eliminating the need for separate components for each function.
3Stability of the object's composition
If complex disassembly procedures are required to remove the filter element, then the structural integrity is improved, but the maintenance time increases
Solution Approach 1:
The retainer assembly is pre-configured with engagement features that automatically engage with the filter element during installation. This preliminary arrangement ensures structural integrity is established before servicing is needed, allowing for quick removal without requiring complex disassembly procedures. The retainer assembly is designed to be removed as a single unit with the filter element.
Solution Approach 2:
The retainer assembly extracts the complex disassembly procedure by providing a simple removal mechanism. The engagement features and retainer features allow the entire retainer assembly with the attached filter element to be removed from the filter housing in a single action, eliminating the need for multiple disassembly steps while maintaining structural integrity during operation.

AI summary
A filtration assembly includes a filter housing and a filter element. The filter housing includes a base and a cover including an underside having one or more retainer features. The cover is removably coupled to the base. The filter element is removably installed within the base when the cover is coupled to the base. The filter element includes filter media and an endplate coupled to one end of the filter media. The endplate includes an outer perimeter and one or more engagement features protruding from the outer perimeter. The one or more engagement features engage the one or more retainer features in the cover upon installation of the endplate into the cover, thereby coupling the endplate to the cover.
