Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid filters face challenges in servicing due to tight spatial constraints, leading to difficulties in accessing filter elements, messy operations, and issues with dripping and leakage during replacement.
Innovation Solution
A fluid filter assembly with sealing and retention features that maintain a seal between the cover and filter cartridge during removal and replacement, minimizing fluid leakage and providing easier access for servicing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the fluid filter is structured with tight fits to occupy minimal space, then the space occupation is reduced, but the ease of servicing deteriorates
Solution Approach 1:
The filter assembly is divided into separable components: a filter holder containing the filter element, and a cover that can be detached. This segmentation allows the filter element to be accessed and replaced without removing the entire assembly from its mounting location, thus maintaining compact space occupation while improving servicing ease.
Solution Approach 2:
The filter element is extracted as a separate serviceable component within the filter holder. The cover can be removed to access the filter element for replacement, allowing servicing without disturbing surrounding components or requiring significant space, thereby resolving the contradiction between compact design and ease of maintenance.
2Volume of moving object
If the fluid filter is structured with tight fits for minimal space, then the space occupation is reduced, but the messiness during servicing increases
Solution Approach 1:
Sealing elements are incorporated at the interface between the cover and filter holder to prevent fluid leakage during the servicing process. This preliminary anti-action against potential leakage ensures that filter replacement can be performed cleanly without fluid spills or mess, even within compact spatial constraints.
Solution Approach 2:
A seal acts as an intermediary element between the cover and filter holder, maintaining fluid containment during assembly and disassembly operations. This intermediary sealing mechanism prevents direct fluid exposure during servicing, eliminating messiness while preserving the compact design.
3Volume of moving object
If the fluid filter is structured with tight fits, then the space occupation is reduced, but the dripping during removal increases
Solution Approach 1:
Sealing elements are built into the cover and filter holder interface to counteract fluid pressure and prevent dripping during removal operations. This preliminary protective measure ensures that even in compact installations, fluid loss through dripping is minimized or eliminated during servicing.
Solution Approach 2:
The sealing structure provides beforehand protection against fluid leakage by creating a sealed interface between the cover and filter holder. This prior cushioning against potential fluid loss ensures that removal and replacement operations can be performed without dripping, maintaining both compact design and substance conservation.

AI summary
A fluid filter assembly of a filtration system is described. The filter assembly described includes a cover member and a filter cartridge having at least one filter element and a plate member. The plate member includes a seal surface on one side facing the cover member, and a seal surface on another side facing away from the cover member. The seal surface facing the cover member is configured to seal with the cover member, and the seal surface facing away from the cover member configured to seal with another component of the filtration system. The assembly provides a structure that can retain a seal between sealing surfaces of the cover and the filter cartridge, at least while the fluid filter assembly is being serviced, so as to at least minimize fluid dripping and leakage.
