Filter Element Mounting for Spill-Free Oil and Fuel Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter systems for fluids, particularly oil or fuel, face challenges in safely and easily removing the filter element from the housing without allowing residual raw fluid to enter the fluid tank.
Innovation Solution
A filter element design featuring a first end face with connecting elements that extend longitudinally for secure attachment to the second housing part, utilizing snap-fit or bayonet connections, ensuring easy detachment and preventing residual fluid from entering the tank during replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If snap-fit connections are used for mounting the filter element in the housing, then the filter element can be easily installed and removed, but residual raw fluid may spill into the fluid tank during removal
Solution Approach 1:
The housing is divided into two separate parts: a first housing part that remains connected to the fluid tank, and a second housing part that is detachably connected to the first housing part and contains the filter element. This segmentation allows the filter element to be removed with the second housing part, preventing raw fluid spillage into the tank while maintaining ease of operation.
Solution Approach 2:
The second housing part acts as an intermediary component between the filter element and the fluid tank. By suspending the second housing part from the filter head and connecting it to the first housing part, it creates a controlled removal path that prevents raw fluid from entering the tank during filter element replacement.
2Reliability
If the filter element is securely connected to the housing, then reliable sealing is achieved, but removal of the filter element becomes difficult
Solution Approach 1:
The connection between the housing parts and filter element transitions from static to dynamic. The snap-fit connections provide secure sealing during operation but allow easy detachment when needed. The second housing part can be suspended from the filter head and detached from the first housing part, enabling dynamic reconfiguration for maintenance while maintaining reliability during normal operation.
