Oil Filter Adaptor With Through-Aperture for Pre-Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inverted spin-on oil filters in internal combustion engines pose a challenge during maintenance, as oil trapped in the filter housing can spill when removed, leading to unwanted oil overflow and splashing.
Innovation Solution
An oil filter adaptor with a neck featuring a through-aperture that allows pre-discharge of trapped oil before filter removal, combined with a deflector to minimize splashing, is designed to engage the oil filter and facilitate controlled oil flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If an inverted spin-on oil filter is used to save package space and simplify oil flow passage design, then the package space is reduced and design is simplified, but oil trapped in the filter housing spills and splashes when the filter is removed for maintenance
Solution Approach 1:
The patent applies preliminary action by providing a drain passage that allows oil to be discharged from the filter housing before the filter element is removed. The drain passage includes a drain hole positioned at the lowest point of the filter housing, enabling trapped oil to flow out through the drain passage and into a collection container before maintenance personnel handle the filter element, thereby preventing oil spill and splash during maintenance operations
Solution Approach 2:
The patent uses an intermediary approach by introducing a drain passage as a mediating structure between the filter housing and the external environment. This drain passage acts as a controlled channel that directs oil flow away from the filter element and mounting area, preventing uncontrolled spill and splash while maintaining the inverted mounting orientation benefits
2Device complexity
If the oil filter is mounted in an inverted position with entry and exit openings facing down, then package space is reduced and oil flow passage design is simplified, but oil trapped within the filter housing suddenly flows through the openings and causes spills
Solution Approach 1:
The drain passage provides preliminary action by enabling oil discharge before filter element removal. The drain hole is positioned at the lowest point of the filter housing, and the drain passage extends downward to allow oil to flow out into a collection container before the filter element is handled, ensuring safe maintenance operation
Solution Approach 2:
The patent segments the oil flow path by creating a separate drain passage distinct from the main oil flow passages. This segmentation allows independent control of oil discharge from the filter housing, separating the maintenance operation from potential oil spill hazards
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces oil splashing and overflow by allowing pre-discharge of oil through the through-aperture, providing ample time for oil to flow out and minimizing spills during filter maintenance.
Implementation Method 1
oil trapped within the volume of the filter housing may suddenly flow through the openings of the filter and causes spills

AI summary
The present invention in one or more embodiments provides an oil filter adaptor to engage an oil filter, where the oil filter adaptor includes a base and a neck extending from the base in a first direction and to engage the oil filter, the neck including a wall defining therein a passageway extending at least partially in the first direction, the wall defining thereupon a through-aperture extending in a wall thickness direction. The oil filter adaptor of the present invention may pre-discharge oil flowing out thereof when the oil filter is removed, avoiding oil splashing due to an otherwise large efflux of oil in a very short period of time.
