Oil Filter Aperture for Air Bypass and Filtration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil filtration units face challenges in removing air contaminants without causing oil spillage or incomplete filtration, as conventional methods often result in bypassing filtered oil, which is not treated, and introduce additional costs and components that can fail.
Innovation Solution
The oil filtration unit incorporates an oil filter with a top end surface featuring at least one aperture for air removal, allowing air and a minor amount of oil to bypass through the filter, eliminating the need for external pipes and ensuring all oil is filtered, with filtering material between the aperture and inner filter volume to ensure complete treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional venting devices or external pipes are used to remove air from the housing, then air removal is achieved, but oil spillage occurs or additional components are introduced that can fail and increase cost
Solution Approach 1:
The patent combines the air removal function with the existing oil filter component by integrating apertures into the top end surface of the filter. This merging eliminates the need for separate venting devices or external pipes, thereby removing additional failure points while maintaining air removal capability. The oil filter serves dual purposes: filtering oil and enabling air bypass.
Solution Approach 2:
The patent introduces an intermediary structure - the apertures in the top end surface of the oil filter - that mediates between the air accumulation problem and the oil spillage risk. These apertures provide a controlled pathway for air to escape while the filter media itself acts as a mediator to prevent oil from following the air path, thus resolving the contradiction between air removal and oil containment.
2Object-affected harmful factors
If conventional venting devices or external pipes are used to remove air from the housing, then air removal is achieved, but device complexity and cost increase due to extra components
Solution Approach 1:
The patent merges the air removal function with the existing oil filter component by integrating apertures into the top end surface of the filter. This merging eliminates the need for separate venting devices or external pipes, thereby reducing device complexity and component count while maintaining air removal capability.
Solution Approach 2:
The oil filter is designed to perform multiple functions: it filters oil through its primary filtering action and simultaneously enables air bypass through the apertures in its top end surface. This multi-functionality eliminates the need for dedicated air removal components, simplifying the overall device structure.
3Object-affected harmful factors
If air is removed through the housing upper part, then air collection is reduced, but oil bypasses the filter and is not filtered
Solution Approach 1:
The patent introduces an intermediary structure - the apertures in the top end surface of the oil filter - that mediates between the air removal need and the oil filtration requirement. These apertures provide a controlled pathway for air to escape while the filter media itself acts as a mediator to prevent oil from following the air path, thus resolving the contradiction between air removal and oil containment.
Solution Approach 2:
The patent applies local quality by creating a specific structure with apertures in the top end surface of the oil filter, located at a precise position. This localized feature allows air to bypass the filter media at the top while the rest of the filter continues to filter oil effectively. The selective permeability is achieved through the localized aperture design rather than uniform filtering throughout.

Function Achieved in This Case
This design simplifies the unit, reduces costs, and ensures comprehensive filtration by allowing air and minor oil bypass through the filter, ensuring maximum air removal and minimal oil loss, resulting in a more efficient and cost-effective filtration process.
Implementation Method 1
the top end surface of the oil filter comprises at least one aperture providing fluid/liquid communication between the inner opening of the housing and the inner filter volume
Implementation Method 2

AI summary
An oil filtration unit having an inlet adapted to receive contaminated oil from the surroundings and to release the contaminated oil to an inner opening of the unit, and an outlet adapted to release filtered oil to the surroundings. The inner opening has therein an oil filter for filtering the contaminated oil. The oil filter has a filter inlet defined by an outer surface of the oil filter, an inner filter volume adapted to receive filtered oil, and a filter that provides fluid/liquid communication between the inner filter volume and the outlet of the unit in order to release filtered oil from the inner filter volume. The oil filter has a top and a bottom end surface, where the top end surface of the oil filter has an aperture for providing fluid/liquid communication between the inner opening of the unit and the inner filter volume.
