Oil Filter Element Interface for Mount Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Older oil filter elements with larger pore sizes are not compatible with newer vehicles that have higher emissions standards, as they do not fit the updated oil filter mounts with a linearly outwardly projecting step, leading to incompatibility and potential oil leakage.
Innovation Solution
Designing an oil filter element with a wider neck that is adaptable to both oil filter mounts with and without a step, ensuring it can sealably engage with the base of both types of mounts, allowing it to fit over the step of the first oil filter mount and on the second oil filter mount without a step, while preventing smaller pore size elements from fitting over the step.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an oil filter element with a smaller pore size is used to meet higher emissions standards, then oil quality and contaminant removal are improved, but compatibility with older oil filter mounts is lost
Solution Approach 1:
The oil filter element is designed with a neck having an outer diameter that exceeds the outer diameter of the outwardly projecting step, enabling the same filter element to be installed on both older mounts (without step) and newer mounts (with step). This universal design allows a single filter element to serve multiple vehicle configurations and emission standards.
2Adaptability or versatility
If an oil filter element with a larger pore size is used for compatibility with older mounts, then mount compatibility is improved, but oil quality and contaminant removal are reduced
Solution Approach 1:
The filter element's neck is designed with sufficient clearance relative to the outwardly projecting step, allowing the element to fit over the step while maintaining its smaller pore size for high-quality filtration. This enables the element to be universally compatible with both older and newer mount types while meeting higher emissions standards.
3Adaptability or versatility
If the neck outer diameter is increased to fit over the outwardly projecting step, then adaptability to newer mounts is improved, but the risk of oil leakage may increase
Solution Approach 1:
An outwardly projecting step is provided on the oil filter mount that acts as an intermediary sealing surface. The step engages with the oil filter element to create a seal that prevents oil leakage, while still allowing the element to fit over it due to the carefully designed clearance relationship between the neck outer diameter and step outer diameter.
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
Ensures compatibility and effective filtration for vehicles with varying emissions standards by allowing the oil filter element to fit multiple mount configurations, enhancing oil quality and preventing leakage issues.
Implementation Method 1
Oil filter elements are mounted within the oil filter and are made up of porous media. As oil passes through the oil filter elements in the oil filter, contaminants become entrained in the filter while clean oil passes through the pores

AI summary
Various systems are provided for an interface between an oil filter element and an oil filter mount of an oil filter. In one embodiment, an oil filter comprises an oil filter element adapted to be fittable over an outwardly projecting step of a first oil filter mount and fittable on a second oil filter mount without an outwardly projecting step, the oil filter element having an opening adapted to sealably engage with a base of the first oil filter mount and a base of the second oil filter mount.
