Solution Overview
Problem
Existing self-cleaning oil filter mounting structures, such as those described in JP Pat. No. 2006/112435, are prone to frequent failure due to their configuration, which affects the reliability and durability of oil filter systems in internal combustion engines.
Innovation Solution
A self-cleaning oil filter housing design featuring a hollow elongated body with strategically positioned first and second flanges having through holes along tangential directions at a predetermined angle, along with a rib portion extending between them, and a bracket member with corresponding threaded holes, ensuring secure mounting and preventing slippage through frictional contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional mounting structure with bracket and fasteners is used, then the oil filter can be mounted on the engine body, but the mounting structure is prone to frequent failure due to its configuration
Solution Approach 1:
The mounting structure is divided into separate functional elements: the hollow elongated body with integrated flanges and through holes forms one segment, while the bracket member with threaded holes forms another. This segmentation allows each part to be optimized independently and assembled through precise alignment of the through holes with threaded holes, reducing failure points.
Solution Approach 2:
The flanges with through holes are integrated directly into the hollow elongated body of the oil filter housing, merging the mounting function into the filter housing itself. This eliminates the need for separate mounting brackets attached to the filter, simplifying the overall structure while improving reliability through fewer connection points.
2Strength
If multiple internally threaded holes are provided in the housing for fastener engagement, then the housing can be securely mounted, but the structural complexity and potential failure points increase
Solution Approach 1:
The first and second flanges are positioned asymmetrically on the hollow elongated body, with through holes oriented at a predetermined angle relative to each other. This asymmetric arrangement provides secure mounting while simplifying the housing structure compared to symmetric multi-hole configurations, as it requires fewer threaded insertions and reduces structural complexity.
3Ease of operation
If the mounting structure is simplified for easy installation, then assembly becomes easier, but the reliability and resistance to failure may be compromised
Solution Approach 1:
The through holes are pre-positioned in the flanges at specific orientations and locations during manufacturing. This preliminary action ensures that during installation, the bracket member can be directly aligned and secured without complex alignment procedures, maintaining ease of installation while ensuring reliable mounting through pre-optimized hole positions.
