Nested Oil Filter Housing Assembly for Reduced Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oil filter housings in internal combustion engines have multiple distinct flow ports that lack a common structure, leading to multiple points of failure and complicating manufacturing processes.
Innovation Solution
The oil filter housings are designed with an oil filter housing first portion and a second portion that includes a perimeter wall extending orthogonally, with flow ports and holes configured to secure an oil filter and cooler, allowing for improved structural integrity and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a unitary housing component is used, then manufacturing processes are simplified, but multiple distinct points of failure are created due to multiple flow ports lacking a common structure
Solution Approach 1:
The housing is divided into a first housing portion and a second housing portion, each with specific flow ports. The first housing portion includes a first flow port and a second flow port, while the second housing portion includes a third flow port and a fourth flow port. This segmentation allows each portion to be manufactured separately and then assembled, reducing the number of points of failure in each individual component while maintaining manufacturing efficiency.
Solution Approach 2:
The second housing portion is disposed within the first housing portion, creating a nested structure. The perimeter wall of the second housing portion extends toward the first housing portion, and the housing portions are secured together to form a complete housing. This nested arrangement provides structural integrity and reduces the overall number of external flow ports needed.
2Adaptability or versatility
If multiple distinct flow ports are included in a unitary housing, then functional requirements are met, but structural integrity is compromised
Solution Approach 1:
The housing is segmented into two portions, with the first housing portion containing two flow ports and the second housing portion containing two flow ports. Each portion can be optimized for its specific function while maintaining structural strength. The segmentation allows for better distribution of stress and reduced complexity in each individual component.
Solution Approach 2:
The second housing portion is nested within the first housing portion, with the perimeter wall of the second portion extending toward the first portion. This nested structure provides additional structural support and reinforces the overall housing integrity while accommodating multiple flow ports across the two portions.
3Reliability
If an oil filter and cooler are securely integrated, then reliability is enhanced, but assembly complexity increases
Solution Approach 1:
The housing is divided into two portions that can be assembled separately with the oil filter and cooler, then secured together. This segmentation allows for easier assembly of each component individually before final integration, reducing the overall assembly complexity while maintaining secure integration.
Solution Approach 2:
The second housing portion is nested within the first housing portion, creating a compact integrated structure that secures the oil filter and cooler in place. This nested arrangement provides a straightforward assembly process where components are naturally positioned and secured through the nested configuration.
