Solution Overview
Problem
Traditional oil filter assemblies with single-piece housings are cumbersome, expensive, and time-intensive to manufacture, requiring disassembly for filter element replacement, limiting interchangeability of parts and tolerances.
Innovation Solution
A modular filter assembly design featuring a housing with a detachable collar and removable locking element, allowing for selective access to the filter media without disassembling the outer housing, using threaded, welded, press-fit, or adhesive connections, enabling easy replacement and interchangeability of components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single piece housing with integrally formed collar is used, then the filter assembly structure is simplified, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The filter assembly is divided into separate components: a housing and a collar that can be manufactured independently. The collar is attached to the housing through various connection methods (threaded, welded, press-fit, or adhesive), allowing each part to be optimized for its specific function while simplifying the overall manufacturing process compared to producing a single integrated piece.
2Stability of the object's composition
If a single piece housing with integrally formed collar is used, then the structural integrity is improved, but the manufacturing precision and tolerance control become difficult
Solution Approach 1:
By separating the housing and collar into independent components, each part can be manufactured with standard tolerances and then assembled together. This segmentation allows for better control of individual part dimensions and facilitates quality inspection, whereas an integrated design would require extremely tight tolerances across the entire structure.
3Reliability
If a single piece housing with integrally formed collar is used, then the filter assembly is more robust, but the interchangeability of subparts is limited
Solution Approach 1:
The collar is designed as a separate, standardized component that can be attached to different housing configurations. This universal collar design enables the same collar to be used across multiple filter assemblies with varying housing lengths and filter media types, improving part interchangeability and reducing inventory complexity while maintaining structural robustness.
4Ease of repair
If traditional filter housing disassembly is required for filter element removal, then the filter assembly can be serviced, but the time required for maintenance increases significantly
Solution Approach 1:
The collar is designed as a removable component that can be detached from the housing without disassembling the entire filter assembly. This allows the filter element to be accessed and replaced by simply removing the collar, significantly reducing maintenance time compared to traditional designs that require complete housing disassembly.
Solution Approach 2:
The collar incorporates a removable locking element that can be selectively locked or unlocked to provide controlled access to the filter element. This dynamic locking mechanism allows the collar to transition between secured and accessible states, enabling quick filter element replacement while maintaining structural integrity during operation.
5Ease of repair
If tools and disassembly procedures are required for filter replacement, then the filter housing can be serviced, but the operational complexity increases
Solution Approach 1:
The filter assembly is segmented into a housing and a removable collar with locking element. This segmentation allows the collar to be removed and serviced independently without requiring disassembly of the housing, simplifying the overall maintenance procedure and reducing the tools and steps required for filter element replacement.
Solution Approach 2:
The removable locking element provides a dynamic mechanism that allows the collar to be easily locked during operation and quickly unlocked for maintenance. This dynamic locking system eliminates the need for complex disassembly procedures and specialized tools, enabling simple filter element replacement through a straightforward lock/unlock process.
