Dump-able Fuel Filter Cap Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel system filters do not effectively address the need for frequent cleaning and reuse, leading to reduced filter life and increased maintenance costs due to the inability to efficiently remove and dispose of contaminants.
Innovation Solution
A dump-able dust filter design featuring a filter assembly seated within a filter body, enclosed by a filter cap that can be locked and unlocked for easy removal and replacement of the filter assembly, allowing for periodic cleaning and reuse by rotating the cap in specific directions, and incorporating features like O-rings and spiral vanes for enhanced sealing and contaminant capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If existing fuel system filters are used, then contaminant capture is maintained, but filter life is reduced and maintenance costs increase due to inability to efficiently remove and dispose of contaminants
Solution Approach 1:
The filter assembly is divided into separable components: a filter body, a removable filter element, and a filter cap with locking mechanism. This segmentation allows the filter element to be independently removed and cleaned without replacing the entire filter assembly, thereby extending filter life while simplifying maintenance operations.
Solution Approach 2:
The filter element is designed to be removable and reusable rather than disposable. The element can be extracted from the filter body, cleaned of accumulated contaminants, and reinstalled, transforming the traditional discard-and-replace model into a recover-and-reuse model that extends service life and reduces waste.
2Adaptability or versatility
If a removable filter assembly design is implemented, then filter reuse is enabled, but device complexity increases due to additional locking and sealing components
Solution Approach 1:
The locking and sealing functions are merged into an integrated filter cap assembly that rotates to lock onto the filter body. The O-ring seal is incorporated into the cap structure, combining multiple functions (sealing, locking, and closure) into a single component that reduces overall system complexity despite enabling reuse.
Solution Approach 2:
The filter cap incorporates a rotational locking mechanism that transitions from an unlocked to a locked state, providing dynamic security. This dynamic feature allows the filter element to be easily removed when needed while ensuring secure containment during operation, balancing accessibility with structural integrity.
3Reliability
If frequent filter replacement is required, then contaminant capture effectiveness is maintained, but loss of time and productivity increase due to frequent maintenance interruptions
Solution Approach 1:
The filter element is designed for easy self-service maintenance where the user can independently remove, clean, and reinstall the filter element without requiring specialized tools or services. This reduces maintenance time and allows quick restoration of contaminant capture effectiveness between uses.
Solution Approach 2:
The filter system is designed for periodic cleaning rather than continuous operation until failure. The filter element can be removed and cleaned at regular intervals, maintaining contaminant capture effectiveness over extended periods and reducing the frequency of complete replacements compared to traditional filters.

AI summary
A number of variations may include a product comprising a dump-able filter comprising: a filter body; a filter assembly, wherein the filter assembly is seated in the filter body; and a filter cap, wherein the filter cap attaches to the filter body and encloses at least a portion of the filter assembly.
