Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel tank filters are inadequate in removing debris particles from fuel during filling, potentially harming vehicle engines and are not cost-effective or reliable.
Innovation Solution
A fuel tank filter assembly with a microfilter particle sock having a widened shape at the bottom to improve fuel flow, combined with a pressure release locking cap and adapter ring for secure attachment to the fuel tank filler neck, ensuring effective filtration and pressure management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional fuel filter is used in the fuel tank, then fuel filtration is provided, but the filter becomes overridden with debris from dirty fuel and fails to remove particles effectively
Solution Approach 1:
The invention extracts the filtration function from the traditional in-tank filter location and relocates it to a portable filter assembly that attaches to the fuel filler neck. This allows the filter to be positioned outside the fuel tank where it can be easily removed, cleaned, or replaced, preventing debris accumulation from overwhelming the filter system.
Solution Approach 2:
The portable filter assembly is attached to the fuel filler neck before fueling begins, establishing filtration capability in advance. The filter is positioned to intercept debris particles as fuel enters the tank, preventing them from entering the fuel system before they can accumulate and cause problems.
2Object-affected harmful factors
If a portable filter assembly is attached to the fuel filler neck, then debris particles are removed from fuel, but the assembly adds complexity to the fueling process
Solution Approach 1:
The adapter ring is designed with a universal attachment mechanism that fits various fuel filler neck configurations. The lockable connection system serves multiple functions: securing the filter assembly, preventing accidental detachment, and providing a simple interface for attachment and removal, thereby reducing operational complexity despite adding filtration capability.
3Ease of manufacture
If the filter sock has a standard shape, then manufacturing is simple, but fuel flow may be restricted due to debris accumulation
Solution Approach 1:
The filter sock is constructed with varying mesh densities at different locations. The upper portion has a finer mesh for capturing smaller debris particles, while the lower portion has a coarser mesh that maintains open flow paths. This localized variation in filtration quality prevents clogging while maintaining effective particle removal, balancing manufacturing complexity with fuel flow productivity.

AI summary
A fuel tank filter assembly and fuel system designed to be used as fuel is initially added to a vehicle. A removable, and cleanable filter sock is provided comprised of mono filament capable of straining micro particles. A pressure release locking cap is also provided. The filter sock allows fuel to flow at a normal rate while still catching and thereby removing unwanted debris.
