Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing liquid fuel containers lack convenient and effective filtration systems that can quickly filter out small particulates before pouring into a fuel tank, and existing filters are not easily replaceable or adjustable to different screen sizes.

Innovation Solution

A liquid container system with a removable spout cap and inner/outer bosses for easy installation of filters with adjustable mesh screens, forming a fluid flow path through the container, and a hose assembly for seamless integration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a filter is integrated into the container, then liquid fuel can be filtered before pouring, but the filter becomes clogged with particulates and cannot be replaced or adjusted

Engineering Contradiction:

Improvefiltration effectivenessVSAvoidfilter replaceability

Core Design Contradiction:

ReliabilityVSEase of repair

Solution Approach 1:

The filter is designed as a separate, detachable component that can be independently removed and replaced from the spout cap assembly. This segmentation allows the filter to be maintained separately from the main container structure, enabling easy replacement when clogged without affecting other components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The filter system transitions from a static, fixed integration to a dynamic, interchangeable configuration. Multiple filters with different screen sizes can be swapped based on operational needs, allowing the system to adapt to different filtration requirements and maintain effectiveness over time.

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If a filter with large screen size is used, then the filter structure is simple, but it does not filter out critical smaller particulates

Engineering Contradiction:

Improvefilter structure simplicityVSAvoidparticulate filtration effectiveness

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The system allows changing the screen size parameter of the filter by swapping filters with different mesh configurations. This enables adjustment of filtration precision from coarse to fine depending on the specific application requirements, resolving the trade-off between simplicity and effectiveness.

Inventive Principle:

Principle #35Parameter changes

3Productivity

If no filter is used, then the system is simple and quick to use, but particulates foul the fuel system and engine

Engineering Contradiction:

Improvefueling speedVSAvoidparticulate contamination

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The filtration function is extracted as a separate, optional component rather than being integrated into the essential pouring mechanism. This allows the system to maintain simplicity and speed when filtration is not needed, while providing protective filtration capability when required, without compromising the core fueling operation.

Inventive Principle:

Principle #2Taking out (Extraction)

4Device complexity

If a non-replaceable filter is integrated into the spout cap, then the structure is compact, but the screen size cannot be adjusted for different filtration needs

Engineering Contradiction:

Improvespout cap structureVSAvoidfilter screen size adjustability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The spout cap assembly is designed with a universal interface that can accommodate multiple filter types with different screen sizes. This multi-functional design allows the same basic structure to support various filtration configurations, providing adaptability without increasing fundamental structural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A container may include a generally hollow body configured for holding a liquid and including a spout. A spout cap may be configured for removable engagement with the spout. The spout cap may include an inner boss and an outer boss in fluid communication with the inner boss. The inner boss may include an annular skirt disposed within an interior space of the spout cap. The outer boss may be configured to receive a connector of a hose assembly. A filter may have a connecting portion configured for removable insertion into the inner boss. The filter and the spout cap may form a fluid flow path from the body through the spout. Related filters, hose assemblies, and kits are also described.
