Solution Overview

Problem

Conventional couplers fail to effectively couple conduits, such as garden hoses, with large containers, like drums, for fluid transfer, lacking a reliable mechanism for fluidic connection.

Innovation Solution

A conversion fitting with a body having an aperture element, an upper annular member with ANSI hose coupling thread, and a lower annular member with bunghole thread, along with a telescoping tubular member for secure fluidic coupling between conduits and containers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional couplers are used, then simple structure is maintained, but fluidic coupling between conduits and containers cannot be achieved

Engineering Contradiction:

Improvefluidic coupling capabilityVSAvoidcoupler structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The conversion fitting integrates multiple functions into a single device: it provides both a conduit coupling interface (with ANSI hose coupling threads) and a container aperture element interface (with bunghole threads), enabling one component to perform both coupling functions simultaneously

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The conversion fitting acts as an intermediary device that bridges the gap between incompatible coupling systems (conduit couplers and container aperture elements), translating between different threading standards to enable fluidic connection

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If conversion fitting with multiple threading configurations is used, then adaptability is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvethreading configuration compatibilityVSAvoidproduction process

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent combines multiple threading configurations (ANSI hose coupling threads and bunghole threads) into a single integrated conversion fitting body, allowing both interfaces to be manufactured as one unified component rather than separate assemblies

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If secure fluidic coupling is achieved, then connection reliability is improved, but device complexity increases

Engineering Contradiction:

Improveconnection seal integrityVSAvoidfitting component structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The conversion fitting incorporates a flexible gasket element that deforms to create a seal between the rigid threaded interfaces, providing leak-proof fluidic coupling while maintaining structural simplicity

Inventive Principle:

Principle #30Flexible shells and thin films
