Vacuum hose-pipe adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adapters fail to efficiently and effectively couple with various pipe and hose diameters associated with air conditioning units, leading to negative pressure losses and safety issues during debris removal from condensation pipes.
Innovation Solution
A vacuum hose-pipe adapter with a unitary adapter body bifurcated into a pipe and hose portion, featuring a frustro-pyramidal shape and concentrically configured sidewalls to accommodate different diameters, allowing for secure and flexible coupling without plastic deformation, using a polymeric elastomer material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tight seal between the pipe and hose is achieved, then negative pressure maintenance is improved, but device complexity increases
Solution Approach 1:
The patent merges the pipe coupling section and hose coupling section into a single unitary adapter body made of polymeric elastomer. This integration eliminates the need for separate coupling components while maintaining effective sealing between the pipe and hose, thus improving negative pressure maintenance without proportionally increasing device complexity
Solution Approach 2:
The adapter body is designed with universal coupling capabilities to accommodate various pipe and hose diameters through its bifurcated structure with tapered sections. This multi-functionality allows a single adapter design to effectively seal across multiple size configurations, improving reliability while avoiding the complexity of multiple specialized adapters
2Adaptability or versatility
If a single adapter design is used for various pipe and hose diameters, then adaptability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The adapter incorporates localized tapered sections within its bifurcated structure that allow different portions of the adapter to accommodate different diameters. The frustro-pyramidal shape creates gradual transitions in cross-sectional area, enabling the same component to adapt to various pipe and hose sizes through geometric progression rather than requiring precision manufacturing across all dimensions
Solution Approach 2:
The adapter utilizes changes in geometric parameters along its length, specifically the frustro-pyramidal tapering, to accommodate varying diameters. This parameter progression allows the adapter to adapt to different sizes through its shape rather than requiring precise dimensional control at every cross-section, thus improving adaptability while managing manufacturing precision requirements

AI summary
A vacuum hose-pipe adapter that includes a sidewall bifurcated into two portions, wherein the first portion includes a first distal terminal end defining a distal pipe opening a first portion length separating a first proximal end and the first distal terminal end, and a sidewall inner surface of a frustro-pyramidal shape and enclosed configuration tapering in diameter from the distal pipe opening along the first portion length and the second portion with a second distal terminal end opposing the first distal terminal end and defining a distal hose opening, with a recessed bottom wall, with a sidewall inner surface enclosing and defining a first a first hose diameter, and with a second hose sidewall projecting from the recessed bottom wall, toward the distal hose opening, and enclosing and defining a second hose diameter less than the first hose diameter, thereby allowing fluid to flow therein and between the openings.
