Vacuum conduit attachment tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vacuum cleaner attachment tools are not adaptable for use with vacuum hoses or conduits of varying sizes, requiring separate adapters or tools and often lack locking mechanisms to secure the attachment, leading to potential detachment during use.
Innovation Solution
A vacuum attachment tool with a hollow body and a conduit connector featuring inner and outer collars of different diameters, along with teeth and ribs for locking mechanisms, allowing for secure engagement with hoses or conduits of different sizes and preventing movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-size attachment tool is used, then the device complexity is reduced, but the adaptability to different hose sizes deteriorates
Solution Approach 1:
The attachment tool incorporates a conduit connector with nested collars of different diameters, allowing a single tool to accommodate multiple hose sizes (e.g., 1-1/4 inch and 1-1/2 inch) without requiring separate adapters or tools
2Device complexity
If no locking mechanism is included, then the device complexity is reduced, but the reliability of connection deteriorates
Solution Approach 1:
The conduit connector includes locking mechanisms that automatically engage with the hose during the normal connection process, eliminating the need for separate manual locking operations while ensuring secure attachment

AI summary
A vacuum attachment tool includes a hollow body extending from a first end to a second end and defining a flow path, and a conduit connector disposed at the second end of the hollow body. The conduit connector includes an inner collar having an inner diameter sized to receive a first vacuum conduit having a first diameter, and an outer collar having an inner diameter sized to receive a second vacuum conduit having a second diameter greater than the first diameter. The outer collar is formed separately from the inner collar and is coupled to the inner collar.
