Reversible Vacuum Nozzle Adapter for Dust Sampling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for assessing dust mite and other household allergen exposure are inflexible due to limited compatibility with various vacuum hose sizes, restricting direct consumer access and requiring costly professional services for dust sampling.
Innovation Solution
A system comprising a hollow nozzle with an angled tip, a filter trap, and a reversible adapter with multiple rings to accommodate different hose diameters, allowing secure attachment to a variety of vacuum hoses for efficient dust collection and sampling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional nozzles are used with limited hose connection sizes, then the device structure is simple, but the adaptability to different vacuum hoses is poor
Solution Approach 1:
The adapter is divided into multiple sections with different sized rings (first outer ring, first inner ring, second outer ring, second inner ring) that can be independently selected based on hose diameter, allowing the same adapter body to accommodate various hose sizes through segmented connection options
Solution Approach 2:
The adapter serves multiple functions: it connects to different hose diameters through various rings, attaches to the nozzle, and provides a secure friction fit connection system. This multi-functional design allows a single device to replace multiple specialized adapters
2Measurement precision
If professional dust sampling services are used to ensure accurate allergen assessment, then the measurement precision is high, but the cost and accessibility are poor
Solution Approach 1:
The system enables consumers to perform dust sampling and allergen assessment themselves using the adapter with vacuum hoses, eliminating the need to hire professional services. The adapter makes the sampling process accessible to ordinary consumers while maintaining assessment accuracy
3Adaptability or versatility
If adapter tubes and extension kits are used to accommodate different hose diameters, then the adaptability is improved, but the device complexity and size increase
Solution Approach 1:
Multiple adapter functions are merged into a single integrated adapter body that contains all four rings (first outer ring, first inner ring, second outer ring, second inner ring) with different diameters. This consolidation allows the same device to accommodate various hose sizes without requiring multiple separate adapter components
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and secure attachment to a wide range of vacuum hoses, facilitating efficient dust collection and sampling, making it accessible for consumers to assess allergen exposure without the need for professional services, while allowing for compact packaging and mailing.
Implementation Method 1
air suction device such as a vacuum cleaner... to draw air from the test site into the nozzle
Implementation Method 2
a filter trap which may be inserted into and retained within the hollow cylinder but is also removable therefrom
