Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling airborne dust during product mixing in containers are inadequate, as simply placing a vacuum hose near the edge of the bucket fails to effectively capture suspended particles, posing risks to workers.
Innovation Solution
A dust control device with a funnel-shaped inlet and a vacuum attachment point that creates a low-pressure zone using a shop vacuum, effectively capturing airborne contaminants by accelerating material and air through a narrowing opening, thereby reducing dust exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a vacuum hose is placed near the edge of the bucket to control dust, then the device complexity is reduced, but the effectiveness of dust capture deteriorates
Solution Approach 1:
The patent introduces a funnel-shaped inlet as an intermediary component between the vacuum source and the mixing container. This intermediary structure creates a controlled airflow path that directs dust particles toward the vacuum attachment point, significantly improving capture effectiveness without requiring complex positioning of the vacuum hose itself
Solution Approach 2:
The patent utilizes pneumatic principles by creating a low-pressure zone through the funnel-shaped inlet that draws dust particles into the vacuum stream. The narrowing opening accelerates air flow and generates suction that actively pulls contaminants toward the collection point, enhancing the vacuum's dust capture capability
2Reliability
If a funnel-shaped inlet with narrowing opening is used to create low-pressure zone, then dust capture effectiveness is improved, but device complexity increases
Solution Approach 1:
The dust control device is segmented into distinct functional components: a funnel-shaped inlet for creating low-pressure zone, a narrowing opening for accelerating airflow, and a vacuum attachment point for dust collection. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity
Solution Approach 2:
The patent employs parameter changes by varying the cross-sectional area of the inlet funnel from wide at the top to narrow at the bottom. This geometric parameter change creates the desired low-pressure zone and accelerates airflow according to Bernoulli's principle, achieving effective dust capture through a relatively simple structural modification
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
The device effectively captures airborne dust and contaminants, providing a safer working environment by ensuring that the mixture is free from suspended particles before the container is removed, thus protecting workers from harmful airborne hazards.
Implementation Method 1
The resulting process can put the person at risk of airborne particles. The inventor was pondering this idea, and started thinking about different ways to control the dust. Workers were trying to set a vacuum hose near the edge of the bucket but this did not effectively control the dust. The inventor drew up his idea and experimented with a prototype and proved his theory that by creating a venturi while isolating the vacuum attachment point

AI summary
This invention (FIG. 1) was conceived out of necessity to control hazardous conditions created while mixing materials like concrete or mortar in containers (1) such as a three gallon or five gallon bucket. The invention (2) is a vacuum attachment which produces a low pressure zone within the bucket when a vacuum is applied to the outlet port (3) of the invention that will keep dust and other airborne material from leaving the interior of the invention through the top of the opening (4). It consists of a funnel shaped opening (4) on the top and a channel around the underside of the funnel leading to the vacuum attachment opening (3), which creates high and low pressure zones, which controls the release of particulate into the atmosphere.
