Recirculating Paint Shroud for Overspray Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional painting techniques are labor-intensive and result in excessive waste and the release of hazardous chemicals due to inefficient paint consumption and overspray.
Innovation Solution
A shroud device with a suction and blowing portion that recirculates overspray droplets back into the paint flow, utilizing a combination of suction and blowing forces to direct airflow and capture overspray, reducing waste and emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If traditional painting techniques are used, then labor intensity and waste are high, but the painting process can be completed
Solution Approach 1:
The patent captures harmful overspray that would otherwise be wasted and redirects it back to the painting surface through recirculation channels, converting the harmful waste into beneficial paint application material
Solution Approach 2:
The system recovers overspray droplets that would normally be discarded into the environment, capturing them through suction ports and recirculating them back to the painting surface through blowing ports
2Productivity
If paint spraying is used, then paint application efficiency is improved, but hazardous chemicals are released into the air
Solution Approach 1:
The patent transforms the harmful overspray emissions into a beneficial resource by recirculating them back to the painting surface, eliminating air pollution while maintaining painting efficiency
Solution Approach 2:
The system prevents hazardous chemicals from being discarded into the atmosphere by capturing overspray through suction ports and recovering it for reuse on the painting surface
3Loss of substance
If a shroud device with suction and blowing portions is used to recirculate overspray, then paint waste and emissions are reduced, but device complexity increases
Solution Approach 1:
The patent combines suction and blowing functions into a single integrated shroud device that attaches to the spray gun, merging multiple functions into one compact unit that reduces overall system complexity
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 shroud device effectively recirculates a significant portion of overspray back onto the painting surface, minimizing waste and hazardous emissions, while ensuring efficient paint application.
Implementation Method 1
a suction force introduced within the shroud via the at least one suction hole
Implementation Method 2
a blowing force introduced within the shroud via the at least one blowing slot

AI summary
A shroud device (e.g., a paint sprayer shroud), according to particular embodiments, is configured to capture overspray (e.g., paint or other material that is applied to an unintended location) and/or increase an amount of paint that is delivered to a desired location (e.g., on a wall being painted, etc.). In various embodiments, the shroud device is configured for use in conjunction with a sprayer (e.g., such as any suitable paint spryer or other sprayer). In particular embodiments, the shroud device may comprise a blower portion and a suction portion that work in conjunction to recirculate overspray into a sprayer flow and onto a medium, for example, via a recirculation shroud.
