Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrostatic powder coating booths are bulky and costly due to the need for significant distance between automatic and manual spraying stations to prevent powder contamination, making them difficult to install in small spaces and inefficient in operator protection.
Innovation Solution
A compact electrostatic powder coating booth design featuring vertically movable partitions that pivot between working and protection positions, integrated with the booth's structure to direct powder flow internally and facilitate easy cleaning, reducing the booth's size while maintaining effective powder containment and operator safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If significant distance is provided between automatic sprayers and manual station, then operator protection from powder pollution is improved, but booth bulk increases making it costly and difficult to install in small premises
Solution Approach 1:
The booth interior is segmented into distinct zones using vertical partitions that create separate working areas for automatic and manual spraying operations. These partitions divide the space without requiring large distances, allowing effective powder containment while maintaining a compact overall booth volume.
Solution Approach 2:
Instead of using horizontal distance to separate spraying zones, the invention uses vertical partitions extending from floor to ceiling to create spatial separation. This dimensional approach to zone separation eliminates the need for large horizontal clearances while maintaining effective powder flow management.
2Volume of stationary object
If vertical partition is positioned close to cabin wall in working position, then booth compactness is improved, but partition cleaning becomes difficult
Solution Approach 1:
The vertical partition is designed to be movable between a working position where it extends close to the cabin wall for compactness, and a cleaning position where it can be accessed from outside the booth. This dynamic repositioning capability allows the partition to serve dual purposes: maintaining compact operational space while enabling easy maintenance access.
Solution Approach 2:
The partition cleaning system is designed to be accessible from outside the booth, allowing cleaning operations to be performed without entering the contaminated interior space. This self-service approach enables maintenance personnel to clean the partition externally, simplifying the cleaning process while maintaining booth compactness during operation.
3Object-affected harmful factors
If partition forms angle between 70° and 110° with cabin wall, then powder flow containment is improved, but structural complexity increases
Solution Approach 1:
The partition is designed with a specific angular range (70° to 110° relative to the cabin wall) that optimizes powder flow containment. This parameter optimization allows the partition to effectively redirect powder flows while maintaining a relatively simple structural design, avoiding the need for complex mechanical adjustment mechanisms.

AI summary
This electrostatic powdering cabin (1) comprises at least one first station (3) for powdering, and at least one second station (5, 7) for manual powdering, which are separate from one another. The manual station (5, 7) is delimited by at least one vertical partition (55, 75) which is arranged inside the cabin, near an opening (51, 71) formed in a wall (13) of the cabin and movable between at least one working position for protection of an operator standing in the manual station, in which position the partition extends into the inside of the cabin and forms an angle of between 70° and 110° approximately with said wall (13), and at least one cleaning position of the partition.
