Paint Mist Removing Apparatus Filter Replacement Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional paint mist removing apparatuses face difficulties in facilitating the filter replacement process, as paint tends to scatter during the replacement of used filters, making the process cumbersome and troublesome.
Innovation Solution
The apparatus features a duct with a frame-like projection that abuts the entire circumference of the filter case exit, combined with a side-surface opening mechanism that allows for easy insertion and removal of filter elements, preventing paint scatter and simplifying the replacement process by ensuring all air passes through the filter part, reducing interference and facilitating smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional filter is used in a paint mist removing apparatus, then the filter can remove paint mist from air, but the filter replacement process becomes troublesome and paint scatters during replacement
Solution Approach 1:
The filter assembly is segmented into a filter case and a filter element that can be independently removed. The frame-like projection allows the filter element to be extracted from the filter case without removing the entire filter assembly, enabling easy replacement while containing the used filter element to prevent paint scatter.
Solution Approach 2:
The frame-like projection acts as an intermediary structure that facilitates filter element removal. It provides a gripping surface and extraction path for the filter element, making the replacement process easier while maintaining containment to prevent paint scatter during the operation.
2Ease of operation
If the filter element is easily removable for replacement, then maintenance becomes simpler, but paint mist may leak or scatter during the replacement process
Solution Approach 1:
The segmentation of the filter element from the filter case allows easy removal while the frame-like projection ensures that the separation occurs in a controlled manner that maintains paint mist containment throughout the process.
Solution Approach 2:
The frame-like projection is pre-configured to guide the filter element removal path, ensuring that the filter element can be extracted easily while maintaining proper alignment and containment to prevent paint mist leakage during the replacement operation.
3Manufacturing precision
If all air is forced through the filter part via the case exit, then filtration efficiency is improved, but the structure becomes more complex
Solution Approach 1:
The frame-like projection merges the structural support function with the air flow guidance function. It simultaneously provides structural integrity to the duct and directs all air flow through the filter part, achieving high filtration efficiency without adding separate complex components.
Solution Approach 2:
The frame-like projection serves multiple functions: it provides structural support for the filter case, guides air flow through the filter element, and facilitates easy removal of the filter element. This multi-functionality achieves high filtration efficiency while minimizing structural complexity.

AI summary
A paint mist removing apparatus includes: a duct through which air containing paint mist passes; an element fit part provided at the duct, the element fit part being fitted with a filter element including a filter part configured to remove the paint mist and a filter case housing the filter part, the filter case having a case exit from which all air taken in from a case entrance of the filter case is caused to exit through the filter part; an frame-like projection projecting from an inner surface of the duct and abutting on an entire circumference of an opening edge of the case exit of the filter case; and a duct side-surface opening being open at a side surface of the duct and normally closed by a door member, the duct side-surface opening being open when the filter element is set in and out from the element fit part.
