Paint Booth Filter Module Rail Alignment for Airtight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paint booth filter units face challenges in maintaining a correct sealing state between the air inlet and outlet surfaces, especially when the inlet and outlet are positioned on different surfaces, leading to difficulties in ensuring flatness and accurate alignment, which affects air flow rate and sealing performance.
Innovation Solution
A paint apparatus with a filter module that includes a rail and wheel system to guide the filter module into a precise attached position, ensuring airtight connections between the filter inlet and outlet, and utilizing a front chamber to adjust height differences and distribute air flow effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the inlet and outlet are arranged in different surfaces to increase air flow rate, then the air flow rate is improved, but it becomes difficult to ensure sealing performance at both joining surfaces
Solution Approach 1:
A guide rail is introduced as an intermediary component between the filter unit and the receiving portion. The guide rail provides a fixed reference path that guides the filter unit into the correct position, mediating the connection between the movable filter unit and the stationary receiving portion to ensure proper alignment and sealing at both joining surfaces
Solution Approach 2:
The filter unit is designed with self-aligning capabilities through its interaction with the guide rail. As the filter unit is moved along the guide rail, it automatically positions itself correctly relative to the receiving portion, enabling self-service alignment without requiring external positioning equipment or complex adjustment mechanisms
2Ease of operation
If the filter unit moves on the floor surface, then the filter unit is easily installable and maintainable, but it becomes difficult to ensure flatness of the floor and accurate matching of joining surfaces
Solution Approach 1:
The guide rail serves as a mediator between the movable filter unit and the floor surface. It provides a stable, precise reference path that is independent of floor flatness, allowing the filter unit to be easily moved and positioned while ensuring accurate joining surface alignment through the rail's fixed geometry
Solution Approach 2:
The positioning system is segmented into two independent functions: the guide rail handles precise positioning and alignment, while the floor surface only needs to provide basic support for movement. This segmentation allows the filter unit to be easily movable on the floor while maintaining high positioning precision through the guide rail mechanism

AI summary
The paint apparatus includes a paint booth having an upper chamber in which a painting operation is performed and a lower chamber placed below the upper chamber; a receiving portion 2 that receives air discharged from the paint booth; a filter module 3 attachable to and detachable from the receiving portion 2 and including filter portions 31 and 32 that trap paint mist from air that passed through the receiving portion 2, a filter inlet portion 33 that receives an inflow of air from the receiving portion 2, and a filter outlet portion 34 that discharges air from which the paint mist was trapped by the filter portions 31 and 32; and rails 6 that guide the filter module 3 to an attached position at which the filter module 3 is attached to the receiving portion 2.
