Filter Unit with Hinged Cover Plate for Clean Room Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter units in clean rooms require cumbersome and time-consuming processes for filter replacement and leak testing, with a high risk of safety accidents and disruptions to the clean environment during cover plate removal and equipment installation.
Innovation Solution
A filter unit design featuring a hinged cover plate and integrated piping systems for fluid communication and aerosol injection, allowing for safe and efficient filter replacement and leak testing without removing the cover plate, and minimizing interference with the filter box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the cover plate is removed for filter replacement, then the filter box is accessible for maintenance, but the process becomes time-consuming and safety risks increase
Solution Approach 1:
The cover plate is designed to be movable rather than fixed, allowing it to be opened and closed as needed. The hinge connection enables dynamic access to the filter box without permanent disassembly, resolving the contradiction between accessibility and time consumption.
Solution Approach 2:
The cover plate is divided into multiple sections (first cover plate and second cover plate) that can be independently opened. This segmentation allows selective access to different parts of the filter box, maintaining accessibility while reducing the time and effort required for maintenance operations.
2Reliability
If the cover plate is removed for equipment installation, then leak testing can be performed, but the clean room environment is disrupted and safety risks increase
Solution Approach 1:
The piping parts are pre-installed and integrated into the frame structure before the cover plate is attached. This preliminary action allows leak testing equipment to be connected through the openable cover plate without requiring its removal, thereby maintaining the clean room environment while enabling reliability testing.
Solution Approach 2:
The openable cover plate serves as an intermediary mechanism that provides access for installing leak testing equipment and piping connections without requiring complete disassembly. This mediator maintains the seal and cleanliness of the clean room environment while allowing necessary testing operations.
3Reliability
If piping equipment is installed on the filter unit, then leak testing is enabled, but the device complexity increases
Solution Approach 1:
The piping parts are merged with the frame structure, forming an integrated assembly. The first piping part connects to the housing and the second piping part connects to the filter box, creating a unified system that reduces overall complexity while maintaining leak testing functionality.
Solution Approach 2:
The frame structure serves multiple functions: it provides structural support, holds the filter box, and integrates the piping system for leak testing. This multi-functionality reduces the need for separate components, thereby reducing device complexity while maintaining testing capabilities.
