Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ceiling-mounted air filter housings for cleanrooms require manual and labor-intensive filter replacements, which can be risky and time-consuming, especially in large facilities, and may damage new filters during installation.
Innovation Solution
The air filter housing incorporates resilient members below the sealing surface to temporarily retain and guide filters during installation and removal, using clamping devices with a cam mechanism for secure sealing, reducing manual handling and risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual filter replacement is performed in traditional filter housings, then filter exchange can be completed, but the process is labor-intensive, time-consuming, and carries risk of filter damage
Solution Approach 1:
A resilient retention member is introduced as an intermediary element between the filter frame and the housing. This member temporarily holds the filter in place during insertion and removal, facilitating easier handling and reducing manual effort required for filter replacement operations
Solution Approach 2:
The resilient retention member is pre-positioned within the housing to automatically engage with the filter frame upon insertion. This preliminary positioning action prepares the filter for secure retention before the sealing connection is fully established, streamlining the replacement process
2Ease of operation
If manual filter handling is performed in awkward positions, then filter replacement can be completed, but the risk of filter damage increases
Solution Approach 1:
The resilient retention member serves as a protective intermediary that supports the filter during the critical insertion phase. By providing automatic mechanical retention, it eliminates the need for awkward manual positioning operations that could compromise filter integrity
Solution Approach 2:
The resilient nature of the retention member provides inherent cushioning and shock absorption during filter insertion. This beforehand cushioning protects the filter from impact damage that could occur during manual handling and installation
3Reliability
If filters are secured using traditional sealing connections, then leak-proof sealing is achieved, but substantial manual work in awkward positions is required
Solution Approach 1:
The resilient retention member acts as an intermediary that maintains filter positioning and sealing pressure. This member simplifies the securing operation by providing continuous retention force, reducing the complexity of manual sealing operations while maintaining leak-proof integrity
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
Facilitates faster and safer filter replacements by providing controlled clamping and retention, reducing downtime and improving working conditions for personnel while minimizing filter damage.
Implementation Method 1
the resilient member will be deformed by the filter frame as the filter passes the resilient member, and resume its original shape once the filter has passed
