Ceiling Filter Housing With Resilient Retention for Fast Replacement
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 labor and risk of damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual filter replacement is used in traditional filter housings, then filter installation is simple, but the process is labor-intensive and time-consuming
Solution Approach 1:
The filter housing incorporates a dynamic clamping mechanism that automatically adjusts during filter installation. The resilient members deform to accommodate the filter frame and then resume their original shape to secure the filter, transforming a static housing into an adaptive system that reduces manual labor and installation time
Solution Approach 2:
The resilient members provide self-retaining functionality, automatically securing the filter in position without requiring additional fastening operations. The system serves itself by using the insertion force to deform the resilient members, which then naturally return to their original shape to clamp the filter, eliminating the need for separate securing steps
2Ease of operation
If manual filter installation is performed in awkward positions, then filter replacement can be done, but the risk of damage to new filters increases
Solution Approach 1:
The resilient members are pre-positioned within the housing to guide the filter frame during insertion. This preliminary positioning ensures that the filter is properly oriented and supported before the clamping action occurs, preventing misalignment and potential damage during installation
Solution Approach 2:
The resilient members act as intermediaries between the filter frame and the housing structure. They provide a compliant interface that absorbs insertion forces and distributes clamping pressure evenly, protecting the filter from direct contact with rigid housing surfaces that could cause damage
3Reliability
If a leak-proof sealing connection is achieved using bolts or nuts, then filtration reliability is improved, but the complexity of filter replacement increases
Solution Approach 1:
The invention extracts the fastening function from the traditional bolt-nut assembly and transfers it to the resilient members. By removing the complex fastening hardware and replacing it with elastic retention, the system maintains sealing integrity through the resilient clamping action while dramatically simplifying the overall structure and installation process
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 controlling the clamping process, reducing downtime and minimizing risks to the new filters, while ensuring a leak-proof seal and easy access for different filter sizes.
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
