Semi-Rigid Filter Frame Mechanism for Simplified Bag Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter assembly replacement processes are complex and time-consuming due to the need to remove external components for securing filter bags, which complicates the replacement of filter bags within a housing.
Innovation Solution
A semi-rigid frame mechanism that is flexibly movable and can be quickly snapped into and out of engagement with the housing to secure a pocket filter, allowing for self-sealing and self-supporting functionality without additional components, enabling easier filter bag replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external components (nuts, bolts, lock bars, clips, tie rods, springs, and clamps) are used to secure the filter bag within the housing, then the filter bag can be reliably retained, but the replacement process becomes more complex and time-consuming due to the need to remove these external components
Solution Approach 1:
The frame integrates both support and securing functions into a single component structure. The frame includes a first portion that supports the filter bag and a second portion that secures the filter bag to the housing, eliminating the need for separate external components like nuts, bolts, and clamps.
Solution Approach 2:
The frame is designed to be flexibly movable between a first position (unconstrained) and a second position (constrained). This dynamic capability allows the frame to be easily inserted and removed from the housing by flexing it into the constrained position, simplifying the replacement process while maintaining secure retention during operation.
2Reliability
If conventional external components are used to secure the filter bag, then the filter bag can be held in place, but the overall replacement process becomes slower due to additional steps required to remove and install these components
Solution Approach 1:
The frame combines support and securing functions into one integrated component, eliminating the multiple separate external components that would otherwise need to be individually installed and removed during replacement.
Solution Approach 2:
The flexibly movable frame can be quickly transitioned between constrained and unconstrained states, enabling rapid installation and removal without the time-consuming process of assembling and disassembling multiple fastening components.
3Stability of the object's composition
If a rigid frame is used to support the filter element, then structural stability is improved, but the ability to quickly engage and disengage from the housing is reduced
Solution Approach 1:
The frame is designed with flexible movability between constrained and unconstrained positions, allowing it to be easily inserted and removed from the housing while maintaining structural stability during operation when in the constrained position.
Solution Approach 2:
The frame's rigidity parameter is dynamically adjusted through its ability to transition between constrained (rigid for stability) and unconstrained (flexible for easy movement) states, resolving the contradiction between structural stability and ease of operation.

Function Achieved in This Case
The semi-rigid frame mechanism simplifies the filter bag replacement process by allowing for quicker engagement and disengagement, reducing complexity and eliminating the need for external components, thus enhancing the efficiency of filter assembly maintenance.
Implementation Method 1
a semi-rigid member having opposite ends that are each secured to the mounting portion of the mating frame and a flexible portion between the opposite ends that is flexibly moveable to constrain the semi-rigid member at the opposite ends
Implementation Method 2
When in the constrained position, the semi-rigid planar member compresses the first end of the filter media against the housing for holding the filter media in place

AI summary
A securing mechanism and a method for securing a filter element within a housing may be implemented in a pocket-type or cartridge-type filter assembly. The securing mechanism includes a mating frame having a retaining portion extending into the filter element within the housing for retaining the filter element within the housing, and a mounting portion mounted to the housing. The securing mechanism includes a semi-rigid member having opposite ends that are each secured to the mounting portion of the mating frame and a flexible portion between the opposite ends that is flexibly moveable to constrain the semi-rigid member at the opposite ends. The semi-rigid member is pressed against the mating frame to hold the filter element in place when the semi-rigid member is constrained.
