Rotatable Filter Holder for Cartridge Replacement in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional filter units face difficulties in replacing filter cartridges when installation space is restricted, as the cartridge is hard to detach due to proximity to the ground, requiring the entire holder to be removed from the bracket.
Innovation Solution
A filter holder design that allows the filter cartridge to be rotated relative to the bracket, featuring a body with a locking rib that engages with an engaging groove, facilitated by a trigger component to release the engagement, enabling easy replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter holder is fixed on a bracket and the filter cartridge is connected below it, then the structure is stable and compact, but there is no enough space to move the filter cartridge downward for replacement when the bottom is too close to the ground
Solution Approach 1:
The filter holder is designed to be rotatable relative to the bracket through a trigger component that releases a locking rib from an engaging groove. This dynamic transformation allows the filter holder to change its orientation, moving the filter cartridge away from the ground to provide sufficient space for replacement operations without requiring additional installation area.
Solution Approach 2:
Instead of moving the filter cartridge vertically downward in a straight line, the invention introduces rotational movement around the bracket, utilizing a different dimensional approach. The filter holder can rotate to reposition the cartridge in three-dimensional space, effectively using the vertical dimension created by rotation rather than horizontal displacement.
2Ease of operation
If the filter holder needs to be removed from the bracket to replace the filter cartridge, then the filter cartridge can be replaced, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The invention separates the filter holder from the bracket connection, allowing the holder to rotate independently while remaining attached. This segmentation enables the filter cartridge to be accessed and replaced without removing the entire assembly from the bracket, significantly reducing replacement time and improving operational convenience.
Solution Approach 2:
The trigger component acts as an intermediary mechanism between the operator and the locking rib. By pressing the trigger component, the operator can quickly release the locking rib from the engaging groove, enabling rapid rotation and filter cartridge replacement without complex disassembly procedures.

AI summary
A filter holder has an assembling base, a trigger component, and a body. The assembling base includes a mounting portion and a body holder having a connecting hole, a slit, a blocking end, and an engaging groove. The trigger component is connected to the body holder. The body is rotatably connected to the assembling base and has a cap, a connecting tube inserted into the connecting hole of the body holder, and a locking rib able to be located in the slit and the engaging groove. The trigger component is pressed away from the slit to drive the body holder to release an engagement between the engaging groove of the body holder and the locking rib of the body.
