Suction Grille Filter Holder With Axial Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter holders for suction grilles are difficult to pull out, especially when additional components are present, making it hard to grasp and remove them properly.
Innovation Solution
A filter holder design featuring coupling means with hooks that engage with the suction grille and a release member that includes a release member with a pin and cam mechanism to push the base grille away from the grille, allowing the filter holder to be disconnected without rotating it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filter holder uses hooks that engage with projections on the suction grille, then the filter holder is securely retained and cannot be pulled out easily, but it becomes difficult to remove the filter holder when additional components are present around it
Solution Approach 1:
The invention divides the removal function into two independent parts: the coupling hooks that provide secure retention, and a separate release member that enables easy removal. The release member is a distinct component that can be operated independently from the filter holder body, allowing users to disengage the hooks without manipulating the entire filter holder assembly. This segmentation resolves the contradiction by maintaining secure retention through the hooks while enabling easy removal through the separate release mechanism.
Solution Approach 2:
The release member acts as an intermediary tool between the user and the coupling hooks. Instead of requiring direct manipulation of the filter holder to disengage the hooks, the release member mediates this action by translating user input (pushing motion) into hook disengagement. This intermediary mechanism allows easy removal even when additional components surround the filter holder, as the user only needs to access the release member rather than the entire assembly.
2Reliability
If the filter holder requires rotation to disengage the hooks from projections, then secure retention is maintained, but the operation becomes complex and requires grasping the holder
Solution Approach 1:
The invention inverts the traditional disengagement mechanism. Instead of requiring rotation to release the hooks, the release member translates a linear pushing motion into rotational movement of the hooks relative to the projections. The release member, when pushed along the axis, causes the coupling hooks to rotate outward and disengage from the projections. This inversion simplifies the user operation from complex grasping and rotating to simple pushing, while maintaining connection stability during normal use.
3Stability of the object's composition
If additional components are present around the filter holder, then the holder can be securely positioned, but it prevents proper grasping and removal of the holder
Solution Approach 1:
The invention extracts the removal function from the filter holder body itself and places it in a separate release member. This extraction allows the release mechanism to be positioned in a location that is accessible even when additional components surround the filter holder. The release member can be designed to protrude or be positioned such that it remains accessible for operation, while the filter holder body and its surrounding components maintain their stable positioning function without interfering with release member access.
