Air Purifier Coupling Mechanism for Single-Action Filter Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifier devices face difficulties in filter replacement, making the process cumbersome and risking improper filter positioning, which can impair the device's function.
Innovation Solution
The air purifier device is structurally divided into a fan unit and a filter unit with a coupling mechanism featuring two release means on opposite outer sides of the fan unit, allowing for easy removal and replacement of the filter unit by lifting the fan unit off, facilitating correct positioning and reducing the risk of impaired function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional grille structure is used to secure the filter to the housing, then the filter can be replaced, but the replacement process is cumbersome and may result in improper positioning
Solution Approach 1:
The device is divided into separate functional units: a filter unit and a fan unit, which can be independently handled. The filter unit can be removed and replaced without disturbing the fan unit, making the replacement process simpler and more reliable.
Solution Approach 2:
The coupling mechanism between the fan unit and filter unit uses dynamic elements (springs, movable coupling elements) that automatically engage and disengage. This allows for easy separation and reconnection while ensuring proper positioning through the mechanical design of the coupling interface.
2Stability of the object's composition
If the fan unit and filter unit are tightly integrated, then structural stability is improved, but filter replacement becomes difficult
Solution Approach 1:
The air purifier is segmented into a stationary housing containing the fan unit and a removable filter unit. This segmentation allows the filter unit to be easily detached for replacement while the fan unit remains securely in place, resolving the contradiction between structural stability and ease of filter replacement.
Solution Approach 2:
A coupling mechanism acts as an intermediary between the fan unit and filter unit. This coupling mechanism provides secure connection during operation (maintaining structural stability) while allowing for easy separation when needed (enabling filter replacement). The coupling elements include springs and movable components that facilitate controlled engagement and disengagement.

AI summary
An air purifier device (1) is provided comprising a fan unit (2) comprising a fan (4) arranged to produce an air flow through the air purifier device, and a filter unit (3) comprising a filter (9) arranged to filter the air flow produced by the fan. The filter unit is adapted to stand on a support surface when the air purifier device is positioned for use. The air purifier device further comprises a coupling mechanism (10) arranged to secure the fan unit on top of the filter unit. The coupling mechanism comprises two release means (11) arranged on opposite outer sides of the fan unit, and the fan unit is releasable from the filter unit by actuating the two release means. The filter unit may be removed from the fan unit by a single action (or movement) by the user, whereby filter replacement of the air purifier device is facilitated.
