Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers face challenges in efficiently replacing filters due to unstable airtightness and inconvenient filter management, as users must manually handle filter units and apply lateral pressure, leading to potential hygiene issues and ineffective sealing.
Innovation Solution
A filter support structure with a first body having a protruding part and a second body with an inclined groove allows the filter member to be easily inserted and sealed, enhancing stability and convenience by dispersing load and ensuring proper alignment during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a filter push member applies lateral pressure to expose the filter member, then the filter member can be drawn out, but the filter member becomes unstable and inclined, compromising airtightness
Solution Approach 1:
The patent introduces a guide member as an intermediary component between the filter member and the housing. This guide member includes a guide groove that receives a guide protrusion from the filter member, providing guidance and stability during the filter replacement process. The intermediary guide member prevents direct lateral pressure application that causes instability, while ensuring proper alignment and vertical movement for maintaining airtightness.
2Device complexity
If the entire filter unit is mounted in the filter accommodation part, then filter replacement is simplified, but users must manually grip the filter unit with both hands, creating hygiene issues
Solution Approach 1:
The patent segments the filter unit into separable components: the filter member itself and the first body (support structure). The filter member can be independently removed from the first body through the guide member mechanism, allowing users to handle only the necessary filter component rather than the entire integrated unit. This segmentation enables single-handed operation while maintaining structural simplicity.
3Ease of operation
If lateral pressure is applied to the filter member for exposure, then the filter member can be accessed, but the airtight state cannot be effectively maintained
Solution Approach 1:
Instead of applying lateral pressure to expose the filter member (conventional approach), the patent inverts the approach by using vertical pressure through the guide member. The guide protrusion moves vertically along the guide groove, allowing the filter member to be exposed through upward movement rather than lateral pushing. This inversion maintains the filter member's stable orientation and ensures the sealing surface remains properly aligned with the latching part, preserving airtightness.

AI summary
The present disclosure relates to an air purifier and, more particularly, to an air purifier capable of introducing a filter support structure including a first body supporting a filter member and having a protruding part on a lower surface thereof, and a second body disposed at a lower portion of the first body and having a groove part having an inclined surface in contact with the protruding part formed at one side thereof, thereby allowing the filter member drawn out of the housing to be inserted into an inner space of the housing and simultaneously moving the filter member upward to form a sealing against a latching part, thereby enhancing convenience of filter management and improving air tightness of the filter member.
