Extendable Air Purifier Housing for Upper-Air Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifiers have limited usability due to their fixed position, which restricts the area that can be purified, especially in providing clean air above the device, as they often lack the ability to blow air upward or downward effectively.
Innovation Solution
The air purifier design features a modular structure with a first and second case that can be adjusted in length, allowing for different operational modes by changing the alignment of suction and discharge ports, enabling more efficient airflow and coverage of a larger area, including above the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the air purifier is positioned at a fixed location with standard discharge outlet configuration, then the device structure remains simple and stable, but the purified air cannot effectively reach upper regions and the coverage area is limited
Solution Approach 1:
The air purifier incorporates a movable main body that can be lifted vertically along guide rails. The lifting mechanism allows the discharge outlets to change their vertical position dynamically, enabling purified air to reach different height zones including upper regions that were previously inaccessible. This dynamic positioning resolves the contradiction by expanding coverage area without fundamentally redesigning the device structure.
Solution Approach 2:
The invention adds vertical movement capability to the traditional horizontal air discharge configuration. By introducing the vertical dimension through the lifting mechanism, the discharge outlets can operate at multiple height levels, effectively expanding the three-dimensional coverage area and solving the limitation of fixed-position air purifiers.
2Ease of operation
If the suction inlet and discharge outlet are positioned on lateral surfaces only, then the device structure remains simple, but air cannot be blown upward or downward effectively limiting purified air supply to regions above the device
Solution Approach 1:
The lifting mechanism enables the discharge outlets to serve multiple functions: discharging air horizontally at lower positions and discharging air upward at elevated positions. This multi-functional capability allows a single discharge outlet configuration to address various air distribution needs without requiring separate specialized outlets for different directions.
Solution Approach 2:
The movable main body allows the discharge outlets to dynamically adjust their orientation relative to the room space. By changing the vertical position of the main body, the same lateral discharge outlets can effectively deliver purified air to different spatial zones including upper regions, enhancing operational flexibility without adding directional discharge mechanisms.
3Area of stationary object
If the main body is moved upward to purify upper air regions, then coverage area is improved, but the operation is restricted to upper and lower portions only
Solution Approach 1:
The lifting mechanism introduces vertical dimensionality to the air purifier's operation, allowing the main body to move between elevated and lowered positions. This enables the device to address both upper and lower air regions comprehensively, transforming a two-dimensional horizontal coverage limitation into a three-dimensional spatial coverage capability.
Solution Approach 2:
The same lifting mechanism that enables upper region purification also facilitates lower region purification by allowing the main body to be positioned at different vertical levels. This multi-functional capability resolves the operational restriction by enabling the device to effectively service the entire vertical space within the room.

AI summary
An air purifier includes a filter, a fan to suction air through the filter, a first case configured to cover the filter and the fan, and a second case overlapping with the first case. The first and second cases may be moveable in a vertical direction such that the second case may be raised to lengthen the air purifier and the first case may be raised to expose the filter for replacement. The second case may be provided outside of the first case and have a side discharge grill and a top discharge grill, which may each be selectively opened and closed.
