Air Purifier with Vertically Movable Cases for Multi-Zone Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifiers have limited usability due to restricted air discharge, primarily focusing on upper and lower portions, which hinders efficient purification of indoor spaces and user satisfaction, especially for users who prefer indirect airflow.
Innovation Solution
An air purifier design featuring a movable first and second case configuration, with a cylindrical filter and linear motion guides, allowing adjustable height and simultaneous use of both cases for enhanced airflow and user preference in air distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the air purifier uses a fixed position with limited discharge outlets, then the device structure is simple, but the area capable of being purified is limited
Solution Approach 1:
The patent implements a movable main body that can lift up and down vertically. The discharge outlets are positioned on the main body, which moves to different heights, enabling the air purifier to discharge cleaned air to various areas (upper, lower, and lateral regions) and expand the effective purification area without increasing structural complexity
Solution Approach 2:
The patent adds vertical movement dimension to the traditional horizontal discharge configuration. By moving the main body vertically, the discharge outlets can reach different spatial zones, transforming a 2D discharge pattern into a 3D coverage area, thereby expanding purification coverage without adding more discharge outlets
2Adaptability or versatility
If the suction inlet and discharge outlet are provided on lateral surfaces, then the device structure is simple, but air cannot be blown upward or downward effectively
Solution Approach 1:
The main body with discharge outlets moves vertically to change the spatial position of the outlets. This dynamic positioning allows the same lateral discharge structure to serve multiple functions by discharging air to different directions (upward, downward, lateral) depending on the main body's vertical position, without requiring multiple fixed discharge structures
Solution Approach 2:
The movable main body structure serves multiple purposes: it acts as both the housing and the discharge mechanism. The same structural element (main body) performs both structural support and active air distribution to multiple zones, eliminating the need for separate complex discharge structures for different directions
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables efficient purification of entire indoor spaces by adjusting the air discharge height and mode, improving user satisfaction by accommodating various airflow preferences and increasing the air cleaning capacity per unit time.
Implementation Method 1
a fan to suction outside air by applying negative pressure to a filter or filter member
Implementation Method 2
a linear motion (LM) guide that forms a skeleton of an air purifier and permits relative movement between at least two members so that the case may be smoothly moved or adjusted

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.
