Air Purifier Dual Exit Path Design for Even Air Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers often fail to ensure even distribution of purified air, leading to inefficient operation and prolonged time to achieve air purification in a closed space, and their air quality outputs fluctuate significantly with changing conditions.
Innovation Solution
The air purifier features dual exit paths, with one path directing air axially and the other at an angle between 10 to 45 degrees, ensuring separate and efficient air circulation to prevent dead zones and provide consistent air quality feedback through a sensor and algorithmic output.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single exit path is used in existing air purifiers, then the device structure is simple, but the air distribution is uneven leading to dead zones and prolonged purification time
Solution Approach 1:
The single exit path is segmented into multiple exit paths (first exit path and second exit path) with different orientations. The first exit path directs air axially while the second exit path directs air at an angle between 10-45 degrees relative to the axial direction, creating multiple air circulation patterns that eliminate dead zones and improve overall purification efficiency.
Solution Approach 2:
The air exit configuration transitions from a single-dimensional axial flow to a multi-dimensional flow pattern by introducing a second exit path at an angular orientation. This angular dimension (10-45 degrees relative to axial direction) creates three-dimensional air circulation that covers more spatial areas and eliminates stagnant zones.
2Reliability
If air purifiers run continuously to ensure purification, then air quality improves, but energy consumption increases
Solution Approach 1:
The air purifier incorporates sensors that continuously monitor air quality parameters and provide feedback to the control system. Based on this feedback, the system intelligently adjusts the operation of the air movement device, running at full capacity only when air quality deteriorates and reducing operation when air quality is acceptable, thereby maintaining reliability while reducing unnecessary energy consumption.
Solution Approach 2:
The air movement device operates dynamically rather than statically, with its speed and operation mode adjusted in real-time based on detected air quality conditions. This dynamic operation allows the system to maintain effective purification when needed while consuming less energy during periods of good air quality.
3Area of stationary object
If existing air purifiers use a single air movement direction, then the device structure is simple, but air circulation coverage is limited creating dead spaces
Solution Approach 1:
The single air movement direction is segmented into multiple directional streams through separate exit paths. The first exit path provides axial air movement while the second exit path provides angular air movement (10-45 degrees), creating multiple circulation patterns that collectively cover larger areas and eliminate dead spaces.
Solution Approach 2:
The air circulation system transitions from symmetric single-direction flow to asymmetric multi-directional flow. The second exit path is positioned at an asymmetric angle (10-45 degrees relative to axial direction), creating uneven but comprehensive air distribution that covers areas not reachable by axial flow alone.

AI summary
An air purifier including an air filter, an air movement device configured to move air at least partially in an axial direction and through the filter, and a first exit path in fluid communication with the air movement device. The first exit path is configured such that at least part of the air moved by the air movement device exits the first exit path generally in the axial direction. The air purifier further includes a second exit path in fluid communication with the air movement device and configured such that at least part of the air moved by the air movement device exits the second exit path at an angle of between about 10 degrees and about 45 degrees relative to air exiting the first exit path.
