Multi-Module Air Cleaner for 360-Degree Suction and Wide Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners have limited capacity and reliability, with reduced suction capacity due to structural resistance and limited air flow direction, resulting in incomplete air purification in indoor spaces, and increased noise when trying to improve fan performance.
Innovation Solution
The air cleaner design incorporates multiple blowing devices with cylindrical cases and 360-degree suction ports, a flow adjusting device, and a centrifugal fan to enhance suction and discharge air flow in various directions, including upward, forward, and lateral directions, while preventing air recirculation and improving filter accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the blowing amount of the fan is increased to improve air purification performance, then the purification capacity is improved, but noise generated by the fan increases and reliability decreases
Solution Approach 1:
The patent divides the air blowing function into multiple independent fans (first blowing fan and second blowing fan) positioned at different locations. This segmentation allows the system to achieve high total airflow without requiring any single fan to operate at high noise-generating speeds, thus improving air purification capacity while maintaining reliability and reducing noise.
2Ease of manufacture
If a rectangular parallelepiped case is used for structural simplicity, then manufacturing is easier, but suction capacity is reduced due to structural resistance at corner portions
Solution Approach 1:
The patent employs curved guide ribs with rounded surfaces instead of sharp corner structures. The guide ribs feature leading edges and side surfaces that are curved rather than angular, reducing air flow resistance and turbulence at critical junctions. This curvature design maintains manufacturing feasibility while significantly improving air suction capacity by eliminating dead zones and reducing structural resistance.
3Device complexity
If air suction ports are limited to side and lower portions, then device complexity is reduced, but suction capacity is reduced due to limited suction directions
Solution Approach 1:
The patent designs the case with air suction ports distributed across multiple surfaces (side surfaces and lower portions), enabling the device to draw air from various directions simultaneously. This multi-directional suction configuration increases the effective suction capacity without significantly increasing device complexity, as the ports are integrated into the existing case structure.
4Device complexity
If air is discharged in only one upward direction, then device complexity is reduced, but air cleaning function is limited as purified air does not reach distant spaces
Solution Approach 1:
The patent transitions from single-direction (vertical) air discharge to multi-directional discharge by positioning separate discharge ports at different locations and orientations. The first air discharge port discharges upward while the second air discharge port discharges in lateral directions, creating a three-dimensional air distribution pattern that expands purification coverage throughout the indoor space without complex mechanical adjustment mechanisms.
5Device complexity
If a single blowing fan is used, then device complexity is reduced, but blowing capacity is limited and cannot purify entire indoor space
Solution Approach 1:
The patent divides the blowing function into multiple independent fans (first blowing fan connected to first air discharge port, second blowing fan connected to second air discharge port). This segmentation enables each fan to serve specific discharge directions and zones, collectively achieving comprehensive indoor space purification with enhanced total blowing capacity while keeping individual fan units simple and manageable.
