Multi-Directional Air Cleaner Layout for Wider Purification Coverage
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, requiring user movement to achieve desired coverage.
Innovation Solution
The air cleaner design incorporates dual blowing devices with cylindrical cases and 360-degree suction ports, along with a flow adjusting device that allows air to be suctioned and discharged in multiple directions, enhancing suction capacity and air flow control.
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 single fan system into multiple fans (first blowing fan and second blowing fan). Each fan handles a portion of the air purification task, allowing the system to achieve high purification capacity without requiring any single fan to operate at excessively high speeds that would generate noise and reduce reliability.
2Ease of manufacture
If a rectangular parallelepiped case is used with limited suction ports, then manufacturing is simplified, but suction capacity is reduced due to structural resistance
Solution Approach 1:
The patent segments the air suction function across multiple surfaces of the case (front surface, rear surface, and side surfaces). This allows the rectangular case structure to be maintained for ease of manufacture while significantly increasing suction capacity by distributing intake ports across multiple locations, reducing localized structural resistance.
Solution Approach 2:
The patent transitions from limited suction ports on one or two surfaces to a three-dimensional distribution of suction ports across all surfaces of the rectangular case. This spatial expansion in multiple dimensions allows the simple rectangular structure to achieve high suction capacity without increasing manufacturing complexity.
3Device complexity
If air is discharged in only one upward direction, then the device structure is simplified, but air cleaning coverage is limited to areas around the air cleaner
Solution Approach 1:
The patent segments the air discharge function into multiple discharge paths with different directions. The first air discharge port discharges upward while the second air discharge port discharges in lateral directions. This segmentation allows purified air to reach both areas around the air cleaner and areas farther away, significantly expanding coverage without requiring complex movable structures.
4Device 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 for upward discharge, second blowing fan for lateral discharge). Each fan is responsible for a specific discharge direction and zone, collectively achieving high blowing capacity sufficient for entire indoor space purification while maintaining relatively simple device structure through modular fan units.
