Dual-Module Air Cleaner Layout for 360-Degree Suction 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, and require user movement to achieve desired air purification.
Innovation Solution
The air cleaner design incorporates dual blowing devices with cylindrical cases and 360-degree suction ports, a dividing plate to direct airflow, and a display device for operation information, enhancing suction capacity and air flow directionality while preventing airflow re-introduction.
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 blowing function into multiple 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 maintaining reliability while improving overall purification capacity.
Solution Approach 2:
The patent transitions from single-direction upward discharge to multi-directional discharge by adding a vertical discharge port at the top and horizontal discharge ports at the sides. This dimensional expansion allows purified air to reach multiple areas simultaneously, improving purification coverage without increasing fan blowing amount or noise.
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) rather than relying on a single suction port. This maintains the simple rectangular case structure for ease of manufacture while dramatically increasing suction capacity by utilizing multiple entry points for air intake.
Solution Approach 2:
The patent adds suction ports on vertical side surfaces in addition to traditional horizontal suction ports, transitioning from two-dimensional suction (front and rear only) to three-dimensional suction (front, rear, and sides). This expands air intake capacity without complicating the basic rectangular case structure.
3Device complexity
If air is discharged in only one upward direction, then the device structure is simplified, but air cleaning function is limited as purified air does not reach distant spaces
Solution Approach 1:
The patent segments the air discharge function into multiple discharge ports positioned at different locations and orientations (vertical top port and horizontal side ports). This segmentation allows purified air to be distributed to multiple directions simultaneously, expanding cleaning coverage without significantly increasing structural complexity.
Solution Approach 2:
The patent transitions from single-direction (vertical only) discharge to multi-directional discharge by adding horizontal discharge ports at side surfaces. This dimensional expansion enables purified air to reach both upper and lateral areas, dramatically improving air cleaning coverage throughout the indoor space.
4Device complexity
If a single blowing fan is provided, 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 vertical discharge, second blowing fan connected to horizontal discharge). This segmentation increases total blowing capacity to handle entire indoor space purification while keeping each individual fan relatively simple, balancing complexity and productivity.
