Dual-Module Air Cleaner with 360-Degree Suction for Full-Room 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 intervention to move the device for effective coverage.
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 operational information, enhancing suction capacity and air flow directionality while preventing airflow re-introduction and improving user experience.
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 purification capacity through coordinated operation of multiple fans rather than overloading a single fan, thereby maintaining reliability while improving productivity.
2Ease of manufacture
If a rectangular parallelepiped case is used with limited suction ports, then the 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) with multiple suction ports distributed throughout. This maintains the simple rectangular case structure for ease of manufacture while dramatically improving suction capacity by eliminating the bottleneck of limited suction ports.
Solution Approach 2:
The patent transitions from limited suction ports on specific surfaces to a three-dimensional distribution of suction ports across all surfaces of the case. This dimensional expansion of air intake pathways overcomes the structural resistance problem while preserving the simple rectangular case design.
3Device complexity
If air discharge is limited to one direction, then the device structure is simplified, but air cleaning coverage in the entire indoor space is limited
Solution Approach 1:
The patent segments the air discharge function into multiple discharge ports positioned at different locations and orientations (front discharge port, rear discharge port, side discharge ports). This segmentation enables purified air to be distributed in multiple directions simultaneously, achieving comprehensive indoor space coverage without requiring complex movable or adjustable mechanisms.
4Device complexity
If a single blowing fan is used, then the device complexity is reduced, but blowing capacity is limited
Solution Approach 1:
The patent divides the blowing function into multiple independent fans (first blowing fan connected to first discharge port, second blowing fan connected to second discharge port). This segmentation allows each fan to operate independently at optimal performance levels, achieving high total blowing capacity while keeping each individual fan unit simple and manageable.
