Radial-Suction Air Cleaner Layout for Wider Indoor Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners have limited capacity and reliability due to structural resistance and directional suction, leading to incomplete air purification in indoor spaces, with increased noise and inconvenience from enhanced fan performance.
Innovation Solution
The air cleaner design incorporates dual blowing devices with cylindrical cases and radial suction ports, a flow adjusting device, and a dividing mechanism to improve suction capacity and air distribution, allowing air to be suctioned from multiple directions and discharged in various directions, including forward and lateral directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fan blowing amount is increased to improve air purification performance, then air purification capacity is improved, but noise 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 air purification capacity through coordinated operation of multiple fans rather than overloading a single fan, thus maintaining reliability while improving productivity.
2Productivity
If single blowing fan is used to simplify device structure, then device complexity is reduced, but air purification coverage is limited
Solution Approach 1:
The patent combines multiple blowing fans and multiple discharge ports into an integrated system. The first blowing fan discharges air through the first discharge port, while the second blowing fan discharges air through the second discharge port, creating comprehensive air purification coverage throughout the indoor space.
3Productivity
If rectangular parallelepiped case is used for compact structure, then ease of manufacture is improved, but suction capacity is reduced due to structural resistance
Solution Approach 1:
The patent employs a cylindrical case structure instead of a rectangular parallelepiped. The cylindrical shape eliminates corner portions that create structural resistance, enabling air to be suctioned more efficiently from all directions around the device, thereby significantly improving suction capacity while remaining manufacturable.
4Adaptability or versatility
If air discharge is limited to upward direction to simplify structure, then device complexity is reduced, but air cleaning function is limited to area around cleaner
Solution Approach 1:
The patent transitions from single-direction (upward) air discharge to multi-directional discharge by positioning discharge ports at different locations and orientations. The first discharge port discharges air upward, while the second discharge port discharges air in a different direction, enabling purified air to reach various areas of the indoor space effectively.
