Dual-Module Air Cleaner with Cylindrical Cases for 360-Degree Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners have limited capacity and reliability due to structural resistance and directional suction, resulting in incomplete air purification and increased noise when trying to improve fan performance, requiring 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 device, and a flow adjusting mechanism to enhance suction capacity and air distribution, preventing re-introduction of discharged air and improving spatial utilization with a centrally located PCB device.
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 air purification capacity to be increased through multiple units working together rather than overloading a single fan, thus maintaining lower noise levels and higher reliability for each individual fan unit.
2Productivity
If single directional discharge is used to simplify device structure, then device complexity is reduced, but air distribution coverage is limited
Solution Approach 1:
The patent segments the air discharge function into multiple discharge ports (first discharge port in upper portion, second discharge port in lower portion) with different discharge directions. This allows purified air to be distributed to different spatial zones simultaneously, expanding coverage without requiring complex adjustable mechanisms.
Solution Approach 2:
The patent adds vertical dimension to air discharge by providing both upper and lower discharge ports with different discharge directions (upward and lateral/downward). This multi-dimensional discharge approach expands air distribution coverage throughout the indoor space without increasing horizontal complexity.
3Productivity
If rectangular parallelepiped case shape is used for compact design, then ease of manufacture is improved, but suction capacity is reduced due to structural resistance
Solution Approach 1:
The patent employs a cylindrical case shape instead of a rectangular parallelepiped. The curved cylindrical surface eliminates corner portions that create structural resistance, enabling smoother air flow and higher suction capacity. The cylindrical shape is also easily manufacturable using standard molding techniques.
