Dual-Module Air Cleaner with Divider to Prevent Discharge Re-Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners have limited capacity and reliability, with restricted air purification due to structural resistance and limited air flow direction, requiring user movement to cover entire indoor spaces and generating increased noise with enhanced fan performance.
Innovation Solution
The air cleaner design incorporates dual blowing devices with cylindrical cases and 360-degree suction ports, a dividing plate to direct airflow radially, and a centrifugal fan with an air guide to enhance airflow directionality and capacity, preventing re-introduction of discharged air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fan blowing amount is increased to improve air purification capacity, then purification performance 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 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) air discharge to multi-directional discharge by adding lateral discharge capability through the second blowing fan. This dimensional expansion allows purified air to reach broader areas without increasing the workload and noise of individual fans.
2Productivity
If single blowing fan is used to simplify device structure, then device complexity is reduced, but blowing capacity is limited
Solution Approach 1:
The blowing function is segmented into multiple fans positioned at different locations with different discharge directions. The first blowing fan discharges air upward while the second blowing fan discharges air laterally, creating a multi-directional airflow pattern that expands purification coverage without requiring excessive power from a single fan.
Solution Approach 2:
Each fan unit serves multiple purposes: the first blowing fan provides upward airflow for general purification, while also working in conjunction with the second blowing fan to create comprehensive air circulation. The dividing plate further enhances this by directing airflow to serve both purification and space coverage functions.
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 curved surface of the cylinder eliminates corner portions that create structural resistance, enabling smoother airflow and improved suction capacity while maintaining manufacturing feasibility through standard cylindrical fabrication processes.
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 as purified air does not reach distant spaces
Solution Approach 1:
The patent adds lateral discharge capability to the traditional upward discharge configuration. The second blowing fan introduces a horizontal airflow dimension, allowing purified air to reach lateral and distant spaces. The dividing plate coordinates this multi-directional flow, ensuring comprehensive coverage without complex control mechanisms.
