Cylindrical Air Cleaner Layout for 360-Degree Intake Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners have limited capacity to purify air across an entire indoor space due to structural design limitations, resulting in reduced suction capacity and limited air flow directionality, which decreases their effectiveness in cleaning corners and areas away from the device.
Innovation Solution
The air cleaner incorporates a cylindrical design with multiple suction ports along its circumference for 360-degree air intake and features dual blowing devices with a flow adjusting mechanism, allowing for enhanced air suction and directional air discharge, including upward, forward, and lateral directions, to improve coverage and efficiency.
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 productivity.
Solution Approach 2:
The patent introduces directional diversity by positioning fans to blow air in different directions (upward direction via first blowing fan, forward and lateral directions via second blowing fan). This multi-dimensional air distribution enables comprehensive space coverage without increasing individual fan workload excessively.
2Productivity
If a single blowing fan is used to simplify the device structure, then the device complexity is reduced, but the blowing capacity and air flow distribution are limited
Solution Approach 1:
Each fan unit is designed to serve multiple functions: the first blowing fan provides upward air flow for general circulation, while the second blowing fan provides forward and lateral air flow for corner coverage. This multi-functionality allows the system to achieve comprehensive air distribution without requiring overly complex specialized components.
Solution Approach 2:
The blowing system is segmented into multiple independent fan units with distinct functions and positions. This segmentation enables each fan to operate efficiently within its optimized range while collectively achieving high blowing capacity and versatile air flow distribution patterns.
3Area of stationary object
If air is discharged in only one upward direction to simplify the discharge structure, then the device complexity is reduced, but the air cleaning function is limited as purified air does not reach distant spaces
Solution Approach 1:
The patent transitions from single-direction (vertical) air discharge to multi-directional air discharge by positioning the second blowing fan to release air in forward and lateral directions. This dimensional expansion of air flow patterns enables purified air to reach corners and distant spaces throughout the indoor environment.
Solution Approach 2:
The air discharge system is made dynamically adaptable to different spatial requirements through the coordinated operation of multiple fans with different discharge orientations. This dynamic configuration allows the system to effectively cover various areas including corners and distant spaces without requiring complex mechanical adjustment mechanisms.
4Productivity
If a rectangular parallelepiped case structure is used for simplicity, then the ease of manufacture is improved, but corner portions create structural resistance that reduces suction capacity
Solution Approach 1:
The patent employs a cylindrical case structure instead of a rectangular parallelepiped. This curved, corner-free geometry eliminates structural resistance at corners that would otherwise impede air suction, thereby maximizing suction capacity while remaining manufacturable using standard cylindrical forming processes.
