Air Purifier with Multi-Dimensional Intake for Low-Speed Dust Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers do not effectively circulate ambient air without increasing fan speed, leading to inefficient dust removal and high energy consumption.
Innovation Solution
An air purifier design with intakes on the base and top, and outlets on the sides, creating a unique air circulation pattern that enhances dust aggregation and filtration efficiency while reducing fan speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fan speed is increased to improve dust removal efficiency, then dust removal efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent transitions from traditional single-direction air intake (front or bottom) to multi-dimensional air intake by adding both top and bottom air inlets, creating a three-dimensional air circulation pattern. This dimensional change allows air to be drawn from multiple directions simultaneously, increasing the volume of air processed without requiring higher fan speeds, thus improving dust removal efficiency while maintaining lower energy consumption.
Solution Approach 2:
The air intake function is segmented into multiple independent inlets located at different positions (top air inlet and bottom air inlet). Each inlet independently draws air from different zones of the room, and the fan processes the combined airflow. This segmentation allows the system to handle larger air volumes more efficiently without proportionally increasing energy consumption, as the distributed intake reduces resistance and improves airflow distribution.
2Productivity
If fan speed is increased to improve air circulation, then air circulation is improved, but noise increases
Solution Approach 1:
By introducing top and bottom air inlets in addition to front intake, the system creates vertical air circulation loops that were previously absent. This multi-dimensional circulation pattern distributes airflow throughout the room more effectively, achieving superior air circulation performance at lower fan speeds, thereby reducing noise generation from the motor and fan blades.
3Productivity
If traditional air intake configuration is used, then device structure is simple, but air circulation efficiency is poor
Solution Approach 1:
The patent adds vertical dimension to air intake by incorporating top and bottom air inlets, transforming the traditional horizontal single-point intake into a multi-level three-dimensional intake system. This structural enhancement, while adding components, creates efficient air circulation patterns that draw air from different heights and locations, significantly improving air circulation efficiency through better utilization of room space and airflow dynamics.
