Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot cleaners face performance deterioration due to fan malfunctions and filter clogging from trapped contaminants, limiting their cleaning efficiency and power consumption.
Innovation Solution
A cleaning apparatus with a brush unit, a blowing unit, and a dust collecting unit that includes separate inlets and storage spaces, a guide member, and a brush cleaning member to efficiently collect and separate dust, reducing the burden on the fan and filter, and allowing for easy dust removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the fan and filter are installed in a compact robot cleaner body, then the cleaning apparatus can operate autonomously with integrated components, but the fan may break down due to contaminants trapped therein or the filter may be clogged by contaminants
Solution Approach 1:
The dust collecting unit is divided into multiple storage spaces (first storage space for large dust particles, second storage space for fine dust particles) with separate inlets. This segmentation prevents different types of contaminants from mixing and accumulating in the same location, reducing the burden on the fan and filter while maintaining reliable operation in the compact robot cleaner body.
2Volume of moving object
If the robot cleaner has a limited size, then it can navigate and travel autonomously in cleaning areas, but the performances of the fan and filter are changed according to installation positions, affecting cleaning performance
Solution Approach 1:
By segmenting the dust collection system into multiple specialized storage spaces with dedicated inlets positioned at different locations, the system optimizes contaminant collection efficiency for each space constraint. The first inlet collects large particles while the second inlet collects fine particles, ensuring both fan and filter operate at optimal performance despite the compact installation positions required for autonomous navigation.
3Device complexity
If a single dust collecting unit is used, then the structure is simple, but dust collection efficiency is reduced due to mixed contaminant accumulation
Solution Approach 1:
The dust collecting unit is segmented into multiple storage spaces (first storage space and second storage space) with separate inlets for different particle sizes. This internal segmentation maintains the simplicity of a single removable dust collecting unit while significantly improving dust collection efficiency by preventing mixed contaminant accumulation and enabling targeted collection of large dust particles and fine dust particles separately.

AI summary
A cleaning apparatus and a dust collecting method using the same are provided. The cleaning apparatus includes a body, a brush unit rotatably provided at the body, a dust collecting unit to store contaminants, such as dust, swept by the brush unit, and a blowing unit to suction contaminants, such as dust, scattered by the brush unit and to move the suctioned contaminants to the dust collecting unit.
