Solution Overview
Problem
Existing cleaning robot systems face performance degradation due to inefficient dust collection and maintenance, leading to reduced cleaning effectiveness and increased operational costs.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If dust is stored in a dust box during cleaning operations, then cleaning capacity is improved, but cleaning performance degrades over time due to dust accumulation
Solution Approach 1:
The maintenance station enables the robot cleaner to automatically discharge its own dust without user intervention. The system uses the existing brush unit opening for dust discharge, and the brush unit itself assists in the discharge process by rotating to propel dust outward, creating a self-maintaining system.
Solution Approach 2:
The system automatically discards accumulated dust from the dust box at the maintenance station. The dust is discharged through the brush unit opening using airflow generated by the maintenance station, and the brush unit rotation assists in propelling dust outward, enabling periodic recovery of cleaning performance.
2Ease of operation
If the robot cleaner operates autonomously without user intervention, then ease of operation is improved, but maintenance complexity increases
Solution Approach 1:
The brush unit opening serves multiple functions: it allows the brush unit to contact the floor during cleaning operations and serves as the dust discharge path during maintenance. The brush unit itself performs dual functions of cleaning during operation and assisting dust discharge during maintenance by rotating to propel dust outward.
Solution Approach 2:
The robot cleaner automatically docks with the maintenance station and performs dust discharge without user intervention. The system uses its own brush unit rotation capability to assist in the dust discharge process, reducing the need for additional complex maintenance mechanisms.
3Device complexity
If dust is discharged through the opening where the brush unit is installed, then device complexity is reduced, but dust discharge efficiency may be affected by brush interference
Solution Approach 1:
The brush unit, which could potentially obstruct dust discharge through the opening, is instead utilized as an active component to assist discharge. By rotating the brush unit, dust is propelled outward through the opening, converting a potential obstacle into a beneficial discharge mechanism that works together with the airflow from the maintenance station.
Solution Approach 2:
The single opening serves dual purposes: allowing brush contact with the floor during cleaning and serving as the dust discharge path during maintenance. The brush unit similarly performs dual functions of floor cleaning and dust discharge assistance, eliminating the need for separate openings or mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system maintains high cleaning performance by efficiently discharging and removing dust, reducing maintenance needs, and enhancing operational efficiency through automatic dust management.
Implementation Method 1
dust stored in a dust box is suspended in air introduced into the dust box through a first opening
Implementation Method 2
dust stored in a dust box is suspended in air introduced into the dust box through a first opening formed through a robot cleaner, and is then discharged to a second opening formed through a maintenance station through the first opening of the robot cleaner
Implementation Method 3
maintenance station blows air into a dust box included in a robot cleaner through an opening of the robot cleaner where a brush unit is installed, and sucks dust stored in the dust box while being suspended in the air blown into the dust box
