Dual-Brush Sweep Module for Low-Power Vacuum Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots face challenges in achieving high cleaning performance without increasing power consumption and noise levels, as they rely solely on vacuum modules for dust and debris removal.
Innovation Solution
A cleaning device with separate sweep and vacuum modules, where a dual-brush design with a main and auxiliary brush pivots to maintain contact with the ground, allowing the sweep module to collect heavy trash and large debris while the vacuum module focuses on dust, reducing the suction force and power consumption, and enhancing cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only the vacuum module is used for cleaning, then the cleaning performance can be maintained, but the power consumption and noise levels increase due to the need for larger suction force
Solution Approach 1:
The cleaning device is divided into two independent modules: a sweep module with rotating brushes for collecting larger debris and particles, and a vacuum module with suction for removing finer dust. This segmentation allows each module to handle specific types of contaminants, reducing the overall power consumption compared to using only a high-power vacuum module for all cleaning tasks.
2Reliability
If only the vacuum module is used for cleaning, then the cleaning function is simplified, but the noise levels increase due to the requirement for larger suction force
Solution Approach 1:
The cleaning device is divided into two independent modules: a sweep module with rotating brushes for collecting larger debris and particles, and a vacuum module with suction for removing finer dust. This segmentation allows each module to handle specific types of contaminants, reducing the overall power consumption compared to using only a high-power vacuum module for all cleaning tasks.
3Productivity
If a brush and vacuum module are combined in a single structure, then the cleaning operation is improved, but the complexity of the device increases
Solution Approach 1:
The cleaning device is divided into two independent modules: a sweep module with rotating brushes for collecting larger debris and particles, and a vacuum module with suction for removing finer dust. This segmentation allows each module to handle specific types of contaminants, reducing the overall power consumption compared to using only a high-power vacuum module for all cleaning tasks.
4Reliability
If the suction force is increased to handle heavy granular powder particles, then the cleaning performance is improved, but the power consumption and noises increase
Solution Approach 1:

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 solution effectively reduces noise and power consumption while improving cleaning performance by allowing the vacuum module to handle only dust, thus lowering the load on the suction motor and enhancing the overall cleaning efficiency.
Implementation Method 1
a portion of the main brush extends out of the casing through the opening and contacts a ground surface
Implementation Method 2
a main brush and an auxiliary brush are pivoted in a casing of the sweep module, and the main brush and the auxiliary brush are driven by a power unit
Implementation Method 3
A suction port is formed below the second chamber, such that the air intake component generates a suction force to draw dust into the second chamber
Implementation Method 4
the air intake component generates a suction force to draw dust into the second chamber
Implementation Method 5
the sweep module freely and pivotally swings under a weight thereof

AI summary
A cleaning device with sweeping and vacuuming functions includes a body accommodating a sweep module and a vacuum module. A main brush and an auxiliary brush driven by a power unit are pivoted in the sweep module. The main brush partially extends outside an opening at a bottom of the sweep module and contacts a ground surface. The sweep module has an outlet adjacent to a top of the auxiliary brush, and is pivoted in the body to freely and pivotally swing under weight. A first chamber of a dust collector of the vacuum module has an inlet corresponding to the outlet, and trash removed by the sweep module is collected into the first chamber. An air inlet communicating with an air intake component is formed above a second chamber of the dust collector. A suction port is formed below the second chamber to draw dust into the second chamber.
