Sweeping Robot Jet Dust-Lifting Structure for Ground Gap Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sweeping robots are unable to effectively clean dust from ground gaps, limiting their cleaning efficiency and ability to meet user needs.
Innovation Solution
A jet dust raising structure is integrated into the sweeping robot, featuring a jet channel that runs through the top and bottom of the chassis, allowing air flow to be ejected in front of the brush suction port to lift dust from gaps, which is then inhaled by the suction port, enhancing the robot's cleaning ability in narrow spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional brush suction port is used for cleaning, then the structure is simple and easy to manufacture, but the cleaning ability on ground gaps is poor
Solution Approach 1:
The patent combines the air blowing function and dust suction function into a single integrated structure. The air outlet is positioned directly in front of the brush suction port, creating a coordinated system where blown air lifts dust and the suction port simultaneously absorbs it, improving cleaning ability without significantly increasing overall structural complexity
Solution Approach 2:
The patent introduces air flow as an intermediary medium between the ground surface and the suction port. The air outlet blows air onto the ground surface to lift dust particles, and this air flow acts as a mediator to transport dust from gaps toward the suction port, enhancing the suction effect in narrow spaces
2Reliability
If the air outlet blows air to raise dust, then dust in gaps can be lifted and cleaned, but energy consumption increases
Solution Approach 1:
The patent merges the air blowing and dust suction functions into a coordinated system where the air outlet and brush suction port work together. The air flow lifts dust and simultaneously directs it toward the suction port, creating a synergistic effect that improves dust collection capacity while optimizing energy utilization through the integrated design
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 improves the sweeping robot's efficiency and cleaning ability by allowing it to effectively absorb dust from gaps, increasing the dust collection capacity and overall cleaning performance.
Implementation Method 1
The air flow enters the jet channel from the air inlet, and then is ejected at the air outlet after passing through the jet channel to raise the dust in front of the brush suction port
