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 sweeping robot equipped with a jet dust raising structure that includes a jet channel with an air inlet and outlet, arranged in front of the brush suction port, which uses air flow to raise dust from gaps and narrow spaces, allowing the brush suction port to inhale the dust for improved cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional brush suction port is used, then the structure is simple, but the cleaning ability in ground gaps is poor
Solution Approach 1:
The suction system is segmented into two independent channels: a brush suction port for general surface cleaning and a jet channel for gap cleaning. This segmentation allows each component to specialize in specific cleaning tasks, improving overall cleaning ability while maintaining reasonable structural complexity through modular design.
Solution Approach 2:
The jet channel structure serves multiple functions: it acts as both a dust-raising device and a suction guide. The jet channel's air outlet positions dust particles for suction, while its structure itself guides the airflow pattern, combining dust raising and suction guidance functions in a single component to improve cleaning efficiency without proportionally increasing complexity.
2Speed
If the jet channel cross-sectional area is reduced from air inlet to air outlet, then the air flow velocity increases, but the manufacturing precision requirements increase
Solution Approach 1:
The jet channel employs a gradual cross-sectional area reduction from air inlet to air outlet, creating a diffuser-like structure that accelerates airflow. By controlling the gradient of area reduction rather than using abrupt changes, the design achieves high air flow velocity while maintaining manufacturability and reducing precision requirements compared to sharp transitions.
Solution Approach 2:
The jet channel incorporates curved transitions instead of sharp angular changes in its cross-sectional area reduction. This curved geometry smooths airflow transitions, reduces turbulence, and is more amenable to standard manufacturing processes, thereby achieving high velocity airflow without excessive manufacturing precision requirements.
3Productivity
If the air outlet is positioned close to the brush suction port, then the dust raising efficiency is improved, but the risk of air flow interference increases
Solution Approach 1:
The air outlet is positioned at a specific optimal distance from the brush suction port, and the jet channel's cross-sectional area is locally adjusted near the outlet to control airflow dispersion. This localized optimization ensures dust particles are effectively raised into the suction path while maintaining sufficient separation to prevent harmful airflow interference, balancing efficiency and stability.
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 jet dust raising structure effectively raises dust from both flat and gap areas, enhancing the sweeping robot's ability to clean in narrow spaces and improving overall cleaning efficiency by ensuring dust is absorbed by the brush suction port.
Implementation Method 1
The jet channel has an air inlet and an air outlet. The air inlet is configured for air flow to enter the jet channel. The air outlet is arranged in a front side of a brush suction port of the sweeping robot.
Implementation Method 2
the sweeping robot further includes a dust suction motor. An exhaust port of the dust suction motor is connected with at least one of the air inlet and an air intake of the air inlet chamber of the chassis.
