Mobile Robot Lateral Brush Placement for Increased Working Width
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots have a limited working width due to the placement of their cleaning brushes between two wheels, restricting their effectiveness in cleaning larger surfaces.
Innovation Solution
A mobile robot design where the cleaning brush is mounted laterally and positioned at the widest part of the robot housing, allowing it to extend perpendicular to the forward direction without interference from moving components, thereby increasing the working width and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the cleaning brush is positioned between two wheels in the middle of the robot, then the robot structure is compact and stable, but the extension length of the cleaning brush is limited and the working width is too small
Solution Approach 1:
The cleaning brush is repositioned from a longitudinal arrangement (between wheels) to a lateral arrangement (at the widest part of the housing), extending in the transverse direction rather than the longitudinal direction. This dimensional change allows the brush to utilize the maximum width of the robot body, significantly increasing the working width without interfering with the wheel placement and movement.
2Productivity
If the cleaning brush is extended to increase working width, then the cleaning coverage is improved, but the brush may interfere with the moving components (wheels)
Solution Approach 1:
The cleaning brush is positioned at a specific location (the widest part of the housing, laterally relative to the forward direction) where it can extend to maximum width without interfering with the wheel components. This localized positioning ensures that the brush extension in the transverse direction does not conflict with the longitudinal movement of the wheels, maintaining operational reliability while maximizing cleaning efficiency.

AI summary
A mobile robot. The mobile robot comprises a robot housing (10), two moving components (40), a container apparatus (20), and a cleaning component (50); the moving components are mounted on the robot housing for moving the mobile robot; the cleaning component comprises a main brush (520) provided laterally relative to a normal forward direction (f) of the mobile robot; the main brush is mounted on the robot housing and at or near a part of the robot housing, at which position a transverse width is largest; extension of the main brush in a direction perpendicular to the normal forward direction of the mobile robot is not interfered with by the moving components. The mobile robot has a larger main brush width, and thus the working width of the mobile robot is increased.
