Electric cleaning brush
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric cleaning brushes face difficulties in controlling the direction of the brush broom due to coaxial arrangement of the motor shaft and brush broom, leading to significant vibrations and low cleaning efficiency.
Innovation Solution
The electric cleaning brush design features a motor and rolling brush arranged coaxially and horizontally, with the motor inside the rolling brush, allowing horizontal rotation and adjustable angle and strength control via coil springs, and a synchronously rotating output shaft and roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the motor shaft and brush broom are coaxially arranged, then the structure is simple, but the direction of the brush broom is difficult to control and vibrations are significant
Solution Approach 1:
The patent changes the spatial arrangement from coaxial (one-dimensional alignment) to perpendicular arrangement where the motor shaft and brush broom axis are at right angles. This dimensional change allows the brush broom to rotate freely in the horizontal plane while the motor provides vertical driving force, resolving the direction control issue while maintaining structural simplicity.
2Device complexity
If the motor shaft and brush broom are coaxially arranged, then the structure is simple, but significant vibrations occur during cleaning
Solution Approach 1:
By arranging the motor shaft perpendicular to the brush broom axis, the patent separates the motor's rotational force vector from the brush broom's rotational plane. This dimensional separation prevents the transmission of motor vibrations to the brush broom, eliminating the harmful vibrations while keeping the structure simple.
3Device complexity
If the motor is located behind the brush broom, then the structure is conventional, but cleaning efficiency is low
Solution Approach 1:
The patent repositions the motor from a rear-mounted conventional arrangement to a side-mounted perpendicular arrangement. This spatial reconfiguration allows the brush broom to rotate in the horizontal plane for better ground contact and cleaning coverage, significantly improving cleaning efficiency while maintaining a simple structural arrangement.
