Cleaning Robot Multi-Brush Switching for Automatic Surface Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots are limited to a single roller brush, which requires manual replacement for efficient cleaning of multi-material surfaces, and existing solutions lack automatic adaptation to different floor types.
Innovation Solution
A cleaning robot equipped with a roller brush assembly comprising at least two roller brushes, a detection assembly to identify surface type, and a control assembly to automatically switch between the brushes based on detected surface type, using sound or light waves for identification.

Engineering Contradiction Analysis
1Productivity
If the cleaning robot moves at high speed to improve cleaning efficiency, then productivity increases, but the robot may collide with obstacles or fall down, worsening reliability
Solution Approach 1:
The robot performs preliminary actions by predicting future positions and obstacles before actual movement occurs. The prediction unit calculates where the robot will be in the future based on current speed and direction, and identifies obstacles that will be in those future positions, allowing the robot to adjust its path proactively rather than reactively
Solution Approach 2:
The control unit continuously receives feedback from the prediction unit about future collision risks and adjusts the robot's speed and direction in real-time. This closed-loop control ensures that the robot maintains high productivity while dynamically adapting to prevent collisions and falls
2Measurement precision
If the robot increases sensor coverage to improve detection accuracy, then measurement precision improves, but device complexity increases
Solution Approach 1:
The imaging unit serves multiple functions: it detects obstacles, determines their locations, and provides data for prediction calculations. This multi-functional approach achieves comprehensive detection coverage without proportionally increasing system complexity, as a single imaging unit performs what would otherwise require multiple specialized sensors
