Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic cleaning devices often result in poor cleaning effects due to missing cleaning areas when making turns, particularly near obstacles like walls and furniture.
Innovation Solution
The automatic cleaning device performs supplementary cleaning movements, including backward and forward movements, after each rotation by a preset angle during direction switching to ensure complete coverage and avoid obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the automatic cleaning device performs direction switching by rotating to avoid obstacles, then the device can navigate around obstacles, but cleaning coverage is reduced and missing cleaning areas are created
Solution Approach 1:
The cleaning device performs preliminary cleaning actions at the current position before initiating rotation for obstacle avoidance. The cleaning assembly continues to clean the ground during the rotation process, ensuring that cleaning coverage is maintained even while navigating around obstacles.
Solution Approach 2:
The cleaning assembly operates continuously during the direction switching process. Instead of stopping cleaning when rotating to avoid obstacles, the system maintains continuous cleaning action, eliminating idle time and ensuring complete coverage of the cleaning area including regions near obstacles.
2Productivity
If the cleaning assembly protrudes from the outer edge of the machine body to increase cleaning width, then cleaning efficiency is improved, but the device may collide with obstacles more frequently
Solution Approach 1:
The sensing apparatus detects obstacles in advance before the protruding cleaning assembly can collide with them. This early detection allows the control system to initiate direction switching maneuvers proactively, preventing collisions while maintaining the extended cleaning width provided by the protruding assembly.
Solution Approach 2:
The sensing apparatus provides continuous feedback about the environment to the control system. When obstacles are detected within a preset range, the system receives feedback signals and automatically adjusts the rotation speed and cleaning assembly position to avoid collisions, enabling the protruding cleaning assembly to operate safely at extended reach.

AI summary
A method for controlling an automatic cleaning device includes in response to the automatic cleaning device moving into a preset range of an obstacle and performing direction switching, controlling the automatic cleaning device to perform supplementary cleaning movement once after each rotation of the automatic cleaning device by a preset angle until the automatic cleaning device completes the direction switching, where the supplementary cleaning movement includes backward movement and forward movement.
