Autonomous wall cleaner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous wall cleaners require complex structures and sophisticated control systems to navigate uneven surfaces and gaps, as they rely on multiple silicone suckers that need to detach and re-adjust their foothold, making them inefficient and difficult to control.
Innovation Solution
The autonomous wall cleaner employs a combination of suction cups with sliding disks and elastic bowls, Mecanum wheels, and adjustable frames, allowing for improved adhesion and movement on various surfaces, including uneven ones, through a vacuum mechanism and actuated wheels, enabling efficient navigation and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple silicone suckers are used as walking mechanism, then the wall cleaner can adhere to the wall, but the structure becomes complex and requires more than four groups of walking mechanisms
Solution Approach 1:
The patent combines the adhesion function and walking function into a single integrated wheel structure. The suction cup is integrated with the wheel, forming a unified component that performs both functions simultaneously, eliminating the need for separate walking mechanisms and simplifying the overall structure while maintaining reliable wall adhesion
2Ease of operation
If multiple silicone suckers are used for walking, then the wall cleaner can move on the wall, but the control mode becomes complex when encountering uneven surfaces or gaps
Solution Approach 1:
The patent employs dynamically adjustable wheel structures that can automatically adapt to different wall conditions. The wheels can adjust their position and orientation in response to uneven surfaces and gaps, eliminating the need for complex control modes while maintaining easy movement across various wall topographies
3Adaptability or versatility
If silicone suckers detach and re-adjust foothold on uneven surfaces, then the wall cleaner can navigate gaps, but the control system becomes sophisticated and complex
Solution Approach 1:
The wall cleaner features self-adjusting wheels that automatically adapt to uneven surfaces and gaps without requiring sophisticated control systems. The wheels autonomously adjust their position and orientation based on the wall topography, enabling the cleaner to navigate various surfaces while maintaining simple control architecture

AI summary
An autonomous wall cleaner is disclosed. The autonomous wall cleaner comprises a vacuum generator, a number of suction cups, a number of wheels, a number of first actuators, a cleaning element and a controller located on a frame. The wheels are symmetrically arranged on both sides of the frame. The first actuator is capable of driving the wheels. Each suction cup is connected with the vacuum generators and has a sliding disk and an elastic bowl. When the wheels are moving on the wall, the suction cups are sucking to the wall and sliding.
