Cleaning Robot Wet Assembly Hijacking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cleaning robots face issues with hijacking, leading to inconsistent cleaning, secondary pollution, and reduced efficiency due to improper handling of wet cleaning assemblies during and after hijacking events.
Innovation Solution
Implementing a time or distance threshold before retracting the wet cleaning assembly to prevent frequent retraction and deployment, ensuring the assembly remains in the appropriate state based on the surface type post-hijacking, and adjusting dry cleaning operations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the wet cleaning assembly is retracted immediately after hijacking detection, then the risk of contamination and secondary pollution is reduced, but the lifespan of the wet cleaning assembly is reduced due to frequent retraction and deployment
Solution Approach 1:
The system performs preliminary judgment of the operating surface material before retracting the wet cleaning assembly. By detecting whether the surface is carpet or hard floor in advance, the system avoids unnecessary retraction on hard floors where contamination risk is low, thereby reducing frequent operations while preventing contamination when needed on carpets.
Solution Approach 2:
The system uses feedback from the operating surface material detection to dynamically control the wet cleaning assembly state. The detection result of the surface material feeds back to the control unit, which then decides whether to retract or maintain the wet cleaning assembly, creating a closed-loop control that optimizes both contamination prevention and component lifespan.
2Object-affected harmful factors
If the wet cleaning assembly is retracted immediately after hijacking detection, then contamination is prevented, but cleaning efficiency is reduced due to frequent retraction and deployment operations
Solution Approach 1:
The system performs preliminary detection of the operating surface material before executing retraction. This advance judgment prevents unnecessary retraction operations on hard floors where secondary pollution risk is minimal, thereby maintaining cleaning efficiency while still preventing contamination when required on carpets.
Solution Approach 2:
The system changes the operational parameter of the wet cleaning assembly (retracted vs. extended state) based on the detected surface material parameter. This dynamic parameter adjustment optimizes the balance between preventing secondary pollution and maintaining cleaning efficiency by adapting to different surface types.
3Duration of action of stationary object
If the wet cleaning assembly state is not adjusted after hijacking, then the lifespan of the assembly is preserved, but contamination and secondary pollution occur due to mismatched assembly state and surface material
Solution Approach 1:
The control unit receives feedback from the operating surface material detection and adjusts the wet cleaning assembly state accordingly. This feedback mechanism ensures the assembly is retracted only when necessary (on carpets), preventing contamination while minimizing unnecessary operations that would reduce assembly lifespan.
Solution Approach 2:
The system dynamically changes the state parameter of the wet cleaning assembly based on the detected surface material. This parameter adjustment ensures the assembly operates in the appropriate state (retracted or extended) matched to the surface type, preventing contamination without excessive retraction operations.
4Duration of action of stationary object
If a time threshold is introduced before retraction, then the lifespan of the wet cleaning assembly is improved by reducing frequent operations, but the response time to prevent contamination is delayed
Solution Approach 1:
The system performs preliminary detection of the operating surface material before the hijacking event concludes. By having the material detection capability ready in advance, the system can make rapid decisions about retraction without requiring extended observation time, thus balancing response time with reduced operation frequency.

AI summary
The present disclosure provides a control method for cleaning robot, the method comprises: in case where a wet cleaning assembly performs a cleaning task on the operating surface at least in a mopping state, the cleaning robot is being hijacked and the time of being hijacked is greater than a preset time, the wet cleaning assembly changes from the mopping state to a mop folding state, wherein the being hijacked means that the cleaning robot leaves the operating surface; the cleaning robot quits being hijacked and continues to perform the cleaning task, in case where the operating surface is a floor or ceramic tile, the cleaning assembly switches from the mop folding state to the mopping state; in case where the operating surface is a carpet, the cleaning assembly remains in the mop folding state, the mopping state means that the mop is in the state of being released.
