Control method for cleaning robot
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, and adjusting the wet cleaning assembly operation according to the material of the operating surface, ensuring the cleaning robot performs appropriate cleaning tasks based on the surface type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wet cleaning assembly is retracted immediately after hijacking detection, then the cleaning robot avoids secondary pollution and maintains cleaning consistency, but the assembly lifespan is reduced and user injury risk increases due to frequent retraction and deployment
Solution Approach 1:
The patent applies dynamics by making the retraction decision conditional rather than fixed. The control unit dynamically evaluates whether the hijacking event is temporary or sustained by comparing the duration against a threshold value. This dynamic approach allows the system to adapt its behavior based on real-time conditions, retracting only when necessary while maintaining the assembly in working state for brief interruptions, thereby balancing cleaning consistency with assembly lifespan preservation.
2Reliability
If the wet cleaning assembly is retracted immediately after hijacking detection, then the cleaning robot avoids secondary pollution and maintains cleaning consistency, but user safety is compromised due to increased risk of hand pinching during frequent retraction and deployment
Solution Approach 1:
The system dynamically adjusts its response to hijacking events by introducing a time-based threshold. Instead of immediately retracting the wet cleaning assembly upon detecting hijacking, the control unit monitors the duration of the hijacking state. This dynamic evaluation reduces unnecessary retraction operations, thereby minimizing opportunities for user injury while maintaining cleaning consistency through selective retraction only when the hijacking state persists beyond the threshold.
3Reliability
If the wet cleaning assembly is retracted immediately after hijacking detection, then the cleaning robot avoids water tank leakage and assembly damage, but cleaning efficiency is reduced due to frequent retraction and deployment
Solution Approach 1:
The patent implements a dynamic decision-making mechanism that evaluates the duration of hijacking events before triggering retraction. By introducing a threshold comparison, the system distinguishes between temporary interruptions (which do not require retraction) and sustained hijacking events (which do require retraction). This dynamic approach preserves cleaning efficiency by avoiding unnecessary retraction operations while still protecting the assembly from damage during genuine prolonged hijacking scenarios.
4Duration of action of stationary object
If the cleaning robot resumes cleaning task immediately after hijacking without retraction, then assembly lifespan and user safety are preserved, but secondary pollution occurs and cleaning consistency is lost
Solution Approach 1:
The system employs a dynamic threshold-based evaluation to determine whether retraction is necessary. By monitoring the duration of the hijacking state and comparing it against a predefined threshold, the control unit makes an intelligent decision: retracting the wet cleaning assembly only when the hijacking persists long enough to pose a risk of secondary pollution, while allowing immediate resumption for brief interruptions. This dynamic approach prevents secondary pollution without causing unnecessary retraction operations.

AI summary
The present disclosure provides a control method for cleanign 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.
