Solution Overview

Problem

Existing robot cleaners lack the ability to automatically stop their mopping mode when encountering unsuitable surfaces, such as carpets, which can lead to damage and reduce their reliability.

Innovation Solution

A method and apparatus for controlling a robot cleaner that involves acquiring detection information during a mopping task and controlling the mopping component to stop working and ascend if certain non-mopping conditions are met, such as a non-zero pitch angle or proximity to obstacles, to prevent damage and improve reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the robot cleaner continuously operates in mopping mode, then cleaning productivity is maintained, but reliability deteriorates due to inability to detect unsuitable surfaces like carpets

Engineering Contradiction:
Improvecleaning productivityVSAvoidsystem reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The robot cleaner performs preliminary detection of the cleaning surface before initiating mopping operations. The detection unit scans the surface characteristics ahead of time, and only when the surface is confirmed suitable (non-carpet) does the control unit activate the mopping component, preventing damage before it occurs

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The robot cleaner implements continuous feedback through its detection unit that monitors surface characteristics during operation. When the detection unit identifies a carpet surface, it sends feedback signals to the control unit, which then stops or ascends the mopping component, creating a closed-loop control system that maintains reliability while preserving productivity

Inventive Principle:
Principle #23Feedback

2Reliability

If the robot cleaner adds automatic detection and control capabilities, then reliability improves, but device complexity increases

Engineering Contradiction:
Improvesystem reliabilityVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The robot cleaner employs a multi-functional integrated control unit that combines detection signal processing, mopping component control, and surface type identification in a single device. This universal controller handles multiple functions that would otherwise require separate systems, reducing overall device complexity while maintaining reliability

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The robot cleaner achieves a degree of self-service through its autonomous detection and control system. The detection unit automatically identifies surface types, and the control unit autonomously decides when to stop or ascend the mopping component without human intervention, simplifying the user interface while enhancing reliability

Inventive Principle:
Principle #25Self-service
