Solution Overview

Problem

Cleaning robots lack a self-cleaning function, requiring manual cleaning of their mopping and wiping members after each use, which is time-consuming and laborious, affecting user experience.

Innovation Solution

A self-cleaning method and system for cleaning robots that includes a control module to switch between operating and self-cleaning modes, where the cleaning device operates and the driving device stops, allowing the robot to clean its components automatically, such as the roller brush, using a docking station with a cleaning groove for efficient self-cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the cleaning robot is equipped with only floor cleaning function, then the device complexity is low, but the ease of operation deteriorates due to manual cleaning requirement

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cleaning robot is equipped with a self-cleaning function that allows it to clean its own roller brush and mopping members automatically. The control module switches between operating mode and self-cleaning mode, enabling the robot to serve itself without human intervention, thus improving ease of operation while accepting increased device complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning robot is designed with multi-functionality, combining both floor cleaning and self-cleaning functions in a single device. The cleaning device can operate in two distinct modes: cleaning the floor and cleaning the robot's own components. This universal design allows one device to perform multiple functions, improving ease of operation by eliminating the need for separate manual cleaning processes

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

2Productivity

If manual cleaning of mopping and wiping member is required, then the device complexity is low, but loss of time increases due to time-consuming manual cleaning

Engineering Contradiction:
ImproveproductivityVSAvoidloss of time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The self-cleaning function allows the cleaning robot to automatically clean its own roller brush and mopping members by rotating the roller brush against the cleaning groove and using water from the water tank. This self-service capability eliminates the time-consuming manual cleaning process, significantly improving productivity by reducing the time users need to spend on maintenance tasks

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The self-cleaning process is performed automatically after the operating mode, preparing the roller brush and mopping members for the next cleaning task without requiring user intervention. This preliminary action ensures the cleaning components are ready for immediate use, improving productivity by eliminating downtime between cleaning operations

Inventive Principle:
Principle #10Preliminary action
