Solution Overview

Problem

Current cleaning robots with sweeping and mopping integration modes often suffer from moisture issues that damage sweeping modules, miss unswept debris, and create sewage stains, leading to ineffective cleaning.

Innovation Solution

A cleaning robot design featuring separate sweeping and mopping rotation elements with a drive device that allows for independent operation, enabling the robot to switch between sweeping and mopping modes without interference, using detachable modules for enhanced cleaning efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If sweeping and mopping modules operate simultaneously in integration mode, then cleaning efficiency is improved, but moisture from mopping damages sweeping modules and reduces their effectiveness

Engineering Contradiction:

Improvecleaning efficiencyVSAvoidsweeping module effectiveness

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The cleaning robot divides the cleaning function into separate sweeping and mopping modules that can operate independently or be used separately. The sweeping module includes a sweeping rotation element with sweeping brush, while the mopping module includes a mopping rotation element with mopping cloth, allowing users to select appropriate modules based on cleaning needs without cross-contamination between functions

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The robot body is designed to dynamically switch between different module configurations. The sweeping rotation element and mopping rotation element can be independently controlled to rotate, allowing the system to adapt its function based on real-time cleaning requirements rather than being fixed in a single integration mode

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If front sweeping module operates before rear mopping module, then sweeping function is performed, but unswept garbage and dust are missed causing mopping module to become dirty

Engineering Contradiction:

Improvesweeping functionVSAvoidmopping module contamination

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent inverts the traditional sequence by allowing the mopping module to be positioned at the front and sweeping module at the rear, or enabling independent operation where mopping can be performed first on already swept areas, or sweeping can be performed after mopping to ensure complete cleanliness before mopping occurs

Inventive Principle:

Principle #13The other way round (Inversion)

3Productivity

If mopping module operates on floor, then mopping function is performed, but sewage stains are produced on the floor

Engineering Contradiction:

Improvemopping functionVSAvoidsewage stains

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts the water source and wastewater management systems from the mopping module design. The mopping rotation element rotates a mopping cloth to clean the floor without requiring water supply or wastewater discharge mechanisms, thereby eliminating the source of sewage stains while maintaining the mopping function through dry or minimally moist cloth operation

Inventive Principle:

Principle #2Taking out (Extraction)

4Device complexity

If single rotation element is used for both sweeping and mopping, then device complexity is reduced, but cleaning functions interfere with each other and cleaning effect decreases

Engineering Contradiction:

Improvenumber of rotation elementsVSAvoidcleaning effect

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The patent implements universality by designing separate rotation elements (sweeping rotation element and mopping rotation element) that can each serve their specific function optimally, while both can be integrated into the same robot body. This multi-functional design allows the system to perform sweeping, mopping, or either function independently without compromise, rather than forcing a single element to perform multiple conflicting functions

Inventive Principle:

Principle #6Universality (Multi-functionality)
