Solution Overview

Problem

Existing cleaning robots are limited to single-function operations, requiring separate robots for sweeping and mopping, which occupy space and cannot effectively clean stubborn stains.

Innovation Solution

A vibratile mop with a movable region and flexible connection to a fixed region, allowing reciprocating motion, integrated with a cleaning apparatus that includes both dry and wet cleaning modules for simultaneous sweeping and mopping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single-function cleaning robot is used for either sweeping or mopping, then the structure is simple and space is occupied by only one robot, but the cleaning effectiveness on stubborn stains is insufficient and multiple robots are required

Engineering Contradiction:
Improvecleaning function versatilityVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines both sweeping and mopping functions into a single cleaning robot by integrating a dry cleaning module (sweeping brush) and a wet cleaning module (mop) with a vibratile mop head. This merging allows the robot to perform both dry and wet cleaning operations simultaneously or sequentially, eliminating the need for separate single-function robots while maintaining manageable structural complexity through modular design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cleaning robot is designed as a universal cleaning device that can adapt to different cleaning needs. The wet cleaning module with the vibratile mop head can handle both light and stubborn stains, while the dry cleaning module handles dry debris. The robot can switch between different cleaning modes and attach different cleaning modules based on the cleaning requirements, making it a multi-functional universal cleaning solution.

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

2Productivity

If a single-structure mop is used, then the structure is simple and the cleaning robot can move freely, but the mop can only passively clean with the movement of the robot and cannot effectively clean regions with more stains

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidmop structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The mop head is designed as a vibratile (dynamic) structure that can reciprocate relative to the cleaning substrate. The movable region of the mop head is capable of substantial reciprocation driven by a driving mechanism, transforming the passive cleaning action into an active vibratile motion. This dynamic motion allows the mop to effectively clean stubborn stains by repeatedly working on the same area, significantly improving cleaning effectiveness compared to static single-structure mops.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mop head is segmented into a fixed region and a movable region connected by a flexible connecting portion. The movable region can reciprocate independently while the fixed region remains stationary, allowing different parts of the mop to perform different functions. This segmentation enables the mop to combine the stability of a fixed structure with the cleaning effectiveness of a dynamic moving structure.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If both sweeping and mopping robots are prepared to clean the ground simultaneously, then comprehensive cleaning is achieved, but double space is occupied and arrangement of other components is affected

Engineering Contradiction:
Improvecleaning coverageVSAvoidspace occupation
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The invention merges the functions of separate sweeping and mopping robots into a single integrated cleaning robot. The robot includes both a dry cleaning module for sweeping and a wet cleaning module for mopping, allowing it to perform comprehensive cleaning tasks that previously required two separate devices. This consolidation reduces space occupation while maintaining full cleaning coverage.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A vibrating mop and an automatic cleaning device. The vibrating mop comprises a moving area (412) and a fixed area (411), the moving area (412) and the fixed area (411) being connected by means of a flexible connecting part (413), and the moving area (412) being capable of making a substantially reciprocating movement relative to the fixed area (411). As the moving area (412) of the vibrating mop can make a substantially reciprocating movement with a vibrating apparatus, a given area can be cleaned repeatedly.
