Solution Overview

Problem

Existing automatic sweeping robots with mopping functions often leak cleaning fluid when at rest, causing waste and damage to floors.

Innovation Solution

An intelligent cleaning system that includes a moisture-proof mat with an installation unit, which is designed to be installed under the charging station, ensuring that at least a part of the mat is located under the wet cleaning pad when the apparatus is charged.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the automatic sweeping robot is equipped with a water tank for mopping function, then the cleaning capability is improved, but the liquid may leak onto the floor when the robot is at rest, causing waste and damage

Engineering Contradiction:
Improvecleaning capabilityVSAvoidliquid leakage
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

A moisture-proof mat is introduced as an intermediary component between the charging station and the floor. The mat receives and contains any leaking liquid from the water tank, preventing direct contact with the floor. The mat can be easily removed and cleaned, solving the leakage problem without affecting the mopping function.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the moisture-proof mat is installed under the charging station, then the floor protection is improved, but the installation complexity increases

Engineering Contradiction:
Improvefloor protectionVSAvoidinstallation complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The moisture-proof mat is designed as a separate, detachable component from the charging station. The mat can be independently installed, removed, and cleaned without affecting the charging station's functionality. This segmentation simplifies the overall system and makes maintenance easier.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The moisture-proof mat is designed as a simple, inexpensive component that can be easily replaced or cleaned. Rather than making the entire charging station complex and expensive to maintain, the mat serves as a low-cost protective element that can be quickly swapped out if needed.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

AI summary

The disclosure provides a moisture-proof mat (100) for an intelligent cleaning apparatus and an intelligent cleaning system. The intelligent cleaning apparatus is provided with a wet cleaning pad (100). The intelligent cleaning apparatus can be charged by a charging station. The moisture-proof mat (100) may include an installation unit, configured to install the moisture-proof mat (100) to the charging station. At least a part of the moisture-proof mat (100) is configured to be located under the wet cleaning pad (4), when the intelligent cleaning apparatus is charged by the charging station. When the intelligent cleaning apparatus is charged by the charging station, the moisture-proof mat (100) is under the intelligent cleaning apparatus, so that the surface for placing the intelligent cleaning apparatus is less susceptible to moisture and damage.
