Solution Overview

Problem

Current self-moving robots have limited functionality and efficiency in wet cleaning, with mopping effects and efficiency being significantly reduced due to the inability to easily disassemble and maintain their components.

Innovation Solution

A detachable structure is introduced in the self-moving robot, featuring a pressure plate with a connection end and a movable end that can be adjustably clamped to the housing, allowing for quick disassembly and assembly of the cleaning assembly, facilitating maintenance and replacement of components such as the cleaning head and water return mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of repair

If the cleaning assembly is made detachable for easy maintenance, then the ease of repair is improved, but the device complexity increases due to the need for additional detachable structure components

Engineering Contradiction:
Improveease of maintenanceVSAvoidstructure complexity
Core Design Contradiction:
Ease of repairVSDevice complexity

Solution Approach 1:

The cleaning assembly is divided into detachable components including the cleaning head, water supply mechanism, and water return mechanism. These components can be separately removed from the housing through the detachable structure, enabling easy maintenance and replacement of individual parts without disassembling the entire device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A pressure plate with movable end serves as an intermediary component between the cleaning assembly and the housing. The movable end can be adjusted to clamp or release the cleaning assembly, facilitating easy detachment and attachment while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If the cleaning assembly is made detachable for quick maintenance, then the loss of time is reduced, but the device complexity increases due to additional detachable structure components

Engineering Contradiction:
Improvemaintenance timeVSAvoidstructure complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The cleaning assembly is segmented into removable components that can be quickly detached from the housing. The detachable structure allows users to access and maintain individual components such as the cleaning head and water mechanisms without time-consuming disassembly of the entire device.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The detachable structure is designed to enable users to perform maintenance and replacement operations independently without requiring specialized tools or complex disassembly procedures. The movable end of the pressure plate can be easily adjusted to facilitate user-friendly component removal and installation.

Inventive Principle:
Principle #25Self-service

AI summary

A detachable structure and a self-moving robot are provided. The detachable structure is provided in a self-moving robot including a wet cleaning apparatus. The wet cleaning apparatus includes a housing and a cleaning assembly disposed in the housing, and the detachable structure includes: a pressure plate having a connection end and a movable end. The movable end is adjustably clamped to the housing. When the movable end and the housing are in a clamped state, the movable end blocks a partial structure of the cleaning assembly such that the cleaning assembly abuts against the housing; and when the movable end and the housing are in a non-clamped state, the cleaning assembly is removable from the housing.
