Solution Overview

Problem

Existing autonomous cleaning robots require the bottom to be turned upside down for installing or disassembling the water tank, making the process inconvenient and prone to leaks, which complicates user interaction and maintenance.

Innovation Solution

The autonomous cleaning robot features a removable and connectable cleaning assembly with a buckle and groove mechanism, allowing the liquid container to be inserted horizontally into the chassis without flipping the robot, ensuring easy installation and disassembly, and incorporating an obstacle-assisting wheel for improved obstacle navigation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the water tank is connected to the robot at the bottom, then the water source is provided, but the bottom needs to be turned upside down for installation or disassembly

Engineering Contradiction:
Improveease of water tank installationVSAvoidoperation complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent inverts the traditional bottom-mounted water tank design by positioning the water tank at the front end of the robot body. The connection interface is located at the front, allowing users to install or remove the water tank by simply pushing or pulling it horizontally without needing to flip the robot upside down. This inversion of the mounting location fundamentally changes the operation from complex (requiring inversion) to simple (horizontal insertion/removal).

Inventive Principle:
Principle #13The other way round (Inversion)

2Reliability

If the water tank is connected at the bottom, then the structure is stable, but the process is prone to leaks

Engineering Contradiction:
Improvesealing reliabilityVSAvoidease of water tank maintenance
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By moving the water tank connection from the bottom to the front end, the patent eliminates the need to invert the robot for maintenance. The front-mounted connection allows users to access and service the water tank while the robot remains in its normal upright position, preventing leaks that could occur during inversion and simplifying maintenance procedures.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The water tank is designed as a removable, modular component that can be easily separated from the main robot body through a connection interface at the front. This segmentation allows the water tank to be independently installed, removed, and maintained without affecting the rest of the robot structure, improving both reliability and ease of maintenance.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If the cleaning assembly is fixed, then the structure is stable, but the maintenance becomes difficult

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of cleaning assembly maintenance
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The cleaning assembly is designed as a removable module that can be detached from the robot body through a connection interface. During operation, the cleaning assembly remains firmly connected to maintain structural stability and cleaning effectiveness. When maintenance is needed, the cleaning assembly can be easily separated and serviced without disassembling the entire robot, thus achieving both structural stability during use and ease of maintenance when needed.

Inventive Principle:
Principle #1Segmentation
