Solution Overview

Problem

Existing floor scrubbers face challenges in achieving a compact structural layout, which affects their efficiency and safety during maintenance, as well as the even distribution of cleaning liquid during operation.

Innovation Solution

The cleaning device incorporates a pivotally connected device body with a wastewater tank and power source arranged in a horizontal direction to enhance safety and compactness, and features a liquid dispensing connector with varying liquid outlet calibers to ensure uniform liquid distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the wastewater tank and power source are arranged in the same longitudinal direction as the device body, then the structural layout is simpler, but the device becomes less compact and maintenance safety is reduced

Engineering Contradiction:
Improvestructural layoutVSAvoiddevice compactness
Core Design Contradiction:
Device complexityVSVolume of moving object

Solution Approach 1:

The patent applies dimensional reorganization by arranging the wastewater tank and power source in the horizontal direction (transverse to the device body's longitudinal axis) rather than sequentially along the longitudinal direction. This spatial reconfiguration reduces the device's overall length and improves compactness while maintaining structural clarity through orthogonal arrangement.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of repair

If the fan is exposed for easier maintenance access, then maintenance ease is improved, but safety during maintenance deteriorates due to accidental contact risk

Engineering Contradiction:
Improvemaintenance accessVSAvoidsafety during maintenance
Core Design Contradiction:
Ease of repairVSObject-affected harmful factors

Solution Approach 1:

The patent segments the device body into distinct functional zones with the power source (containing the fan) positioned in the horizontal direction away from the cleaning base. This spatial segmentation allows maintenance personnel to access the cleaning base components without being in proximity to the exposed fan, thereby reducing accidental contact risk while maintaining ease of repair for cleaning components.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If all liquid outlets have the same caliber, then manufacturing is simpler, but cleaning liquid distribution uniformity deteriorates

Engineering Contradiction:
Improveliquid outlet consistencyVSAvoidliquid distribution uniformity
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent implements local quality variation by designing liquid outlets with different calibers based on their specific functional requirements. Different sections of the liquid distribution system have outlets tailored to local needs, ensuring uniform cleaning liquid distribution across the cleaning surface while maintaining manufacturing feasibility through a standardized design approach.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The solution improves the safety and operability of the cleaning device by preventing accidental contact with the fan during maintenance and ensures efficient cleaning by uniformly distributing the cleaning liquid across the surface.

Implementation Method 1

a power source assembled on another side of the device body... a first air duct communicating the wastewater tank to an air inlet of the power source; and a second air duct communicating an air outlet of the power source to an air outlet of the cleaning device

AI summary

A cleaning device (20) and a cleaning system (100). The cleaning device (20) comprises a cleaning base (21) and a device body (22) pivotally connected to the cleaning base (21). The device body (22) further comprises: a wastewater tank (25) detachably assembled on one side of the device body (22); a power source (273) assembled on the other side of the device body (22); a first air duct (241) connecting the wastewater tank (25) and an air inlet (2731) of the power source (273) in a bending manner; and a second air duct (242) connecting an air outlet (2732) of the power source (273) and an air outlet (221) of the cleaning device (20). When the power source (273) is turned on, a working airflow flows through the cleaning base (21), the wastewater tank (25), and the first air duct (241) into the power source (273), and flows through the air outlet (2732) of the power source (273), the second air duct (242), and the air outlet (221) of the cleaning device (20) to be discharged.
