Solution Overview

Problem

Existing mop cleaning devices are structurally complex and lack efficient separation of clear water from wastewater, making it difficult to wash the mop head effectively.

Innovation Solution

A mop cleaning device comprising a rotary mop, a bucket, a clear water container, and a valve for controlling water outflow, where the rotary mop can rotate within the bucket and the clear water container supplies clear water to the mop head, allowing for efficient separation of clear water from wastewater.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a pump is used to extract clear water for cleaning the mop head, then clear water can be supplied to the mop head, but the device structure becomes complicated and on-off control of water source is not available

Engineering Contradiction:
Improveon-off control of water sourceVSAvoiddevice structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The invention extracts the water supply function from a complex pump-based system and implements it through a simple gravity-fed structure. The clear water container is positioned above the mop head with a water outlet that allows water to flow down naturally, eliminating the need for a pump and providing simple on-off control through a valve.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system uses gravity to automatically supply water from the clear water container to the mop head without requiring external power or complex control mechanisms. The high position of the clear water container creates natural water flow, making the system self-service and simplifying the overall structure.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If clear water and wastewater are not separated, then the bucket size can be smaller, but the mop head cannot be washed with clear water each time

Engineering Contradiction:
Improvemop head washing qualityVSAvoidbucket size
Core Design Contradiction:
Ease of operationVSVolume of stationary object

Solution Approach 1:

The invention segments the water management system into separate clear water and wastewater streams. The clear water container is positioned independently above the bucket, allowing clear water to flow to the mop head separately from the wastewater collection area in the bucket. This segmentation enables repeated use of clear water for washing while maintaining a compact bucket design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention adds a vertical dimension to the water management system by positioning the clear water container above the bucket. This vertical arrangement allows clear water to be supplied from above while wastewater is collected in the bucket below, achieving separation without requiring a larger horizontal space.

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

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 device allows for effective separation of clear water from wastewater, enabling the mop head to be washed with clear water each time, while also reducing the size of the bucket due to the foldable mop design.

Implementation Method 1

the liquid level in the clear water container is higher than the clear water outlet so that clear water can flow to the mop head from the clear water container

Methodology Applied
Scientific EffectGravity: Gravitation
