Solution Overview

Problem

Traditional mop buckets have limited cleaning effectiveness and result in significant water waste due to inefficient water utilization and secondary pollution from dirty water, necessitating frequent water changes.

Innovation Solution

A water-saving mop bucket design featuring an outer bucket, inner bucket, cover plate assembly, and pedal mechanism, with a rotating head and water outlet valve, allowing for efficient water distribution and separation of clean and dirty water, and incorporating a cleaning brush block for enhanced mop cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional mop buckets use simple immersion cleaning, then the device complexity is low, but the cleaning effect is limited and water resources are wasted

Engineering Contradiction:
Improvedevice complexityVSAvoidcleaning effect
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The mop bucket is divided into separate functional zones: a cleaning area with water spray nozzles and a squeezing area separated by a partition plate. This segmentation allows different cleaning operations to occur simultaneously in different regions, improving overall cleaning effectiveness without significantly increasing device complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A water spray nozzle system is introduced as an intermediary element to deliver clean water to the mop during cleaning. The nozzles are positioned to spray water directly onto the mop head, enhancing the cleaning effect while maintaining relatively simple device structure

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If traditional mop buckets allow water to flow freely, then the ease of operation is high, but water resources are wasted due to ineffective utilization

Engineering Contradiction:
Improveease of operationVSAvoidwater waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The partition plate extracts and separates the water flow path into distinct zones. Clean water is directed to the cleaning area through nozzles, while dirty water is channeled to the squeezing area. This separation ensures that clean water is used effectively for cleaning before being disposed of, reducing water waste while maintaining ease of operation

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Clean water is sprayed onto the mop head in advance during the cleaning phase before the mop is squeezed. This preliminary application of clean water ensures thorough wetting and cleaning of the mop, maximizing the utility of each unit of water before it becomes dirty and is discarded

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If mop buckets lack dedicated cleaning structures, then the device complexity is low, but secondary pollution occurs reducing mop cleaning ability

Engineering Contradiction:
Improvestructure complexityVSAvoidsecondary pollution
Core Design Contradiction:
Device complexityVSObject-generated harmful factors

Solution Approach 1:

The partition plate divides the bucket interior into a cleaning area where clean water is sprayed and a squeezing area where dirty water collects. This segmentation prevents dirty water from coming into contact with the mop during the cleaning phase, eliminating secondary pollution while adding minimal structural complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The partition plate acts as an intermediary barrier between clean and dirty water zones. It physically separates the two water streams, preventing contaminated water from re-contaminating the mop head during cleaning operations, thus eliminating secondary pollution with a simple structural addition

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A water-saving mop bucket includes an outer bucket, an inner bucket, a cover plate assembly and a pedal mechanism. The cover plate assembly is detachably fit in the middle of the inner bucket. The pedal mechanism is installed at the lower part of the outer bucket and extends upward through the inner bucket, and is detachably connected with the cover plate assembly. The water spraying structure is arranged in the center, and the sprayed water can flow from the inside to the outside under the centrifugal force, so that the entire mop can be washed, and all the sprayed water can be effectively utilized, thus achieving water saving; meanwhile, the functions of cleaning and dehydration are realized.
