Solution Overview

Problem

Existing flat mops are not cleaned properly during the cleaning process, leading to contamination of the mop head with sewage due to water overflow and poor drainage in the mop bucket.

Innovation Solution

A double-layer mop bucket design with separate clean water and sewage areas, a water supply component, and drainage ports to ensure cleanliness by guiding sewage away from the mop head during cleaning and scraping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the mop head is inserted into the inner bucket for cleaning, then the mop can be cleaned without touching the ground, but the mop head becomes contaminated with sewage when water flows into the inner bucket during scraping

Engineering Contradiction:
Improvemop cleaning convenienceVSAvoidmop head contamination
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The inner bucket is divided into two distinct areas: a clean water area for rinsing the mop head and a sewage area for collecting dirty water. This segmentation prevents contamination by ensuring that clean water and sewage remain separated throughout the cleaning process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sewage is extracted and isolated into a separate sewage area within the inner bucket, away from the clean water area. This extraction prevents the harmful factor (sewage) from contacting the mop head during the cleaning operation.

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If a single-bucket design is used, then the device complexity is reduced, but the mop head cannot be kept clean during the cleaning process

Engineering Contradiction:
Improvebucket structure simplicityVSAvoidmop head contamination
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The single bucket is segmented into functional zones (clean water area and sewage area) using internal structures such as baffle plates or raised boundaries. This allows the system to maintain cleanliness functionality without requiring completely separate buckets, thus balancing complexity and effectiveness.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If drainage ports are added to separate clean water and sewage, then sewage can be guided away from the mop head, but the device complexity increases

Engineering Contradiction:
Improvesewage contact preventionVSAvoiddrainage system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

A baffle plate or partition structure acts as an intermediary element that guides water flow from the clean water area to the sewage area through designated drainage ports. This intermediary structure simplifies the drainage system by providing a passive, gravity-driven flow path without requiring complex pumps or valves.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Stability of the object's composition

If the inner bucket is fixed in the outer bucket, then structural stability is improved, but the ease of cleaning and maintenance is reduced

Engineering Contradiction:
Improvebucket structure stabilityVSAvoidinner bucket removal
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The inner bucket is designed with dynamic positioning capabilities - it can be stably positioned during operation through guide rails or定位 structures, but can also be easily removed when needed by overcoming a small retention force. This dynamic design allows the system to switch between stability and ease of removal based on operational needs.

Inventive Principle:
Principle #15Dynamics
