Solution Overview

Problem

Existing mop buckets for flat mops are either complex, costly, or require strenuous manual operation, failing to integrate effective cleaning and squeezing functions efficiently.

Innovation Solution

A mop bucket with a bucket body featuring separate cleaning and squeezing sections, equipped with a squeezing device that presses against the mop head to clean and wring the wiper, utilizing various squeezer types and mechanisms to facilitate easy, labor-saving operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a foot-operated squeezing device with a squeezing basket and pedal is used, then squeezing function is achieved, but the structure becomes complicated and cost increases

Engineering Contradiction:
Improvesqueezing operation convenienceVSAvoidsqueezing device structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the squeezing function from the complex foot-operated pedal mechanism and implements it through a simple horizontal insertion motion of the mop head into the squeezing cavity. The squeezing board directly presses the mop fabric against the cavity wall without requiring pedals, levers, or complex linkages, thereby achieving squeezing with minimal structural complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of using a vertical pedal mechanism that requires downward foot pressure, the patent inverts the squeezing action to a horizontal insertion motion where the mop head is simply pushed into the squeezing cavity. This inversion simplifies the operational mechanism from a complex lever system to a direct linear motion.

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

2Ease of operation

If a hand-operated rotary mop rod with centrifugal rotation is used, then squeezing function is achieved, but the mop plate structure becomes complicated and cost increases

Engineering Contradiction:
Improvesqueezing operation convenienceVSAvoidmop plate structure
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The patent removes the requirement for a bendable mop plate structure and centrifugal rotation mechanism. Instead, the squeezing function is achieved by the fixed squeezing board pressing the mop fabric against the stationary cavity wall through horizontal insertion, eliminating the need for complex rotating or bendable components.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mop head itself performs the squeezing action through its own insertion motion into the cavity. The user simply pushes the mop head horizontally into the squeezing cavity, and the fixed squeezing board automatically presses the fabric against the wall, eliminating the need for separate rotary mechanisms or hand-cranking devices.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If manual pushing and squeezing with a squeezing mechanism on the mop rod is used, then squeezing function is achieved, but the operation becomes strenuous and user experience deteriorates

Engineering Contradiction:
Improvesqueezing operation convenienceVSAvoidmanual effort required
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent extracts the squeezing function from the mop rod itself and relocates it to a dedicated stationary squeezing cavity in the bucket. The squeezing board in the cavity performs the pressing action against the mop fabric, eliminating the need for the user to manually push or pull a squeezing mechanism attached to the mop rod.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mop head automatically engages with the squeezing board through horizontal insertion into the cavity. The user simply inserts the mop head and the fixed squeezing board automatically presses the fabric against the cavity wall, eliminating strenuous manual pushing or pulling actions and reducing energy expenditure.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If the mop fabric is detached and placed into a squeezing space before squeezing, then squeezing function is achieved, but the operation becomes inconvenient and time-consuming

Engineering Contradiction:
Improvesqueezing operation convenienceVSAvoidsqueezing operation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent merges the cleaning and squeezing functions into a single integrated operation. The mop head with the mop fabric remains attached to the mop rod throughout the process, and both cleaning and squeezing are achieved through continuous horizontal motion of the same mop head within the bucket, eliminating the need to detach and reattach the fabric.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The squeezing action is performed continuously as the mop head is inserted horizontally into the squeezing cavity without interruption. The mop fabric remains attached to the mop rod throughout the entire process, maintaining continuous useful action from cleaning to squeezing without requiring detachment or repositioning steps.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A mop bucket for cleaning and squeezing a flat mop includes a bucket body and a squeezing device disposed inside the bucket body; the bucket body has a squeezing water section and a cleaning section, which are respectively at two different positions when used; when the mop head of the flat mop is removably inserted into the squeezing device, the squeezing device presses against the wiper on the mop head and scrapes the wiper on the mop head. A cleaning tool set is further provided. The mop bucket can clean and squeeze a wiper on the flat mop by integrating both functions of cleaning and squeezing together, provide better cleaning and squeezing effects, and realize a convenient and labor-saving squeezing operation and pleasurable user experience.
