Detachable Wringer Mop Bucket for Capacity and Stacking

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional mop buckets have limited liquid capacity due to the deep extension of the wringer into the basin and are difficult to stack, making them inefficient in terms of storage and transportation space.

Innovation Solution

A mop bucket design featuring a detachable wringer supported by a side extension that allows for increased liquid capacity and facilitates interlocking stacking, utilizing a cavity for the wringer and ribs for spacing control, along with mutually cooperating attachment means for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wringer extends deep into the basin, then the wringer is stable and functional, but the liquid capacity of the bucket is reduced

Engineering Contradiction:

Improvewringer stabilityVSAvoidliquid capacity

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

The wringer support structure is divided into two parts: a base portion integrated into the bucket and a separate wringer component that attaches to it. This segmentation allows the wringer to be positioned higher in the bucket, increasing liquid capacity while maintaining stability through the attached connection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The wringer support extends upward from the base in a vertical dimension, creating a elevated platform for the wringer. This dimensional change allows the wringer to be positioned higher without extending deep into the basin, thus increasing the liquid capacity while maintaining wringer stability through the vertical support structure.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If the wringer extends deep into the basin, then the wringer is stable, but stacking the buckets becomes difficult

Engineering Contradiction:

Improvewringer stabilityVSAvoidstacking ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The wringer support includes a cavity that receives a corresponding protrusion on another bucket when stacked. This nesting arrangement allows buckets to be stacked in a close interlocking relationship, making stacking easy while the wringer remains stable on its support structure.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The wringer is made detachable from the bucket, allowing it to be separated when stacking is required. This segmentation enables easy stacking of buckets without the wringer interfering, while the wringer can be reattached when needed for stable operation.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If the wringer is made detachable, then stacking and storage space are improved, but the complexity of the bucket structure increases

Engineering Contradiction:

Improvestacking easeVSAvoidbucket structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The wringer attachment mechanism is merged with the wringer support structure itself. The support includes integrated attachment means (clips and apertures) that combine the support function with the attachment function, reducing overall structural complexity while enabling detachability for easy stacking.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A mop bucket (100) having a side (104) and a detachable wringer (112). Part of the side extends into the bucket to form a support (108) for the detachable wringer (112). The side may be the base (102) of the bucket. The wringer support (108) may have a cavity (111) that is accessible from the side and which is shaped to receive a corresponding support on a corresponding bucket.
