Solution Overview

Problem

Mops often require additional scrubbing force to effectively clean soiled surfaces, and hard-to-reach areas pose challenges due to the lack of suitable cleaning tools for these areas.

Innovation Solution

A mop assembly with a handle, wringing mechanism, and a removable secondary cleaning member, such as a scrubbing brush, which can be easily attached and detached for enhanced cleaning capabilities in difficult-to-reach areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a traditional mop is used for cleaning, then it can clean surfaces, but it lacks sufficient scrubbing force for soiled surfaces and cannot reach hard-to-access areas

Engineering Contradiction:
Improvecleaning capabilityVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cleaning system is divided into a primary cleaning member (mop head) and a removable secondary cleaning member (scrubbing brush). The secondary cleaning member can be detached and attached as needed, providing additional scrubbing functionality without permanently complicating the basic mop structure. This segmentation allows the system to adapt to different cleaning needs while maintaining simplicity when the secondary member is not required.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mop assembly is designed to perform multiple functions: it can operate as a standard mop for general surface cleaning, and when the secondary cleaning member is attached, it provides enhanced scrubbing capability for soiled surfaces and hard-to-reach areas. The connecting member with receiver and engaging features enables this multi-functionality by allowing easy attachment and detachment of the secondary cleaning member.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Force

If a scrubbing brush is permanently integrated into the mop, then scrubbing force is always available, but the device complexity increases and accessibility to hard-to-reach areas is reduced

Engineering Contradiction:
Improvescrubbing forceVSAvoidstructure
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The connection between the primary and secondary cleaning members is designed to be dynamic rather than fixed. The engaging member with slot and retention features allows the secondary cleaning member to be attached when scrubbing force is needed and detached when it is not required or when accessing hard-to-reach areas. This dynamic configuration optimizes both scrubbing capability and accessibility.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a removable secondary cleaning member is added to the mop, then versatility is improved, but the ease of operation decreases due to attachment and detachment steps

Engineering Contradiction:
Improvecleaning optionsVSAvoidattachment process
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The connecting member serves as an intermediary structure that facilitates easy attachment and detachment of the secondary cleaning member. The receiver with engaging member and slot provides a simple mechanical interface, while the retention member secures the connection. This intermediary design allows quick changes between cleaning modes without complex procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Aspects described herein generally relate to a cleaning system, such as a cleaning implement with a primary cleaning member and a removable secondary cleaning member, in particular a mop assembly with a primary cleaning member and a removable secondary cleaning member. The primary cleaning member may be a sponge based cleaning member and the secondary cleaning member may be a scrubbing brush or similar handheld scrubbing member. The scrubbing brush may have an attachment member that includes a pair of rails and a tab assembly that helps to releasably connect the scrubbing brush to a connecting member of the mop assembly.
