Solution Overview

Problem

Existing flat mops require manual detachment and reattachment of soiled and clean mopping layers, posing hygiene and chemical exposure risks, and inefficiently manage the replacement process.

Innovation Solution

A flat mop design featuring a pivot mechanism with movable side wings and a latching mechanism that allows for hands-free detachment and attachment of mopping layers, using an actuation member to fold the wings and release the old layer or attach a new one without direct user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If manual detachment and reattachment of mopping layers is used, then the structure is simple, but hygiene risks and chemical exposure increase

Engineering Contradiction:
Improvestructural simplicityVSAvoidhygiene risks and chemical exposure
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary mechanism (the automated latching system with movable wings and release members) that mediates between the user and the mopping layer. The user operates the actuation member rather than directly handling the mopping layer, and the mechanism automatically performs the attachment/detachment function, thus eliminating direct contact with harmful substances while maintaining structural feasibility

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The latching mechanism is designed to perform the attachment and detachment operations automatically once triggered by the actuation member. The movable wings self-adjust to engage or disengage the mopping layer without requiring manual manipulation, making the system serve itself rather than requiring continuous user intervention for each operation

Inventive Principle:
Principle #25Self-service

2Object-affected harmful factors

If automated latching mechanism with movable wings is used, then hygiene and chemical exposure are reduced, but device complexity increases

Engineering Contradiction:
Improvehygiene risks and chemical exposureVSAvoidmechanism complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The complex latching function is segmented into distinct functional components: the movable wings that provide the mechanical action, the release members that control the locking state, and the actuation member that triggers the sequence. This segmentation allows each component to be simple in itself while collectively achieving the automated function, reducing overall complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mechanism uses movable wings that can dynamically change position between locked and unlocked states. This dynamic capability allows the same structural elements to serve multiple functions (locking during operation, opening during replacement) without requiring separate mechanisms for each state, thereby reducing complexity while maintaining hygiene benefits

Inventive Principle:
Principle #15Dynamics

3Reliability

If side wings are held in horizontal orientation by latching mechanism, then mopping layer retention is secure, but detachment requires manual handling

Engineering Contradiction:
Improvemopping layer retentionVSAvoiddetachment operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The actuation member serves as an intermediary that triggers the release of the latching mechanism. Instead of requiring direct manual handling of the mopping layer for detachment, the user simply operates the actuation member, which then mediates the entire detachment process through the movable wings and release members, maintaining both security and ease of operation

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The invention concerns the field of floor mops and in particular flat mops for mopping floor surfaces and which have detachable absorbent mopping layers and addresses problems of contamination and handling of mopping layers. In accordance with the invention there is provided a flat mop (11) comprising an elongate handle portion (14) attached to a flat mop head, the mop head comprising a generally central base plate (12), an upper side of the base plate being attached to a handle mount via a pivot mechanism (13), wherein the base plate is disposed between two horizontally extending co-planar side wings (21,22) to which a detachable mopping layer may be attached, wherein the side wings are movable one with respect to the other so as to articulate between the co-planar operative horizontal orientation in which they align with each other so as to retain a mopping layer extended between opposite ends of the wings and a folded orientation in which one wing is angled with respect to the other so that the separation between wing opposite ends is reduced thereby facilitating the detachment of the mopping layer or attachment of a new mopping layer, wherein the base plate includes a wing latching mechanism which holds the side wings in the horizontal orientation, but which includes at least one movable release member (23, 24) which may be displaced to permit the wings to adopt the folded orientation, and characterised in that a handle mount (15) comprises an actuation member (16) which is movable to approach the base plate to directly or indirectly displace the release member (23, 24) and permit folding of the side wings.
