Solution Overview

Problem

Existing wiping mops require frequent exchange or external cleaning of the wiping element, which is inconvenient and inefficient for continuous use.

Innovation Solution

A compact wiping mop design with a housing containing a mechanical dirt separator, two tanks for wiping liquids, and a system for guiding the wiping band through the housing, allowing for continuous cleaning without manual exchange, using scraper pins to collect coarse particles and a dual-tank system to separate and clean the wiping band.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the wiping element is used continuously to clean surfaces, then cleaning productivity increases, but the wiping element becomes dirty and requires exchange or external cleaning

Engineering Contradiction:
Improvecontinuous cleaning capabilityVSAvoidwiping element cleanliness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The wiping mop is equipped with an integrated cleaning system that allows the wiping element to clean itself automatically during operation. The cleaning liquid reservoir and distribution system enable the wiping element to be rinsed and reused without external intervention, making the system self-sufficient for continuous operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system separates dirty cleaning liquid from the wiping element and recycles it through a filtration and reuse mechanism. The cleaning liquid is collected, filtered to remove captured dirt particles, and reapplied to the wiping element, enabling continuous recovery and reuse of both the wiping element and cleaning liquid.

Inventive Principle:
Principle #34Discarding and recovering

2Reliability

If the wiping element is frequently exchanged to maintain cleanliness, then cleaning quality is maintained, but time is lost and productivity decreases

Engineering Contradiction:
Improvewiping element cleanlinessVSAvoidcleaning efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The wiping element undergoes continuous cleaning action through the integrated rinsing system during the cleaning process. Rather than stopping to exchange elements, the system maintains continuous operation by automatically rinsing the wiping element with fresh cleaning liquid from the reservoir, ensuring uninterrupted cleaning productivity.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system prepares clean wiping liquid in advance within the integrated reservoir and positioning system. This preliminary preparation of cleaning liquid allows the wiping element to be quickly rinsed and recharged without interruption to the overall cleaning process, eliminating downtime associated with element exchange.

Inventive Principle:
Principle #10Preliminary action

3Volume of moving object

If a compact housing design is used, then device portability and space efficiency improve, but the internal space for cleaning mechanisms is reduced

Engineering Contradiction:
Improvehousing compactnessVSAvoidcleaning mechanism integration
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The cleaning mechanisms are nested within the compact housing structure. The cleaning liquid reservoir, distribution channels, and collection systems are integrated in a nested arrangement where components are housed within one another, maximizing space utilization while maintaining compact overall dimensions.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The cleaning mechanisms utilize vertical and three-dimensional space within the housing rather than only horizontal expansion. The reservoir and cleaning pathways are arranged in multiple levels and dimensions, allowing complex cleaning functions to be packed into a compact footprint by exploiting spatial dimensions efficiently.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables reliable and continuous cleaning of surfaces without the need for frequent wiping element exchange, maintaining a relatively clean wiping band through the use of a dual-tank system that separates and washes dirt particles, allowing for thorough and efficient cleaning of larger areas.

AI summary

The present invention relates to a wiping mop (10) with a housing (20), wherein an anchoring mechanism (11) for a handle (12) for guiding the wiping mop (10) is attached to the upper side of the housing. A wiping band (30) which is closed in itself is guided partially around and partially through the housing (20). On entry into the housing (20) the wiping band (30) runs through a mechanical dirt separator as well as a first (80) and a second (70) tank to be filled with wiping liquids in each case, whereby the wiping band (30) is cleaned of dirt particles taken up during use and is moistened for further wiping. Before leaving the second tank (80) the wiping band (30) is wrung out by cheeks of an outlet slot which are displaceable manually relative to one another.
