Solution Overview

Problem

Existing handheld brushes for cleaning footwear require separate application and reapplication of cleaning fluid, leading to inefficiency and increased components, making them cumbersome for use, especially in outdoor settings where a compact and intuitive cleaning solution is needed.

Innovation Solution

A single handheld brush design with a built-in fluid dispensing system, featuring a valve and scraper, allows controlled expulsion of fluid through a flow path between the brush base and aperture, minimizing fluid loss and requiring fewer components, while the ergonomic design facilitates intuitive handling and efficient cleaning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate pieces of equipment (brush, fluid container, scraper) are used for cleaning footwear, then the cleaning function is comprehensive, but the device complexity and number of components increases

Engineering Contradiction:
Improvecleaning function comprehensivenessVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate cleaning tools (brush, fluid container, scraper) into a single integrated handheld device. The brush head incorporates a fluid reservoir with dispensing apertures, and the handle integrates a scraper, allowing all cleaning functions to be performed with one compact tool rather than multiple separate pieces of equipment.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The handheld brush is designed to perform multiple cleaning functions simultaneously: applying cleaning fluid through dispensing apertures, scrubbing with bristles, and scraping excess dirt with the integrated scraper. This multi-functional design eliminates the need for separate specialized tools while maintaining comprehensive cleaning capability.

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

2Productivity

If cleaning fluid is applied manually before using the brush, then the brush can clean effectively, but the time required for cleaning increases due to repeated fluid application

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidtime for fluid application
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The cleaning fluid is pre-loaded into the reservoir within the brush head before use. The fluid is automatically dispensed through apertures in the brush head during cleaning, eliminating the need for separate pre-application and reapplication steps. This preliminary preparation of fluid delivery integrates the fluid application function directly into the brushing action.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The fluid dispensing system provides continuous fluid delivery to the brush bristles during the cleaning process. As the user brushes, fluid is continuously supplied through the apertures, maintaining optimal cleaning conditions throughout the operation without interruption for reapplication, thereby sustaining productive cleaning action continuously.

Inventive Principle:
Principle #20Continuity of useful action

3Ease of manufacture

If manual fluid application is used, then fluid can be applied to the brush, but the economy of operation decreases due to inadequate or excessive fluid application

Engineering Contradiction:
Improvefluid application capabilityVSAvoidfluid economy
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The brush head design incorporates apertures that regulate fluid delivery based on the cleaning action. The fluid dispensing rate is controlled by the design of the apertures and the pressure applied during brushing, providing automatic feedback control that prevents both inadequate and excessive fluid application, optimizing fluid economy without requiring manual adjustment.

Inventive Principle:
Principle #23Feedback

4Adaptability or versatility

If multiple pieces of equipment are carried for cleaning, then comprehensive cleaning can be performed, but the portability and convenience decrease especially during outings

Engineering Contradiction:
Improvecleaning capabilityVSAvoidportability
Core Design Contradiction:
Adaptability or versatilityVSWeight of moving object

Solution Approach 1:

The patent integrates the brush head, fluid reservoir, and scraper into a single handheld unit, replacing multiple separate pieces of equipment (brush, fluid container, scraper) with one compact tool. This merging significantly reduces the total weight and bulk of cleaning equipment that must be carried during outings while maintaining all necessary cleaning functions.

Inventive Principle:
Principle #5Merging (Combining)

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

The solution provides effective and efficient cleaning of footwear with controlled fluid application, reducing the risk of spillage and excess fluid use, and allows for easy handling by both adults and children, making it suitable for various environments, including sports settings.

Implementation Method 1

a portion of the body which is resiliently deformable so that, in use, squeezing of this portion forces the contained fluid along the flow path such that it may exit the aperture

Methodology Applied
Scientific EffectPressure increase: Pressure Increase

Implementation Method 2

a valve which is located adjacent the first end of the body and which controls the flow of the cleaning fluid through the body

Methodology Applied
Scientific EffectValve closure: Valve

AI summary

A single handheld brush comprises a body, the body being elongate and comprising first and second ends and an interior, the interior comprising a cavity, wherein, in use, fluid may be stored; the first end comprising a brush head, and wherein the brush head is mounted on a brush base portion, the brush base portion having a first face and a second face and a passage, the passage running through the brush base portion and being open at both ends; the second end comprising a scraping tool; the brush further comprising a flow path running from the cavity, to an aperture in the brush base portion, such that fluid in the cavity may flow along the flow path and be expelled from the aperture, and a valve closure located adjacent the first end, wherein the valve may be moved from an open position wherein the flow path is open, to a closed position wherein the flow path is shut and vice versa, such that the flow of fluid through the aperture may be regulated.
