Solution Overview

Problem

Conventional toilet cleaning tools, such as brushes and pressurized washers, are inefficient and unsanitary due to the need for manual scrubbing, storage of contaminated brushes, and exposure to splashback, which can be physically demanding and unsanitary for users.

Innovation Solution

A handheld liquid dispensing wand with a splash guard that creates a pressurized stream of water for cleaning, attached to a base station with a liquid basin, allowing for easy storage and protection from overspray, and optional disposable or reusable splash guards for hygiene.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a pressurized washer is used to clean toilet surfaces, then cleaning efficiency is improved, but user exposure to contaminated water and waste material splashing occurs

Engineering Contradiction:
Improvecleaning efficiencyVSAvoiduser exposure to contaminants
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

A shield or barrier is introduced as an intermediary component between the pressurized washer and the user, blocking the path of contaminated spray and preventing direct exposure while allowing the cleaning function to continue

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The harmful spray is extracted or redirected away from the user by using a shield that deflects the contaminated water and waste material in a different direction, separating the cleaning action from the user

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If a conventional toilet brush is used, then storage is simple, but the brush becomes unsanitary due to retained waste material

Engineering Contradiction:
Improvestorage simplicityVSAvoidsanitary condition
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The brush head or entire brush is designed as a disposable component that is replaced after a single use or after contact with contaminants, eliminating the sanitation problem while maintaining simple storage for the handle

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The brush is divided into separable components (handle and brush head), allowing the contaminated brush head to be discarded while the handle remains for storage and potential reuse with a new brush head

Inventive Principle:
Principle #1Segmentation

3Reliability

If manual scrubbing is used to remove stains, then cleaning effectiveness is achieved, but physical strain on the user increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidphysical strain
Core Design Contradiction:
ReliabilityVSForce

Solution Approach 1:

Manual mechanical scrubbing is replaced with a pressurized liquid jet system that uses hydraulic pressure instead of human muscular force to achieve the cleaning effect, eliminating physical strain while maintaining cleaning effectiveness

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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 system provides a convenient, sanitary, and efficient cleaning method that reduces physical strain and prevents user exposure to contaminants, with the splash guard ensuring protection from splashback and easy device maintenance.

Implementation Method 1

The handheld liquid dispensing wand includes a nozzle configured to create a pressurized stream of water

Methodology Applied
Scientific EffectPressurized liquid stream: Pressure Gradient

Implementation Method 2

capable of producing a high pressure stream of liquid to clean contaminants from surfaces while protecting a user operating the wand from spray reflected back toward the wand from the surfaces

Methodology Applied
Scientific EffectSpray reflection: Reflection

AI summary

A cleaning system for generating a liquid jet via a liquid dispensing wand, includes an elongate tube having a first end and a second end. A nozzle is disposed at the second end of the elongate tube. A splash guard is slidably coupled with the elongate tube, and is slidable longitudinally between the first end and the second end of the elongate tube. A basin is configured to hold a liquid. A conduit fluidly couples the basin to the liquid dispensing wand. A mount removably stores the liquid dispensing wand when not in use. With the splash guard disposed proximal the second end and the nozzle, placement of the liquid dispensing wand into the mount for storing causes the splash guard to slide from the second end to the first end of the elongate tube.
