Solution Overview

Problem

Cleaning appliances often require excessive amounts of cleaning solution, leading to prolonged drying times and surface unusability, which is inefficient for surfaces that do not need deep cleaning.

Innovation Solution

An attachment tool for cleaning appliances that includes a housing with a suction nozzle, a fluid delivery circuit, and a bristle block with bristle clusters to distribute and recover cleaning solution efficiently, minimizing usage and drying time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If large amounts of cleaning solution are deposited directly on the surface, then deep cleaning effectiveness is improved, but the surface remains damp and unusable for significant periods

Engineering Contradiction:
Improvedeep cleaning effectivenessVSAvoiddrying time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The cleaning solution application is segmented into multiple controlled streams through multiple nozzles rather than one large application, allowing distributed coverage with minimal moisture at each location

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cleaning solution is applied locally through positioned nozzles that deliver solution only where needed on the surface, rather than uniformly across the entire surface, reducing overall moisture exposure time

Inventive Principle:
Principle #3Local quality

2Reliability

If large amounts of cleaning solution are used for deep cleaning, then cleaning effectiveness is improved, but solution usage efficiency deteriorates for surfaces that do not require deep cleaning

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidcleaning solution usage
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The cleaning system dynamically adapts solution application by using multiple controllable nozzles that can be selectively activated based on the specific cleaning needs of different surface areas, optimizing solution usage rather than applying maximum amount uniformly

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different regions of the surface receive cleaning solution only when and where needed through positioned nozzles, allowing localized treatment that matches actual contamination levels rather than uniform heavy application

Inventive Principle:
Principle #3Local quality

3Reliability

If cleaning solution is applied to the surface, then cleaning function is achieved, but the surface becomes damp and unusable

Engineering Contradiction:
Improvecleaning functionVSAvoidsurface usability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cleaning function is achieved through multiple small localized application points rather than one large wet area, allowing the surface to remain usable between treatment zones and reduce overall downtime

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The multiple nozzles enable rapid sequential treatment of different surface areas, allowing the cleaning process to move quickly through zones so that previously treated areas can return to service faster

Inventive Principle:
Principle #21Skipping (Rushing through)

Applied Scientific Principles
