Solution Overview

Problem

Existing surface cleaning technologies face issues with dripping or misting due to the use of pumps or gravity systems, which either lack sufficient fluid volume and energy for effective debris removal or fail to contain the cleaning fluid and debris within the cleaning apparatus.

Innovation Solution

A vacuum-powered surface cleaning device that encloses the surface to be cleaned, using compressed air to create a partial vacuum, allowing high-flow cleaning fluid circulation without external pumping, and automatically stops fluid flow when the surface is removed, preventing dripping or misting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If pumps or pressure devices are used to induce cleaning fluid flow, then cleaning fluid can be delivered to the surface, but dripping or misting occurs outside the cleaning apparatus

Engineering Contradiction:
Improvecleaning fluid flow volumeVSAvoiddripping or misting
Core Design Contradiction:
Quantity of substanceVSObject-generated harmful factors

Solution Approach 1:

Instead of using positive pressure devices (pumps) to force fluid through the system, the invention inverts the approach by using a vacuum chamber to suction fluid through the cleaning surface. This reversal of pressure direction prevents fluid from escaping and dripping or misting outside the apparatus, while still achieving high flow rates for aggressive cleaning

Inventive Principle:
Principle #13The other way round (Inversion)

2Use of energy by moving object

If low flow pumping systems are used, then energy consumption is reduced, but insufficient cleaning fluid volume and energy are introduced to flush debris from the surface

Engineering Contradiction:
Improveenergy consumptionVSAvoiddebris removal effectiveness
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The invention employs pneumatic principles by using a vacuum chamber created through compressed air injection into a venturi structure. This pneumatic system generates high-velocity fluid flow and strong suction force without requiring high-power mechanical pumps, achieving both energy efficiency and high productivity for effective debris removal

Inventive Principle:
Principle #29Pneumatics and hydraulics

3Device complexity

If gravity cleaning systems are used, then device complexity is reduced, but expended cleaning fluid and debris are not adequately removed from the surface

Engineering Contradiction:
Improvesystem structureVSAvoidfluid and debris removal
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system uses the cleaning fluid itself to generate the vacuum force needed for removal. Compressed air injected into the venturi structure uses the kinetic energy of the fluid flow to create suction, eliminating the need for separate vacuum pumps or complex mechanical systems while maintaining high removal effectiveness

Inventive Principle:
Principle #25Self-service

AI summary

A vacuum powered surface cleaning apparatus which is capable of cleaning an adjacent surface to remove debris without external leaking, dripping or misting. The vacuum powered surface cleaning apparatus includes an eductor assembly to create a vacuum within the device to naturally induce a flow of cleaning fluid which is imparted onto the adjacent surface to be cleaned. The expended cleaning fluid and debris are expelled from the apparatus through the eductor to external atmosphere or to an external waste or recycling container. Removal of the adjacent surface opens the internal chamber which causes a loss of partial vacuum which ceases flow of cleaning fluid, thereby eliminating the possibility of external dripping or misting.
