Solution Overview

Problem

There is a need to effectively neutralize microbial and viral contaminants and malodor in enclosed spaces such as vehicle cabins, hotel rooms, and other living spaces, as existing methods fail to adequately eliminate contaminants from textured surfaces and may not address airborne transmission, while also considering the potential for component corrosion from gaseous cleaning agents.

Innovation Solution

An apparatus using an aerator to agitate water and release a gaseous cleaning agent, protected by a corrosion-resistant shield, distributes the agent throughout the space to neutralize contaminants and malodor, with a digital controller and air distributor enhancing agitation and control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a gaseous cleaning agent is used to neutralize contaminants and malodor in enclosed spaces, then the effectiveness of contaminant removal is improved, but corrosion of apparatus components occurs

Engineering Contradiction:

Improvecontaminant neutralization effectivenessVSAvoidcomponent corrosion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The apparatus separates the gaseous cleaning agent generation chamber from the component housing through a shield structure. The shield divides the internal space into a treatment zone where the gaseous agent acts on contaminants and a protected zone where electronic components are shielded from direct exposure to corrosive gases.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A corrosion-resistant shield acts as an intermediary barrier between the gaseous cleaning agent and the apparatus components. This shield material selectively allows the gaseous agent to function in the treatment space while preventing direct contact with sensitive components, thereby mediating between the cleaning function and component protection.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If water is agitated to release gaseous cleaning agent, then the dispersal efficiency is improved, but energy consumption increases

Engineering Contradiction:

Improvegaseous agent dispersal efficiencyVSAvoidaerator energy consumption

Core Design Contradiction:

ProductivityVSUse of energy by moving object

Solution Approach 1:

The apparatus utilizes phase transition of water (liquid to vapor) enhanced by aeration. The aerator introduces air bubbles that agitate the water and promote evaporation, facilitating the release of gaseous cleaning agent from liquid solution into the vapor phase, thereby improving dispersal efficiency.

Inventive Principle:

Principle #36Phase transitions

Solution Approach 2:

The aerator employs pneumatic principles to generate air bubbles that rise through the water, creating agitation and increasing the surface area for gas release. This hydraulic-pneumatic interaction enhances the mass transfer from liquid to gas phase without requiring excessive mechanical energy input.

Inventive Principle:

Principle #29Pneumatics and hydraulics

3Duration of action of moving object

If the aerator continuously agitates water, then the gaseous cleaning agent is consistently released, but operational time is extended

Engineering Contradiction:

Improvegaseous agent release consistencyVSAvoidapparatus operational time

Core Design Contradiction:

Duration of action of moving objectVSLoss of time

Solution Approach 1:

The aerator operates in periodic cycles rather than continuously, alternating between agitation phases that release gaseous cleaning agent and rest phases that conserve energy. This periodic operation maintains consistent contaminant neutralization effectiveness while reducing overall operational time and energy consumption.

Inventive Principle:

Principle #19Periodic action

AI summary

The present technology presents an apparatus for cleaning the air and surfaces within an enclosed space of a viral, microbial, or malodor contamination. In an exemplary embodiment, the apparatus includes: a container configured to contain a water and a solid or gel pack that releases the gaseous cleaning agent upon contact with the water; an aerator housed in the base of the container; an air distributor in the container configured to distribute air from the aerator into the container to cause agitation of the water and release of gaseous agent; and a lid on the container having an opening configured to accelerate an air-borne spray of gaseous agent and water droplets therethrough into the surroundings.
