Solution Overview

Problem

Existing air purification devices using UV radiation are limited in their ability to effectively purify large volumes of air and decontaminate surfaces at a distance, as they require direct proximity to the UV source and produce short-lived hydroxyls that are not effective beyond immediate adjacency.

Innovation Solution

A hydroxyl generator with multiple UV lamps arranged to create overlapping coronas that fill a housing, generating long-lasting hydroxyls capable of purifying air and decontaminating surfaces at distances up to 50 feet or more, using UV radiation with wavelengths of 185 nm and 254 nm, and incorporating a method to humidify air for enhanced hydroxyl production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If UV radiation sources are used to generate hydroxyls for air purification, then air cleansing capability is improved, but the effective range is limited to direct proximity of the UV sources

Engineering Contradiction:
Improveair purification capabilityVSAvoideffective range
Core Design Contradiction:
Object-affected harmful factorsVSLength of stationary object

Solution Approach 1:

The device segments the UV radiation function into multiple discrete UV lamps arranged in arrays, allowing the hydroxyl generation capability to be distributed across multiple points rather than concentrated at a single location, thereby extending the effective purification range

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces hydroxyls as an intermediary substance that is generated by UV radiation and then transported by air currents to decontaminate surfaces at a distance. The hydroxyls act as carriers of the purification function, extending the effective range beyond direct UV exposure zones

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If UV radiation is used to generate hydroxyls, then decontamination effectiveness is improved, but the hydroxyls are short-lived and cannot persist after the device is turned off

Engineering Contradiction:
Improvedecontamination effectivenessVSAvoidhydroxyl lifespan
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The device generates hydroxyls in advance and introduces them into the air stream before the air reaches the surfaces to be decontaminated. This preliminary generation allows the hydroxyls to be present and active during the air flow, extending their effective duration and range

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the parameters of hydroxyl generation by using specific UV wavelengths (185-254 nm) and controlling the concentration of water vapor in the air stream, thereby optimizing hydroxyl production and extending their lifespan and effectiveness

Inventive Principle:
Principle #35Parameter changes

3Quantity of substance

If multiple UV lamps are arranged to overlap coronas for maximum hydroxyl generation, then hydroxyl production is improved, but device complexity increases

Engineering Contradiction:
Improvehydroxyl concentrationVSAvoidlamp arrangement complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent merges multiple UV lamps into integrated arrays where the coronas overlap, combining their individual hydroxyl generation capabilities into a unified system that produces superior hydroxyls. This merging approach achieves high hydroxyl concentration while managing complexity through systematic arrangement

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 hydroxyl generator produces superior, long-lasting hydroxyls that can effectively decontaminate air and surfaces at significant distances and persist for several minutes after the device is turned off, demonstrating enhanced air purification and deodorization capabilities in large indoor settings.

Implementation Method 1

a plurality of UV lamps, each of which creates a corona when generating UV radiation

Methodology Applied
Scientific EffectUV radiation: Light

Implementation Method 2

each of which creates a corona when generating UV radiation, the corona having a radius

Methodology Applied
Scientific EffectCorona discharge: Corona Discharge

Implementation Method 3

hydroxyls are formed by the interaction of ultraviolet (UV) radiation and atmospheric water vapor: H2O+UV radiation H+OH

Methodology Applied
Scientific EffectPhotodissociation: Photodissociation

Implementation Method 4

Hydroxyls are very reactive, and therefore are usually short-lived, as they react with compounds around them. This reactivity makes hydroxyls excellent 'scavengers' for compounds which act as pollutants

Methodology Applied
Scientific EffectOxidation: Oxidation

AI summary

Superior hydroxyls are provided which have effects on organic and inorganic compounds and/or pollutants over substantial periods of time and/or at substantial distances from where the superior hydroxyls are generated. Also provided is a hydroxyl generator, in which UV lamps are positioned such that the coronas which they produce when emitting UV radiation fill substantially all the interior space of the hydroxyl generator. The coronas overlap each other by a maximum amount of between 5% and 25% of the radius of each corona.
