Solution Overview

Problem

Existing ozone sanitizing devices are inefficient in quickly reducing ozone concentration in closed environments, often requiring long ventilation times and being ineffective in spaces with limited ventilation systems, posing health risks.

Innovation Solution

A device with integrated ozone sanitizing and deozonization means, utilizing a fluid-operated sanitizing circuit with a fan for ozone release and a deozonization circuit with a filtering fluid to rapidly sanitize and reduce ozone levels, featuring a control system for automated operation and ozone sensors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ozone is released into the environment for disinfection, then antiviral and antibacterial action is achieved, but high concentration of ozone remains in the air causing harmful effects on human health

Engineering Contradiction:
Improvedisinfection effectivenessVSAvoidharmful effects on human health
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A deozonization circuit is introduced as an intermediary system between the ozone sanitizing circuit and the environment. This circuit uses a filtering fluid (such as water or water-based solutions) to chemically absorb and remove excess ozone from the air through contact in a deozonization chamber, converting harmful ozone into harmless substances before air is released back into the environment.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system discards excess ozone from the sanitized air by passing it through the deozonization circuit where it is absorbed by the filtering fluid. The filtering fluid can be periodically replaced or regenerated, allowing continuous operation of the ozone sanitizing system without accumulating harmful ozone levels in the environment.

Inventive Principle:
Principle #34Discarding and recovering

2Object-affected harmful factors

If ventilation is used to reduce ozone concentration, then harmful effects are reduced, but extremely long resting time is required and ventilation may not be effective in spaces with limited windows or ventilation systems

Engineering Contradiction:
Improveozone concentration in airVSAvoidresting time for ventilation
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent replaces the mechanical ventilation system (which requires physical airflow through windows or ventilation ducts) with a chemical deozonization system. The deozonization circuit uses chemical absorption through filtering fluid to remove ozone directly from the air, eliminating the need for prolonged mechanical ventilation and enabling effective ozone removal in sealed or poorly ventilated spaces.

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

3Productivity

If a deozonization circuit with filtering fluid is added to rapidly reduce ozone, then deozonization speed is improved, but device complexity increases

Engineering Contradiction:
Improvedeozonization speedVSAvoidcircuit complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The deozonization circuit is integrated with the ozone sanitizing circuit by sharing common components such as the pump, fluid conduits, and control system. The filtering fluid circulates through a separate chamber but uses the same hydraulic infrastructure, reducing the overall complexity increase despite adding the deozonization function.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The filtering fluid serves multiple functions: it deozonizes the air by chemical absorption, can be used to clean the interior surfaces of the device, and may provide additional disinfection properties. This multi-functionality justifies the added complexity by providing multiple benefits from a single system component.

Inventive Principle:
Principle #6Universality (Multi-functionality)
