Solution Overview
Problem
Existing ozone gas generating devices lack efficient control mechanisms to safely achieve high ozone concentrations for microbial disinfection while ensuring human safety, as they often fail to differentiate between occupied and unoccupied spaces, leading to potential adverse effects on living beings.
Innovation Solution
The implementation of an ozone gas generating device with a dual operational mode, utilizing UV irradiation and a remote motion sensor to safely increase ozone production only when the space is unoccupied, coupled with an AI-driven network of ozone gas generating devices for real-time concentration control, ensuring safe and effective ozone distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ozone gas generating devices operate at high concentration levels to achieve effective microbial disinfection, then the anti-viral and anti-microbial effectiveness is improved, but the safety risk to living beings deteriorates
Solution Approach 1:
The system dynamically adjusts ozone generation between two modes: a first mode generating lower concentrations for safety during occupied periods, and a second mode generating higher concentrations for effective disinfection during unoccupied periods. This dynamic switching resolves the contradiction by adapting ozone levels to real-time occupancy conditions.
Solution Approach 2:
The motion sensor detects occupancy status in advance before ozone generation begins or increases. The system preliminarily determines whether the space is occupied and accordingly prevents high-concentration ozone generation when occupants are present, eliminating the safety risk before it can occur.
2Productivity
If ozone gas generating devices increase ozone production rate to achieve high concentrations quickly, then the disinfection efficiency is improved, but the safety control difficulty increases
Solution Approach 1:
The system incorporates feedback from motion sensors to continuously monitor occupancy status and automatically adjusts ozone generation levels. When motion is detected indicating occupancy, the system reduces or stops high-concentration generation; when no motion is detected, it can safely operate at high rates. This feedback loop maintains safety while enabling high productivity when appropriate.
Solution Approach 2:
The motion sensor acts as an intermediary between occupancy detection and ozone generation control. It provides the critical information needed to mediate between the desire for high production rates and the need for safety control, enabling the system to switch between operational modes based on real-time conditions.
3Device complexity
If a single ozone gas generating device operates independently, then the device simplicity is maintained, but the ability to achieve uniform ozone distribution across multiple spaces deteriorates
Solution Approach 1:
Multiple ozone gas generating devices are merged into a coordinated network that operates as a unified system. Each device independently detects its local occupancy status and autonomously adjusts its operation, yet collectively they achieve uniform ozone distribution across multiple spaces through parallel operation rather than requiring complex centralized control.

AI summary
A method and system of controlling a cohort of ozone gas generating devices. The method comprises identifying, at a computing device, a plurality of ozone gas generating devices that constitute the cohort, detecting, via at least one remote ozone gas sensor device located in a spatial area associated with the cohort in conjunction with one or more processors of the computing device, a concentration of ozone gas constituent of ambient air within the spatial area, and instructing, responsive to detecting the concentration of the ozone gas constituent as being one of above and below a predetermined threshold concentration, at least one ozone gas generating device of the cohort to perform one of increasing and decreasing a rate of ozone gas generation associated therewith.
