Solution Overview
Problem
Existing ozone generators struggle to efficiently and safely generate high concentrations of ozone gas in enclosed spaces without posing risks to human health and safety.
Innovation Solution
The development of an ozone gas generating device that can operate in two modes: a regular mode and a 'turbocharged' mode, which increases ozone gas production only after ensuring that no human or living creatures are present in the area, using remote motion sensors and UV irradiation to safely generate ozone gas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If high concentrations of ozone gas are generated in enclosed spaces, then antimicrobial effectiveness is improved, but human safety is compromised
Solution Approach 1:
The system dynamically adjusts ozone generation between two distinct modes (regular mode and turbocharged mode) based on real-time occupancy detection. Motion sensors continuously monitor the space, and the controller automatically transitions between operational states to match safety requirements with disinfection needs, making the ozone concentration adaptive rather than static.
Solution Approach 2:
The system performs preliminary safety verification by detecting occupancy before allowing high-concentration ozone generation. The motion sensors and controller establish a safe state confirmation process that must be completed before transitioning to turbocharged mode, ensuring that high ozone levels are only produced when the space is verified to be unoccupied.
2Productivity
If ozone gas production is increased to achieve effective disinfection, then germicidal effectiveness is improved, but safety risks increase
Solution Approach 1:
The system employs dynamic operational modes that adjust productivity based on safety conditions. The controller manages transitions between regular mode (lower productivity, always safe) and turbocharged mode (high productivity, safe only when unoccupied), allowing the system to maximize disinfection effectiveness when safe while maintaining reliable safety protection.
Solution Approach 2:
The system uses feedback from motion sensors to control ozone generation. The controller continuously receives occupancy information and adjusts the ozone production rate accordingly, creating a closed-loop control system where safety feedback directly regulates productivity to prevent harmful exposure while enabling effective disinfection when appropriate.
3Loss of time
If the system operates in turbocharged mode to quickly generate ozone, then disinfection speed is improved, but risk of harmful exposure increases
Solution Approach 1:
The system performs preliminary occupancy verification through motion sensors before enabling turbocharged mode. This preliminary safety check ensures that the fast, high-concentration ozone generation only occurs when the space is confirmed unoccupied, eliminating exposure risk while maintaining the time efficiency benefit of rapid disinfection.
Solution Approach 2:
The system dynamically switches between operational speeds based on real-time safety conditions. The controller enables rapid turbocharged operation when safe (reducing disinfection time) and automatically switches to slower regular mode when occupancy is detected, making the disinfection speed adaptive to safety requirements rather than fixed.
