Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional ozone generators are used for commercial cleaning and sanitizing, then ozone generation capability is achieved, but the devices become large, heavy, and difficult to transport
Solution Approach 1:
The ozone generator is divided into separate functional modules: a power supply unit, a corona discharge chamber with aluminum electrode and wire mesh, and a housing that can be disassembled. This segmentation allows the heavy power supply to be separated from the lightweight discharge chamber, enabling portable operation while maintaining ozone generation capability.
Solution Approach 2:
The power supply is extracted as a separate removable component from the main housing. This allows the core ozone generation chamber to be lightweight and portable, while the power supply can be transported separately or removed from the device when not in use, significantly reducing the weight of the portable unit.
2Reliability
If conventional ozone generators are used for commercial cleaning, then sanitizing function is provided, but the devices are large and unwieldy to use
Solution Approach 1:
The device is segmented into modular components including a removable power supply, a fan assembly, and a corona discharge chamber. This modularity simplifies operation as users can easily assemble and disassemble the unit for portable use, while the standardized components ensure reliable sanitizing function.
Solution Approach 2:
The device incorporates automatic control features where the power supply automatically activates the corona discharge and fan when connected, and includes safety features that automatically shut down the system if abnormal conditions are detected, reducing the operational burden on the user while maintaining reliable sanitizing function.
3Quantity of substance
If conventional ozone generators are used for commercial purposes, then ozone generation is achieved, but power efficiency is poor
Solution Approach 1:
The corona discharge parameters are optimized by controlling the voltage (10,000 volts), electrode geometry (aluminum plate with wire mesh), and gas flow rate (via fan control). These parameter optimizations maximize ozone generation efficiency per unit of electrical energy consumed, improving power efficiency while maintaining high ozone output.
Solution Approach 2:
The device continuously generates ozone as long as power is supplied and air flows through the corona discharge chamber, eliminating idle time and maximizing the utilization of electrical energy for ozone production. The fan ensures continuous fresh air supply to the discharge chamber, maintaining optimal conditions for efficient ozone generation throughout operation.

AI summary
An ozone generator is contained in a housing having a fan for inducing air flow through the housing and over an ozone generating plate where atmospheric oxygen is electrochemically converted to ozone, which flows out of the housing through a grid opening. The ozone generating plate is defined by a glass plate having electrically conductive grids on both sides thereof and each grid is electrically powered to create corona discharge from the conductor; as air and oxygen in the air flows over the plate it is converted to ozone.
