Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional electrochemical ozone generation systems are used, then ozone gas can be produced, but the systems become bulky, expensive, and difficult to maintain
Solution Approach 1:
The patent replaces complex electrochemical generation systems with a simpler dielectric barrier discharge system. The invention uses a dielectric cell with electrodes separated by a dielectric material to generate ozone through electrical discharge, eliminating the need for complex electrochemical reactors, pumps, and control systems while achieving high ozone concentrations in a compact form factor
Solution Approach 2:
The invention changes the operational parameters by using high voltage, low current electrical discharge through a dielectric barrier to generate ozone. This parameter change from conventional electrochemical methods enables compact system design while maintaining high ozone production efficiency and simplifying the overall system architecture
2Quantity of substance
If high ozone concentration is achieved for effective cleaning, then sanitizing capability improves, but ozone off-gassing increases creating safety concerns
Solution Approach 1:
The patent incorporates an injector system that uses water flow to entrain and mix with ozone gas. The hydraulic flow creates a vacuum effect that draws ozone into the water stream, efficiently transferring ozone from gas phase to liquid phase and minimizing off-gassing while delivering high concentrations of ozone to the dispensing point
3Ease of operation
If existing systems are used to provide ozonated liquid, then some cleaning capability is achieved, but sufficient ozone concentration for effective sanitizing is not provided
Solution Approach 1:
The patent merges the ozone generation function with the liquid dispensing function in a single integrated unit. The dielectric cell generates ozone that is immediately mixed with water through the injector system, producing ozonated liquid on-demand at high concentrations. This integration eliminates the need for separate ozone generators and mixing equipment, ensuring sufficient ozone concentration is maintained throughout the dispensing process
