Mobile Ozonated Water Dispenser With External Generator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The widespread use of ozonated water as a biocide is limited by the high cost and inefficiency of existing ozone generation systems, which require each mobile apparatus to have its own ozone generator, and the difficulty in achieving high ozone concentrations at the point of use.
Innovation Solution
A mobile device for dispensing ozonated liquid that connects to an external ozone generator for charging, allowing multiple units to be serviced by a single generator, with features like a pump for circulating water, a refrigeration system, and an ozone gas destruction system to manage ozone concentration and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each mobile apparatus has its own ozone generator, then the apparatus can supply ozonated water independently, but the cost increases significantly
Solution Approach 1:
The system is divided into two parts: a stationary ozone generator and mobile dispensing units. The ozone generator remains fixed while multiple mobile units can be charged and deployed independently, reducing the cost of each mobile unit while maintaining operational independence through the ability to be charged from the central generator.
Solution Approach 2:
The stationary ozone generator serves multiple mobile dispensing units, making it a universal resource that can service various applications and locations. This multi-functional approach allows a single generator to support numerous mobile units across different departments or facilities.
2Quantity of substance
If ozone is generated continuously, then high concentration can be maintained, but the cost and energy consumption increase
Solution Approach 1:
The ozone generator operates periodically rather than continuously. Mobile units are charged during off-peak times or when ozone generation capacity is available, then deployed when needed. This periodic operation maintains high ozone concentrations in the mobile units while reducing overall energy consumption and operational costs.
Solution Approach 2:
Mobile dispensing units are pre-charged with ozonated water before deployment to the point of use. This preliminary action allows the units to be stocked with high-concentration ozone solution in advance, eliminating the need for continuous generation during actual use and reducing energy consumption during critical dispensing periods.
3Ease of operation
If ozone generator is integrated into mobile device, then portability is achieved, but the device complexity and cost increase
Solution Approach 1:
The ozone generator is extracted from the mobile dispensing unit and placed in a fixed location. The mobile unit contains only the reservoir, pump, and dispensing mechanisms, significantly reducing its complexity and cost. The generator remains stationary while mobile units can be easily transported and deployed to various locations.

Implementation Method 2
receive oxygen gas which is converted to ozone using the corona discharge method
Implementation Method 3
a refrigeration system to cool the liquid. The liquid may be cooled to a set temperature
Implementation Method 4

AI summary
A device and method for supplying ozonated liquid is disclosed. Liquid in a reservoir is pumped from the reservoir to a separate ozone generator and is thereby ozonated. The ozonated liquid is retained to the reservoir so that the liquid is circulated in a loop. As the liquid is circulated through the ozone generator, the concentration of ozone increases. Once the liquid has been sufficiently ozonated, the generator is disconnected and the reservoir moved to where ozonated water is required and ozonated water is dispensed from the reservoir.
