Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional disinfection practices are used, then water can be treated, but certain pathogens like Cryptosporidium remain resistant and disinfection byproducts are formed
Solution Approach 1:
The patent changes the chemical parameter of disinfection by using ozone instead of traditional chlorine-based disinfectants. Ozone (O3) is a stronger oxidizing agent that can effectively kill Cryptosporidium and other resistant pathogens without forming harmful byproducts like trihalomethanes and haloacetic acids. The system monitors ORP to ensure adequate disinfection levels are achieved.
Solution Approach 2:
The patent employs ozone, a strong oxidant, to accelerate the disinfection process. Ozone molecules directly oxidize and destroy pathogen cell walls and membranes, providing rapid and effective disinfection. The oxidation-reduction potential (ORP) monitoring ensures that sufficient oxidizing power is maintained throughout the water distribution system.
2Quantity of substance
If intermediate tanks are used for high pressure water applications, then mixing can be achieved, but system complexity and space requirements increase
Solution Approach 1:
The patent extracts the mixing function from a separate intermediate tank and integrates it directly into the water distribution pipes. The ozone injection ports are installed directly in the pipes, allowing ozone to be injected and mixed with water in-line, eliminating the need for separate storage and mixing tanks while maintaining effective ozone solution preparation.
Solution Approach 2:
The patent merges the ozone injection, mixing, and distribution functions into a single integrated pipe system. The control valve, ozone injection ports, and water flow path are combined in the pipe assembly, creating a compact system that performs multiple functions without requiring separate intermediate tanks or complex external mixing equipment.
3Reliability
If control valves are used to regulate water flow, then ORP levels can be maintained, but pressure drops may occur
Solution Approach 1:
The patent uses a dynamic control valve that automatically adjusts its opening based on real-time ORP measurements. When ORP levels are sufficient, the valve closes to prevent excess ozone injection and pressure drop. When ORP levels decrease, the valve opens to allow more ozone injection. This dynamic adjustment maintains ORP levels while minimizing unnecessary pressure losses.
Solution Approach 2:
The system implements a feedback control loop where the ORP sensor continuously monitors disinfection levels and sends signals to the control valve. The controller adjusts the valve position based on ORP readings, creating a closed-loop system that maintains optimal disinfection levels while regulating water flow and minimizing pressure drops through intelligent control.

AI summary
A system for creating an oxidation reduction potential (ORP) in water employs a pipe assembly for in-line mixing. The pipe assembly includes a first flow path for water to flow through. The first flow path includes one or more ozone intake ports that are fluidically coupled to one or more ozone output ports of an ozone supply unit. The pipe assembly further includes a second flow path fluidically coupled in parallel with the first flow path. The second flow path includes a control valve that selectively permits a portion of the water to flow through the second flow path to produce a negative pressure in the first flow path so that ozone is drawn into the first flow path through the one or more ozone intake ports and mixed into the water flowing through the first flow path.
