Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional disinfection practices (chlorine) are used, then pathogen control is achieved, but harmful disinfection byproducts (trihalomethanes, haloacetic acids) are formed
Solution Approach 1:
The patent changes the chemical parameter of the disinfectant from chlorine to ozone, which has different oxidation properties. Ozone generates hydroxyl radicals that non-selectively oxidize organic contaminants without forming harmful byproducts like trihalomethanes and haloacetic acids, while still achieving effective pathogen control.
Solution Approach 2:
The patent employs ozone, a strong oxidant, to accelerate the oxidation process for pathogen control. Ozone decomposes to form hydroxyl radicals that rapidly oxidize microbial cell walls and organic contaminants, providing enhanced disinfection effectiveness without the harmful byproduct formation associated with traditional chlorine-based disinfection.
2Speed
If high pressure water applications are used, then water flow and distribution are improved, but mixing and distribution of water and ozone solution becomes challenging
Solution Approach 1:
The patent utilizes hydraulic principles by injecting ozone gas directly into the high-pressure water stream. The high-velocity water flow creates turbulence and shear forces that effectively mix and distribute the ozone throughout the water, eliminating the need for complex intermediate mixing tanks or additional pumping systems.
Solution Approach 2:
The patent removes the intermediate ozone mixing tank from the system, allowing ozone to be injected directly into the high-pressure water line. This extraction of the mixing chamber simplifies the overall system architecture while maintaining effective ozone-water mixing through the inherent turbulence of high-pressure flow.
3Stability of the object's composition
If intermediate tanks are used for ozone mixing, then mixing effectiveness is improved, but system complexity and space requirements increase
Solution Approach 1:
The patent extracts and eliminates the intermediate ozone mixing tank from the system architecture. Instead, ozone is injected directly into the high-pressure water line where the existing flow dynamics provide sufficient mixing, thereby reducing system complexity and space requirements while maintaining effective ozone-water composition.
Solution Approach 2:
The patent allows the high-pressure water flow itself to perform the mixing function that would otherwise require a separate mixing tank. The kinetic energy and turbulence of the water stream automatically mix the injected ozone throughout the flow, making the system self-mixing without additional equipment.

Implementation Method 1
transportable system for creating an oxidation reduction potential (ORP) in water
Implementation Method 2
A first flow path (302) for water to flow through. The first flow path includes one or more ozone intake ports (316) that are fluidically coupled to the one or more ozone output ports (220) of the supply unit enclosure (202). A second flow path (304) fluidically coupled in parallel with the first flow path (302). The second flow path (304) includes a control valve (306) that selectively permits a portion of the water to flow through the second flow path (304) to produce a negative pressure in the first flow path (302) so that ozone is drawn into the first flow path (302)
