Engineering Contradiction Analysis
1Duration of action of moving object
If conventional tower dissolution chamber is used with counter-current flow, then contact time for ozone dissolution is increased, but the concentration of dissolved ozone is diluted and the chamber height becomes large
Solution Approach 1:
The patent employs curved flow passages with specific radii of curvature to induce vortex flow patterns. The curved geometry transforms linear flow into rotational flow, increasing contact time between ozone and water without requiring additional vertical space. This resolves the contradiction by using geometric curvature to achieve extended interaction time in a compact footprint.
Solution Approach 2:
The invention transitions from vertical counter-current flow (one-dimensional) to horizontal vortex flow with rotational components (two-dimensional/three-dimensional). By introducing radial and tangential flow components through curved passages, the system achieves enhanced mixing and contact time without increasing chamber height, effectively utilizing additional spatial dimensions.
2Productivity
If turbulent flow is maintained in dissolution chamber, then mixing is enhanced, but ozone destruction increases requiring destruct units
Solution Approach 1:
The patent creates dynamic vortex flow patterns through curved passages that maintain continuous motion and mixing. The rotational flow provides sustained mixing efficiency while being more gentle than turbulent flow, reducing ozone destruction. The dynamic nature of the vortex ensures effective contact between phases without the excessive energy dissipation associated with turbulence.
Solution Approach 2:
The invention changes the flow regime parameters from high-intensity turbulence to controlled vortex flow with specific velocity profiles and rotation rates. By adjusting the flow parameters through optimized passage curvature and dimensions, the system achieves adequate mixing while operating in a lower-energy regime that preserves ozone concentration.
3Object-generated harmful factors
If swept flow passage with concave curvature is used, then vortex flow is induced reducing turbulence, but the inducer body complexity increases
Solution Approach 1:
The patent applies curvature and sweeping only to specific regions of the flow passage where vortex induction is most effective, rather than complicating the entire chamber geometry. The curved passages are strategically positioned to generate the desired flow patterns with minimal additional complexity. This localized application of geometric features achieves turbulence reduction without uniformly increasing device complexity throughout the entire system.

AI summary
A vortex flow inducer has inducer body with an interior end, an outer end and a length extending there between, and a longitudinal axis extending between the interior and the outer ends. A flow passage extends between the interior and outer ends of the inducer body. The flow passage has an inlet at the outer end and an exit at the interior end. The flow passage is swept laterally toward a side of the inducer body in a direction from the outer end toward the interior end such that the exit is laterally offset from the longitudinal axis. The interior end of the inducer body has a concave curvature. The swept flow passage and the curved interior end induce a vortex flow in a fluid flowing through the flow passage as it exits the flow passage and into a flow passage of a conduit the that extends at an angle relative to the longitudinal axis of the inducer body.
