Engineering Contradiction Analysis
1Reliability
If high pressure is used to pump fluid through the mixing chamber elements, then mixing quality and energy dissipation are improved, but flow resistance increases and exit fluid flow rate decreases
Solution Approach 1:
The patent applies curved flow paths instead of sharp angles in the mixing chamber elements. The curved geometry allows fluid to transition smoothly between directions, reducing flow resistance and turbulence while maintaining effective mixing. This curvature principle enables higher exit flow rates at lower pressures while preserving mixing quality.
2Reliability
If high pressure is used to overcome flow resistance, then acceptable mixing conditions are achieved, but energy consumption increases
Solution Approach 1:
The curved flow paths in the mixing chamber elements reduce the energy required to move fluid through the system. By eliminating sharp angles and optimizing flow transitions, the design reduces pressure losses and energy dissipation while maintaining effective mixing conditions, thus lowering overall energy consumption.
Solution Approach 2:
The patent optimizes geometric parameters of the mixing chamber elements, including curvature radius, channel dimensions, and flow path length, to achieve efficient mixing at lower pressures. These parameter optimizations reduce the energy input required while maintaining mixing quality.
3Productivity
If geometric design is optimized for flow efficiency, then exit flow rate increases, but mixing thoroughness may be compromised
Solution Approach 1:
The curved flow paths are designed to balance flow efficiency with mixing effectiveness. The curvature allows fluid to follow a controlled path that maximizes contact between streams while minimizing resistance, achieving both high exit flow rates and thorough mixing without compromise.

AI summary
A mixing assembly includes an inlet, an outlet and a mixing chamber, the inlet is fluidly connected to the outlet through a plurality of micro fluid flow paths in a direction perpendicular from the inlet. The micro fluid flow paths fluidly connect to the perpendicular inlet via a curved transition portion. The curved transition portion provides a more efficient flow path for the fluid to travel from the inlet to the micro fluid flow paths to the mixing chamber. By transitioning the direction change, flow resistance is decreased, and the fluid flow rate and shear rate is increased. Increased fluid flow rate and shear rate helps to increase consistency and quality of mixing, and to reduce particle size of the fluid in the mixing chamber.
