Elliptical Ink Container Agitator for Vertical Mixing

The patent applies asymmetry by changing the container cross-section from a symmetric circular shape to an asymmetric elliptical or oval shape. This asymmetric geometry creates non-uniform flow patterns during agitation, generating both horizontal and vertical mixing currents that effectively prevent ink separation while maintaining manufacturing feasibility.

The patent avoids the corner stagnation problem of polygonal containers by using an elliptical or oval cross-section that maintains smooth curved surfaces without sharp corners. This asymmetric curved geometry ensures continuous fluid flow throughout the entire container volume, preventing stagnation zones while optimizing space utilization compared to circular containers.

The asymmetric elliptical or oval container geometry creates enhanced flow circulation patterns that improve mixing efficiency at lower agitation speeds. The non-uniform cross-section generates natural vertical and horizontal currents that facilitate complete ink mixing without requiring high energy input, thus resolving the contradiction between mixing speed and energy consumption.

The asymmetric elliptical or oval container geometry modifies the fluid dynamics during agitation to reduce air entrapment and inclusion formation. The non-uniform flow patterns created by the asymmetric shape promote more gradual and controlled mixing, minimizing air pocket formation and reducing contamination risks while maintaining simple mixing device structures.
