Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stirring tools for mixing fluids, particularly those with high viscosity or in small containers, fail to achieve satisfactory homogeneity due to insufficient mixing energy and displacement, leading to inadequate shearing effects.
Innovation Solution
A stirring tool with a rotor disk featuring multiple fluidically connected axial and radial/tangential bores that generate centrifugal forces, inducing negative pressure and turbulence for enhanced mixing, including conical designs to prevent vortex formation and improve component distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional stirring tools are used to mix fluids in small containers, then the device complexity remains simple, but the mixing quality and homogeneity are insufficient
Solution Approach 1:
The rotor disk is segmented into multiple flow channels (at least three) with axial and radial bores, dividing the mixing function into multiple localized flow paths that collectively achieve homogeneous mixing without requiring complex overall device structure
Solution Approach 2:
The invention utilizes fluid dynamic principles by creating controlled flow channels through the rotor disk that guide liquid flow patterns, using the hydraulic action of the liquid itself to achieve mixing without additional mechanical complexity
2Power
If conventional stirring tools are used for high-viscosity components, then the device structure remains simple, but the mixing energy and shearing effect are insufficient
Solution Approach 1:
The rotor disk is designed to rotate at controlled speeds, creating dynamic flow patterns through centrifugal forces that enhance mixing energy for high-viscosity materials without requiring overly complex mechanical drive systems
Solution Approach 2:
The invention introduces vertical flow components through axial bores in addition to radial flow, creating three-dimensional flow patterns that increase shearing effects and mixing energy utilization without proportionally increasing device complexity
3Productivity
If mixing is performed in small containers, then the device size remains compact, but the displacement effect and mixing efficiency are reduced
Solution Approach 1:
The flow channels are strategically positioned and sized to create localized high-velocity flow regions within the compact rotor disk, concentrating mixing action where most needed in small containers to maximize efficiency without increasing overall device volume
Solution Approach 2:
The invention replaces reliance on purely mechanical displacement with fluid dynamic forces generated by the rotating flow channels, using centrifugal and pressure-driven flow to achieve enhanced mixing efficiency in compact volumes
4Force
If conventional open-channel mixing blades are used, then the device structure remains simple, but the forced flow effect is limited and material rotation occurs
Solution Approach 1:
The flow channels are designed with asymmetric configurations, with axial bores positioned at specific radii and angles relative to radial bores, creating unbalanced flow patterns that generate stronger forced flow effects while preventing container rotation through counteracting moments
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tool achieves strong local mixing and rapid reproducibility of homogeneous mixtures, effectively handling components of different consistencies and gases within short stirring times, improving mixing quality and stability.
Implementation Method 1
the centrifugal forces generated by the rotor disk create a negative pressure in the flow channels, which induces an additional vertical flow in the component mixture
Implementation Method 2
partial flows are sucked in from the material to be mixed, deflected in the axial bores and discharged from the radial or tangential bores, with strong turbulence being generated

AI summary
The stirring tool has a driving agitator shaft (1) and an end sided single piece fixed rotor disk (2), which has a multiple flow through channel. The gaseous and/or fine-grained components contain a mixture of two components. The flow through channels consists of symmetrically arranged axial drillings (3) and radial or tangential drillings (4). The axial drilling stands in interaction with a radial or tangential drilling in each case.
