Solution Overview
Problem
Existing mixing impellers in the paint industry fail to achieve homogeneous dispersion of insoluble particles, requiring longer times and higher power consumption due to inadequate disintegration and dispersion mechanisms, particularly in high-viscosity paints.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional mixing impellers are used, then the structure is simple and easy to manufacture, but the dispersion homogeneity of particles is insufficient
Solution Approach 1:
The impeller is segmented into distinct functional zones: a dispersion zone with upward-disposed blades for initial particle breakdown, a mixing zone with downward-disposed blades for homogenization, and a central axial flow element. This segmentation allows each zone to perform its specific function optimally, achieving high dispersion homogeneity through coordinated action of multiple blade groups rather than a single uniform structure.
Solution Approach 2:
Different regions of the impeller have locally optimized properties: the outer dispersion zone features blades with specific pitch angles for cutting particle aggregates, the central region has axial flow elements for vertical circulation, and the mixing zone has blades configured for radial and axial flow patterns. Each local region is designed with specific blade geometries and orientations tailored to its functional requirements, achieving overall superior dispersion performance.
2Productivity
If conventional mixing impellers are used, then the device complexity is low, but the mixing time is excessive
Solution Approach 1:
The mixing process is segmented into parallel simultaneous actions: the upward-disposed blades perform dispersion in one region while downward-disposed blades perform mixing in another region, and the central axial flow element creates vertical circulation. This parallel segmentation of mixing functions across different spatial zones dramatically reduces total mixing time compared to sequential mixing with simpler impellers.
Solution Approach 2:
The impeller design incorporates three-dimensional flow patterns by combining radial blade movements with axial flow elements. The central axial flow component creates vertical circulation that adds a third dimension to the mixing action, enhancing mixing efficiency and reducing mixing time by engaging fluid in multiple spatial dimensions simultaneously rather than relying solely on planar rotation.
3Manufacturing precision
If conventional mixing impellers are used, then the power consumption is high, but the dispersion effectiveness is insufficient
Solution Approach 1:
The energy input is segmented and distributed across multiple blade groups performing different functions: upward blades perform high-energy dispersion of aggregates, while downward blades perform lower-energy homogenization. This segmentation allows energy to be applied at appropriate intensities to each mixing stage, achieving effective particle disintegration without the excessive power consumption required by single-stage high-intensity mixers.
Solution Approach 2:
The blade pitch angles and orientations are precisely controlled parameters that optimize energy transfer efficiency. By setting specific pitch angles for upward and downward blades, the design maximizes the mechanical energy transferred to particles for disintegration while minimizing energy wasted in turbulent eddies and heat generation, achieving high dispersion effectiveness with optimized power consumption.
