Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual asymmetric centrifugal mixers lack the capability to reliably and consistently perform comminution, necessitating the use of multiple equipment for both mixing and grinding, which is costly and inconvenient for users.
Innovation Solution
A grinding adapter for dual asymmetric centrifugal mixers that includes an inner compartment for grinding media and openings for material flow, enabling efficient comminution by centrifugal force, with optional strainer support for residual material removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a dual asymmetric centrifugal mixer is used for mixing materials, then mixing homogeneity is improved, but grinding capability deteriorates (cannot perform comminution)
Solution Approach 1:
The patent applies multi-functionality by enabling the centrifugal mixer to perform both mixing and grinding operations through the addition of a grinding adapter. The adapter includes an inner compartment for grinding media and openings for material flow, allowing the same device to reliably execute comminution while maintaining its mixing capability.
2Adaptability or versatility
If multiple pieces of equipment are used for both mixing and grinding, then functional versatility is improved, but device complexity and cost deteriorate
Solution Approach 1:
The patent eliminates the need for separate grinding equipment by implementing a universal centrifugal mixer that can perform both mixing and grinding functions through an interchangeable grinding adapter, thereby reducing the total number of equipment pieces while maintaining full functional versatility.
Solution Approach 2:
The grinding adapter is nested within the container of the centrifugal mixer, with the inner compartment containing grinding media. This nested structure allows the grinding function to be integrated into the existing mixing device without requiring separate equipment.
3Productivity
If the adapter includes openings for material flow, then material circulation is improved, but grinding media retention deteriorates (risk of media leaving adapter)
Solution Approach 1:
The patent applies local quality by designing openings with specific size characteristics that are locally optimized to allow ground material to pass through while retaining larger grinding media. The openings have dimensions that create a selective filter effect, permitting productive material circulation while ensuring reliable media retention.
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
Enables efficient, reliable, and reproducible grinding of materials within a single dual asymmetric centrifugal mixer, reducing the need for multiple equipment and minimizing material waste.
Implementation Method 1
Centrifugal force is then applied by the dual asymmetric centrifugal mixer to the container. The centrifugal force results in comminution between the one or more materials and the grinding media
