Concentric Ring Mixing Device for Two-Component Adhesive Homogeneity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing devices for two-component adhesives within dispenser devices fail to produce a homogeneous mixture effectively, necessitating improved mixing efficiency.
Innovation Solution
A mixing device comprising a base panel with concentrically arranged ring elements, where the inner ring element receives adhesive component B and the outer ring element receives component A, with passage openings to facilitate radial movement and mixing, ensuring component B is directed into the conveying direction of component A for effective mixing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If conventional mixing devices are used to mix two-component adhesives directly within the dispenser, then the need for manual prior mixing is eliminated, but the mixing effectiveness is insufficient to produce a homogeneous mixture
Solution Approach 1:
The mixing device is segmented into distinct functional zones: an outer ring element receiving component A, an inner ring element receiving component B, and multiple passage openings distributed throughout. This segmentation allows separate introduction of components while providing multiple mixing interfaces, improving homogeneity while maintaining automatic operation.
Solution Approach 2:
The invention introduces radial flow paths perpendicular to the main conveying direction. Component B is conveyed radially inward through the inner ring element, while component A flows axially, creating orthogonal mixing zones. This dimensional change enhances mixing effectiveness by forcing components to intersect at right angles, producing more homogeneous mixtures.
2Manufacturing precision
If components are forced to move radially perpendicular to the conveying direction to improve mixing, then mixing effectiveness increases, but the device structure becomes more complex
Solution Approach 1:
The ring elements serve multiple functions simultaneously: they act as receiving chambers for respective components, provide structural support for passage openings, define flow paths, and create mixing zones. This multi-functionality reduces the need for additional separate components, maintaining relative structural simplicity while achieving improved mixing homogeneity through radial flow paths.
