Coaxial Nozzle for Simultaneous Viscous Material Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for filling containers with multiple viscous materials are complex and time-consuming, requiring multiple operations and nozzle cleaning cycles, which increases costs and operational complexity.
Innovation Solution
A nozzle design with two coaxial cylindrical chambers and a single delivery mouth allows simultaneous filling of two viscous materials through separate outflow sections, facilitated by an inner cylindrical body and a coaxial auxiliary fluid tube that can be easily cleaned using compressed air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple nozzles are used to fill a container with at least two viscous materials, then the filling operation can be performed simultaneously, but the device complexity and cleaning requirements increase
Solution Approach 1:
The single nozzle is segmented into multiple independent chambers (first chamber for first viscous material, second chamber for second viscous material) that are fluidly separated. Each chamber has its own outflow section positioned at the delivery mouth, allowing simultaneous delivery of multiple materials through a unified nozzle structure without cross-contamination
Solution Approach 2:
The nozzle is designed as a multi-functional device that can deliver at least two different viscous materials through a single structure. The nozzle universally handles multiple materials by providing separate chambers for each material while maintaining a common delivery mouth, eliminating the need for multiple separate nozzles
2Device complexity
If the same nozzle is used to deliver different viscous materials in sequence, then device complexity is reduced, but cleaning time and operational complexity increase
Solution Approach 1:
The nozzle chambers are completely fluidly separated with independent outflow sections, allowing each chamber to be cleaned independently or simultaneously without affecting the other material delivery paths. This segmentation enables rapid cleaning operations without requiring complete nozzle disassembly or affecting the other material supply
Solution Approach 2:
The design allows for continuous operation by enabling quick cleaning transitions between materials. The fluid separation and independent outflow sections ensure that cleaning one material path does not interrupt the supply or cleaning of other material paths, maintaining continuous productive action
3Reliability
If multiple nozzles are used to avoid contamination, then material purity is maintained, but the number of cleaning operations and resources required increases
Solution Approach 1:
Complete fluid separation is achieved through independent chambers with separate outflow sections positioned at the delivery mouth. Each chamber maintains material purity through physical separation while sharing a common delivery interface, eliminating cross-contamination risks without requiring multiple separate nozzles that would consume more cleaning resources
