Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing devices for adhesives and sealants lack the ability to optimize mixing performance and quality, particularly in adapting to different mixing tips and fluid flow rates.
Innovation Solution
The development of an adapter for mixing devices that includes a conduit with inlets and an outlet, configured to maintain the separation of fluid feeding materials until they exit the outlet, allowing for modular adaptation to different delivery units and mixing tips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a static delivery system is used, then the device structure is simple, but the mixing performance and quality are insufficient
Solution Approach 1:
The mixing device is divided into separate modular components: a delivery unit and interchangeable mixer tips. This segmentation allows the static delivery system to remain simple while the mixer tips provide the necessary mixing performance through their internal geometry and flow path design.
Solution Approach 2:
The mixer tips are designed with dynamic flow paths that create turbulent flow patterns and fluid interaction as materials pass through. The internal geometry of the mixer tips dynamically mixes fluids through flow-induced motion rather than mechanical moving parts, maintaining structural simplicity while achieving effective mixing.
2Adaptability or versatility
If mixing tips are made interchangeable and modular, then the adaptability and mixing effect are enhanced, but the device complexity increases
Solution Approach 1:
The delivery unit is designed with a universal coupling interface that can accommodate multiple types of mixer tips. This universal interface allows the same delivery unit to work with various mixer tip configurations, enhancing adaptability without requiring multiple delivery units or complex switching mechanisms.
Solution Approach 2:
The mixer tips are designed to attach to and be contained within the delivery unit structure. The modular tips nest into the delivery unit through a standardized interface, allowing easy interchange while maintaining a compact integrated appearance and minimizing overall device complexity.
3Productivity
If the fluid flow rate is decoupled from the delivery unit, then the mixing speed can be increased, but the control complexity increases
Solution Approach 1:
The mixer tips are designed with varying internal geometries, flow path lengths, and restriction characteristics that naturally regulate fluid flow rates. By changing the physical parameters of the mixer tip geometry rather than using active control systems, different mixing speeds and flow rates are achieved through passive flow regulation.
Solution Approach 2:
The decoupling of fluid flow rate control from the delivery unit allows each mixer tip to self-regulate its own flow characteristics based on its internal geometry. The mixer tip design inherently controls the flow rate and mixing intensity without requiring external control mechanisms, simplifying the overall control system.
