Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Microfluidic devices face challenges in increasing the number of emulsions formed without making the device bulky and costly, while maintaining user-friendly interfaces and reliability, as smaller devices with higher density arrays become difficult to load and seal effectively.
Innovation Solution
A microfluidic device comprising a frame with multiple modules mounted by snap-fit attachment, featuring a sealing member that hermetically seals each module, and a stack of layers with port layers forming ports with protrusions for easy bonding and sealing, facilitating the formation of an array of emulsions with improved loading and sealing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of emulsions in the array is increased to meet higher sample throughput demand, then productivity is improved, but the device becomes bulky and manufacturing cost increases
Solution Approach 1:
The device is divided into multiple separate microfluidic modules, each capable of forming an array of emulsions independently. These modules are mounted to a common frame, allowing the system to achieve high throughput by operating multiple smaller units in parallel rather than one large complex device.
Solution Approach 2:
The patent transitions from increasing array density in a single plane to adding modules in a vertical dimension by mounting multiple modules to a frame. This dimensional approach allows scaling throughput without proportionally increasing the device's horizontal footprint.
2Area of stationary object
If the array density is increased to reduce device size, then device compactness is improved, but user interface and instrument interface size are reduced making the device less user-friendly and more expensive
Solution Approach 1:
By segmenting the device into separate modules, each module can maintain standard interface sizes for user-friendly operation while the overall system remains compact. The modular architecture allows standardization of interfaces without sacrificing compactness.
3Area of stationary object
If the array density is increased to reduce device size, then device compactness is improved, but manufacturing reliability decreases due to difficulty in loading and sealing
Solution Approach 1:
Segmenting into separate modules allows each module to be manufactured, loaded, and sealed independently using standard processes, thereby maintaining high reliability. The modular approach avoids the need for complex high-density integration that would compromise manufacturing reliability.
Solution Approach 2:
Multiple independent modules are merged onto a common frame structure, combining their functions while maintaining individual manufacturing and sealing processes. This merging achieves compactness without sacrificing the reliability of individual module fabrication.

AI summary
Systems, methods, and devices for forming an array of emulsions. An exemplary device comprises a frame and at least one or a plurality of separate microfluidic modules mounted to the frame and each configured to form an array of emulsions. In some embodiments, each module may be mounted by snap-fit attachment. The device also may include the same sealing member bonded to a top side of each module and hermetically sealing each of the modules. Another exemplary microfluidic device for forming an array of emulsions comprises a stack of layers bonded together. The stack may comprise a port layer forming a plurality of ports. Each port may have a top rim formed by a protrusion that encircles the central axis of the port. The rims may be coplanar with one another to facilitate bonding of a sealing member to each rim.
