Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If heterogeneous microfluidic devices are integrated into a single package, then multi-physic integration and functionality are improved, but maintaining smooth fluidic flow between devices becomes difficult
Solution Approach 1:
The microfluidic system is divided into multiple discrete devices that are embedded separately into the substrate. Each device can be fabricated using different materials and processes, then integrated into the same package with fluidic channels connecting them, allowing heterogeneous integration while maintaining proper fluid flow between segments
Solution Approach 2:
Fluidic channels act as intermediary elements that connect heterogeneous microfluidic devices embedded in the substrate. These channels ensure smooth fluid flow between devices with different materials and fabrication processes, mediating the interface between diverse components
2Adaptability or versatility
If diverse microfluidic devices made of different materials are integrated, then device functionality and sensing capabilities are improved, but manufacturing cost and complexity increase
Solution Approach 1:
Multiple microfluidic devices made of different materials (such as silicon, glass, and polymers) are merged and embedded into a single substrate package. This combining approach allows diverse functionalities to be integrated while sharing common fabrication infrastructure and packaging processes, reducing overall manufacturing complexity
Solution Approach 2:
The substrate serves as a universal platform that can accommodate different types of microfluidic devices with various materials and functions. This multi-functional substrate design allows a single manufacturing process to produce devices with diverse sensing and actuation capabilities
3Use of energy by moving object
If microfluidic devices are made at sub-millimeter scale, then energy consumption is reduced, but maintaining smooth fluidic flow becomes challenging
Solution Approach 1:
The system transitions from two-dimensional planar fluid flow to three-dimensional embedded architecture. Microfluidic devices are embedded within the substrate volume, allowing fluid channels to route around obstacles and maintain smooth flow paths while keeping device footprint at sub-millimeter scale, thus preserving low energy consumption
