Engineering Contradiction Analysis
1Reliability
If a traditional integrated active surface is used in microfluidic systems, then the system can process biological materials, but the cost and complexity of providing the active surface increases significantly
Solution Approach 1:
The active surface is separated from the microfluidic cartridge into independent modular devices. Each active surface device can be tested and validated separately before integration, reducing system complexity while maintaining processing capability. The modular design allows the active surface to be provided as a discrete component rather than an integrated system.
2Reliability
If a traditional integrated active surface is used in microfluidic systems, then the system can process biological materials, but the cost of providing the active surface increases significantly
Solution Approach 1:
By segmenting the active surface into separate modular devices, manufacturing costs are reduced through standardized production of discrete components. The active surface devices can be manufactured independently using optimized processes, avoiding the need for complex integrated manufacturing of the entire microfluidic system.
Solution Approach 2:
The modular active surface devices are designed to be universally compatible with different microfluidic cartridges through standardized interfaces. This multi-functionality allows a single active surface device design to serve multiple applications, reducing development and manufacturing costs across different product lines.
3Reliability
If an active surface is integrated into a microfluidic system, then biological materials can be processed, but barriers to testing the active surface performance are created
Solution Approach 1:
The active surface is provided as a separate modular device that can be tested independently before final system integration. This segmentation removes barriers to testing by allowing performance validation of the active surface component in isolation, without requiring the complete microfluidic system to be assembled and operational.
