Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If microfluidics technology is used for lab on a chip, then sample processing can be completed on a single chip, but the device lacks integration of essential components like micro pumps and fluid platforms, limiting operational convenience and efficiency
Solution Approach 1:
The patent integrates the micro pump, fluid platform, and control circuitry onto a single substrate to form a complete lab-on-a-chip system. This merging of previously separate components enables sample processing to be completed on one chip while maintaining full operational functionality, directly resolving the contradiction between device integration and operational convenience
