Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional microchip solution sending systems operate at low flow rates, then the system complexity remains manageable, but the reaction efficiency is low and detection accuracy is poor
Solution Approach 1:
The patent applies parameter changes by increasing the flow rate from conventional low rates to 1,000-50,000 μl/min, which transforms the reaction dynamics and improves both reaction efficiency and detection accuracy simultaneously. This parameter change resolves the contradiction by finding an optimal flow rate range that enhances productivity without sacrificing measurement precision.
2Reliability
If conventional systems use low flow rates, then energy consumption is reduced, but significant dispersion in reaction amounts occurs between individual systems
Solution Approach 1:
The patent resolves this contradiction by changing the flow rate parameter to 1,000-50,000 μl/min, which reduces dispersion in reaction amounts between individual systems. The increased flow rate ensures more consistent and reproducible reactions across multiple systems, and the energy consumption increase is acceptable given the significant improvement in reliability and consistency.
3Productivity
If the flow rate is increased to improve reaction efficiency, then the reaction amount increases, but the flow passage design becomes more complex
Solution Approach 1:
The patent resolves this contradiction primarily through parameter changes (flow rate optimization) rather than complex structural modifications. By optimizing the flow rate to 1,000-50,000 μl/min, the system achieves high reaction efficiency using relatively simple flow passage designs, avoiding the need for complex structural solutions.
