Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a spectrometer is used for fluid detection, then detection capability is achieved, but the device becomes large, expensive, and difficult to integrate with microfluidic substrates
Solution Approach 1:
The patent combines the spectrometer, light source, and microfluidic substrate into a single integrated device. The spectrometer and light source are mounted on the microfluidic substrate, creating a compact fluid detection panel that maintains detection capability while reducing device size and integration complexity
Solution Approach 2:
The microfluidic substrate serves multiple functions: it acts as both the fluid handling platform and the mounting base for the spectrometer and light source. This multi-functional design reduces the number of separate components needed, simplifying integration while maintaining detection performance
2Measurement precision
If traditional spectrometer detection is used, then detection is possible, but stable light sources and environmental conditions are required, limiting application flexibility
Solution Approach 1:
The patent uses a broadband light source instead of a narrowband laser, changing the spectral parameters to cover a wider range. This allows the system to achieve stable detection across different environmental conditions without requiring precise light source stability, thereby improving adaptability while maintaining detection accuracy
Solution Approach 2:
The system dynamically adjusts to environmental variations by using a broadband spectrum that can adapt to different detection conditions. The wide spectral range allows the device to maintain detection capability across varying temperatures and environmental conditions, enhancing application flexibility
