Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional biochip detection devices use separate optical components and point-by-point scanning, then detection precision can be maintained, but device size and detection time increase significantly
Solution Approach 1:
The patent integrates the light source, optical path, and image sensor into a single unified detection device. The light source and image sensor are positioned on opposite sides of the biochip, with the optical path passing through the biochip substrate, eliminating the need for separate optical components and reducing device size while maintaining detection precision.
Solution Approach 2:
The detection device is designed to detect multiple specimens simultaneously using a single integrated system. The image sensor captures fluorescence signals from multiple wells in parallel, making the device capable of handling high-throughput screening without requiring multiple separate detection units.
2Device complexity
If conventional devices use point-by-point scanning, then component simplicity is maintained, but detection time becomes excessively long
Solution Approach 1:
The patent replaces the mechanical scanning system with a stationary detection configuration. Instead of moving the detection device or biochip to scan specimens sequentially, the integrated optical system illuminates and detects all specimens simultaneously, eliminating mechanical movement and dramatically reducing detection time.
3Measurement precision
If conventional devices include large optical components and transport mechanisms, then detection accuracy is maintained, but portability and manufacturing cost deteriorate
Solution Approach 1:
The patent segments the detection system into minimal essential components: a light source, a biochip holder, and an image sensor. By eliminating unnecessary optical components and transport mechanisms, the device becomes simpler to manufacture with lower costs while retaining core detection functionality through the integrated optical path design.
