Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If band pass filters with vapor deposition are used for hemoglobin recognition, then the setup can achieve hemoglobin detection, but the setup becomes complex and recognition efficiency deteriorates
Solution Approach 1:
The patent extracts the hemoglobin recognition function from complex vapor deposition filter systems and implements it using a simple color filter composition with specific absorbance characteristics. The color filter composition selectively absorbs light at hemoglobin's absorption wavelengths (540-580 nm), isolating the detection function from unnecessary system complexity.
Solution Approach 2:
The patent changes the optical parameters of the filter by specifying exact absorbance ratios at different wavelengths (A500/B580 ≥ 2.0, C600/B580 ≥ 1.5). This parameter-based approach replaces complex vapor deposition filtering with a simplified composition that achieves the same hemoglobin detection through controlled light absorption characteristics.

If traditional vapor deposition methods are used, then hemoglobin detection can be performed, but detection accuracy deteriorates
Solution Approach 1:
The patent optimizes detection accuracy by precisely controlling the absorbance parameters of the color filter composition. The specified ratios (A500/B580 ≥ 2.0, C600/B580 ≥ 1.5) ensure maximum contrast at hemoglobin's absorption peaks, significantly improving detection accuracy and recognition efficiency compared to traditional methods.
