Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple LEDs with different wavelengths are used to analyze different constituents in milk, then the analysis capability for multiple constituents is improved, but the device complexity and cost increase
Solution Approach 1:
The patent employs a single LED that emits multiple wavelengths simultaneously to perform spectroscopic analysis of multiple milk constituents (fat, protein, lactose, contaminants) without requiring multiple separate LEDs or wavelength-specific components. This universal approach allows one light source to serve multiple analytical functions, reducing device complexity while maintaining comprehensive analysis capability
Solution Approach 2:
The patent merges multiple wavelength analyses into a single simultaneous measurement process. Instead of sequentially switching between multiple LEDs for different wavelength ranges, the invention combines all necessary wavelength information from a single LED source into one integrated spectroscopic measurement, thereby simplifying the device architecture and reducing component count

3Measurement precision
If laboratory examination is used to analyze multiple constituents in milk, then the analysis accuracy is improved, but the time consumption and productivity decrease
Solution Approach 1:
The patent replaces complex mechanical laboratory examination systems with a simplified optical spectroscopic system using a single LED and sensor. This substitution maintains measurement precision for multiple constituents (fat, protein, lactose, contaminants) while enabling rapid real-time analysis directly in the milking system, eliminating time-consuming sample collection, transport, and laboratory processing steps
Solution Approach 2:
The patent performs preliminary spectroscopic analysis directly at the milking location before milk is processed or discarded. By conducting the analysis in advance at the source, the system enables immediate identification of contaminated milk or quality issues, allowing for real-time decision-making and segregation without waiting for subsequent laboratory examination results
