Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single action spectrum is used to quantify melatonin suppression power, then the measurement process is simplified, but the measurement precision for both short-wavelength and long-wavelength light is compromised
Solution Approach 1:
The patent divides the visible light spectrum into two distinct segments: a first light spectrum for long-wavelength light and a second light spectrum for short-wavelength light. Each segment is processed independently through separate action spectrum generating units, allowing accurate quantification of melatonin suppression power for both wavelength ranges without compromising measurement precision while maintaining manageable processing complexity through modular design.
2Measurement precision
If separate action spectra are generated and integrated for different wavelength ranges, then the measurement precision for both short-wavelength and long-wavelength light is improved, but the device complexity increases
Solution Approach 1:
The processor is segmented into distinct functional units: a first action spectrum generating unit for long-wavelength light and a second action spectrum generating unit for short-wavelength light. This segmentation allows each unit to specialize in processing specific wavelength ranges, improving measurement precision while organizing complexity into manageable, modular components that can be independently optimized.
Solution Approach 2:
The patent merges the results from separate action spectrum generations through a spectrum integrating unit that combines the first action spectrum and second action spectrum into a comprehensive total action spectrum. This merging approach consolidates the benefits of specialized processing for different wavelength ranges into a unified measurement output, achieving high precision without requiring entirely separate measurement systems.
3Adaptability or versatility
If only long-wavelength light spectrum is measured, then the device structure is simplified, but the ability to accurately measure short-wavelength light suppression power is lost
Solution Approach 1:
The spectrum conversion unit is segmented to handle different wavelength ranges separately, with the first light spectrum processing path for long-wavelength light and the second light spectrum processing path for short-wavelength light. This segmentation enables the device to accurately measure both wavelength ranges by directing appropriate spectral components to specialized processing paths, enhancing adaptability while keeping each processing path relatively simple.
Solution Approach 2:
The device achieves multi-functionality by incorporating both first and second action spectrum generating units that can process different wavelength ranges. This universal design allows the same device structure to accurately measure melatonin suppression power across the entire visible spectrum, accommodating various lighting conditions and light sources without requiring multiple specialized devices.
