Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate hole is added in the rear surface for light detection, then light source and illuminance detection capability is improved, but device structure complexity and manufacturing difficulty increase
Solution Approach 1:
The optical sensor module serves multiple functions: it detects light sources, measures illuminance, and enables ambient light sensing, all through a single integrated component structure. This multi-functional approach eliminates the need for separate detection holes while maintaining comprehensive light detection capabilities
Solution Approach 2:
The patent combines the light receiving elements, filters, and optical components into a single integrated optical sensor module that is embedded within the existing housing structure. This merging of components eliminates the need for additional separate holes in the rear surface, reducing structural complexity while maintaining detection functionality
2Measurement precision
If multiple light receiving elements with different filters are used, then light source type detection accuracy is improved, but sensor module complexity increases
Solution Approach 1:
The optical sensor module is segmented into multiple light receiving elements, each equipped with specific wavelength filters. This segmentation allows each element to detect specific wavelength ranges, enabling accurate light source type identification through spectral analysis while maintaining a compact integrated structure
Solution Approach 2:
Different regions of the optical sensor module are assigned different filtering characteristics tailored to specific detection needs. Each light receiving element has locally optimized filter properties matched to its detection function, enabling precise light source identification without requiring complex centralized processing
