Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple lenses are used for skin detection, then various skin conditions can be detected, but the resolution of reflective skin images deteriorates due to lack of light management
Solution Approach 1:
The patent segments the detection functions by using different light sources (white light LED for general skin imaging, UV LED for metal content detection) and different optical paths (reflective light path with polarizers for surface imaging, transmissive light path for subsurface imaging), allowing each segment to be optimized for its specific function while maintaining overall system versatility
Solution Approach 2:
The patent introduces polarizers as intermediary components in the reflective light path to manage light polarization states, which improves the resolution of reflective skin images by filtering out unwanted reflections and enhancing the contrast of skin surface features
2Adaptability or versatility
If multiple detecting apparatus are used for various skin conditions, then comprehensive skin analysis is achieved, but the device complexity and operational convenience deteriorate
Solution Approach 1:
The patent merges multiple detection functions into a single integrated device by combining white light LED bulbs for general skin imaging, UV LED bulbs for metal content detection, polarizers for reflective light management, and transmissive imaging components, all controlled by a single microcontroller unit that coordinates the different detection modes
Solution Approach 2:
The patent creates a universal skin detection device that can perform multiple functions including surface skin imaging, subsurface skin imaging, metal content detection, and pore analysis through a single apparatus with switchable detection modes, eliminating the need for multiple separate devices

AI summary
The invention provides a skin detection device using different detecting lights, such as white light or UV light. When white light is used, the user's original skin image is acquired, and further analyzed to determine the user's skin condition, such as pore size or dullness of spots. When UV light is used, it is determined whether there is metal remnant or acne on the user's skin. By using the skin detection device, various user skin conditions can be found to help the following cosmetic consultation.
