Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional face masks use uniform distribution of irradiation sources, then the device structure is simple, but the therapeutic effectiveness for different facial regions is insufficient
Solution Approach 1:
The patent applies local quality by creating different irradiation zones with specific wavelength distributions tailored to different facial regions. The control module enables selective activation of irradiation sources at different wavelengths (red, infrared, deep red, green, yellow) for specific zones, allowing each facial region to receive customized irradiation based on its therapeutic needs, thereby improving therapeutic effectiveness without requiring complete redesign of the entire device structure
2Adaptability or versatility
If the device operates in only two modes (all sources simultaneous or alternating red/infrared), then the device complexity is low, but the versatility for different therapeutic applications is limited
Solution Approach 1:
The patent implements dynamics by providing a control module that enables multiple operating modes beyond the conventional two modes. The control module can selectively activate different combinations of irradiation sources at various wavelengths and patterns, allowing dynamic adaptation to different therapeutic requirements. This includes simultaneous multi-wavelength activation, sequential activation, and customized treatment protocols, thereby significantly enhancing versatility while maintaining manageable device complexity through systematic control
3Adaptability or versatility
If only red and infrared LEDs are used, then the device structure is simple, but the range of therapeutic wavelengths is insufficient
Solution Approach 1:
The patent applies universality by incorporating multiple types of irradiation sources (red LEDs, infrared LEDs, deep red LEDs, green LEDs, yellow LEDs) into a single facial mask device. This multi-functional approach allows the device to address various skin conditions and therapeutic needs through different wavelength combinations, making one device capable of performing multiple therapeutic functions that would otherwise require separate devices, thereby expanding wavelength coverage without proportionally increasing device complexity
