Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If HINS light is used to inactivate microorganisms, then antimicrobial effectiveness is improved, but lighting versatility and color temperature control are limited
Solution Approach 1:
The lighting system is divided into separate HINS LED modules and non-HINS LED modules that can operate independently or together. This segmentation allows the HINS portion to provide antimicrobial effectiveness while the non-HINS portion provides various color temperatures and lighting effects, thus maintaining both antimicrobial reliability and lighting versatility.
Solution Approach 2:
The lighting system achieves multi-functionality by combining HINS LEDs for antimicrobial purposes with non-HINS LEDs for general illumination and color temperature control. The system can serve both as an antimicrobial treatment device and as a conventional lighting system, providing multiple functions through a single integrated platform.
2Reliability
If HINS LEDs are used to provide antimicrobial light, then microorganism inactivation is improved, but overall lighting output and color temperature options are reduced
Solution Approach 1:
The patent merges HINS LEDs and non-HINS LEDs into a single lighting system where both types of LEDs contribute to the overall light output. The non-HINS LEDs compensate for the narrow spectrum and limited visible output of HINS LEDs, providing sufficient illumination while the HINS LEDs maintain their antimicrobial function.
Solution Approach 2:
The system provides multi-functionality by using non-HINS LEDs to deliver general illumination and color temperature control, while HINS LEDs handle antimicrobial treatment. This allows the system to meet both lighting requirements and antimicrobial requirements simultaneously without compromising either function.
3Ease of manufacture
If single-color temperature LEDs are used, then manufacturing simplicity is maintained, but adaptability to different lighting applications is reduced
Solution Approach 1:
The LED array is segmented into HINS LED sections and non-HINS LED sections, each capable of independent control. This segmentation enables the system to produce multiple color temperatures by varying the relative intensities of different LED sections, providing application adaptability while maintaining manufacturing simplicity through modular construction.
Solution Approach 2:
The lighting system implements dynamic control by allowing independent adjustment of HINS and non-HINS LED intensities. This dynamic capability enables the system to adapt to different lighting applications by adjusting color temperature and spectral composition in real-time, transforming a static single-color system into a dynamic multi-mode system.
