Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED lighting is used for illumination, then energy efficiency and lifetime are improved, but sterilization function is not provided
Solution Approach 1:
The patent combines LED illumination sources with UV-LED sterilization sources into a single lighting apparatus. The housing contains both the visible LED light source and the UV-LED sterilization source, allowing the device to perform both illumination and sterilization functions simultaneously, thereby resolving the contradiction between energy-efficient illumination and sterilization capability.
Solution Approach 2:
The lighting apparatus is designed with multi-functionality to provide both illumination and sterilization capabilities. The driver circuit can selectively activate either the LED light source or the UV-LED sterilization source based on operational mode, enabling the single device to serve multiple purposes: general lighting, sterilization, and potentially circadian rhythm regulation.
2Adaptability or versatility
If UV light is added for sterilization, then sterilization capability is improved, but harmful effects on human body increase
Solution Approach 1:
The patent introduces a controllable driver circuit as an intermediary between the UV-LED sterilization source and the user environment. This driver circuit can selectively activate the UV-LED only when sterilization mode is engaged and can control the intensity and duration of UV exposure, thereby mediating the potential harmful effects while maintaining sterilization capability.
Solution Approach 2:
The lighting apparatus incorporates sensors that detect environmental conditions and user presence. These sensors provide feedback to the driver circuit, which can then modulate or deactivate the UV-LED sterilization source when human presence is detected, preventing harmful exposure while maintaining sterilization functionality when safe.
3Adaptability or versatility
If multiple light sources are integrated, then functionality is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple light sources (LED illumination and UV-LED sterilization) into a single integrated housing with a unified driver circuit. This consolidation approach provides multiple functions while minimizing the increase in device complexity by sharing structural and control components rather than creating separate independent systems.
4Reliability
If LED cost was high in early stage, then technology先进性 was improved, but affordability decreased
Solution Approach 1:
The patent combines high-technology UV-LED sterilization sources with cost-effective LED illumination sources in an integrated design. This merging allows the apparatus to leverage the advanced sterilization capability of UV-LEDs while using more affordable LED components for general illumination, thereby maintaining technological先进性 while improving affordability.
