Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If violet light sources are used for sanification function, then sanification capacity is improved, but additional light sources are required to compensate for emission and provide suitable white light for ambient lighting
Solution Approach 1:
The patent employs a single LED light source that simultaneously performs multiple functions: ambient lighting and sanification. By selecting an LED with peak wavelength between 470-480nm, the system achieves both adequate white light output for lighting and sufficient violet spectrum emission for killing pathogenic microorganisms, thereby eliminating the need for separate sanification light sources.
Solution Approach 2:
The invention merges the ambient lighting function and sanification function into a single integrated light source. Instead of using separate LEDs for lighting and sanification, the patent combines both functions into one LED emitter, simplifying the device structure while maintaining effectiveness of both functions.
2Illumination intensity
If normal lighting apparatuses are used, then ambient lighting is provided, but they are not suitable for plant maintenance and well-being in indoor environments
Solution Approach 1:
The patent optimizes the spectral parameters of the LED light source to simultaneously satisfy human lighting needs and plant maintenance requirements. By selecting LEDs with peak wavelengths between 470-480nm and controlling color temperature between 6500-10000K, the system provides appropriate illumination for both human comfort and plant photosynthesis in indoor environments.
3Adaptability or versatility
If multiple light sources are used to achieve different functions, then functionality is improved, but device complexity and dimensions increase
Solution Approach 1:
The patent implements a universal light source that delivers multiple functions including ambient lighting, sanification against pathogenic microorganisms, and plant maintenance support. This single LED-based solution eliminates the need for multiple separate light sources, thereby maintaining high functionality while ensuring construction simplicity.
4Adaptability or versatility
If multiple light sources are used to provide different lighting modes, then versatility is improved, but device dimensions increase
Solution Approach 1:
The invention combines multiple lighting modes (ambient lighting, sanification mode, plant maintenance mode) into a single integrated LED light source. This approach maintains the versatility of offering different functional modes while keeping the device compact, as no additional light sources or separate modules are required.
