Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional artificial lighting (filament lamp, fluorescent lamp, sodium lamp, high pressure mercury lamp) is used for plant tissue culture, then the lighting can be provided continuously, but the emission spectrum cannot satisfy selective light absorption requirements, leading to low photosynthesis efficiency and high energy consumption
Solution Approach 1:
The patent changes the spectral parameters of the lighting system by using LEDs with specific wavelengths (red: 630nm, blue: 460nm) that match the absorption spectrum of plants, replacing traditional broad-spectrum or mismatched spectrum lighting sources to achieve resonant absorption and high photosynthesis efficiency
Solution Approach 2:
The patent combines multiple LED types (red and blue LEDs) in a composite lighting system where red LEDs provide 630nm light for chlorophyll absorption and blue LEDs provide 460nm light for additional photosynthetic activity, creating a synergistic effect that enhances overall photosynthesis efficiency compared to single-wavelength or traditional lighting
2Duration of action of stationary object
If fluorescent lamp is used for artificial lighting, then the light can be provided, but the service life is short and heat productivity is high requiring extra electricity, leading to high power consumption cost
Solution Approach 1:
The patent replaces the fluorescent lighting system with LED technology, substituting the mechanical/electrical processes of fluorescent lamps with the electroluminescence process of LEDs, which converts electrical energy directly to light without the heat generation and short service life issues of fluorescent technology
Solution Approach 2:
The patent changes the operational parameters of the lighting system by using LEDs that operate at lower temperatures and have longer service lives compared to fluorescent lamps, while maintaining or improving light output efficiency and reducing energy consumption
3Productivity
If LED lighting with specific wavelength arrangement is used, then photosynthesis efficiency is improved, but the device complexity increases due to specific arrangement requirements
Solution Approach 1:
The patent divides the lighting system into modular units, each containing a specific arrangement of red and blue LEDs, allowing for standardized production and easy installation while maintaining the complex spectral composition needed for high photosynthesis efficiency
Solution Approach 2:
The patent designs a universal LED lighting module that can be applied to different plant types and growth stages by adjusting the intensity ratios of red and blue LEDs, making the system adaptable to various tissue culture requirements without requiring completely different lighting configurations
