Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional incandescent or gas discharge lamps are used as light sources, then the lighting system can provide sufficient illumination, but the power consumption is high and heat generation is excessive
Solution Approach 1:
The patent transitions from conventional incandescent or gas discharge lamps to LED technology, fundamentally changing the light generation mechanism. This parameter change enables significantly lower power consumption and heat generation while maintaining or improving illumination effectiveness, directly resolving the contradiction between lighting effectiveness and energy usage
2Illumination intensity
If conventional light sources are used, then sufficient lighting can be achieved, but the service life is limited and maintenance is required
Solution Approach 1:
The patent employs LED technology which fundamentally changes the operational characteristics of the light source. LEDs provide significantly extended service life compared to conventional lamps, reducing maintenance requirements while delivering effective illumination, thus resolving the contradiction between lighting effectiveness and service life
3Illumination intensity
If conventional light sources are used, then illumination can be provided, but heat generation is excessive requiring larger heat sinks
Solution Approach 1:
The patent transitions to LED technology which fundamentally alters the thermal characteristics of the lighting system. LEDs generate significantly less heat compared to conventional incandescent or gas discharge lamps, reducing thermal management requirements and enabling more compact designs while maintaining effective illumination
4Area of stationary object
If multiple individual LEDs are used instead of COB LED, then the lighting area can be larger, but the structure becomes more complex and space-consuming
Solution Approach 1:
The patent employs COB (Chip on Board) LED technology which merges multiple individual LED chips onto a single substrate. This integration achieves a compact, space-saving structure with reduced complexity while maintaining or enhancing the lighting area, directly resolving the contradiction between lighting area and structural complexity
