Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If fluorescent lamps are used for area lighting, then they can provide illumination, but they cause environmental mercury contamination and are sensitive to temperature changes
Solution Approach 1:
The patent removes the harmful mercury component from the lighting system by using LED technology instead of fluorescent lamps. The LED module directly converts electrical energy to light without requiring mercury vapor, thereby eliminating the contamination risk while maintaining illumination functionality.
Solution Approach 2:
The patent changes the operating parameters by using LEDs that are not sensitive to temperature fluctuations like fluorescent lamps. The LED lighting system maintains stable performance across a wider temperature range, eliminating the temperature sensitivity issue while providing continuous illumination.
2Illumination intensity
If early LEDs are used for lighting, then they can emit light, but they were costly and limited to red light emission
Solution Approach 1:
The patent employs composite LED structures with multiple LED modules emitting different wavelengths (red, green, blue) that combine to produce white light. This composite approach enables full-spectrum illumination while maintaining the cost-effectiveness and efficiency of LED technology.
Solution Approach 2:
The patent creates a universal lighting solution by integrating multiple LED modules with different emission characteristics into a single system. The LED lighting apparatus can provide various light spectra and colors through different module combinations, making it versatile for multiple lighting applications.
3Illumination intensity
If conventional lighting systems are used, then they can provide illumination, but they have limited illuminance range
Solution Approach 1:
The patent divides the lighting system into multiple LED modules positioned at different orientations and locations. This segmentation allows each module to illuminate specific zones, and collectively they cover a much larger area than a single conventional lamp, extending the illuminance range throughout the space.
Solution Approach 2:
The patent adds spatial dimensionality to lighting by positioning LED modules at multiple angles and heights. The light sources are arranged to illuminate not only the immediate area but also reflect off surfaces to cover adjacent areas, effectively expanding the lighting coverage in three-dimensional space.
4Illumination intensity
If fluorescent lamps are used, then they can illuminate areas, but they produce buzzing noise and radio frequency interference
Solution Approach 1:
The patent replaces the electromagnetic ballast system of fluorescent lamps with a direct LED driving circuit. This substitution eliminates the electromagnetic components that generate buzzing noise and radio frequency interference, while LED technology provides illumination through a simpler, quieter electrical-to-optical conversion process.
