Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional light sources like discharge lamps are used for beam systems, then bright and narrow beams with sharp focusing properties can be achieved, but the system cannot utilize LEDs with their advantages of low energy consumption and long lifetime
Solution Approach 1:
The patent divides the light source into multiple independent LED channels (red, green, blue) that can be controlled separately, allowing each LED to operate at optimized levels while collectively producing a bright beam. This segmentation enables LED-specific optimization without compromising overall beam intensity.
Solution Approach 2:
The patent combines multiple colored LED beams into a single unified beam structure, merging the output of red, green, and blue LED channels to create a composite light beam that achieves both the brightness traditionally associated with discharge lamps and the energy efficiency of LEDs.
2Duration of action of stationary object
If LEDs are used in beam systems, then energy consumption is reduced and lifetime is extended, but the ability to produce bright, narrow beams with sharp focusing properties is compromised
Solution Approach 1:
The patent employs dynamic control of the LED channels through independent drivers that can adjust the intensity and color temperature of each LED in real-time. This dynamic adjustment allows the system to optimize between brightness and energy consumption based on operational requirements, while maintaining LED lifetime advantages.
3Adaptability or versatility
If multiple light sources are combined to create multicolored beams, then diverse light effects and mood lighting are achieved, but the beam structure becomes complex and difficult to control
Solution Approach 1:
The patent segments the optical system into distinct red, green, and blue LED channels with dedicated optical elements for each color. This modular segmentation allows independent optimization and control of each color channel, simplifying the overall control architecture while enabling versatile multicolored effects.
Solution Approach 2:
The patent applies different optical characteristics to different color channels, with each LED channel having its own optimized optical path and focusing elements. This local quality approach allows tailored optical performance for each color while maintaining overall system coherence and controllability.
