Engineering Contradiction Analysis
1Illumination intensity
If conventional LED-based signaling devices use sophisticated collimators and light projection systems to achieve sufficient light intensity for aerial signaling, then the light intensity is sufficient (2000-20000 candelas), but the device becomes bulky and complex
Solution Approach 1:
The patent changes the light source from conventional LEDs to laser diodes, which inherently emit more directional and intense light. This parameter change in the light source characteristics eliminates the need for complex collimators and projection systems, achieving the required 2000-20000 candelas intensity with a much simpler device structure
Solution Approach 2:
The patent extracts and removes the complex collimator and light projection systems from the conventional LED-based signaling device. By using laser diodes that naturally provide directional emission, the patent eliminates these unnecessary components, achieving the same light intensity function with a simplified structure
