Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed illumination configuration is used in existing lighting apparatuses, then the structure is simple and reliable, but the adaptability and flexibility are poor
Solution Approach 1:
The lighting apparatus divides the illumination function into multiple independent laser light modification units positioned at different locations. Each unit can be independently controlled to modify optical characteristics, allowing flexible reconfiguration of illumination patterns without redesigning the entire system.
Solution Approach 2:
The system employs dynamic control of laser light distribution through modulation units that can change the illumination configuration in real-time. The laser light distribution modification unit enables dynamic switching between different illumination modes and patterns, transforming a static system into a dynamically adaptable one.
2Use of energy by moving object
If laser light is directed over large distances, then the energy density is high and transmission efficiency is good, but the beam position sensitivity increases making precise control difficult
Solution Approach 1:
The patent introduces laser light modification units as intermediary components between the laser source and the final illumination target. These units include optical elements that can focus, diffuse, or shape the laser beam, serving as mediators that maintain energy density while enabling precise positional control through controlled beam manipulation.
Solution Approach 2:
The system replaces mechanical beam positioning mechanisms with optical field control methods. By using optical elements and field-based modulation rather than physical movement, the system maintains high energy density transmission over large distances while achieving precise control through optical field manipulation rather than mechanical adjustment.
