Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional atmosphere lights are used, then simple lighting effects are achieved, but the capability to display panoramic patterns of the universe is lacking
Solution Approach 1:
The device is divided into multiple independent functional units: a constellation unit with DOE grating combination disk for constellation patterns, a planetary unit with replaceable planetary patterns, and a background unit with transmission disk for aurora and cloud effects. Each unit can independently project specific celestial patterns, allowing comprehensive cosmic display while maintaining modular simplicity.
Solution Approach 2:
The device integrates multiple functions into a single system that can display various celestial patterns including constellations, planets, auroras, and starry skies. The beam splitter enables the laser generator to serve multiple purposes by directing light to different DOE gratings and optical components, creating a universal atmosphere light for diverse festival entertainment scenarios.
2Adaptability or versatility
If single-function atmosphere lights are used, then device simplicity is maintained, but the ability to switch between different celestial displays is limited
Solution Approach 1:
The device incorporates dynamic switching capabilities through the beam splitter that can direct laser light to different DOE grating combination disks, enabling real-time switching between constellation patterns, planetary patterns, and background effects. The replaceable planetary patterns and rotatable transmission disk add dynamic elements that allow versatile display changes without complicating the overall operation.
3Manufacturing precision
If conventional projection methods are used, then basic lighting is achieved, but projection definition and large-angle coverage are insufficient
Solution Approach 1:
The device replaces conventional mechanical projection systems with optical field-based methods using DOE (diffractive optical element) gratings and beam splitters. This substitution enables precise pattern formation through light diffraction and interference, achieving high projection definition and large-angle coverage while maintaining elegant optical simplicity.
