Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light show technologies using unmanned aerial vehicles (UAVs) face challenges with flat, two-dimensional displays that are difficult to maintain in windy or indoor air current environments and lack high contrast, necessitating a stable and dynamic three-dimensional screening medium.
Innovation Solution
A system comprising UAVs with a screening medium reservoir, a Ground Control Station (GCS) for flight control, and a light controller for synchronizing light source control, using pressurized water or aerosol ejectors to create a three-dimensional screen that can withstand weather conditions and maintain shape throughout the show.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If large reflective screens are used for light show, then the light show can be displayed, but the screens are very difficult to quickly position and retain in the desired position for a long time
Solution Approach 1:
The patent replaces the mechanical reflective screen system with a volumetric display system using laser projection onto particles suspended in air. This substitution eliminates the need for physical screens that require mechanical positioning, while achieving stable and maintainable light show displays through controlled particle suspension and laser projection.
2Shape
If traditional screens are used for light show, then the display can be created, but the light show pictures are flat and not three-dimensional
Solution Approach 1:
The patent transitions from two-dimensional flat screens to three-dimensional volumetric displays by projecting laser light onto particles suspended in three-dimensional space. This creates genuine 3D light show pictures that can be viewed from multiple angles, achieving dimensional enhancement through spatial particle distribution and laser projection geometry.
3Stability of the object's composition
If smoke or gas sprayers are used to create three-dimensional panorama screens, then three-dimensional display is achieved, but the screens can quickly dissolve in the air and can also be quickly blown away by the wind
Solution Approach 1:
The patent changes the physical parameters of the screening medium from smoke or gas to fine particles suspended in air, which can be generated by aerosol ejectors or pressurized water systems. This parameter change provides better stability against wind and dissolution while maintaining ease of creation through controlled particle generation and suspension mechanisms.
4Illumination intensity
If a heterogeneous screening medium is used to withstand weather conditions, then the light show contrast and vibrancy improve, but the environmental impact and human health impact increase
Solution Approach 1:
The patent uses fine particles as the screening medium that provide sufficient contrast and vibrancy for the light show while having minimal environmental impact and human health impact. The local quality of the particles is optimized to achieve the required optical properties without requiring harmful heterogeneous materials, balancing display quality with environmental safety.
