Drone Light Signal Imaging for Low-Coordination Sky Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for presenting images in the sky, such as skywriting and drone-based light displays, are either inefficient due to limited maneuverability and high costs, or require complex coordination of large numbers of drones, making them expensive and resource-intensive.
Innovation Solution
A system using a single or multiple drones equipped with navigation and light emitters to create specific light patterns in the sky, which are captured and processed by user devices to identify and present images, optimizing image presentation and reducing the need for extensive airspace and drone coordination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If smoke is deployed by airplanes for skywriting, then simple images can be presented in the sky, but the images require a large amount of airspace and the airplane expends a large amount of fuel
Solution Approach 1:
The patent replaces the mechanical skywriting system (airplane deploying smoke) with an optical system (drones emitting light signals). This substitution eliminates the need for large airspace maneuvers and reduces energy consumption by using efficient LED emitters instead of fuel-intensive airplane flight and smoke deployment
Solution Approach 2:
The patent changes the fundamental parameters of image presentation by transitioning from physical smoke trails requiring large spatial dimensions to concentrated light signals that can be precisely positioned. This parameter change allows images to be created with minimal airspace and reduced energy expenditure
2Adaptability or versatility
If a large number of drones are used to present images with light projections, then text and images can be displayed in the sky, but the systems are very expensive and require complex coordination software
Solution Approach 1:
The patent divides the image presentation task into discrete light signal emissions at specific sky locations rather than requiring coordinated flight of multiple drones. Each light signal represents a segment of the final image, and these segments are compiled by user devices to reconstruct the complete image, eliminating complex inter-drone coordination
Solution Approach 2:
The patent creates a digital copy of the sky-based light signals through user device capture and processing. Instead of requiring direct observation of the physical light patterns in the sky, the system captures images with user devices and processes them to present the final image display, simplifying the coordination requirements
3Ease of manufacture
If traditional skywriting is used to present images, then simple text and symbols can be displayed, but the images may blur or dissipate quickly in strong winds
Solution Approach 1:
The patent replaces the smoke-based mechanical skywriting system with an optical light signal system emitted by drones. Light signals are not subject to wind dissipation like smoke, providing reliable and stable image presentation regardless of weather conditions while maintaining ease of image creation
Solution Approach 2:
The patent changes the physical state of the image medium from gaseous smoke (vulnerable to wind) to electromagnetic light signals (immune to wind). This parameter change fundamentally improves image stability and reliability while preserving the simplicity of image creation through programmed light emissions

Function Achieved in This Case
This approach allows for efficient and cost-effective presentation of images in the sky by using drones to emit light signals that can be accurately captured and processed by user devices, providing clear and stable image rendering without the need for large numbers of drones or extensive airspace.

Data Source
AI summary
Systems, devices, and methods for presenting information in the sky using drones are disclosed. The presentation of information includes navigating one or more drones to locations in the sky where the locations are associated with an image, emitting light signals at the locations, capturing the light signals with a user device, processing the captured signals to identify the image, capturing a background image including at least one of the locations associated with the image, and presenting simultaneously, on the user device, the identified image and the background image.
