Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a large number of drones are used to present images in the sky, then image complexity and quality improve, but system cost and coordination complexity increase significantly
Solution Approach 1:
The patent divides the image presentation task into multiple sequential passes by a single drone, where each pass renders one line segment of the image. The system segments the complete image into multiple line segments that can be rendered sequentially, allowing a single drone to create complex images without requiring coordination between multiple drones.
Solution Approach 2:
The patent uses a camera on the drone to capture images of the rendered line segments and transmits these images to a remote device. This creates a digital copy of the sky-written content, allowing the image to be viewed and analyzed on electronic displays without requiring direct visual observation of the sky, thereby improving viewing quality and enabling post-processing.
2Ease of manufacture
If traditional skywriting with airplanes is used, then simple images can be created, but the method requires large airspace and consumes significant fuel
Solution Approach 1:
The patent replaces the traditional mechanical skywriting system (airplane deploying smoke) with an electronic light-based system. A single drone equipped with LED lights emits light signals to create images in the sky, eliminating the need for large amounts of smoke material and reducing fuel consumption by using a smaller, more efficient aerial vehicle.
Solution Approach 2:
The patent uses periodic light signals emitted by the drone to render line segments. The drone flies through specific locations and emits light signals at predetermined times to create visible line segments in the sky. This periodic emission of light allows the drone to create images efficiently without continuous material deployment.
3Ease of operation
If images are created in the sky using traditional methods, then content can be displayed, but images blur or dissipate quickly in strong winds
Solution Approach 1:
The patent captures images of the light-based line segments with a camera on the drone and transmits these digital copies to a remote device. This digital copying process preserves the image content indefinitely, eliminating the problem of wind-blown dissipation that affects physical smoke-based skywriting. The digital image can be viewed and analyzed after the drone has completed its flight.
Solution Approach 2:
The patent uses light signals with different colors or patterns to render line segments in the sky. By using illuminated objects or light-emitting diodes that change color or intensity, the system creates stable, visible markings that are not subject to wind dissipation like smoke, while maintaining the ability to create complex images.
4Device complexity
If a single drone is used to present images, then cost and coordination complexity reduce, but the time required to render complete images increases
Solution Approach 1:
The patent pre-determines the complete set of line segments that make up the image before the drone begins flight. The system calculates the optimal flight path and light signal timing in advance, allowing the drone to efficiently render each line segment in sequence without delays for real-time decision-making or coordination.
Solution Approach 2:
The patent implements continuous flight paths for the drone where each line segment rendering is connected to the next without interruption. The drone maintains continuous motion through the sky, emitting light signals at predetermined locations along its flight path, which minimizes idle time and maximizes the efficiency of image creation by a single drone.

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.
