Rotating Drone LED Ring for Sound-Reactive Air Writing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-controlled drones lack the capability to create the effect of writing words in the air using a combination of LED lights in a cycling motion that is reactive to sound, primarily used for nighttime displays against a dark sky, as they typically only turn lights on or off for mimic independent movement.
Innovation Solution
A remote-controlled drone equipped with a software algorithm and a rotating LED lighting ring that can move independently of the drone, reacting to sound or other stimuli, creating the illusion of writing shapes or words in the air by using a drone frame, motors, a LED microcontroller, and wireless communication to control the LED lights and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If LED lights are turned on or off to mimic independent movement, then the device structure is simple, but the visual effect and entertainment value are limited
Solution Approach 1:
The patent implements independent motion control of the LED ring relative to the drone body, allowing the lighting apparatus to rotate and move independently while the drone flies. This dynamic separation enables complex visual patterns and persistence of vision effects without requiring the entire drone structure to be complex, resolving the contradiction between simple device structure and versatile visual effects.
Solution Approach 2:
The lighting system is segmented from the main drone body as an independent rotating ring module. This segmentation allows the LED ring to perform independent rotational movements controlled by separate motors, enabling diverse visual displays while keeping the overall drone structure relatively simple and modular.
2Illumination intensity
If LED lights are used to create persistence of vision effect, then the visual display effect is enhanced, but the drone becomes invisible which may reduce safety awareness
Solution Approach 1:
The LED lights are activated in periodic sequences during specific phases of the rotating ring's rotation, creating persistence of vision effects that form visible patterns in the air. The lights are not continuously on but rather flash at strategically timed intervals, enhancing visual display while maintaining some visibility awareness through the periodic nature of the illumination.
3Adaptability or versatility
If the LED housing moves independently around the drone axis, then the persistence of vision effect is achieved, but the device complexity increases due to additional motors and bearings
Solution Approach 1:
The rotating LED ring structure serves multiple functions: it acts as both the lighting apparatus and the rotating mechanism, with the same structural components serving both support and rotational movement purposes. This multi-functionality reduces the need for separate dedicated structures, offsetting the added complexity of independent motion capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The drone achieves a persistence of vision effect, making the drone itself invisible under low light conditions, providing a visually stimulating display by independently moving LED lights that can be programmed or react to external stimuli, enhancing nighttime displays.
Implementation Method 1
the at least one LED light creates a persistence of vision such that the drone is invisible in relation to the at least one LED light
Data Source
AI summary
There is a remote control device or drone, which has software and a combination of lights or LED on an lighting ring or apparatus that can move independently of the drone; the drone can be programmed or be reactive to sound or other stimulus to create the effect of writing shapes or words in the air and typically at nighttime against a dark sky.
