Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing use of multicopters for various purposes poses challenges to flight safety, particularly in terms of collision avoidance and air space awareness, as existing technologies lack effective methods for visually indicating the flight direction of these agile and rapidly changing aerial vehicles.
Innovation Solution
A method and system utilizing a matrix of light sources, such as LEDs, mounted on the aerial vehicle to provide an illumination pattern that indicates its flight direction to observers, enhancing visibility and awareness of the vehicle's path, thereby reducing the risk of collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no flight direction indication system is used, then the device complexity is low, but the flight safety and air space awareness deteriorate
Solution Approach 1:
The patent uses different colors of light sources (e.g., red, green, blue LEDs) to indicate different flight directions and states. The illumination pattern changes color to communicate vertical movement (ascend/descend) and horizontal direction, making the flight status intuitively recognizable to observers without requiring complex display mechanisms
Solution Approach 2:
The flight direction indication system is segmented into multiple independent light sources arranged in a matrix pattern on the aerial vehicle. Each light source can be independently controlled to create different illumination patterns, allowing compact representation of multiple flight parameters (direction, velocity, status) without requiring a single complex indication device
2Loss of information
If a flight direction indication system is added, then the air space awareness improves, but the device complexity increases
Solution Approach 1:
The illumination pattern system serves multiple functions simultaneously: it indicates flight direction, vertical movement status, horizontal position, and operational state (e.g., landing, taking off). This multi-functionality reduces the need for separate indication systems for each parameter, minimizing overall device complexity while maximizing information delivery
Solution Approach 2:
The light sources act as an intermediary between the aerial vehicle's flight control system and external observers. Rather than requiring direct communication or complex sensors, the system translates flight parameters into intuitive visual patterns that observers can immediately understand, effectively mediating the information transfer with minimal complexity
3Loss of information
If multiple light sources are used to indicate flight direction, then the information about flight path improves, but the use of energy increases
Solution Approach 1:
The system activates only the necessary subset of light sources based on the current flight state, rather than illuminating all lights continuously. For example, only the lights corresponding to the current flight direction and status are activated, reducing energy consumption while maintaining complete information about the flight path
Solution Approach 2:
The illumination pattern can be activated periodically or in response to specific flight events rather than continuously. The system may pulse lights during critical maneuvers or only activate when the aerial vehicle is in motion, reducing overall energy usage while ensuring information is available when most needed
