Air Mobility Lighting System for Propeller Warning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The safety concerns associated with air mobility devices, such as hoverboards and electric kickboards, arise from the potential for propeller rotations to cause personal injury and generate strong winds, necessitating a warning system to alert individuals in the vicinity.
Innovation Solution
A lighting system integrated with air mobility devices, featuring a light emitting unit on a boom or propeller that projects light onto the ground surface to indicate the device's operational modes, including a circular shape, warning messages, and brand logos, controlled by a unit that adjusts based on the device's operating modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a warning system is added to alert individuals of propeller rotation dangers, then safety is improved, but device complexity increases
Solution Approach 1:
The lighting system merges the warning function with the propeller assembly itself by mounting light emitting units directly on the boom or propeller structure. This integration eliminates the need for separate warning devices while providing effective safety alerts through projected light patterns that indicate propeller rotation status and operational modes.
Solution Approach 2:
The light emitting unit serves multiple functions: it warns of propeller rotation dangers, indicates operational modes (standby, driving, landing), provides brand recognition through logos, and guides occupants to boarding doors. This multi-functionality reduces the need for multiple separate systems while improving overall safety and user experience.
2Loss of information
If multiple light emitting units are installed to provide comprehensive warnings and information, then information effectiveness is improved, but device complexity increases
Solution Approach 1:
The lighting system divides the warning and information function into multiple light emitting units positioned at different locations (boom, propeller, lower end portion). Each unit can be independently controlled to provide specific information, allowing comprehensive coverage without requiring a single complex system. The segmentation enables targeted information delivery to different observation points.
Solution Approach 2:
The system transitions from single-point light emission to multi-dimensional light projection by directing light toward the ground surface from multiple positions. This creates spatially distributed light patterns (circles, rings, messages) that provide comprehensive information from various angles and distances, enhancing information effectiveness without proportionally increasing complexity.
3Reliability
If the light emitting unit projects light patterns to indicate operational modes, then safety information is improved, but energy consumption increases
Solution Approach 1:
The control unit manages light emission in periodic patterns corresponding to operational modes (standby, driving, landing). The light emitting units are activated only when needed to convey specific operational information, rather than operating continuously. This periodic activation reduces energy consumption while maintaining effective safety communication throughout the air mobility device's operational cycle.

AI summary
A lighting system for air mobility may include a light emitting unit provided on a boom or a propeller of the air mobility and configured to emit light toward a ground surface so that the light is projected onto a point directed toward the ground surface from the propeller or the boom; and a control unit electrically connected to the light emitting unit and configured to control light emitting modes of the light, emitted by the light emitting unit, based on operating modes of the air mobility or operating modes of the propeller.
