Exterior Helicopter Light Color-Coded Ground Sectors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passengers and ground personnel face risks of accidents while approaching helicopters due to forgotten or ignored safety instructions, especially in stressful situations like rescue operations, as existing safety measures are inadequate in clearly indicating safe and dangerous areas around the aircraft.
Innovation Solution
An exterior helicopter light system is mounted on the helicopter, emitting different colored lights to clearly indicate safe and dangerous areas on the ground, with specific color codes for the rear, forward, lateral, and intermediate sectors, providing a visual aid to guide personnel safely around the aircraft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If safety instructions are provided to passengers and ground personnel, then awareness of dangerous areas is improved, but compliance and retention of safety information deteriorates in stressful situations
Solution Approach 1:
The patent applies color-coded lighting to visually indicate safe and dangerous areas around the helicopter. Different colors (e.g., green for safe, red for dangerous) are emitted by light sources positioned at different locations on the helicopter to create an intuitive visual guide that remains effective even in stressful situations where verbal instructions may be forgotten or ignored.
Solution Approach 2:
The patent introduces a visual intermediary system (colored lights) that mediates between the helicopter and ground personnel. This intermediary provides continuous, passive visual information about safe approach areas without requiring active communication or reliance on human memory, thereby improving compliance reliability.
2Loss of information
If multiple light sources with different colors are used to indicate safe and dangerous areas, then visual guidance effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent segments the ground area around the helicopter into distinct zones (safe and dangerous areas) and assigns different color codes to each zone. This segmentation allows ground personnel to quickly identify appropriate approach areas without requiring complex interpretation, while the system itself uses multiple independent light sources that can be controlled separately.
Solution Approach 2:
The patent employs light sources that can serve multiple functions: they indicate both the presence of dangerous areas and the location of safe approach areas simultaneously through different colors. This multi-functionality reduces the need for separate signaling systems while maintaining clear visual guidance.
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 system significantly enhances safety by clearly marking safe approaches and avoiding dangerous areas, reducing the risk of accidents even in stressful situations by providing a visual aid that is intuitive and easy to follow.
Implementation Method 1
The light sources of the first set are configured for emitting, in operation, light of a first color into at least one rear sector of a ground below the helicopter
Data Source
AI summary
An exterior helicopter light is configured to be mounted to a helicopter, in particular to an underside of the helicopter, the helicopter having a longitudinal axis (A). The exterior helicopter light comprises: a first set of light sources configured for emitting, in operation, light of a first color into a at least one rear sector of a ground below the helicopter, the at least one rear sector spatially extending around a projection of a rear portion of the helicopter onto the ground; and second set of light sources configured for emitting, in operation, light of a second color, which differs from the first color, into at least two forward sectors of the ground below the helicopter.
