Aircraft Lighting Pod Merging Multiple Lights to Cut Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional external lighting systems in aircraft are cumbersome, heavy, and require complex and laborious wiring, which adds significant weight and reduces efficiency in flight.
Innovation Solution
A multifunction lighting pod with an aerodynamic housing that integrates various lights, including taxi, landing, scene, hover, hoist, and searchlights, mounted underneath the aircraft's avionics bay, reducing wiring complexity and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple external lights are deployed throughout the aircraft airframe, then illumination coverage and operational visibility are improved, but aircraft weight increases significantly due to additional lighting components and extensive wiring
Solution Approach 1:
The patent consolidates multiple separate lighting systems (taxi lights, landing lights, scene lights, hover lights, searchlights, and indicator lights) into a single integrated lighting pod assembly. This merging approach maintains comprehensive illumination coverage while dramatically reducing the total weight by eliminating redundant mounting structures, housings, and extensive wiring harnesses that would be required if each light were installed separately throughout the airframe.
Solution Approach 2:
The lighting pod is designed as a multi-functional unit that performs the roles of multiple different lighting systems simultaneously. The single pod contains various types of lights (taxi, landing, scene, hover, search, and indicator lights) that can serve different operational purposes, replacing what would traditionally require multiple separate lighting installations distributed across the aircraft structure.
2Illumination intensity
If multiple lights are installed distributed throughout the aircraft, then comprehensive illumination is achieved, but installation complexity and labor requirements increase
Solution Approach 1:
By combining all lighting functions into a single pre-assembled pod unit, the installation process is simplified from multiple separate installations to one unified mounting operation. The pod arrives as a complete assembly with all lights, wiring, and mounting hardware integrated, requiring only a single attachment point to the aircraft structure rather than multiple distributed installations.
Solution Approach 2:
The lighting pod is pre-assembled and pre-wired as a complete functional unit before installation on the aircraft. All electrical connections, mounting brackets, and light positions are predetermined and configured in advance, eliminating the need for complex on-site wiring and installation work. This preliminary preparation significantly reduces installation time and complexity.
3Weight of moving object
If a single integrated lighting pod is used, then weight and wiring complexity are reduced, but the ability to provide distributed illumination throughout the aircraft is limited
Solution Approach 1:
The lighting pod employs adjustable and movable lighting elements that can direct illumination in multiple directions and angles from a single mounted position. Searchlights with adjustable aim, lights with varying beam patterns, and strategically positioned light sources within the pod create distributed illumination effects throughout the aircraft environment without requiring the pod to be physically distributed across multiple locations.
