Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft exterior lighting systems lack the capability to provide complementary visual information during nighttime parking and rolling phases, especially for pilots and ground personnel, and do not effectively utilize the aircraft's exterior surface for dynamic information projection.
Innovation Solution
A lighting device incorporating a video image projector and a power lighting source, such as LEDs or laser diodes, is mounted on the aircraft to project luminous beams onto exterior surfaces, enabling video mapping and combining luminous fluxes for enhanced visibility and information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional lighting devices are used for aircraft exterior lighting, then the basic lighting and signalling functions are fulfilled, but the capability to provide complementary visual information and dynamic projection is insufficient
Solution Approach 1:
The patent combines a video projector with traditional aircraft lighting devices, merging the projection function with existing lighting infrastructure. This integration allows the system to simultaneously provide traditional lighting/signalling functions and dynamic video projection capabilities, resolving the contradiction between maintaining basic functions and adding information projection capabilities
Solution Approach 2:
The lighting device is designed to perform multiple functions: traditional exterior lighting, signalling, and dynamic video projection. By making the lighting system universal and adaptable to different modes (static lighting and dynamic projection), the system overcomes the limitation of traditional single-function lighting devices
2Loss of information
If a video projector is added to provide dynamic information projection, then the information projection capability is improved, but the device complexity increases
Solution Approach 1:
Instead of adding a completely separate projection system, the patent integrates the video projector within the existing lighting device housing. This merging approach reduces overall system complexity compared to having separate lighting and projection systems, while still achieving enhanced information projection capabilities
Solution Approach 2:
The lighting device is designed as a multi-functional unit that can operate in different modes (traditional lighting and video projection). This universal design allows a single device to replace what would otherwise require multiple separate systems, thereby managing complexity while providing diverse functionality
3Area of stationary object
If multiple lighting sources are integrated in a common housing, then the space utilization is improved, but the luminous flux combination complexity increases
Solution Approach 1:
The patent merges multiple lighting sources (video projector and power lighting lamp) into a single common housing, optimizing space utilization. The housing is designed to accommodate both components and their respective optical paths, reducing the overall footprint compared to separate installations
Solution Approach 2:
A beam combining system acts as an intermediary between the video projector and power lighting lamp, merging their luminous fluxes through optical components. This intermediary mechanism efficiently combines the light paths while maintaining control over the output, managing the complexity of multiple light sources within a compact housing
