Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current aircraft cabin illumination systems lack flexibility in configuring color and brightness gradients along the length of lighting units, requiring changes to configuration files and limiting design flexibility when different lighting types are needed for various classes or passenger numbers.
Innovation Solution
A light module with an interface that communicates its characteristics, such as number, position, and color composition of illumination elements, allowing decentralized control and easy exchange, combined with a light-module carrier that supports bidirectional data communication and redundant bus systems for flexible and intelligent illumination control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional centralized control systems with fixed-length lighting units are used, then system stability and centralized control are maintained, but flexibility in configuring cabin illumination and adapting to different cabin layouts is limited
Solution Approach 1:
The lighting system is divided into modular lighting units with standardized interfaces. Each lighting unit can be independently controlled and configured, allowing flexible arrangement in different cabin layouts without requiring system-wide reconfiguration. The segmentation enables adaptive illumination configurations while maintaining manageable system complexity through standardized modules.
Solution Approach 2:
The system employs dynamic configuration capabilities where lighting units can be individually addressed and controlled based on their position and characteristics. The control system adapts to different cabin layouts by receiving position information from each lighting unit and adjusting illumination parameters dynamically, enabling versatility without requiring physical reconfiguration of the entire system.
2Illumination intensity
If lighting unit types are changed to match different cabin classes, then illumination quality is improved, but configuration file updates and system reconfiguration are required
Solution Approach 1:
Each lighting unit is equipped with an interface that automatically provides information about its characteristics and position to the control system. This self-service capability eliminates the need for manual configuration file updates when lighting units are installed or repositioned, as the units self-identify and the control system automatically adapts to the current configuration.
Solution Approach 2:
The system allows dynamic adjustment of illumination parameters such as color temperature, intensity, and timing based on the detected lighting unit characteristics and cabin configuration. This enables different illumination qualities for different cabin classes without requiring physical changes to the lighting hardware or manual reconfiguration of the system.
3Ease of manufacture
If fixed-length lighting units are used, then manufacturing and installation are simplified, but the ability to create color and brightness gradients along the cabin length is limited
Solution Approach 1:
The lighting system uses segmented modular units that can be arranged in sequences to create gradient effects. Each module maintains standardized manufacturing specifications for ease of production, while the modular arrangement enables flexible creation of color and brightness gradients by controlling individual segments along the cabin length.
Solution Approach 2:
The system implements local quality control by enabling independent adjustment of illumination parameters for each lighting unit or segment. This allows creation of smooth color and brightness gradients along the cabin length while maintaining uniform manufacturing standards for each individual module, combining manufacturing simplicity with gradient capability.

AI summary
A light module, a light-module carrier and an illumination system for an aircraft, which allow intelligent illumination and at the same time easy reconfiguration of cabin illumination. The light module provides information relating to its characteristics, while a control system determines a position of the light module on a light-module carrier, and on the basis of the determined position and of the characteristics of the light module adjusts the light module by way of a bus system of the light-module carrier according to a desired illumination.
