Aircraft Seat Display Brightness Control for Cohesive Cabin Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aircraft lighting systems fail to create a cohesive ambience light between interior cabin lighting, in-seat lighting, and IFE display lighting, often operating independently and lacking dynamic adjustment based on cabin conditions.
Innovation Solution
Integrating light sensors with in-flight entertainment systems to determine cabin lighting conditions, using a group of monitors to measure light data, and a light control module to adjust brightness levels automatically based on ambient light changes, eliminating manual control schedules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional independent lighting systems are used for interior cabin lighting, in-seat lighting, and IFE display lighting, then each lighting system can be controlled separately, but they fail to create a cohesive ambience light and require multiple manual control schedules
Solution Approach 1:
The patent combines interior cabin lighting, in-seat lighting, and IFE display lighting into a unified lighting management system. The controller receives ambient light sensor data and coordinates all three lighting types simultaneously to create cohesive ambience, replacing the conventional approach of separate independent control systems with integrated management.
Solution Approach 2:
The unified lighting management system serves multiple functions: it controls interior cabin lighting, in-seat lighting, and IFE display lighting through a single controller that responds to ambient light conditions. This multi-functional system eliminates the need for multiple separate control schedules while maintaining cohesive ambience across all lighting zones.
2Adaptability or versatility
If manual control schedules are used for adjusting lighting brightness, then the system is simple to implement, but it lacks dynamic adjustment capability based on real-time cabin conditions
Solution Approach 1:
The system incorporates ambient light sensors that continuously monitor cabin lighting conditions and feed this data back to the controller. The controller dynamically adjusts the brightness of interior cabin lighting, in-seat lighting, and IFE display lighting based on real-time sensor input, enabling automatic adaptation to changing ambient conditions without manual intervention.
Solution Approach 2:
The lighting management system operates autonomously by using ambient light sensor data to automatically adjust brightness levels. The controller self-regulates all lighting zones based on predefined thresholds and ambient conditions, eliminating the need for manual control schedules while providing continuous dynamic adjustment capability.
3Object-affected harmful factors
If fixed brightness levels are maintained for IFE display lighting, then the system is energy efficient and simple to control, but it causes passenger eye strain when ambient light conditions change
Solution Approach 1:
The system uses ambient light sensors to continuously monitor cabin lighting conditions and automatically adjusts IFE display lighting brightness in response. When ambient light levels change, the controller receives sensor feedback and dynamically modifies display brightness to maintain comfortable viewing conditions, preventing eye strain without requiring manual passenger intervention.
Solution Approach 2:
The IFE display lighting system self-adjusts its brightness based on ambient light sensor data processed by the controller. The system automatically adapts to changing cabin conditions, maintaining optimal brightness levels to prevent passenger eye strain without requiring manual control, thereby improving comfort while maintaining operational simplicity.

AI summary
Methods and systems are provided for a transportation vehicle. One method includes computing an average of light sensor data of a first group of seat devices; comparing the computed average with a previous average of the first group and at least a second group; determining that the computed average of the light sensor data of the first group is different from the previous average by a threshold value; identifying a change in an ambient light condition based on a difference between the computed average and the previous average of the light sensor data of the first group and comparison of the computed average with the average of the light sensor data of the second group; and automatically adjusting a brightness level of the seat devices of the first group, in response to the change in the ambient light condition.
