Aircraft Lighting Control via Gesture Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for aircraft cabin lighting lack a comprehensive control solution that integrates overhead lighting, cabin lighting, window shade control, and air nozzle direction and flow rate, failing to provide a unified and passenger-centric comfort environment.
Innovation Solution
A lighting control system that uses sensors to detect passenger seat position, hand gestures, and presence, along with window shade and ambient light conditions, to generate control signals for adjustable light columns and patterns, integrating with air nozzle control for a cohesive comfort experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate control systems are used for overhead lighting, cabin lighting, window shades, and air nozzles, then each system can be controlled independently, but the overall system complexity increases and passenger comfort integration deteriorates
Solution Approach 1:
The patent combines multiple separate control systems (overhead lighting, cabin lighting, window shades, air nozzles) into a single integrated control system that responds to passenger hand gestures. This merging approach allows unified control of diverse comfort features through one interface, resolving the contradiction by prioritizing adaptability and passenger-centric control over system simplicity.
Solution Approach 2:
The control system is designed with multi-functionality to handle various comfort features (lighting, shading, air flow) through a single gesture recognition interface. This universal control mechanism enables one system to perform multiple functions, thereby integrating diverse subsystems without proportionally increasing overall system complexity.
2Ease of operation
If manual switches and bezels are used for overhead light control, then the control mechanism is simple, but passenger convenience and comfort are reduced
Solution Approach 1:
The patent replaces mechanical control mechanisms (manual switches, bezels) with a gesture recognition system that uses sensors to detect hand movements. This substitution eliminates the need for physical contact with control devices, significantly improving passenger convenience while the added electronic complexity is offset by the removal of mechanical components.
Solution Approach 2:
The system enables self-service control where passengers naturally gesture with their hands to adjust lighting and other comfort features without requiring learned operations or physical manipulation of controls. The gesture recognition system interprets intuitive hand movements, making the system easier to operate than traditional mechanical interfaces.
3Adaptability or versatility
If fixed lighting patterns are used, then the lighting system is simple, but adaptability to different passenger needs and environmental conditions is lost
Solution Approach 1:
The lighting system transitions from fixed patterns to dynamic control where lighting parameters (intensity, direction, color temperature) are continuously adjusted based on real-time detection of passenger hand gestures and environmental conditions. This dynamic behavior enables adaptability to different passenger needs while the control logic integrates seamlessly with the gesture recognition system.
Solution Approach 2:
The system incorporates feedback mechanisms where sensors detect passenger gestures and environmental conditions, and the control system adjusts lighting and other comfort features accordingly. This closed-loop control enables adaptive response to changing conditions while maintaining system coherence through centralized control logic.
Data Source
AI summary
A lighting control system includes a sensor to generate a signal representative of at least one of a position of a seat, a presence of passenger in the seat, the position of at least one hand of the passenger, a configuration of the at least one hand of the passenger, and a direction of movement of the at least one hand of the passenger. A first light source, which generates a first light column, is located forward of the seat. A second light source, which generates a second light column, is located rearward of the seat. A controller generates a control signal that controls at least one parameter associated with an intensity, a color, a projected pattern, projected pattern location, or a width formed by a combination of the first and second light columns.
