Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Passenger seat back environments in aircraft or vehicles lack integrated mood lighting solutions that can enhance passenger experience through adjustable lighting levels and colors, especially in areas used for entertainment devices and storage.
Innovation Solution
A display assembly integrated with a passenger seat back, featuring a video shroud and a light apparatus with adjustable lighting elements, including LEDs, that can emit light through a gap between the display and the shroud, with a controller to adjust color, intensity, or pattern based on detected conditions or passenger input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mood lighting is incorporated into passenger seat backs with entertainment devices and storage areas, then passenger experience and aesthetic appeal are enhanced, but device complexity and structural integration become more challenging
Solution Approach 1:
The lighting apparatus is merged with the seat back structure, integrating the light sources, diffusers, and control systems into the existing seat framework. This combining approach allows mood lighting to be incorporated without adding separate, complex structures, as the lighting elements are embedded within the seat back's existing compartments and surfaces.
Solution Approach 2:
The seat back structure is designed to serve multiple functions: it provides structural support, houses entertainment devices, contains storage compartments, and integrates mood lighting systems. This multi-functionality approach allows a single structural element to fulfill several purposes, reducing overall system complexity while enhancing passenger experience.
2Illumination intensity
If lighting elements are positioned to emit light through gaps between display and shroud, then aesthetic lighting effects are achieved, but manufacturing precision requirements increase
Solution Approach 1:
The lighting system employs local quality by positioning light sources at specific locations within the seat back structure and using diffusers at particular gaps between the display and shroud. This targeted approach allows lighting effects to be achieved at specific zones without requiring uniform precision across the entire structure, as each lighting element is strategically placed to illuminate particular areas.
Solution Approach 2:
Diffusers are introduced as intermediary elements between the light sources and the visible gaps. These diffusers mediate the light transmission, allowing lighting effects to be achieved even when precise gap positioning is difficult to maintain. The diffusers compensate for variations in gap dimensions while still producing the desired aesthetic lighting effects.
3Ease of operation
If adjustable lighting controls are added to modify color, intensity, or pattern, then passenger comfort and safety awareness are improved, but device complexity and control system requirements increase
Solution Approach 1:
The lighting system incorporates dynamic controls that allow adjustment of color, intensity, and pattern based on different operational conditions. The system can dynamically adapt lighting parameters in response to detected conditions such as unsafe events, providing enhanced passenger comfort and safety awareness while maintaining manageable complexity through condition-based automation.
Solution Approach 2:
The control system incorporates feedback mechanisms that detect unsafe conditions and automatically adjust lighting parameters in response. This feedback approach allows the lighting system to enhance passenger safety and comfort automatically based on detected conditions, reducing the need for complex manual controls while still providing adjustable lighting functions.
