Solution Overview

Problem

Existing vehicle interior lighting systems, such as those in aircraft, cannot independently adjust the illumination intensity of individual lighting elements, resulting in aesthetically unimpressive uniform illumination throughout the seating area.

Innovation Solution

An interior panel with a lighting system featuring a controller that directs each light source independently to generate varying illumination patterns, allowing for customizable and dynamic lighting by placing light sources in hidden channels within the trim sections and using a user interface to adjust illumination intensity and shape.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If lighting elements operate collectively with uniform illumination intensity, then the lighting system is simple to control, but the aesthetic appeal and visual interest are reduced

Engineering Contradiction:
Improveuniform illumination intensityVSAvoidlighting control complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The lighting system divides the interior panel into multiple independently controllable lighting elements (first lighting element, second lighting element, etc.), each capable of operating at different illumination intensities. This segmentation allows the controller to create varied illumination patterns across different zones of the vehicle interior, transforming uniform lighting into dynamic, aesthetically appealing patterns while maintaining manageable control complexity through a centralized controller.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system applies different illumination intensities to different local zones of the vehicle interior. The controller can independently adjust the brightness of each lighting element to create specific illumination patterns (e.g., brighter areas near exits, softer lighting in seating areas), allowing local customization of lighting quality to enhance aesthetic appeal and functionality without requiring complete system redesign.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If lighting elements are independently adjustable, then aesthetic appeal and customization are improved, but control complexity increases

Engineering Contradiction:
Improvelighting customization capabilityVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The controller serves multiple functions: it independently manages each lighting element's intensity, creates various illumination patterns, responds to different operational modes (cruising, landing, emergency), and interfaces with the vehicle's existing management systems. This multi-functionality consolidates what would otherwise require multiple separate control systems into a single versatile unit, enhancing adaptability while preventing control complexity from escalating.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines multiple lighting elements and their control functions into a single integrated lighting system managed by one controller. Rather than having separate control mechanisms for each lighting element, the system merges all control functions into a unified architecture that can simultaneously manage multiple zones with different illumination requirements, thereby achieving high versatility without proportional increases in control complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Shape

If lighting array is hidden from interior, then aesthetic appearance is improved, but light distribution control becomes more difficult

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidlight distribution control
Core Design Contradiction:
ShapeVSDevice complexity

Solution Approach 1:

The system introduces an intermediary medium (the interior panel material itself) through which light from the hidden lighting array is transmitted and diffused. The lighting elements are positioned behind or within the panel structure, and the panel material acts as a diffuser that evenly distributes light across the visible surface. This intermediary approach allows the lighting array to remain hidden for aesthetic purposes while still achieving effective and controllable light distribution through the panel.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Interior panels for an interior of a vehicle, vehicles, and methods for making interior panels for an interior of a vehicle are provided. In one example, the interior panel includes a first trim section having a first exposed surface configured to face towards the interior. A second trim section that has a second exposed surface configured to face towards the interior is disposed adjacent to and spaced apart from the first trim section to define a gap. A first lighting array that includes light sources is configured to be disposed proximate the gap hidden from the interior by the second trim section. A controller is configured to be in communication with the first lighting array to independently direct each of the light sources to generate light that passes through the gap into the interior and illuminates the first exposed surface to define an illumination pattern.
