Modular Backlit Trim Element With Multi-Layer Optical Shuttering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle trim elements with backlit areas have limited modularity, allowing only two distinct appearances based on the configuration of optical obturation areas, which restricts the ability to display information and enhance aesthetics.
Innovation Solution
Incorporating a second translucent aspect layer and obturation layer with configurable optical obturation areas, allowing for multiple configurations and appearances by controlling the passage of light through different combinations of open and closed positions, shapes, and sizes of optical obturation areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single obturation layer with optical obturation areas is used to control light passage, then the structure remains simple, but the appearance modularity is limited to only two distinct states
Solution Approach 1:
The obturation function is segmented into multiple independent layers (first obturation layer and second obturation layer), each capable of independent optical control. This segmentation allows each layer to contribute separately to the overall appearance, enabling combinations that produce more than two distinct visual states while maintaining manageable complexity through modular design
Solution Approach 2:
The solution adds a dimensional aspect by introducing multiple stacked layers instead of relying on a single layer's binary state. This vertical stacking creates additional degrees of freedom in light modulation, transforming a one-state system into a multi-state system through the superposition of multiple optical layers
2Adaptability or versatility
If multiple aspect layers and obturation layers are added to increase appearance modularity, then the number of distinct appearances increases to at least three, but the device complexity increases
Solution Approach 1:
The system is divided into discrete, independently controllable segments (first aspect layer, second aspect layer, first obturation layer, second obturation layer), where each segment can be independently configured. This segmentation allows for combinatorial appearance states without requiring complex interdependencies between components
Solution Approach 2:
The obturation layers incorporate dynamically controllable optical obturation areas that can switch between translucent and opaque states. This dynamic control enables the system to transition between multiple appearance states on demand, achieving high adaptability through active control rather than fixed structural complexity

Function Achieved in This Case
This approach significantly increases the modularity of the outer surface appearance, enabling at least three distinct appearances and enhancing the display of information and aesthetics by allowing for various configurations and patterns.
Implementation Method 1
at least one lighting device opposite the outer surface, extending on the inner surface side of the first aspect layer and emitting light toward said first aspect layer
Implementation Method 2
each first optical obturation area being configurable between an open position, in which said first optical obturation area allows light to pass from the lighting device to the first aspect layer, and a closed position, in which said first optical obturation area prevents the passage of light

AI summary
A trim element having a first aspect layer, a lighting device emitting light to the first aspect layer, and a first obturation layer extending between the lighting device and the first aspect layer. The first obturation layer includes at least two first optical obturation areas, configurable between an open position, in which a first optical obturation area lets light pass through, and a closed position, in which a first optical obturation area prevents the passage of light. The trim element includes a second aspect layer and a second obturation layer having at least two second optical obturation areas that are configurable between an open position and a closed position.
