Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display elements in the automotive sector face challenges in providing a visually uniform and appealing information display across different lighting conditions while being cost-effective and simple to produce, often resulting in noticeable transitions between layers and increased manufacturing effort.
Innovation Solution
A display element comprising a carrier layer, a display layer, and a cover layer with a transition region where the display layer's color density decreases from the inner edge to the outer edge, creating a smooth transition and blending the layers' appearances, with optional illumination for improved readability in poor lighting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple layers of paint or film with different properties are applied to a carrier layer, then the display element can provide information in different lighting conditions, but harsh transitions between different layers or appearances become visible
Solution Approach 1:
The display layer is designed with spatially varying color density: higher color density in the central display area for information visibility, and progressively lower color density toward the edges for smooth visual blending with the cover layer. This local variation in optical properties eliminates harsh transitions while maintaining adaptability across lighting conditions.
Solution Approach 2:
The color density parameter of the display layer is continuously varied from the inner edge to the outer edge, creating a gradient transition zone. This parameter change enables the display layer to optically merge with the cover layer, achieving visual uniformity while preserving the functionality of multiple layers for different lighting conditions.
2Shape
If the color density of the display layer is reduced in the edge region, then the transition between layers becomes smoother, but the visibility of display symbols may be compromised
Solution Approach 1:
Different regions of the display layer are assigned different color density values: the central region maintains high color density for clear symbol visibility, while the peripheral edge regions use reduced color density for smooth transitions. This localized optimization ensures that information visibility is preserved where needed while achieving aesthetic smoothness where symbols are not displayed.
3Shape
If a single film is used for the entire surface to avoid transitions, then visual consistency is achieved, but the ability to display information in different lighting conditions is limited
Solution Approach 1:
The surface is segmented into multiple functional layers: a carrier layer, a display layer with spatially varying color density, and a cover layer. This segmentation allows each layer to serve its specific function while the gradient transition zone ensures visual consistency across the entire surface, reconciling both requirements.
4Adaptability or versatility
If multiple layers with different properties are used, then information can be displayed in different lighting conditions, but the manufacturing effort and cost increase
Solution Approach 1:
Instead of requiring multiple precisely matched layers with identical optical properties, the invention achieves the desired effect by varying the color density parameter within a single display layer. This approach maintains the adaptability for different lighting conditions while significantly simplifying the manufacturing process and reducing costs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves a uniform and visually cohesive surface appearance, making the display element appear as a single material, enhancing readability and design integration without increasing production complexity or costs.
Implementation Method 1
The color density of the display layer decreases in the edge region from the inner edge to the outer edge, so that the visual appearance of the display layer merges smoothly into the visual appearance of the cover layer. The color density is the number of pigments in an edge region section and/or the opacity of the pigments in an edge region section. The color density therefore determines the transparency in an edge region section.
