Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interior decorative and panel parts lack the ability to dynamically change optical light effects on the visible side, limiting their aesthetic and functional versatility.
Innovation Solution
A shaped part with a decorative layer that features light-transmissive recesses filled with different colors or covered with color layers, combined with a dual- or multispectral light element that emits adjustable light colors, allowing for dynamic illumination and visibility of symbols or decorations based on the light color emitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a decorative layer with light-transmissive recesses is used, then optical light effects are enhanced, but the ability to dynamically change designs is limited
Solution Approach 1:
The patent applies color filters in the light-transmissive recesses that selectively transmit different wavelengths of light. By using a dual- or multispectral light element that can emit different light colors, the visible design changes dynamically based on which color filter transmits the emitted light. For example, when the light element emits blue light, blue color filters transmit it while red and green filters block it, making blue-patterned regions visible and others invisible.
Solution Approach 2:
The patent implements dynamic design changes by making the light element capable of emitting different light colors (dual- or multispectral). This allows the decorative layer to display different visible patterns depending on the emitted light color, enabling the same physical structure to dynamically change its visual appearance without physical reconfiguration.
2Adaptability or versatility
If multiple color filters are used in light-transmissive recesses, then multiple optical effects can be realized, but manufacturing complexity increases
Solution Approach 1:
The patent uses a single dual- or multispectral light element that serves multiple functions by emitting different light colors. This one component enables multiple optical effects and design variations, replacing what would otherwise require multiple separate light sources or complex mechanical systems for changing designs.
Solution Approach 2:
The patent incorporates multiple color filters (red, green, blue) in different light-transmissive recesses. These color filters are applied during manufacturing using standard techniques such as printing or coating, allowing multiple optical effects to be achieved through material selection and arrangement rather than complex assembly processes.
3Illumination intensity
If the decorative layer is made opaque except for recesses, then light effects are enhanced, but visibility without backlighting is lost
Solution Approach 1:
The patent uses color filters in the light-transmissive recesses that selectively transmit light based on wavelength. When the light element emits a specific color, the corresponding color filter transmits it while blocking other colors, enabling visibility control without changing the opaque nature of the decorative layer. This maintains strong light effects while providing selective visibility through color matching.
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
Enables the creation of changing designs and the selective visibility of symbols or decorations on the visible side by adjusting the light color, enhancing aesthetic appeal and functional versatility, while maintaining a no-show-effect when the light element is switched off.
Implementation Method 1
The first color filter transmits the first light color more than the second light color, and the second color filter transmits the second light color more than the first light color, based on wavelength spectrum differences

AI summary
A shaped part can include a decorative layer having a front side and a rear side, which is opaque except for light-transmissive recesses, and at least one light element which emits light onto the rear side of the decorative layer. The recesses comprise a first and second recess, where the first recess is filled with a first color and/or covered on the rear side of the decorative layer with a first color layer formed by the first color, and the second recess is filled with a second color and/or covered on the rear side of the decorative layer with a second color layer formed by the second color, The light element (24) can emit at least one first and one second light color, wherein the wavelength spectrum of the first light color differs from the wavelength spectrum of the second light color.
