Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple flat light conducting elements are arranged in a layered structure with spacing, then a three-dimensional visual effect is achieved, but the device complexity increases
Solution Approach 1:
The patent transitions from traditional two-dimensional lighting displays to a three-dimensional visual effect by arranging multiple flat light conducting elements in a layered structure with spacing. This dimensional expansion allows light to propagate through multiple layers and create depth perception, enabling meaningful 3D visual information transmission to vehicle occupants.
Solution Approach 2:
The lighting device is divided into multiple discrete light conducting elements arranged in separate layers. Each layer contains light conducting elements that are spatially separated and do not contact one another. This segmentation enables independent optical control of each layer while collectively producing the three-dimensional visual effect.
2Loss of information
If light scattering structural elements are added to light conducting elements, then visual information transmission is enhanced, but the manufacturing complexity increases
Solution Approach 1:
Light scattering structural elements are integrated into specific regions of the light conducting elements where needed to enhance visual information transmission. These structural elements are not uniformly distributed but are strategically placed to optimize light scattering effects and improve the clarity of transmitted visual signals to vehicle occupants.
3Loss of information
If sequential lighting effects are implemented across multiple layers, then visual signal clarity is improved, but the control system complexity increases
Solution Approach 1:
The patent implements sequential lighting effects where light conducting elements in different layers are illuminated in a time-dependent sequence. This periodic activation pattern creates dynamic visual effects that enhance signal clarity and convey information more effectively to vehicle occupants, with each layer being illuminated at different time intervals.

AI summary
A lighting device for a motor vehicle includes several flat light-conducting elements that are arranged in layers one behind the other in a layer arrangement. The individual light-conducting elements do not touch one another and are clearly spaced apart from one another. Each of the light-conducting elements includes a light-scattering structural element. An illuminating device is optically coupled to each of the light-conducting elements in order to couple light into the light-conducting elements. Light is coupled out of the light-conducting elements by means of the structural elements.
