Solution Overview
Problem
Existing vehicle lighting devices can only produce static light effects and require multiple light sources for dynamic lighting, which increases complexity and cost, making it difficult to achieve non-variant components for different lighting setups.
Innovation Solution
A lighting device with a line-shaped light source extending parallel to a line-shaped light emission element, where the light source is coupled into the light emission element via a longitudinal side, allowing for dynamic light effects and modular design with a releasable light emission element that can be easily exchanged, enabling both simple and high-quality light modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources are used to achieve dynamic light effects, then lighting versatility is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies dynamics by making the light emission element itself changeable rather than using multiple static light sources. The light emission element can be exchanged or reconfigured to produce different light effects, achieving lighting versatility through a single dynamic component rather than multiple static ones, thereby reducing device complexity.
Solution Approach 2:
The light emission element is designed to perform multiple functions - it can produce different light effects, patterns, and dynamics through a single element that can be exchanged or reconfigured. This universal component replaces the need for multiple specialized light sources, reducing both device complexity and manufacturing costs while maintaining lighting versatility.
2Adaptability or versatility
If multiple light sources are used for dynamic lighting, then lighting versatility is improved, but manufacturing cost increases
Solution Approach 1:
The patent employs a universal light emission element that can produce multiple light effects and patterns, replacing the need for multiple specialized light sources. This single multi-functional component simplifies manufacturing processes and reduces costs while maintaining the ability to achieve dynamic lighting effects through element exchange or reconfiguration.
Solution Approach 2:
Rather than manufacturing multiple static light sources for different effects, the patent uses a single dynamic light emission element that can be exchanged or reconfigured to produce different lighting effects. This dynamic approach reduces manufacturing complexity and cost while preserving lighting versatility.
3Adaptability or versatility
If different component variants are used for different lighting setups, then lighting versatility is improved, but device complexity and inventory requirements increase
Solution Approach 1:
The patent introduces a universal light emission element that can serve multiple lighting setup requirements through exchange or reconfiguration. Instead of maintaining inventory of different component variants for different lighting setups, a single universal element can be adapted to various configurations, reducing component complexity and inventory requirements while maintaining setup variety.
Solution Approach 2:
The patent segments the lighting system into a stable base structure and a replaceable light emission element. This segmentation allows the light emission element to be exchanged or reconfigured for different lighting setups without affecting the rest of the system, reducing the need for multiple complete component variants and simplifying inventory management.
4Ease of operation
If a releasable light emission element is used, then ease of exchange is improved, but connection reliability may worsen
Solution Approach 1:
The patent segments the lighting device into a stable housing and a releasable light emission element. The light emission element can be easily inserted and removed from the housing, providing ease of exchange for different lighting effects while maintaining a reliable connection during use through proper mechanical engagement features.

Data Source
AI summary
A lighting device for a vehicle includes a light source and a linear light emission element for emitting light, which is supplied by the light source via a coupling surface of the light emission element in the light emission element. A light conductor element is provided for distributing and/or directing light, which is supplied by the light emission element in the light conductor element. The light source is linear and is arranged so as to extend parallel to the light emission element so that light from the light source can be coupled to a longitudinal side of the light emission element in an in-coupling surface in the light emission element. The light emission element is arranged at least partially in one side of an open cavity of the light conductor element and force-fittingly and/or form-fittingly held and also can be detached from the light conductor element in a non-destructive manner.
