Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional vehicle lighting devices use multiple components (reflectors, cut-off devices), then lighting function is achieved, but device complexity increases and adaptability to vehicle styling decreases
Solution Approach 1:
The fiber optic panel serves multiple lighting functions simultaneously - it can provide tail lamp illumination, stop light function, and aesthetic lighting effects all through a single integrated panel structure, eliminating the need for separate reflectors and cut-off devices for each function
Solution Approach 2:
The patent combines multiple lighting components into a single fiber optic panel assembly, merging the functions of reflectors, light sources, and styling elements into one integrated structure that adapts to vehicle contours
2Adaptability or versatility
If fiber optic panels are used for vehicle lighting, then aesthetic appeal and adaptability improve, but meeting regulatory lighting standards becomes more difficult
Solution Approach 1:
The fiber optic panel incorporates different optical properties in different regions - some areas have abraded fibers for diffuse scattering to meet illumination requirements, while other areas maintain smooth fibers for aesthetic appearance, allowing simultaneous compliance with lighting standards and aesthetic goals
Solution Approach 2:
The patent modifies fiber optical parameters by abrasing selected fibers to change light scattering characteristics, enabling the panel to meet minimum photometric intensity requirements while maintaining aesthetic appeal through controlled light distribution patterns
3Ease of operation
If abraded fiber arrays are used for light scattering, then light distribution improves, but manufacturing precision requirements increase
Solution Approach 1:
The patent applies abrasing treatment to only specific portions of the fiber panel rather than the entire surface, allowing controlled light scattering in specific regions while maintaining manufacturing feasibility through selective rather than universal treatment

AI summary
A lighting device for a vehicle includes a lighting module for a vehicle having a light source (20, 20a) and a panel (330) optically coupled to the light source. The panel (330) includes a plurality of fibers (44, 44a), and a first illumination region (A) of first light output for a first vehicle lighting function and a second illumination region (A') of second light output for a second vehicle lighting function.
