Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lamps require complex configurations and increased costs to form light distribution patterns with multiple regions, as each pattern region necessitates a separate optical system.
Innovation Solution
A vehicle lamp design incorporating a light source unit with multiple light sources, an optical unit featuring incidence and emission lenses, and shields, along with a light transmission unit that divides light into distinct transmission regions to form multiple pattern regions without separate optical systems for each, allowing for simplified configuration and common component usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If separate optical systems are provided for each pattern region, then each pattern region can be formed with precise control, but the configuration becomes complicated and cost increases
Solution Approach 1:
A single optical system is designed to perform multiple functions by forming multiple different pattern regions (first pattern region and second pattern region) using the same light source and optical components. The optical system achieves versatility by controlling light transmission through different transmission regions to create various patterns, eliminating the need for separate optical systems for each pattern region.
Solution Approach 2:
The optical system is divided into multiple transmission regions (first transmission region and second transmission region) that can independently control light transmission to form different pattern regions. Each transmission region acts as a segmented functional unit within the unified optical system, allowing precise control over different pattern areas while maintaining system integration.
2Adaptability or versatility
If separate optical systems are provided for each pattern region, then each pattern region can be independently controlled, but the cost increases
Solution Approach 1:
The optical system is designed as a universal platform that can generate multiple different light distribution patterns through a single configuration. By using the same light source and optical components to create both the first and second pattern regions, the system reduces manufacturing costs while maintaining the flexibility to control different pattern regions independently through the segmented transmission regions.
3Adaptability or versatility
If multiple light sources are used to form multiple pattern regions, then pattern regions can be formed at different distances, but the configuration becomes more complex
Solution Approach 1:
The optical system is segmented into multiple transmission regions that correspond to different light sources and different pattern regions. Each transmission region can be independently configured to control light transmission at specific distances, allowing the system to achieve versatile distance coverage while maintaining a unified and relatively simple overall configuration.
