Segmented LCD Vehicle Lighting for Independent Light Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices for motor vehicles require a separate LCD for each light module, as is the case in the prior art, in which each LCD has different optical properties and pixel arrangements, leading to increased material usage and installation complexity.
Innovation Solution
A segmented LCD is placed in front of the light modules, with each segment having a dedicated light module or group, allowing for integrated light modules of varying sizes and shapes to modulate light without separate LCDs for each function, reducing material and installation difficulties, and providing a compact and aesthetically pleasing appearance, and incorporating a segmented LCD where the interior is concealed by a large LCD.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate LCD is used for each light module, then each lighting function can be independently controlled, but the amount of materials increases and installation becomes more complex
Solution Approach 1:
The patent combines multiple separate LCDs into a single integrated LCD that controls all light modules. The LCD is divided into multiple zones corresponding to different light modules (headlamp, high beam, daytime running light, turn signal), allowing independent control of each function while using only one LCD component, thereby reducing material quantity and simplifying installation.
2Adaptability or versatility
If a separate LCD is used for each light module, then each lighting function can be independently controlled, but material usage increases
Solution Approach 1:
The patent merges multiple separate LCD components into a single integrated LCD that serves all lighting functions. This single LCD is divided into multiple controllable zones, each corresponding to a specific light module, thereby reducing the total amount of LCD material needed while maintaining independent control capability for each lighting function.
3Reliability
If multiple separate LCDs are used, then each can have optimized optical properties, but the interior of the lighting device cannot be fully concealed
Solution Approach 1:
The patent uses a single large integrated LCD that covers the entire interior surface of the lighting device, creating a uniform and aesthetically pleasing appearance. The LCD is divided into multiple zones with different optical properties optimized for each lighting function, allowing full concealment of the interior while maintaining optimal optical performance for each segment.
4Device complexity
If a single integrated LCD is used, then material usage is reduced and installation is simplified, but different optical properties for different segments are required
Solution Approach 1:
The patent implements local quality by dividing the single integrated LCD into multiple zones, each with specifically optimized optical properties for its corresponding light module. For example, the headlamp zone has different transmission characteristics than the turn signal zone, allowing each segment to be optimized for its specific function while using a unified LCD structure.
