Solution Overview
Problem
Conventional car headlights lack the ability to dynamically adjust light distribution patterns according to varying road environments, leading to inadequate illumination and increased risk of accidents, particularly in changing conditions such as highways, town roads, and rainy or curved routes.
Innovation Solution
A smart headlight system comprising a main light source, auxiliary light sources, a lens, and a light shielding structure that allows for reciprocal movement of a light-shielding plate to produce different illumination modes, optimizing light distribution for various driving conditions by selectively shielding and refracting light to achieve desired illumination distances and angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adaptive front-lighting system (AFS) headlights are used to rotate light distribution patterns according to steering angle and driving conditions, then illumination adaptability to road environments is improved, but device complexity increases due to requiring multiple driving devices for left-right and up-down movement control
Solution Approach 1:
The headlight system is divided into multiple independent light-emitting modules (first light-emitting module, second light-emitting module, third light-emitting module) that can be independently controlled. Each module has its own light distribution pattern, allowing the system to achieve adaptive illumination by selectively activating different modules rather than mechanically rotating a single pattern, thus reducing mechanical complexity while maintaining adaptability.
Solution Approach 2:
The patent implements dynamic light distribution control by enabling independent on/off switching of multiple light-emitting modules based on detected driving conditions (steering angle, vehicle speed, acceleration). This dynamic electronic control replaces complex mechanical rotation mechanisms, achieving adaptability through software-controlled module activation rather than physical movement of light patterns.
2Adaptability or versatility
If multiple light-emitting modules with different light distribution patterns are used to convert light patterns, then illumination adaptability is improved, but the optical design becomes complicated and difficult for popularization
Solution Approach 1:
The optical system is segmented into multiple standardized light-emitting modules, each with a predetermined light distribution pattern (e.g., high beam, low beam, cornering light). By segmenting the system into modular units with standardized interfaces and mounting structures, the optical design becomes more manageable and easier to manufacture compared to a single complex rotating optical assembly.
Solution Approach 2:
The patent changes the control parameter from mechanical rotation angle to electronic module selection. Instead of continuously adjusting a single optical system's orientation, the system switches between discrete light-emitting modules with fixed but varied optical characteristics. This parameter change simplifies the optical design by using standardized, pre-engineered modules rather than requiring complex variable optical components.
3Device complexity
If conventional headlight modules are used with fixed light distribution patterns, then device structure is simple, but illumination cannot be adjusted according to driving conditions leading to safety issues
Solution Approach 1:
The headlight system achieves multi-functionality by integrating multiple light-emitting modules (high beam module, low beam module, cornering light module) into a single headlight assembly. This universal design allows the same physical structure to provide different illumination patterns suitable for various driving conditions (highway, town road, curve, rainy road), thereby maintaining structural simplicity while improving illumination adequacy and safety through functional versatility.

Implementation Method 1
the first light-reflecting cup has at least one first focal point located in an cover area of the first light-reflecting cup, and the first light-emitting unit corresponds in position to the at least one first focal point of the first light-reflecting cup
Implementation Method 2

AI summary
A smart headlight includes a headlight mount, a main light source, a lens and a light-shielding structure. The main light source is disposed on the headlight mount. The lens is connected to the headlight mount and corresponds in position to the main light source. The light shielding structure is disposed on the headlight mount and arranged between the main light source and the lens. The light shielding structure includes a first light-shielding plate and a second light-shielding plate. The first light-shielding plate is configured to reciprocally move between an upright position and a reclined position, such that a top portion of the second light-shielding plate can be covered by or exposed from the first light-shielding plate.
