Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automotive headlamp systems are limited by the independent structure of daytime running lights (DRL), front position lamps (PL), and turning lights (TL), which occupy significant space and restrict design diversity, making it difficult to miniaturize and diversify the lamp's shape.
Innovation Solution
An automotive headlamp system that integrates a rotating shaft with multiple light-transmitting plates of varying materials and shapes, allowing selective light transmission to achieve different signaling functions, reducing the overall volume and enabling more design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DRL, front PL, and TL are independent modules, then each signal lamp function can be achieved, but the headlamp volume increases and design diversity is limited
Solution Approach 1:
The patent merges multiple independent signal lamp modules (DRL, front PL, TL) into a single integrated headlamp structure. The light-transmitting plate is positioned to simultaneously serve multiple signaling functions, eliminating the need for separate modules and reducing overall headlamp volume while maintaining all required signal lamp capabilities.
Solution Approach 2:
The light-transmitting plate is designed as a multi-functional component that can perform multiple signaling functions (DRL, position lamp, turning light) through a single structure. This universal component replaces multiple dedicated modules, achieving space reduction while preserving functional versatility.
2Reliability
If traditional signal lamp structure is used, then signaling function is achieved, but the headlamp volume increases and miniaturization is limited
Solution Approach 1:
The patent extracts the essential signaling function from traditional bulky signal lamp modules and implements it through a simplified light-transmitting plate structure. By taking out only the necessary light transmission capability and eliminating redundant module components, the solution achieves miniaturization while preserving reliable signaling functionality.
3Device complexity
If direct combination of LED light source and light guide is used, then structure is simple, but the lamp shape is limited and cannot be diversified
Solution Approach 1:
The patent introduces a rotatable light-transmitting plate that can dynamically change its rotational position to achieve different signaling functions. This dynamic component allows the headlamp to adapt to various functional requirements and design shapes without increasing structural complexity, as the rotation mechanism provides versatility through motion rather than multiple static components.

Implementation Method 1
The light-transmitting portion includes a plurality of light-transmitting plates, and the plurality of light-transmitting plates (32) are different in material and/or shape, each light-transmitting plate corresponds to a different signaling function

AI summary
An automotive headlamp system and an automotive lamp. The automotive headlamp system comprises a light source, a primary optical element (1), an automotive signal lamp structure, and a secondary optical element (2), which are arranged in sequence along the light emitting direction. The automotive signal lamp structure comprises a light-transmitting portion and a rotating shaft (31). The light-transmitting portion comprises at least one light-transmitting plate (32). The light-transmitting plate (32) is mounted on the rotating shaft (31) and can be driven to rotate by the rotating shaft (31) such that, by means of rotation, light from the light source exits by means of the primary optical element (1), then selectively passes through one of the light-transmitting plates (32) or does not pass through any one of the light-transmitting plates (32), and then is projected by means of the secondary optical element (2) to achieve a corresponding signal lamp function or lighting function. The light-transmitting plate (32) mounted on the rotating shaft is used to replace a signal lamp in the existing technology, thereby reducing the space occupied by the original signal lamp, decreasing the volume of a headlamp, and satisfying requirements for the miniaturization of an automobile lamp.
