Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed illumination range is used in existing indicator lamps, then the structure is simple and reliable, but the adaptability to different driving states and information display requirements is poor
Solution Approach 1:
The patent applies the dynamics principle by making the shielding assembly movable rather than fixed. The driving assembly drives the shielding assembly to move to different positions, dynamically adjusting the illumination range and light pattern according to different driving states and information display requirements, thereby resolving the contradiction between adaptability and structural complexity
Solution Approach 2:
The patent implements multi-functionality by enabling the same light module to perform multiple functions: indication, illumination, navigation information display, and driving assistance information display. The movable shielding assembly allows a single device to adapt to various driving states and display different types of information, achieving universality without requiring separate fixed devices for each function
2Adaptability or versatility
If multiple movable members are added to adjust illumination patterns, then the adaptability to different driving states is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the shielding assembly into multiple independent movable members (first movable member, second movable member, third movable member). Each movable member can be independently positioned to adjust different parameters of the illumination pattern such as length, width, and shape, enabling fine-grained control over the light display while maintaining modular structure
Solution Approach 2:
The patent uses the driving assembly as an intermediary mechanism that coordinates the movement of multiple movable members. The driving assembly receives driving instructions and translates them into coordinated movements of the shielding assembly components, simplifying the control architecture and reducing the overall system complexity despite having multiple movable parts
3Loss of information
If the shielding assembly moves to change relative position with the first beam, then the target light pattern is adjusted for better information conveyance, but the device complexity increases
Solution Approach 1:
The patent implements feedback by having the driving assembly receive driving instructions (which may include navigation information, driving assistance information, or head unit data) and automatically adjust the shielding assembly position accordingly. This closed-loop control ensures that the illumination pattern accurately reflects the intended information to be conveyed, improving information conveyance effectiveness while automating the adjustment process
Solution Approach 2:
The system applies self-service by enabling the light module to automatically adjust its own illumination pattern based on received driving instructions without requiring manual intervention. The driving assembly and movable shielding members work together to autonomously configure the light display according to the current driving state and information requirements, reducing operational complexity

AI summary
A vehicle light module includes a light source assembly, a driving assembly, and a shielding assembly. The driving assembly is connected to the shielding assembly. The light source assembly is configured to send a first beam to the shielding assembly, where the shielding assembly is located on a transmission optical path of the first beam. The driving assembly is configured to drive, according to a driving instruction, the shielding assembly to move, to change a relative position between the shielding assembly and the first beam. A second beam emitted from the shielding assembly is displayed on a path around the vehicle in a target light pattern. The shielding assembly includes at least one movable member, at least a part of the first beam is illuminated on the at least one movable member, and a shape of a cross section of the second beam corresponds to the target light pattern.
