Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ambient lighting is used only for decoration, then the aesthetic appeal is enhanced, but the functionality remains limited
Solution Approach 1:
The lighting system is designed to perform multiple functions: decoration, object detection, positioning, and identification. The same lighting devices that provide aesthetic appeal are also used as active sensors to detect objects, determine their positions, and identify them through image capture, eliminating the need for separate dedicated detection hardware
Solution Approach 2:
The lighting devices are divided into multiple groups, with each group responsible for specific functional tasks. This segmentation allows the system to independently control different lighting groups for different purposes (e.g., one group for detection, another for illumination), thereby enhancing versatility while maintaining manageable system complexity
2Measurement precision
If traditional positioning methods are used, then positioning accuracy is achieved, but positioning costs increase
Solution Approach 1:
The lighting devices serve dual purposes: they provide illumination for aesthetics and simultaneously function as positioning sensors. By capturing images when illuminated and using the lighting group identification information, the system determines object positions without requiring separate positioning hardware, thereby achieving accurate positioning while reducing costs
3Measurement precision
If lighting devices are grouped with position offsets, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
Lighting devices are segmented into distinct groups with defined position offsets relative to each other. Each group's spatial relationship is predetermined and stored, allowing the system to calculate object positions by identifying which group illuminated the object. This segmentation structure simplifies the complexity by providing clear spatial relationships rather than requiring complex continuous control
Solution Approach 2:
The system uses the known spatial configuration (copy) of lighting device groups to determine object positions. By capturing an image and identifying which lighting group illuminated the object, the system maps the object's position based on the pre-known positions of the lighting groups, achieving accurate positioning through this simplified copying approach

AI summary
This application relates to a control method and apparatus. The method is applied to a vehicle including a plurality of lighting devices, and the plurality of lighting devices are disposed at different positions of the vehicle. In the method, a plurality of lighting device groups may be determined. Each of the plurality of lighting device groups includes one or more of the plurality of lighting devices, and different lighting device groups in the plurality of lighting device groups include different lighting devices. Therefore, the plurality of lighting device groups may be controlled, based on light turn-on strategy information of the plurality of lighting device groups, to emit light. In this way, intelligence of a lighting system in the vehicle can be improved, enhancing user experience. In addition, the light turn-on strategy information of the plurality of lighting device groups may be used to determine a first position of a to-be-detected object. This can implement positioning through a lighting device group that emits light, thereby reducing positioning costs, protecting user privacy, and enhancing a user's sense of security.
