Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lamp systems are used for basic illumination, then the lighting function is simple and reliable, but the system lacks interactive functionality and cannot provide a luxurious and intelligent user interface
Solution Approach 1:
The surrounding lamp system is designed to perform multiple functions: basic illumination, welcome function when user approaches, and interactive motion-tracking illumination. The same lamp structure and control system handle all these functions, making the system multi-functional without requiring separate dedicated systems for each function.
Solution Approach 2:
A camera and controller are introduced as intermediary components between the user and the lamp system. The camera captures user motion, the controller processes this information to determine motion directionality, and then controls the lamp sectors accordingly. This intermediary system enables interactive functionality while keeping the lamp structure itself relatively simple.
2Illumination intensity
If the surrounding lamp system activates all sectors continuously to provide comprehensive illumination, then the illumination coverage is complete, but the energy consumption increases and the interactive effect is reduced
Solution Approach 1:
Instead of uniformly illuminating all sectors, the system activates only the specific lamp sectors corresponding to the user's motion direction. For example, when the user moves toward the front left, only the front left sector is activated. This localized illumination approach provides adequate lighting coverage while significantly reducing energy consumption compared to continuous full-system activation.
Solution Approach 2:
The lamp system dynamically adjusts which sectors are activated based on real-time user motion detection. The controller continuously monitors camera input and updates the active sectors accordingly, allowing the illumination pattern to adapt dynamically to user behavior rather than maintaining a static illumination state.
3Speed
If the lamp system responds immediately to user motion for highly interactive behavior, then the responsiveness is high, but the system may trigger falsely due to environmental factors
Solution Approach 1:
The system uses feedback from the camera to continuously monitor user motion and adjust lamp activation accordingly. By processing camera images to determine actual user motion directionality, the system can distinguish between genuine user movement and environmental disturbances, reducing false triggering while maintaining responsive interaction.
Solution Approach 2:
The controller is configured to activate lamp sectors in advance based on predicted user motion trajectories. By analyzing the directionality of user motion, the system can pre-activate relevant sectors before the user actually reaches them, improving perceived responsiveness while the predictive nature of the activation helps filter out spurious motion signals.
Data Source
AI summary
A system and method of controlling a surrounding lamp system of a vehicle are provided. The method includes sensing an approach of the user to the vehicle acquiring an image of the user with respect to a vehicle body, when the user approaches the vehicle body. A motion of the user, the motion having directionality with respect to the vehicle body is determined from the image and a surrounding lamp is then operated based on the motion having directionality with respect to the vehicle body.
