Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple light sources are used to create different illumination patterns, then the adaptability and versatility of the lighting system is improved, but the device complexity increases
Solution Approach 1:
The lighting system is divided into multiple independent light sources (first light source, second light source, third light source) that can be individually controlled to create different illumination patterns. Each light source corresponds to a specific door opening event, allowing the system to provide targeted illumination where needed while maintaining overall system simplicity through modular design.
Solution Approach 2:
The lighting system dynamically adjusts which light sources are activated based on real-time vehicle conditions (door opening events). The controller selectively activates specific light sources corresponding to opened doors, transforming a static lighting system into a dynamic one that adapts to changing conditions without requiring all light sources to be permanently active.
2Measurement precision
If a light sensor is added to detect contaminants on the lens, then the measurement precision and reliability are improved, but the device complexity increases
Solution Approach 1:
The lighting system performs self-diagnosis by using a light sensor to detect contaminants on its own lens. The system monitors the clarity of light passing through the lens and automatically identifies when cleaning is needed, eliminating the need for separate manual inspection systems and enabling the lighting system to maintain its own performance.
Solution Approach 2:
The light sensor provides feedback about the lens condition (presence of contaminants) back to the control system. This feedback mechanism allows the system to monitor its own performance and trigger appropriate responses (such as cleaning alerts or adjustments) based on the detected contaminant levels, creating a closed-loop control system.

Function Achieved in This Case
The system provides adaptive and efficient illumination patterns that enhance safety and visibility around the vehicle, while also maintaining cleanliness and functionality by detecting and addressing contaminants on the lighting surfaces.
Implementation Method 1
A light sensor is configured to detect a presence of a compound on an outer surface of said light system by detecting an amount of incident light reflected by an inner surface of the lens

AI summary
A light system for a vehicle is provided herein. The light system includes first and second light sources. A lens is configured to create a first illumination pattern when the first light source is activated and a second illumination pattern when the second light source is activated. A third light source is configured to create a third illumination pattern that extends vehicle outward of the first and second illumination patterns. A controller is configured to activate the first light source when a front door of the vehicle is opened and activate the second light source when a rear door of the vehicle is opened.
