Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional turning light lamp with a curved reflector and halogen bulb is used, then single-segment lighting is provided, but the lamp becomes bulky and lacks flexibility in illumination patterns
Solution Approach 1:
The lamp is divided into multiple light-emitting segments, each corresponding to a specific steering angle range. The light divider arrangement partitions the illumination area into multiple channels, allowing selective activation of different segments based on actual steering conditions. This segmentation enables flexible illumination patterns while maintaining a compact overall structure.
Solution Approach 2:
The turning light lamp dynamically adjusts which light-emitting elements are activated based on the detected steering angle. The control unit selectively turns on or off specific light-emitting elements according to the steering angle, enabling adaptive illumination that matches actual turning conditions while reducing energy consumption and maintaining compact design.
2Reliability
If a conventional turning light lamp with a curved reflector is used, then illumination is provided during vehicle turns, but the structure is bulky and complex
Solution Approach 1:
The patent combines multiple light-emitting elements (LEDs) with a light divider arrangement and control unit into an integrated compact structure. The lamp housing assembly integrates the substrate, light divider, and lens into a unified design, reducing overall structural complexity while maintaining reliable illumination functionality for vehicle turning safety.
Solution Approach 2:
The patent replaces the conventional halogen bulb and curved reflector mechanical system with an LED-based lighting assembly and optical control system. This substitution reduces structural complexity, improves energy efficiency, and enhances reliability while maintaining the essential function of providing illumination during vehicle turns.
3Adaptability or versatility
If multiple light-emitting elements are used for multi-segmented illumination, then adaptability to different steering angles is improved, but device complexity increases
Solution Approach 1:
The control unit receives feedback regarding the steering angle and automatically selects which light-emitting elements to activate. This feedback mechanism enables the system to adapt to different steering angles without requiring complex manual control, as the system autonomously adjusts the illumination pattern based on actual steering conditions.
Solution Approach 2:
The control unit serves multiple functions: it detects steering angle, determines the appropriate illumination segment, and controls the activation of corresponding light-emitting elements. This multi-functionality reduces the need for separate control mechanisms for each light-emitting element, thereby managing device complexity while maintaining high adaptability to various steering angles.
