Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mechanical parts are used to adjust light patterns for Dynamic Bending Light functionality, then the light source can physically turn to illuminate the road during steering, but the device complexity increases and adaptability to varying driving conditions decreases
Solution Approach 1:
The patent replaces the mechanical angular movement converter system with an electronic control system that individually addresses solid-state light sources in a matrix arrangement. Instead of physically turning the entire light source assembly, the system electronically shifts which light sources are activated based on steering angle, thereby eliminating mechanical complexity while achieving the same Dynamic Bending Light effect
Solution Approach 2:
The lighting device is divided into a matrix arrangement of individually controllable solid-state light sources. This segmentation allows selective activation of specific light sources based on steering conditions, enabling adaptive lighting patterns without requiring mechanical movement of the entire assembly
2Device complexity
If solid-state light sources in a matrix arrangement are used to provide dynamic bending light, then device complexity is reduced and adaptability improves, but maintaining consistent luminous intensity across the light pattern becomes more challenging
Solution Approach 1:
The control system dynamically adjusts the luminous intensity parameter of individual solid-state light sources based on their position in the matrix and the detected steering angle. This allows compensation for the non-uniform light distribution that occurs when selectively activating light sources, ensuring that the overall light pattern maintains consistent intensity across the illuminated area
