Solution Overview
Problem
Current vehicular rear lighting systems lack the ability to dynamically adjust illumination patterns based on various vehicle actions and conditions, such as reversing, braking, or turning, which can lead to inadequate visibility and safety concerns.
Innovation Solution
A vehicle lamp system with a housing containing angularly offset light sources and reflectors, coupled with a controller that selectively illuminates in multiple patterns, utilizing luminescent structures to alter illumination based on vehicle actions and conditions, such as reversing, braking, or turning, to provide enhanced visibility and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple light sources with angularly offset reflectors are used to provide dynamic illumination patterns, then visibility and safety are improved, but device complexity increases
Solution Approach 1:
The lighting system is divided into multiple independent light sources (first plurality and second plurality), each with its own angularly offset reflector. This segmentation allows each component to be controlled independently to create different illumination patterns, improving visibility and safety while maintaining manageable complexity through modular design
Solution Approach 2:
The same physical components (light sources and reflectors) serve multiple functions by being selectively activated in different combinations. The controller enables these components to produce various illumination patterns for different vehicle conditions (reversing, braking, turning), achieving multi-functionality without adding separate dedicated components for each function
2Adaptability or versatility
If angularly offset light sources and reflectors are arranged to provide multiple illumination patterns, then adaptability to various vehicle actions is improved, but manufacturing precision requirements increase
Solution Approach 1:
The reflectors are deliberately designed with asymmetric angular offsets relative to their associated light sources. This asymmetric configuration is optimized to direct light in specific patterns for different vehicle actions. The angular offsets are fixed during manufacturing to provide reliable adaptability while reducing the need for complex adjustable mechanisms
Solution Approach 2:
Different regions of the lighting assembly have different reflector angles and light source positions optimized for specific functions. For example, certain reflectors are angled to illuminate for reversing conditions while others are positioned for braking visibility. This local optimization allows the system to adapt to various vehicle actions through selective activation rather than requiring uniform high-precision adjustment across all components
