Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-structure headlight is used, then the structure is simple, but the functionality is limited and cannot automatically switch between illuminating and atmosphere lights
Solution Approach 1:
The headlight is divided into multiple independent light sources including main illuminating LED light sources and secondary atmosphere LED light sources, each with independent control. This segmentation allows the system to perform different functions by activating specific light sources, resolving the contradiction between functionality and structural complexity.
Solution Approach 2:
The headlight system is designed to perform multiple functions using a unified structure. The same physical housing and mounting structure support both main illuminating function and atmosphere lighting function, allowing one device to serve multiple purposes without proportionally increasing complexity.
2Reliability
If traditional headlights are used, then the structure is simple, but perception and identification between pedestrians and vehicles cannot be achieved
Solution Approach 1:
The headlight system uses different light colors to convey different information functions. Main illuminating light sources provide white light for visibility, while secondary atmosphere light sources emit colored light for identification and communication purposes. This color differentiation enables pedestrians and other drivers to distinguish between functional light modes, improving safety without requiring overly complex additional components.
3Illumination intensity
If single light source configuration is used, then the structure is simple, but illumination uniformity and distribution control cannot be achieved
Solution Approach 1:
Different regions of the headlight assembly are assigned different light sources with specific functions. The main illuminating LED light sources are positioned and configured for primary illumination, while secondary atmosphere LED light sources are distributed in specific patterns for ambient lighting and identification. This local differentiation of light source qualities enables controlled illumination distribution and uniformity without requiring a single overly complex light source system.

Function Achieved in This Case
Improves use efficiency and application range, enabling automatic switching between light modes for better illumination, energy conservation, and reduced traffic accidents through enhanced perception and identification.
Implementation Method 1
light generated by the lightened secondary illuminating LED light sources is refracted and reflected by the light guide element, then is uniformly emitted from the surface of the light guide element
Implementation Method 2
a reflector connected with the LED aluminum substrate is arranged on the opposite side of the light guide element to the aluminum pressing strip, light generated by the lightened secondary illuminating LED light sources is refracted and reflected by the light guide element, then is uniformly emitted from the surface of the light guide element, and then is uniformly emitted after being reflected by the reflector
