Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
ImprovefunctionalityVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If traditional headlights are used, then the structure is simple, but perception and identification between pedestrians and vehicles cannot be achieved

Engineering Contradiction:
ImprovesafetyVSAvoidstructure
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #32Color changes

3Illumination intensity

If single light source configuration is used, then the structure is simple, but illumination uniformity and distribution control cannot be achieved

Engineering Contradiction:
Improveillumination uniformityVSAvoidstructure
Core Design Contradiction:
Illumination intensityVSDevice complexity

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.

Inventive Principle:
Principle #3Local quality
