Solution Overview

Problem

Existing vehicle headlamp optical systems face challenges in miniaturization and diversified design due to limitations in reducing the size of vertical light openings for high-beam and low-beam modules, and interference with traditional dimming mechanisms, which restricts design space and aesthetic appeal.

Innovation Solution

A vehicle headlamp optical system featuring narrow and long light distribution lenses with multiple modules, including high-beam, main low-beam, and auxiliary low-beam modules, integrated optical elements, and a compact dimming system that allows for up-down and left-right movement, enabling miniaturization and diversified design without increasing module size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If traditional lens or reflecting mirror structures are used in vehicle headlamp optical systems, then high-beam and low-beam lighting functions can be achieved, but the vertical opening sizes of light outlets cannot be reduced, limiting miniaturization

Engineering Contradiction:
Improvesize of vertical opening of light outletVSAvoidlighting function capability
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The patent divides the headlamp optical system into multiple independent modules (high-beam module, main low-beam module, auxiliary low-beam module), each with its own optical elements. This segmentation allows each module to be optimized independently for compactness while maintaining overall lighting functionality, directly addressing the contradiction between miniaturization and functional versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from traditional large vertical opening designs to a modular arrangement where optical elements are positioned at intervals along the length direction of narrow and long light distribution lenses. This dimensional reorganization allows the system to achieve required lighting functions through extended horizontal arrangement rather than vertical stacking, enabling significant reduction in vertical opening size.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Volume of moving object

If miniaturization is pursued to reduce headlamp size, then design space becomes smaller, but traditional dimming mechanisms interfere with the housing and cannot achieve dimming function

Engineering Contradiction:
Improvesize of headlampVSAvoiddimming function
Core Design Contradiction:
Volume of moving objectVSEase of operation

Solution Approach 1:

The patent replaces traditional mechanical dimming mechanisms with a dynamic control approach where the housing itself can be adjusted or deformed to achieve dimming. This dynamic solution allows the compact headlamp structure to maintain dimming capability without requiring additional space-consuming mechanical components, resolving the contradiction between miniaturization and operational functionality.

Inventive Principle:
Principle #15Dynamics
