Solution Overview

Problem

The installation of vertical headlamp modules on automotive vehicles often results in decreased lighting performance, including non-optimal uniformity and intensity, which is a concern for manufacturers seeking an aesthetic upgrade.

Innovation Solution

Designing a vertical headlamp module with lenses taller than wide, allowing for stacked lighting units that maintain lighting performance through adaptable lighting functions and focal point adjustments, even when inclined.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If vertical headlamp modules are installed to achieve aesthetic appearance, then visual appearance is improved, but lighting performance deteriorates

Engineering Contradiction:
Improvevisual appearanceVSAvoidlighting performance
Core Design Contradiction:
ShapeVSIllumination intensity

Solution Approach 1:

The headlamp module is divided into multiple separate lighting units (first lighting unit, second lighting unit, etc.), each with its own lens and light exit area. This segmentation allows each unit to be optimized for specific lighting functions while collectively achieving the desired vertical aesthetic appearance. Each lighting unit can be independently configured to contribute to overall lighting performance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent transitions from conventional horizontal headlamp modules to a vertical configuration by arranging lighting units stacked above one another in the vertical dimension. This dimensional change achieves the desired aesthetic appearance while maintaining lighting performance through proper optical design of each vertical unit.

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

2Shape

If vertical headlamp modules are installed, then aesthetic appearance is improved, but uniformity of lighting deteriorates

Engineering Contradiction:
Improvevisual appearanceVSAvoiduniformity of lighting
Core Design Contradiction:
ShapeVSManufacturing precision

Solution Approach 1:

Each lighting unit is designed with specific local characteristics - different lenses (10, 26) with different optical properties, different light exit areas, and different arrangements of light elements. This local quality differentiation allows each unit to contribute specifically to achieving uniform lighting across the entire vertical module while maintaining the aesthetic vertical appearance.

Inventive Principle:
Principle #3Local quality
