Solution Overview

Problem

Existing lighting devices for motor vehicles do not effectively combine conventional lighting functions with the ability to indicate the vehicle's origin, often requiring additional components and increased complexity.

Innovation Solution

A lighting device with a housing and lens that incorporates a brand emblem component partially covering the lens, utilizing a separate circuit board with light sources and a frame to create a light chamber for backlighting, sharing power supply with existing lighting functions and using existing components to reduce complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a bulb is disposed in each reflector segment to illuminate specific sections of the road, then the road can be divided into different sections with different luminous intensities, but the structure becomes more complex and the number of bulbs increases

Engineering Contradiction:
Improvesectional illumination controlVSAvoidnumber of bulbs
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

A single bulb is designed to serve multiple functions by illuminating multiple sections of the road through the segmented reflector structure, replacing what would traditionally require multiple bulbs. The bulb acts as a universal light source for the entire headlight assembly.

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

Solution Approach 2:

Multiple reflector segments are merged into a single integrated headlight housing structure, allowing one bulb to illuminate all sections. The functional elements (reflector segments, bulbs, housing) are combined into a unified assembly rather than separate components.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If traditional headlight assemblies are replaced, then new functions and features can be added, but the cost of purchase and installation increases

Engineering Contradiction:
Improvefunctional flexibilityVSAvoidmanufacturing and installation cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The headlight assembly is segmented into modular components (reflector segments, bulb housing, mounting structures) that can be manufactured separately and assembled. This modular approach enables flexible configuration options while maintaining manufacturing efficiency and reducing overall system cost.

Inventive Principle:
Principle #1Segmentation

3Ease of manufacture

If the headlight assembly is designed as a single integrated unit, then manufacturing and installation are simplified, but flexibility in configuring different functional elements is reduced

Engineering Contradiction:
Improveassembly simplicityVSAvoidconfiguration flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The headlight assembly is segmented into modular components (reflector segments, bulb housing, mounting structures) that can be manufactured separately and assembled. This modular approach enables flexible configuration options while maintaining manufacturing efficiency and reducing overall system cost.

Inventive Principle:
Principle #1Segmentation

AI summary

The invention relates to a lighting apparatus (1) for a motor vehicle (K), comprising a housing and comprising at least one light panel (11) that closes off the housing to the outside. Light beams from at least one illuminant (13, 15) disposed behind the light panel (11) can pass through the light panel (11) to the outside. The invention proposes that a component (5) comprising a brand logo (M) is held on the light panel (11) on the outside. This is implemented in such a way that the component (5) partly covers the light panel (11).
