Vehicle Grille Lighting Assembly for 3D Brand Image Projection

Solution Overview

Problem

Existing vehicle grille lighting technologies face limitations in expressing brand identity, incur high development and production costs, and result in weight gain due to multiple illuminating devices.

Innovation Solution

A lighting device comprising an outer lens, a projector, and a lamp, where the projector projects an image onto a translucent film on the lens, and the lamp emits light to create a three-dimensional image, controlled by a controller, offering both illuminated and non-illuminated effects and reducing weight through structural simplification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If multiple illuminating devices are used for grille lighting, then lighting effects are enhanced, but weight increases

Engineering Contradiction:
Core Design Contradiction:
Illumination intensityVSWeight of moving object

Solution Approach 1:

The patent combines the projector and lamp into a single integrated lighting device assembly mounted on the grille, merging multiple illuminating functions into one unified structure that provides both pattern projection and ambient illumination without requiring separate mounting systems

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lighting device performs multiple functions simultaneously: the projector creates branded lighting patterns while the lamp provides general illumination, and the controller manages different lighting modes (welcome, driving, parking) to deliver versatile lighting effects from a single device

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

2Illumination intensity

If multiple illuminating devices are used for grille lighting, then lighting effects are enhanced, but device complexity increases

Engineering Contradiction:
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent integrates the projector, lamp, and controller into a single modular assembly that can be mounted as one unit on the grille, reducing installation complexity and simplifying the overall vehicle lighting system architecture

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The controller provides universal control over multiple lighting functions and modes, managing both the projector and lamp through a single control interface that handles welcome lighting, driving lighting, and parking lighting scenarios

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

3Illumination intensity

If multiple illuminating devices are used for grille lighting, then lighting effects are enhanced, but development and production costs increase

Engineering Contradiction:
Core Design Contradiction:
Illumination intensityVSEase of manufacture

Solution Approach 1:

The patent combines the projector and lamp into a single integrated assembly that can be manufactured and installed as one unit, reducing development costs associated with coordinating multiple separate devices and simplifying production logistics

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lighting device provides multiple lighting functions (projector patterns, lamp illumination, various modes) from a single product, improving cost-effectiveness by delivering enhanced lighting effects without proportionally increasing development and production expenses

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