Solution Overview

Problem

Existing vehicle grille lighting technologies face limitations in expressing brand identity, suffer from increased development and production costs, and weight gain due to multiple illuminating devices, and lack effective three-dimensional imaging capabilities.

Innovation Solution

A lighting device comprising an outer lens, projector, and lamp system that projects a three-dimensional image onto a translucent film, controlled by a vehicle electronic component, offering both illuminated and non-illuminated effects and reducing weight through simplified structural design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

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

Engineering Contradiction:
Improvelighting effectsVSAvoidweight
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 ambient lighting and projected imagery without requiring separate heavy components for each function

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lighting device serves multiple functions simultaneously: the lamp provides general illumination of the grille area, the projector displays branded imagery and patterns, and both components work together to create dynamic lighting effects, replacing what would traditionally require multiple dedicated devices

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

2Illumination intensity

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

Engineering Contradiction:
Improvelighting effectsVSAvoidstructural complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent integrates the projector and lamp into a single mounted assembly on the grille, combining what would be separate devices into one unified structure with shared mounting and control infrastructure, thereby reducing overall system complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated lighting device performs multiple functions (ambient illumination and projected imagery) through a single unified system rather than requiring separate dedicated devices for each function, simplifying the overall device architecture

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

3Ease of manufacture

If conventional injection-molded structure is used for lighting effect, then manufacturing is simplified, but three-dimensional imaging capability is lost

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidthree-dimensional imaging capability
Core Design Contradiction:
Ease of manufactureVSManufacturing precision

Solution Approach 1:

The patent replaces the conventional mechanical injection-molded structure with an optical projection system that uses a projector to display images and patterns on the grille surface, substituting physical 3D molding with light-based imaging technology

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system dynamically changes lighting parameters (intensity, pattern, color) through the projector and lamp control to create various three-dimensional visual effects, replacing fixed mechanical structures with adjustable optical parameters

Inventive Principle:
Principle #35Parameter changes
