Vehicle Grille Lighting with Layered 3D Optical Branding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grille lighting technologies for electric vehicles face limitations in expressing brand identity, leading to increased development and production costs and weight gain due to multiple illuminating devices, while lacking effective three-dimensional visual effects.
Innovation Solution
A lighting device comprising a housing, a lens, a light source, a first pattern layer with three-dimensional patterns, and a second pattern layer with two-dimensional patterns, which combine to create a three-dimensional optical illusion when illuminated, providing both non-illuminated and illuminated images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple illuminating devices are used to achieve grille lighting, then the visual effect and brand identity expression are improved, but the weight and production costs increase
Solution Approach 1:
The patent combines multiple illuminating devices into a single integrated lighting device that uses one light source with multiple pattern layers (first pattern layer with three-dimensional patterns and second pattern layer with two-dimensional patterns) to create the desired visual effects, thereby reducing weight while maintaining illumination quality
Solution Approach 2:
The single lighting device performs multiple functions: it creates three-dimensional optical illusions through the first pattern layer, provides two-dimensional branding patterns through the second pattern layer, and can display different images in illuminated and non-illuminated states, replacing what would traditionally require multiple separate devices

3Device complexity
If conventional lighting solutions are used, then the implementation is simple, but the three-dimensional visual effect and brand identity expression are insufficient
Solution Approach 1:
The patent introduces three-dimensional patterns in the first pattern layer that create optical illusions and depth perception when illuminated, transforming conventional two-dimensional lighting into multi-dimensional visual experiences that enhance brand identity expression
Solution Approach 2:
The lighting device uses composite structure with multiple pattern layers (first pattern layer with three-dimensional patterns and second pattern layer with two-dimensional patterns) made of light-transmitting materials, combining different functional layers to achieve both simple implementation and superior three-dimensional visual effects
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device enhances brand identity and product quality by offering a distinctive three-dimensional image and natural visual effects, reducing complexity and costs by integrating multiple functions into a single unit.
Implementation Method 1
a light source installed in the housing and configured to emit light toward the lens; a first pattern layer arranged between the light source and the lens and provided with one or more first pattern portions
Implementation Method 2
The first pattern layer may include a three-dimensional pattern externally recognizable through the lens. The three-dimensional pattern may be implemented as a three-dimensional image when the light source is turned on
Implementation Method 3
The second pattern layer may include two-dimensional patterns externally recognizable through the lens. The two-dimensional patterns may have different levels of transparency
