Vehicle Grille Lens Assembly for 3D Projection and Lower Weight
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 that projects a three-dimensional image onto the lens, utilizing a translucent film and combining light from the lamp and projector for distinctive lighting effects, controlled by a vehicle electronic component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple illuminating devices are used for grille lighting to achieve three-dimensional lighting effects, then the lighting effect and brand identity expression are improved, but the weight and device complexity increase
Solution Approach 1:
The patent combines the illuminating device and the three-dimensional image projector into a single integrated unit. The projector is positioned at the rear of the outer lens and projects images onto the front surface of the lens, while the illuminating device provides backlighting. This merging eliminates the need for separate lighting components, reducing weight while achieving both illumination and three-dimensional visual effects simultaneously.
2Illumination intensity
If multiple illuminating devices are used for grille lighting to achieve three-dimensional lighting effects, then the lighting effect and brand identity expression are improved, but the device complexity and production costs increase
Solution Approach 1:
The patent integrates the projector and illuminating device within a single outer lens assembly. The projector unit is positioned at the rear of the outer lens, and the illuminating device is arranged to provide light toward the outer lens. This unified structure simplifies the overall device complexity and reduces production costs compared to using multiple separate illuminating devices.
3Adaptability or versatility
If a translucent film is added to the lens to project images, then the three-dimensional image projection capability is improved, but the device complexity increases
Solution Approach 1:
The patent uses a translucent film coupled to the lens onto which the image is projected. This thin film approach allows for versatile image projection capabilities without adding significant structural complexity. The film serves as the projection surface, enabling three-dimensional visual effects while maintaining a relatively simple overall device structure.
4Illumination intensity
If the lighting area is expanded to include the grille, then the visual density and brand identity expression are improved, but the development costs and device complexity increase
Solution Approach 1:
The outer lens assembly serves multiple functions: it acts as the headlight cover, the projection surface for three-dimensional images, and the medium through which illuminated light passes. This multi-functionality allows the lighting area to be expanded to include the grille region without requiring separate dedicated components, thereby reducing development costs while achieving enhanced visual density and brand identity expression.
