Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting systems for vehicle grilles face challenges in efficiently irradiating light through the grille while maintaining design aesthetics, as they require significant installation space and result in heterogeneous light distribution.
Innovation Solution
A lighting apparatus comprising a grille panel with pattern holes, a lens panel for light diffusion and emission, and a housing with a light source, where the lens panel is designed to evenly distribute light and reduce the lighting structure's footprint, using optic portions with projections or grooves for controlled light emission and reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If lights are installed in the rear of the grille for light irradiation to the front, then light can be emitted through the grille, but installation space is required and the lighting structure becomes complex
Solution Approach 1:
The patent combines the light source, lens panel, and housing into an integrated lighting assembly that mounts directly to the grille. The housing supports the lens panel which is positioned to align with grille openings, creating a unified structure that eliminates separate mounting components and reduces overall complexity while maintaining light emission functionality.
Solution Approach 2:
The lens panel serves multiple functions: it focuses light from the light source, distributes light uniformly through the grille openings, and provides structural support for mounting the assembly to the grille. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity.
2Illumination intensity
If lights are installed in the rear of the grille, then light can be irradiated to the front, but significant installation space is required
Solution Approach 1:
The light source is positioned within the housing structure, which in turn supports the lens panel. This nested arrangement allows the light source to be housed compactly within the overall assembly footprint, minimizing the space required for installation on the grille while ensuring light can still be effectively directed forward through the lens and grille openings.
3Illumination intensity
If light is emitted from holes of the grille, then light can be heterogeneously distributed, but the design of the grille is hindered
Solution Approach 1:
The lens panel is designed with specific optical properties in different zones to control light distribution. The lens focuses light in certain areas while allowing uniform distribution in others, creating localized optical characteristics that achieve homogeneous light distribution without compromising the overall grille design and pattern.
Solution Approach 2:
The patent uses the lens panel to change the optical parameters of the light emitted through the grille. By refracting and focusing light, the lens transforms the light distribution pattern from heterogeneous to homogeneous, achieving uniform illumination while preserving the grille's aesthetic design and opening patterns.
