Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle light apparatuses lack distinctiveness in combining decorative and functional aspects, such as high/low beam, turn signal, and daytime running lights, necessitating a novel design that differentiates them from conventional models.
Innovation Solution
The vehicle light apparatus incorporates a light-emitting member, a light-entering lens with incident structures, and a light-exiting lens featuring reflecting surfaces arranged as hyperboloid curved surfaces, which refract and reflect light rays to create distinct focal regions, allowing for unique light beam distribution and projection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If conventional vehicle light apparatus designs are used, then manufacturing and assembly are straightforward, but the apparatus lacks visual distinctiveness and aesthetic appeal
Solution Approach 1:
The optical lens is divided into multiple functional regions: a light-entering portion with incident structures for receiving and initially directing light, and a light-exiting portion with reflecting surfaces for secondary light direction. This segmentation allows each region to be optimized for its specific function while collectively creating the desired complex light distribution pattern and visual effect
Solution Approach 2:
The light-exiting portion incorporates reflecting surfaces with curved geometries, specifically utilizing hyperboloid surfaces that extend in a top-bottom direction perpendicular to the front-rear direction. These curved surfaces create distinctive light reflection patterns and contribute to the apparatus's visual distinctiveness while maintaining functional efficiency
2Adaptability or versatility
If simple light distribution patterns are used, then the optical system is easier to design, but the apparatus cannot provide both decorative and functional lighting effects
Solution Approach 1:
The optical lens is designed to simultaneously perform multiple functions: it directs light for functional illumination (high/low beam, turn signal, daytime running light) while also creating decorative lighting effects through its specialized incident structures and hyperboloid reflecting surfaces. This multi-functionality allows a single optical component to satisfy both aesthetic and performance requirements
Solution Approach 2:
Different regions of the optical lens are assigned different functional properties: the light-entering portion features incident structures optimized for light reception and initial direction, while the light-exiting portion incorporates hyperboloid reflecting surfaces for specific light reflection patterns. This local differentiation enables the system to achieve complex light distribution and decorative effects without requiring an entirely complex system architecture
3Manufacturing precision
If conventional lens designs are used, then manufacturing is simpler, but the light beam distribution lacks uniqueness and optical performance is limited
Solution Approach 1:
The light-exiting portion utilizes hyperboloid reflecting surfaces with specific curvature characteristics that extend in the top-bottom direction. These curved surfaces provide precise light reflection control for achieving unique beam distribution patterns while the hyperboloid geometry can be manufactured using standard rotational molding or injection molding techniques for optical components

Implementation Method 1
adapted for refracting or reflecting the light rays entering the incident structures, such that extension lines of the light rays refracted or reflected by the incident structures intersect with a first focal region
Implementation Method 2
Each of the reflecting surfaces serves as one of two curved surfaces of a hyperboloid, such that the extension lines of the light rays reflected by the reflecting surface intersect with a second focal region

AI summary
A vehicle light apparatus includes a light-emitting member, a light-entering lens including juxtaposed incident structures, and a light-exiting lens. The incident structures are adapted for refracting or reflecting the light rays from the light-emitting member, such that extension lines of the light rays refracted or reflected by the incident structures intersect with a first focal region. The light-exiting lens extends from the light-entering lens, and includes a reflecting portion and a light-exiting portion opposite to the reflecting portion. The reflecting portion has spaced-apart reflecting surfaces adapted for reflecting the light rays refracted or reflected by the incident structures. Each reflecting surface serves as one of two curved surfaces of a hyperboloid, such that the extension lines of the light rays reflected by the reflecting surface intersect with a second focal region, and that the first focal region and the second focal region respectively overlap two focal points of the hyperboloid.
