Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle lamps have a unified lighting image shape due to their simple configuration, which limits their aesthetic appeal and requires a large number of light sources to achieve varied lighting patterns, increasing manufacturing costs and complexity.
Innovation Solution
A vehicle lamp design utilizing a light guide and reflector with specific reflection surfaces that form convergent points and patterns, allowing for the creation of differentiated lighting images using a small number of light sources, including isosceles and regular triangles, and patterned images that maintain shape visibility from any angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple configuration with a bulb and reflector is used, then the device complexity is reduced, but the lighting image shape becomes unified and aesthetic appeal is limited
Solution Approach 1:
The reflector is divided into multiple reflection surfaces (first reflection surface, second reflection surface, third reflection surface) with different orientations. Each reflection surface reflects light from specific light sources to create distinct lighting image patterns. This segmentation allows a single reflector structure to generate multiple differentiated lighting patterns without requiring multiple separate lighting devices.
Solution Approach 2:
The reflector structure serves multiple functions simultaneously: it reflects light from different light sources to create various lighting image patterns (triangle, square, circle, etc.), it provides structural support, and it maintains the aesthetic appearance. This multi-functionality allows the same component to achieve pattern differentiation without increasing overall device complexity.
2Adaptability or versatility
If multiple light sources are installed to create varied lighting patterns, then the lighting image pattern variety is improved, but the quantity of light sources and device complexity increase
Solution Approach 1:
The reflector is divided into multiple reflection surfaces (first reflection surface, second reflection surface, third reflection surface) with different orientations. Each reflection surface reflects light from specific light sources to create distinct lighting image patterns. This segmentation allows a single reflector structure to generate multiple differentiated lighting patterns without requiring multiple separate lighting devices.
Solution Approach 2:
Different regions of the reflector (different reflection surfaces) have different reflective properties and orientations tailored to specific light sources. The first reflection surface is positioned to reflect light from first light sources, the second reflection surface for second light sources, and so on. This local differentiation allows each light source to contribute to a specific pattern element, achieving complex patterns with minimal light sources.
3Adaptability or versatility
If indirect reflection is used to create differentiated patterns, then the lighting image pattern variety is improved, but the device complexity increases
Solution Approach 1:
The reflector is divided into multiple reflection surfaces (first reflection surface, second reflection surface, third reflection surface) with different orientations. Each reflection surface reflects light from specific light sources to create distinct lighting image patterns. This segmentation allows a single reflector structure to generate multiple differentiated lighting patterns without requiring multiple separate lighting devices.
Solution Approach 2:
The reflector utilizes curved and angled surfaces to redirect light from the light sources. The reflection surfaces are positioned and shaped to reflect light at specific angles to create the desired geometric patterns (triangles, squares, circles). This use of curved and angled surfaces enables indirect reflection to generate complex patterns while maintaining a relatively simple integrated reflector structure.

AI summary
Disclosed is a vehicle lamp, including a reflector reflecting light of a light guide, wherein the reflector includes a first reflection surface and a second reflection surface forming an inner circumferential surface, together with at least a part of a light emitting surface of the light guide and the inner circumferential surface is converged in a direction opposite to an irradiation direction to form a convergent point. By this configuration, it is possible to reduce manufacturing costs and manufacturing man hour of the vehicle lamp while increasing aesthetic appearance of the vehicle.
