Vehicle Lamp Module Mirror Reflector Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rear combination lamps in vehicles are limited in design flexibility and visibility due to high manufacturing costs and limitations in implementing 3D-effect designs, especially when using multiple LEDs and optic lenses, which restricts exterior design quality and visibility from different angles.
Innovation Solution
A lamp module that employs a mirror reflector with a predetermined curvature to extend the image of an inner lens, allowing for a large-area lighting effect and 3D-effect designs, while reducing the number of light sources needed, thereby saving manufacturing costs and enhancing design freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If multiple LEDs and optic lenses are used to improve exterior design, then design quality is improved, but manufacturing cost increases
Solution Approach 1:
The patent uses a mirror reflector to create a reflected image of the inner lens, effectively copying the lens appearance to extend the visual design area without adding physical lens components, thereby improving exterior design quality while avoiding the cost of additional optic lenses
Solution Approach 2:
The mirror reflector serves multiple functions: it extends the visual image area, creates 3D effects, and eliminates the need for additional light sources and optic lenses, providing a cost-effective solution that achieves complex design goals with a single component
2Adaptability or versatility
If individual inner lens modules are adopted to improve design flexibility, then design freedom is improved, but manufacturing cost increases
Solution Approach 1:
The mirror reflector is designed with variable curvature that can be adjusted to create different lighting patterns and 3D effects, providing design flexibility comparable to multiple individual lens modules while using a single universal component that reduces manufacturing cost
3Shape
If a lens is bent to the front of the vehicle to improve exterior design, then design quality is improved, but visibility from different angles is limited
Solution Approach 1:
The mirror reflector is formed with a predetermined variable curvature that reflects light to create large-area lighting images visible from multiple angles, maintaining exterior design quality while significantly improving visibility compared to front-bent lens designs
