Vehicle Turn Signal Light Guide Layout for Uniform Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turn signal systems face challenges in limited space availability, leading to non-uniform illumination due to dark spots near the light tube entrance and the need to integrate the power source and light tube in the same plane.
Innovation Solution
A turn signal system with a light source and a light tube separated in different planes, interconnected by flexible or rigid light guides, which are bent to form elbow or 180-degree bends, and coupled through apertures in the light tube, ensuring uniform illumination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the power source and light tube are placed in the same plane to simplify the structure, then the device complexity is reduced, but the space availability becomes insufficient due to limited size constraints
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement to a three-dimensional spatial configuration by routing the light guide through the hollow interior of the power source. This dimensional change allows the light tube to be positioned in a different plane from the power source while maintaining compact integration, effectively resolving the space constraint issue.
2Area of stationary object
If the light source is placed close to the light tube entrance to reduce space, then the space constraint is satisfied, but non-uniform illumination with dark spots occurs near the light tube entrance
Solution Approach 1:
The patent introduces a light guide as an intermediary component between the light source and the light tube. This light guide efficiently channels and distributes light from the light source along its length, ensuring uniform illumination of the light tube without requiring the light source to be positioned at the light tube entrance, thus eliminating dark spots while maintaining compact space utilization.
