Thin Sun Visor Lighting via Integrated Reflective Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sun visor bodies with light sources are complex to produce, thick in design, and provide unsatisfactory illumination for vehicle seat occupants, particularly for thin sun visors.
Innovation Solution
A sun visor body incorporating a mirror and light sources, where the light sources are focused and directed via a reflective surface on a pivoting cover that can be adjusted to provide targeted illumination to the occupant's face, while maintaining a compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional light sources and mirrors are incorporated into the sun visor body, then illumination function is provided, but the sun visor becomes thick and complex to produce
Solution Approach 1:
The mirror cover and reflector are merged into a single integrated component. The reflector is formed as an integral part of the mirror cover, eliminating the need for separate reflector components and reducing overall thickness while maintaining illumination function
Solution Approach 2:
The mirror cover serves multiple functions: it protects the mirror, acts as a reflector for light redirection, and provides structural support. This multi-functionality reduces the number of separate components needed, simplifying production and reducing thickness
2Length of stationary object
If conventional light sources are used in thin sun visors, then illumination is provided, but the illumination quality is unsatisfactory
Solution Approach 1:
The reflector is designed with specific local properties: a highly reflective surface on the inner side of the mirror cover that is optimized for redirecting light onto the user's face. This localized reflective quality ensures effective illumination even in thin visor designs
Solution Approach 2:
The reflector acts as an intermediary between the light source and the user's face. It redirects and distributes light from the LED source to illuminate the face area effectively, achieving satisfactory illumination quality in thin visor configurations
3Illumination intensity
If multiple components (mirror, light sources, reflector) are incorporated into the sun visor, then illumination function is achieved, but device complexity increases
Solution Approach 1:
The mirror cover and reflector are merged into a single integrated component. The reflector is formed as an integral part of the mirror cover, eliminating the need for separate reflector components and reducing overall thickness while maintaining illumination function
Solution Approach 2:
The mirror cover serves multiple functions: it protects the mirror, acts as a reflector for light redirection, and provides structural support. This multi-functionality reduces the number of separate components needed, simplifying production and reducing thickness
