Vehicle Visor Lighting Assembly with Rotating Shield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle visors lack a unified lighting solution that efficiently provides both vanity lighting and dome lighting, with existing systems requiring separate activation and often resulting in inefficient light distribution and increased complexity.
Innovation Solution
A vehicle visor with a integrated lighting device assembly that includes a rotating mechanism and light shield, allowing the same light sources to function as both vanity and dome lights, with the light shield positioning to optimize illumination based on the visor's use position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate vanity light and dome light systems are used, then each lighting function can be independently controlled, but the device complexity and wiring increase
Solution Approach 1:
The patent combines separate vanity light and dome light systems into a single integrated lighting device assembly. The housing contains both light sources and optical components that can provide either vanity lighting or dome lighting functions, reducing wiring complexity and assembly steps while maintaining independent controllability through a single control mechanism.
Solution Approach 2:
The lighting device assembly is designed to perform multiple functions - it can operate as a vanity light when the visor is in the down position, and as a dome light when the visor is in the up position. This multi-functional design eliminates the need for separate dedicated lighting systems for each function.
2Device complexity
If a single lighting device provides both vanity and dome light, then wiring and assembly are simplified, but light distribution efficiency decreases
Solution Approach 1:
The lighting device assembly is segmented into distinct optical components - a first optical component for directing light as vanity illumination and a second optical component for directing light as dome illumination. These segmented components allow optimized light distribution for each specific function while sharing a common housing and light source.
Solution Approach 2:
The patent employs a movable light shield or adjustable optical components that can dynamically redirect light distribution based on the visor position. When the visor is down, light is directed forward for vanity use; when the visor is up, light is redirected upward for dome lighting, maintaining high illumination efficiency for both functions.
3Illumination intensity
If light shield is used to direct illumination, then light distribution is optimized, but device complexity increases
Solution Approach 1:
The light shield is designed to be automatically positioned based on visor movement. The shield's position is passively determined by the visor's up or down position, eliminating the need for independent actuation mechanisms, sensors, or complex control systems. The system self-adjusts light distribution according to its operational state.
