Vehicle Mirror Turn Signal Light Window Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exterior rear view mirrors with colored light windows face issues of reduced light emission due to absorption, affecting the appearance and functionality of turn signal lights, which must adhere to specific color regulations.
Innovation Solution
Incorporating a colored element, such as a translucent pigmented screen, that influences the appearance without altering the legally defined turn signal light color, ensuring the light window remains fully transparent and maintains optimal light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a colored light window is used to achieve a customized mirror appearance, then the aesthetic appearance is improved, but the light emission is reduced due to absorption in the colored material
Solution Approach 1:
The patent divides the light window into two functionally separate components: a transparent light window for optimal light transmission and a colored housing for aesthetic appearance. This segmentation allows each component to fulfill its specific function without compromising the other - the light window remains fully transparent to maximize light emission while the housing provides the desired colored appearance.
Solution Approach 2:
The patent introduces a reflector as an intermediary element between the light source and the light window. The reflector directs light toward the transparent light window, ensuring that light does not pass through the colored housing material which would cause absorption. Instead, light is reflected and transmitted through the transparent light window, maintaining high light emission while the colored housing provides aesthetic appearance.

If a colored lens is used to give the turn signal a specific color, then the appearance is improved, but the light emission is reduced due to absorption
Solution Approach 1:
The patent segments the turn signal assembly into a transparent lens for light transmission and a colored housing element for appearance. The transparent lens ensures maximum light emission while the colored housing provides the desired aesthetic appearance, resolving the contradiction between appearance and light emission.
Solution Approach 2:
The patent applies different properties to different parts of the turn signal assembly: the lens area is kept transparent to maximize light transmission, while the housing areas are colored to provide aesthetic appearance. This local differentiation of material properties allows each region to optimize its specific function - light transmission where needed and appearance where visible.
3Shape
If the light window is made colored to match the turn signal color, then the appearance is improved, but the light emission decreases due to absorption in the light window
Solution Approach 1:
The patent clearly segments the appearance function from the light transmission function by using a transparent light window and a colored housing. The light window remains transparent to ensure optimal light emission, while the housing provides the colored appearance, eliminating the need to compromise light transmission for aesthetic purposes.
Solution Approach 2:
The reflector acts as an intermediary that directs light through the transparent light window rather than through any colored material. This intermediary mechanism ensures that light transmission is optimized through the transparent window while the colored housing elements provide aesthetic appearance without interfering with light emission.

Function Achieved in This Case
This solution allows for a customizable appearance of the mirror while maintaining compliance with turn signal light color regulations and enhancing light visibility, even in bright conditions, by using a colored screen integrated into the turn signal device.
Implementation Method 1
the light emitted by the incandescent light source or LED penetrates through the light window to the exterior

AI summary
The invention is related to an exterior rear-view mirror for vehicles, having a mirror head (1) with a housing (2) in which an adjustable mirror pane is positioned and in which at least one light source (5) is arranged which is located in an area behind a light window (3) of the housing (2). Light window (3) is part of a turn light signal device which comprises a colour screen (7) to influence colour appearance to turn light signal not activated.
