Outer Mirror Indicator Layout for Light Visibility and Reflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional outer mirrors with light-emitting indicators may fail to provide adequate visibility of objects due to the absence of reflective films in marked regions, leading to potential misrecognition by drivers.
Innovation Solution
The implementation of a light transmission portion on the mirror surface, comprising multiple linear transmission portions aligned in a vertical direction and forming a closed planar figure, such as a triangle, to enhance visibility by allowing light emission through these portions while maintaining reflective functionality in adjacent areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a reflective film is not provided in the region where the outer mark and inner mark are located to allow light transmission, then the indicator can emit light through the mirror surface, but the visibility of external objects in that region deteriorates
Solution Approach 1:
The light transmission portion is segmented into multiple linear transmission portions that are aligned vertically. This segmentation allows the indicator to emit light effectively while the spaces between the linear portions maintain reflective film, enabling object visibility. The segmented structure resolves the contradiction by creating distinct functional zones within the same region.
Solution Approach 2:
Different portions of the mirror surface have different optical properties: the linear transmission portions allow light transmission for indicator visibility, while the regions between them maintain reflective film for object recognition. This local differentiation of quality resolves the contradiction by allowing both light transmission and reflection to coexist in different locations within the same overall region.
2Reliability
If the light transmission portion is formed with multiple linear transmission portions aligned vertically, then object visibility is improved through maintained reflective surfaces, but the device structure becomes more complex
Solution Approach 1:
The light transmission portion is divided into multiple linear transmission portions arranged vertically. While this segmentation improves object visibility by preserving reflective areas, it does increase structural complexity. However, the linear arrangement simplifies the overall design compared to more complex patterns, as it requires only vertical alignment rather than intricate geometric configurations.
3Illumination intensity
If the linear transmission portions extend horizontally and are aligned vertically, then light emission and object visibility are optimized, but the manufacturing precision requirements increase
Solution Approach 1:
The linear transmission portions have specific local characteristics: they extend horizontally but are aligned vertically in a structured pattern. This local quality optimization improves light transmission efficiency while the regular vertical alignment pattern simplifies manufacturing compared to irregular patterns, as it requires consistent spacing and orientation rather than complex positioning tolerances.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves object visibility by ensuring that light is effectively transmitted and reflected, enhancing the driver's recognition of rear lateral objects, even under various viewing angles and lighting conditions.
Implementation Method 1
a light emission portion disposed on a side opposite to an exposure surface side being exposed to the outside of the mirror member in such a way that the light emission portion can emit light through the light transmission portion
Implementation Method 2
a reflective film is not provided in positions of the outer mark and the inner mark, and light is thus transmitted through the inside and the outside of the door mirror in the positions

AI summary
An indicator provided on an outer mirror of a vehicle includes: a light transmission portion formed in a mirror surface portion of a mirror member of the outer mirror; and a light emission portion disposed on a side opposite to an exposure surface side being exposed to the outside of the mirror member in such a way that the light emission portion can emit light through the light transmission portion. The light transmission portion includes a plurality of linear transmission portions each extending in a horizontal direction and also being aligned in a vertical direction.
