Vehicle Mirror Pivotable Light for Multi-Function Illumination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Exterior rearview mirrors lack the ability to perform multiple light functions and direct light in various directions efficiently, limiting their utility for periphery illumination, turn indication, and other functions.
Innovation Solution
The exterior rearview mirror features a pivotable light system with a combined adjustment mechanism, allowing the light to be directed in multiple planes and used for various functions such as turn indication, position lighting, and lateral periphery illumination, with the light support and reflector being pivotable around a central axis within the mirror housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed light system is used in the mirror housing, then the structure is simple and cost-effective, but the light direction cannot be adjusted for multiple functions
Solution Approach 1:
The light system is made dynamically adjustable through a pivotable mounting mechanism that allows the light to be oriented in different directions. The light can be adjusted between a first orientation for illuminating the rearward lateral periphery and a second orientation for other lighting functions, transforming a static system into a dynamic one that adapts to different operational requirements.
Solution Approach 2:
A single light unit is designed to perform multiple functions by adjusting its orientation. The same light can serve as a position light, turn indicator, or periphery illuminator depending on its angular position, eliminating the need for separate fixed lights for each function and achieving multi-functionality with a single component.
2Adaptability or versatility
If multiple separate lights are installed for different functions, then each light function is optimized, but the device complexity and number of components increase
Solution Approach 1:
One light unit is designed to replace multiple separate lights by performing various functions through angular adjustment. The light can be oriented to illuminate the rearward lateral periphery, serve as a position light, or function as a turn indicator, allowing a single component to fulfill the roles of what would traditionally require multiple dedicated lights.
Solution Approach 2:
Multiple light functions that would traditionally require separate light units are merged into a single adjustable light system. The consolidation reduces the total number of components while maintaining functional coverage, as the same light source serves multiple purposes depending on its orientation within the mirror housing.
3Reliability
If the mirror head is folded towards the vehicle for parking, then the mirror retracts safely, but the light emission direction changes due to the slanted position
Solution Approach 1:
The light mounting is designed to be pivotable relative to the mirror head, allowing dynamic adjustment of the light's orientation. When the mirror head is folded to a slanted parking position, the light can be independently repositioned to maintain its intended emission direction, compensating for the mirror's angular change and ensuring reliable light function regardless of mirror position.

Function Achieved in This Case
This design enables a large illuminated area with a single light source, allowing for multiple functions like turn indication, position lighting, and day running lights, while maintaining flexibility in light direction, even when the mirror is folded for parking, thus enhancing safety and functionality.

AI summary
The exterior rearview mirror is comprised of a mirror housing, having at least one transparent light window, behind which at least one light is disposed, comprising at least one illuminant, whose light passes through the light window to the outside. In order provide the exterior rearview mirror so that different light functions and light directions can be performed by the light, at least a portion of the light is disposed adjustable.
