Solution Overview
Problem
Vehicle door mirrors with integrated lighting systems face challenges in maintaining effective visual recognition of light while preserving the mirror's field of view, as existing designs either compromise light visibility or reduce the reflection surface area.
Innovation Solution
A vehicle door mirror design featuring a gap between the mirror body and the holder's flange, where a lighting unit's light emitting portion is positioned, allowing for improved light recognition and minimizing the reduction of the reflection surface area, thus maintaining an effective field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the inner circumferential edge of the flange is increased in width toward the center of the reflection surface to form an opening window portion, then the visual recognition properties of light are improved, but the reflection surface area is reduced and the effective field of view decreases
Solution Approach 1:
The light emitting portion is positioned in the radial direction between the mirror body circumferential edge and the holder flange, utilizing the radial dimension to place the light source without encroaching on the reflection surface area in the axial direction. This dimensional repositioning allows light emission while preserving the mirror's field of view.
Solution Approach 2:
The space between the mirror body and holder flange is segmented into a specific radial gap that accommodates the light emitting portion. This segmentation creates a dedicated space for lighting without compromising the integrity or area of the reflection surface.
2Device complexity
If the light emission surface is disposed laterally of the mirror body, then the structure is simplified, but the driver cannot directly visually recognize the emitted light reducing emergency warning effectiveness
Solution Approach 1:
The light emitting portion is repositioned from a lateral position to a radial position between the mirror body and holder flange. This dimensional change aligns the light emission direction with the driver's line of view, enabling direct visual recognition while maintaining structural simplicity.
Solution Approach 2:
The radial gap between the mirror body circumferential edge and holder flange serves as an intermediary space that positions the light emitting portion optimally. This intermediate positioning allows the light to be directly visible to the driver without requiring complex optical systems.

AI summary
In a vehicle door mirror, Between a circumferential edge of a mirror body 2 of a reflection mirror unit 1 in which a lighting unit 10 is incorporated and a flange on a circumferential edge 3a of a holder 3, a gap 4 for light emission is provided in a state in which the circumferential edges thereof are partially spaced from each other in a radial direction, and in the gap, a light emitting portion 10L of the lighting unit 10 is secondarily disposed. In this manner, a driver can directly visually recognize light that is emitted from the light emitting portion 10L, and a decrease in reflection area of the mirror body 2, which is caused by forming the gap 4, can be restrained to its required minimum level, making it possible to ensure an effective field of view of the door mirror.
