Integrated Base Bracket for Vehicular Side Mirror
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rearview mirror assemblies for vehicles often require complex and costly assembly processes, with multiple components and redundant structures that complicate manufacturing and installation, particularly when integrating features like powerfold mechanisms and blind spot indicators.
Innovation Solution
An integrated base bracket system for exterior rearview mirrors is designed, where the mounting base is encased within the vehicle door's sheet metal components, eliminating the need for an outer base component and simplifying assembly by using a bayonet mount for the mirror head, which can be attached without tools, and incorporating features like a heater pad for defogging and blind spot indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate components are used for the mirror mounting system, then the mirror can be securely mounted to the door, but the assembly process becomes complex and costly with redundant structures
Solution Approach 1:
The base bracket is integrated directly into the door structure, merging the mounting base with the door itself. This eliminates separate mounting components and reduces assembly steps while maintaining secure mirror attachment to the door
2Reliability
If an outer base component is added to encase the mounting base, then the mirror assembly appears more complete and secure, but the number of components increases and assembly becomes more difficult
Solution Approach 1:
The outer base component is merged with the door structure itself, forming an integrated mounting system. The door serves as both the structural support and the enclosing housing, eliminating the need for separate outer base components and simplifying manufacturing
3Reliability
If traditional mounting methods are used for the mirror head, then secure attachment is achieved, but tool-based installation increases assembly time and manufacturing cost
Solution Approach 1:
The mirror head mounting mechanism uses a dynamic bayonet-style quick-connect interface that allows tool-free attachment and detachment. This enables secure mounting while dramatically reducing assembly time compared to traditional threaded or riveted connections

AI summary
A vehicular exterior rearview mirror system includes a vehicle door having an inner sheet metal portion and an outer sheet metal portion. A base bracket includes (i) a body portion, (ii) a mirror mounting portion that extends from the body portion and (iii) an attaching portion that extends from the body portion. The attaching portion is attached at the inner sheet metal portion of the vehicle door. The body portion of the base bracket is partially disposed at an interior portion of the vehicle door between the inner sheet metal portion and the outer sheet metal portion. The mirror mounting portion extends outboard of the outer sheet metal portion from the body portion. A mirror head is attached at the mirror mounting portion of the base bracket. The mirror head includes a mirror reflective element.
