One-Piece Fender Mirror Mount for Stiffness and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mirror mounts on vehicle fenders lack sufficient stiffness and strength, leading to instability and reduced driver visibility.
Innovation Solution
A one-piece base member with reinforcing ribs and a cross bolt feature that securely attaches to the vehicle fender, providing improved stability and stiffness through a molecularly continuous design that integrates a pivot support for adjustable mirror positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional multi-part mirror support arms are used to mount the mirror, then the mirror can be attached to the fender, but the mount lacks sufficient stiffness and strength
Solution Approach 1:
The patent combines multiple separate mounting components (base member, support arms, fasteners) into a single integrated one-piece base member with molecularly continuous structure. This merging eliminates weak joints between parts and provides unified structural strength while reducing the number of separate components that need to be assembled and maintained.
Solution Approach 2:
The one-piece base member incorporates segmented reinforcing ribs that divide the structural load into multiple localized reinforcement zones. These ribs segment the base member's structure to provide targeted strength enhancement in critical areas without requiring additional separate support components.
2Stability of the object's composition
If traditional L-shaped base members with separate brackets are used, then the mirror can be mounted, but the mount lacks sufficient stiffness
Solution Approach 1:
The patent merges the base member, support arms, and reinforcing elements into a single molecularly continuous structure. This integration ensures that loads are distributed throughout the entire structure rather than concentrated at joints between separate components, providing both stiffness and strength simultaneously.
Solution Approach 2:
The one-piece base member incorporates locally varying thickness and strategically placed reinforcing ribs that concentrate material where structural demands are highest. This local quality enhancement provides targeted stiffness and strength reinforcement without uniformly increasing the entire structure's mass.
3Ease of manufacture
If the base member is simply clamped to the fender, then installation is simple, but fender stability and driver visibility are not improved
Solution Approach 1:
The patent integrates multiple stabilization features directly into the one-piece base member structure, including reinforcing ribs and optimized attachment geometries. This merging provides enhanced reliability and fender stability without requiring separate stabilization components or complex assembly procedures.
Solution Approach 2:
The base member extends into the compartment under the hood in a third dimension, providing additional attachment points and structural anchoring beyond the simple surface clamp. This dimensional extension enhances fender stability and driver visibility by creating a more robust three-dimensional mounting structure.

AI summary
A mirror mount that mounts a mirror to a fender of a vehicle includes a base member having a first end generally vertical when the base member is affixed to a fender and arranged to receive a fastener passing through the first end, through the fender, and into the base member so as to fasten the base member to the fender, a second end, a side portion extending between the first end and the second end and having a contour that follows an exterior profile of the fender, and a reinforcement reinforcing the first end.
