Rearview Mount Ramps Prevent Housing Impact During Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rearview assemblies for vehicles often break during safety testing due to contact with mounting brackets, leading to unsafe conditions in collisions.
Innovation Solution
A mount with projecting ramps that changes the orientation of the rearview assembly upon detachment, preventing impact with the mounting bracket by sliding and rotating the assembly to avoid contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rearview assembly is configured to slide directly off the mounting bracket, then the removal process is simple, but the housing impacts the bracket causing breakage and safety failures
Solution Approach 1:
The projecting ramp is pre-configured on the mount to automatically activate upon detachment initiation. As the mount slides off the bracket, the ramp projects forward in advance to redirect the housing trajectory, preventing impact before it occurs. This preliminary geometric configuration ensures safe removal without requiring additional active components.
Solution Approach 2:
The projecting ramp acts as an intermediary element between the mount and the housing. It mediates the detachment process by redirecting the housing away from the bracket path, serving as a protective interface that prevents direct contact between the housing and bracket during removal.
2Stability of the object's composition
If the mount is made secure and stable during operation, then the rearview assembly is firmly held, but the detachment process becomes difficult and may cause impact
Solution Approach 1:
The mount transitions from a static secure connection to a dynamic detachment process. During normal operation, the mount maintains stable engagement with the bracket. During removal, the projecting ramp dynamically redirects the housing trajectory, allowing smooth detachment without impact. This dynamic geometric feature enables both secure operation and easy removal.
3Productivity
If the housing is oriented directly toward the bracket during removal, then the detachment path is straightforward, but the housing contacts and breaks upon separation
Solution Approach 1:
The projecting ramp is pre-configured to redirect the housing trajectory as soon as detachment begins. This preliminary geometric configuration ensures that the housing is redirected away from the bracket path before separation completes, maintaining both speed and integrity.
Solution Approach 2:
The projecting ramp changes the orientation parameter of the housing during detachment. By redirecting the housing at an angle away from the bracket, the ramp modifies the trajectory parameters to prevent contact while maintaining efficient removal speed.

AI summary
A rearview device comprises a rearview assembly having a display surface and a housing configured to support the display surface; and a mount configured to connect to and support the housing. The mount may be slidably securable in a first direction to a mounting bracket and slidably detachable in a second direction from the mounting bracket. The mount may comprise at least one projecting ramp, the at least one projecting ramp configured to, upon the mount being slidably detached from the mounting bracket, change the orientation of the housing relative to the bracket to prevent the housing from impacting the mounting bracket.
