Liftgate Camera Mount With Adjustable Rearview Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of a liftgate in a vehicle often requires the removal of a tailgate and/or bumper, which may necessitate the relocation of OEM backup cameras and proximity sensors, leading to the need for additional devices or vehicle modifications.
Innovation Solution
A liftgate system with integrated brackets and apertures for mounting OEM cameras and proximity sensors, allowing them to be relocated without additional modifications, and adjustable camera angles for enhanced rearview visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a liftgate is installed in a vehicle requiring removal of tailgate and/or bumper, then rearview visibility function is transferred to liftgate, but additional devices or vehicle modifications are needed for camera and sensor installation
Solution Approach 1:
The patent combines the camera mount and sensor mounts into a single integrated bracket assembly that attaches to the liftgate. This merging of multiple mounting functions into one component eliminates the need for separate installation hardware and reduces overall system complexity while maintaining all necessary rearview visibility functions.
Solution Approach 2:
The bracket assembly is designed to serve multiple functions simultaneously: it mounts the camera, mounts multiple proximity sensors, and attaches to the liftgate structure. This multi-functional design eliminates the need for separate mounting solutions for each component, thereby reducing device complexity while preserving adaptability.
2Reliability
If OEM backup camera and proximity sensor are relocated to liftgate, then original equipment functionality is preserved, but installation complexity increases
Solution Approach 1:
The bracket assembly is pre-configured with all necessary mounting features, apertures, and attachment points before installation. The camera and sensors are designed to interface with standardized features on the bracket, allowing for straightforward installation without complex alignment or custom fabrication during the installation process.
Solution Approach 2:
The bracket assembly serves as an intermediary component that simplifies the installation process. Instead of directly mounting camera and sensors to the liftgate structure (which would require multiple separate operations), the bracket acts as a mediator that provides a pre-prepared mounting platform, reducing installation complexity while preserving OEM functionality.
3Ease of operation
If camera is made adjustable on liftgate, then rearview visibility is enhanced, but device complexity increases
Solution Approach 1:
The camera mount incorporates an adjustable mechanism that allows the camera to be positioned at different angles and orientations. This dynamic capability enables the camera to be optimized for various rearview visibility requirements while maintaining a relatively simple mechanical adjustment system rather than a complex automated one.

AI summary
A disclosed system includes a liftgate housing; a tab of the liftgate housing moveable to an acute angle relative to a first portion of the liftgate housing; a tab aperture disposed in the tab; a first wall and a second wall attached to the liftgate housing, where the first wall, the second wall, and the tab form a barrier to prevent debris from entering into the housing; a camera, where at least a portion of the camera is disposed through the tab aperture, and where movement of the tab relative to the first portion of the liftgate housing adjusts the field of view of the camera.
