Liftgate Camera Housing With Adjustable Rearview Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of a liftgate in vehicles often requires the removal of tailgates and bumpers, which necessitates the relocation of original equipment manufacturer (OEM) backup cameras and proximity sensors, disrupting rearview visibility without a straightforward solution to maintain their functionality.
Innovation Solution
The design incorporates a liftgate housing with adjustable camera mounts and proximity sensor apertures, allowing for the secure mounting of OEM devices, enabling adjustment of camera angles and maintaining rearview visibility without additional modifications or devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a liftgate is installed in a vehicle, then the vehicle gains enhanced loading capability, but the original backup camera and proximity sensors must be removed from the tailgate and bumper, disrupting rearview visibility
Solution Approach 1:
The patent introduces a liftgate housing as an intermediary structure that receives and integrates the backup camera and proximity sensors. The housing includes specifically designed mounting features (camera mount with adjustment mechanisms, proximity sensor mounts with apertures) that accommodate these components, allowing them to function in the new location while maintaining rearview visibility.
Solution Approach 2:
The camera mount includes adjustment mechanisms that allow the camera angle to be dynamically adjusted. The tab of the housing can be moved to an acute angle, and the camera can be positioned at different angles relative to the housing, enabling optimization of the camera's field of view after installation.
2Reliability
If the backup camera and proximity sensors are relocated to the liftgate, then rearview visibility can be maintained, but additional mounting structures and modifications are required
Solution Approach 1:
The patent combines multiple functions into the liftgate housing structure. The housing simultaneously serves as the liftgate mechanism housing, the camera mounting structure, and the proximity sensor mounting structure. Features like the tab aperture, camera mount, and sensor mounts are integrated into the housing itself, reducing the need for separate additional components.
Solution Approach 2:
The liftgate housing is designed as a universal mounting platform that can accommodate both the backup camera and proximity sensors. The housing includes standardized mounting features that can receive different camera and sensor configurations, making it a multi-functional integration point for various rearview visibility components.
3Measurement precision
If the camera angle is adjusted to optimize field of view, then rearview visibility is improved, but the mounting structure must allow for angular adjustment
Solution Approach 1:
The camera mount is designed with dynamic adjustment capabilities. The tab of the housing can be moved to an acute angle, and the camera can be positioned at different angles relative to the housing. This allows the camera angle to be adjusted to optimize the field of view for different installation scenarios and vehicle configurations.
Solution Approach 2:
The mounting structure is segmented into adjustable components. The camera is mounted on a separate adjustable mount rather than being fixed directly to the housing. The tab is a separate movable component that can be positioned at different angles, allowing independent adjustment of each element to achieve optimal camera positioning.

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.
