Powered Hinge Assembly with Automatic Installation Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powered tailgate systems for motor vehicles lack efficient and automated mechanisms for proper orientation during installation, leading to potential misalignment and difficulty in reinstallation.
Innovation Solution
A powered hinge assembly with a drive unit, controller, and absolute position sensor that automatically orients the tailgate hinge feature to an installation position upon power connection, allowing manual or automated operation and ensuring correct alignment for easy installation and reinstallation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a powered hinge assembly is installed on a motor vehicle, then automated raising and lowering of the tailgate is achieved, but misalignment and difficulty in reinstallation may occur due to lack of automated orientation
Solution Approach 1:
The controller automatically orients the drive cup to the installation position upon power connection, performing the orientation action in advance before the installation process begins. This preliminary action ensures that the hinge assembly is properly aligned when the installer needs to connect the hinge pin, eliminating manual orientation efforts and preventing misalignment issues during installation and reinstallation
2Adaptability or versatility
If manual operation of the tailgate is allowed, then flexibility is improved, but the risk of misalignment during installation increases
Solution Approach 1:
The powered hinge assembly performs self-alignment automatically upon power connection, with the controller detecting the power connection and autonomously orienting the drive cup to the installation position. This self-service capability ensures precise alignment without requiring manual intervention, thereby maintaining both operational versatility and alignment precision
