Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sliding door drives for motor vehicles face challenges in providing sufficient force transmission while ensuring easy installation, particularly in large doors where the deflection device must be widely spaced, complicating the routing between the vehicle's outer and inner panels.
Innovation Solution
A modular sliding door drive system featuring an electric drive unit, a drive cable, and a cable guide firmly accommodated in the vehicle body, with a modular cable deflection assembly that allows separate installation and adaptation to different door sizes, using a planetary gear for efficient force transmission and a sealing mechanism to secure the drive cable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the deflection device is widely spaced from the drive unit to accommodate large door sizes, then the sliding door can be operated, but the routing between the vehicle outer and inner panel becomes complicated and installation effort increases
Solution Approach 1:
The cable guide is divided into multiple segments or sections, allowing it to be routed through the vehicle body panels in a modular fashion. This segmentation enables the cable to be guided from the drive unit to the deflection device without creating a single complex routing path, as each segment can be independently installed and adjusted to fit different door configurations.
2Force
If the drive cable is firmly connected to the body to enable force transmission, then the sliding door can be moved, but the installation and adaptation to different door sizes becomes difficult
Solution Approach 1:
The cable guide system incorporates adjustable and movable components that allow the routing path and connection points to be dynamically adapted to different door sizes and configurations. This dynamic design enables the same cable guide system to maintain firm force transmission while being adaptable to various door dimensions by adjusting the position and orientation of the cable guide segments.
