Sliding Door Restraint Slot for Lateral Impact Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing restraint devices for sliding rear doors in vehicles are complex due to non-linear kinematics of door displacement, making their positioning challenging, especially when the displacement is inclined, and they fail to effectively prevent the door from opening during lateral impacts.
Innovation Solution
A restraint device is attached to the vehicle's front and middle pillars, featuring a protruding rod with a hook or disk end that moves freely within a longitudinal opening in the door, allowing simple rectilinear movement and effective door retention during impacts, while being discreet and contributing to the locking mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a restraint device is positioned according to normal kinematics of door displacement, then the door can be held in closed position, but the positioning becomes complex when displacement is inclined
Solution Approach 1:
Instead of positioning the restraint device according to the complex inclined kinematics of door displacement, the invention inverts the approach by using a rectilinear opening that simplifies the restraint device positioning to a straightforward longitudinal alignment, eliminating the complexity of inclined positioning while maintaining door retention reliability
2Ease of operation
If the restraint device is spaced apart from the door, then the door can move freely between open and closed positions, but the restraint device must still effectively prevent door opening during impact
Solution Approach 1:
The invention introduces a rectilinear opening as an intermediary element between the restraint device and the door. This opening allows the restraint device to move freely during normal door operation while providing a controlled interface for impact restraint, effectively mediating between the need for door movement freedom and impact resistance
