Rolling Vehicle Window Block for Passenger Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle safety measures, such as airbags, fail to prevent passengers from being thrown out of a rolling vehicle due to the lack of a fixed barrier, and five-point seat belts are complex and costly, limiting their widespread use.
Innovation Solution
A vehicle device comprising two rail units, a block unit made of flexible material, and a drive unit with a control system that unfolds a block to block the window when the vehicle is detected to be rolling, using a gas inflator and pulley system to secure passengers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If five-point seat belts are used to retain passengers, then protection against being thrown out is improved, but device complexity and cost increase
Solution Approach 1:
The block unit transitions from a static folded state to a dynamic deployed state when rolling is detected. The drive unit provides mechanical actuation to unfold the block unit along the rail, creating a dynamic barrier that adapts to the accident condition. This dynamic approach replaces the always-present physical constraint of five-point seat belts with a condition-triggered barrier.
Solution Approach 2:
The mechanical five-point seat belt system is replaced with an integrated control system comprising detection units (sensors), control units (microprocessors), and drive units (motors or actuators). This substitution reduces mechanical complexity while achieving the same safety function through electronic control and a simpler physical barrier (the block unit).
2Reliability
If a block unit is deployed to block the window, then protection against being thrown out is improved, but ease of operation decreases due to automatic deployment
Solution Approach 1:
The system performs self-diagnosis and self-action through the detection unit that automatically identifies rolling conditions and triggers the control unit to deploy the block unit. This self-service mechanism eliminates the need for passenger intervention during the critical moment of an accident, ensuring protection is activated automatically when needed.
Solution Approach 2:
The detection unit continuously monitors vehicle motion and provides feedback to the control unit. When the feedback indicates rolling motion exceeding predetermined thresholds, the control unit activates the drive unit to deploy the block unit. This feedback loop ensures the system responds appropriately to actual accident conditions while maintaining ease of operation through automatic activation.

Function Achieved in This Case
Effectively prevents passengers from being thrown out of a rolling vehicle by instantly blocking the window with a flexible block unit, enhancing vehicle safety without the complexity and cost of five-point seat belts.
Implementation Method 1
the inflator instantly generates a large amount of gas to the airbags so that the airbags are inflated instantly
Implementation Method 2
The drive unit is connected with the block unit for driving the block unit to the unfolded state from the folded state

AI summary
A vehicle device for protecting passengers from being thrown out is disposed at an inner side of a window of a vehicle. The vehicle device includes two rail units disposed at two opposing sides of the window and a block unit disposed between the rail units. The block unit is connected with a drive unit. The drive unit is connected with a control unit. When the control unit detects that the vehicle is about to roll, the control unit will actuate the drive unit to drive the block unit so that the block unit is rapidly unfolded to block the entire window. Thereby, when the vehicle is rolling, the vehicle device can effectively protect the passengers from being thrown out of the vehicle, improving the safety of the vehicle greatly.
