Vehicle Storage Bin Lock Control for Emergency Evacuation Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During emergency situations, passengers often attempt to retrieve personal items from storage bins on vehicles, which can obstruct emergency exits and delay evacuation, highlighting the need for controlled access to these bins.
Innovation Solution
A system with selectively movable locks on storage bins, controlled by control circuitry that determines the vehicle's operational status using sensors and switches, locking bins during critical events and unlocking them during non-critical events or upon override signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If storage bins are kept unlocked for easy access, then passenger convenience is improved, but emergency evacuation safety deteriorates due to potential obstruction of emergency exits
Solution Approach 1:
The storage bin locks transition from a static state to a dynamic state that automatically changes based on vehicle operational conditions. The system monitors parameters such as seatbelt sign status, turbulence detection, and emergency alerts to dynamically lock or unlock storage bins, ensuring they remain accessible during normal operations but secured during emergency situations.
Solution Approach 2:
The locking system operates autonomously by monitoring vehicle conditions through sensors and automatically executing lock/unlock actions without requiring manual intervention from passengers or crew. The control circuitry continuously assesses operational status and self-regulates the locking mechanism based on predefined criteria.
2Reliability
If storage bins are locked during emergency situations, then emergency evacuation safety is improved, but passenger convenience deteriorates due to inability to access personal items
Solution Approach 1:
The system performs preliminary locking actions before emergency situations fully develop. When conditions such as seatbelt sign activation or detected turbulence occur, the locks engage in advance to prevent any possibility of storage bin access during critical evacuation phases, eliminating the need for later intervention.
Solution Approach 2:
The system continuously monitors vehicle operational parameters through sensors and feedback loops. When conditions change from emergency to normal operation, the system receives feedback signals and automatically reverses the locking state, restoring access to storage bins. This closed-loop control ensures locks respond appropriately to real-time condition changes.
3Reliability
If an automated locking system is implemented, then emergency evacuation safety is improved, but device complexity increases due to additional control circuitry and sensors
Solution Approach 1:
The control circuitry for the storage bin locking system is integrated into the existing vehicle's control architecture rather than being a completely separate system. The same sensors and control resources used for other vehicle functions (such as seatbelt monitoring and emergency alert systems) are leveraged to control the locking mechanism, reducing overall system complexity.
Solution Approach 2:
The system uses simple parameter thresholds and state changes from existing sensors to trigger locking actions. Rather than complex algorithms or processing, the control logic relies on straightforward parameter monitoring (e.g., seatbelt sign on/off status, turbulence detection thresholds) that can be directly translated into lock/unlock commands without requiring sophisticated computational capabilities.

AI summary
A control system and method of controlling access to storage bins in a vehicle. The system includes a lock configured to be selectively movable between a locked position to prevent access to an interior of the storage bins and an unlocked position to allow access to the interior of the storage bins. A switch is positioned in a cabin of the vehicle. A control circuit is configured to determine an operational status of the vehicle and selectively position the locks. The control circuit can also receive an override signal from the switch and unlock the locks in certain situations.
