Vehicle Storage Compartment Ventilation for Trapped Occupants
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency devices for vehicle storage compartments, particularly those on the front side, pose safety risks when a person is locked inside, as immediate opening of the closure element during vehicle travel can be dangerous for the person and other road users.
Innovation Solution
An emergency device with an electronic control unit that generates an emergency signal and triggers a ventilation measure to introduce additional air into the storage compartment, allowing for controlled airflow without immediate full opening of the closure element, which is dependent on the vehicle's travel speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the closure element is immediately opened when a person is locked in the storage compartment, then the person can be freed quickly, but it creates safety risks for the person and other road users during vehicle travel
Solution Approach 1:
The closure element is divided into multiple opening stages: a first opening stage that creates a gap for air intake while maintaining safety, and a second opening stage that fully opens the closure element. This segmentation allows the system to provide ventilation without immediately creating the safety hazards associated with full opening during vehicle travel.
Solution Approach 2:
The system performs preliminary ventilation by opening the closure element to the first position before complete opening. This preliminary action allows air to enter the storage compartment, improving the person's condition while avoiding the dangerous effects of immediate full opening during vehicle motion.
2Object-affected harmful factors
If the closure element remains fully closed during vehicle travel, then safety risks are minimized, but the physical integrity of the trapped person deteriorates due to lack of air
Solution Approach 1:
The closure element's opening is segmented into a controlled first position that provides ventilation gaps while maintaining overall closure. This allows the system to balance safety during travel with the trapped person's need for air, providing partial opening for ventilation without compromising overall safety.
Solution Approach 2:
The system applies partial opening action by moving the closure element to the first position rather than fully opening it. This partial action provides sufficient air intake to maintain the person's physical integrity while avoiding the excessive action of full opening that would create safety hazards during vehicle travel.
3Reliability
If the closure element is opened partially to allow air intake, then the trapped person's physical integrity is maintained, but the closure element's security is compromised
Solution Approach 1:
The closure element's opening sequence is segmented into distinct positions: a first position that provides controlled ventilation gaps while maintaining security, and a second position for full opening. This segmentation allows the system to temporarily reduce security for ventilation purposes while providing mechanisms to restore full security when conditions permit.
Solution Approach 2:
The closure element is designed with dynamic positioning capability, allowing it to move between different opening positions (first position with gaps, second fully open position) based on real-time conditions such as vehicle speed and trapped person's status. This dynamic behavior allows the system to adapt between security and ventilation needs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Ensures the physical integrity of a person locked in the storage compartment by providing airflow without the need for immediate full opening of the closure element, thereby reducing safety risks for the person and other road users.
Implementation Method 1
a ventilation opening is released in an electronically controlled manner, in order to allow air from outside to flow into the storage compartment
Implementation Method 2
at least one fan may be activatable via the electronic control unit, in order to actively convey additional air into the storage compartment
Data Source
AI summary
It is provided an emergency device for a vehicle, comprising an actuation element for attachment in a storage compartment of the vehicle, which is closable by at least one closure element, and an electronic control unit, wherein the actuation element is provided for signaling an emergency by a person located in the closed storage compartment, and the electronic control unit is configured for generating at least one emergency signal in response to an actuation of the actuation element. The electronic control unit is further configured to trigger a ventilation measure in response to an actuation of the actuation element, via which additional air enters the storage compartment that is still closed by the at least one closure element.
