Motor Vehicle Door Opening Device for Overheating Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling motor vehicle doors during parking do not effectively address the risk of overheating for living beings inside, particularly children or pets, as they often require external handles and lack detailed mechanisms for opening locked doors.
Innovation Solution
Integration of an opening device into the motor vehicle lock, actuated by a control unit using existing sensors to detect temperature and occupancy, allowing for automatic unlocking and partial or full opening of the door for ventilation, which can be electrically driven to prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an opening device is integrated into the motor vehicle lock to automatically open the door for ventilation, then the protection against overheating is improved, but the device complexity increases
Solution Approach 1:
The opening device is integrated into the motor vehicle lock mechanism, combining the locking and opening functions into a single system. This reduces the need for separate external handles and complex door opening mechanisms, while enabling automatic door opening for ventilation when overheating is detected.
Solution Approach 2:
The motor vehicle lock is designed to perform multiple functions: securing the door closed during normal operation, and automatically opening the door when ventilation is needed. This multi-functional design eliminates the need for separate dedicated opening devices, reducing overall system complexity while improving safety.
2Temperature
If the motor vehicle door is opened fully manually through a gap, then the ventilation effectiveness is improved, but the aerodynamic design is worsened
Solution Approach 1:
The door opening system provides dynamic control, allowing the door to be opened to different positions (partially or fully) depending on the ventilation needs. The gap position can be adjusted to balance ventilation effectiveness with aerodynamic considerations, rather than being fixed in one position.
Solution Approach 2:
The system changes the door position parameter dynamically - opening it just enough to create sufficient gap for ventilation while minimizing the impact on aerodynamics. The opening distance can be controlled to optimize the balance between cooling effectiveness and aerodynamic performance.
3Shape
If external door handles are removed for aerodynamic design, then the aerodynamic performance is improved, but the ease of operation is worsened
Solution Approach 1:
The motor vehicle lock system automatically performs the door opening function without requiring manual intervention from occupants. When overheating is detected, the system self-activates to open the door, eliminating the need for external handles that would require manual operation while maintaining aerodynamic design.

Implementation Method 1
The motor vehicle lock is configured as an electric lock with an electric motor drive which can be used to open a locking mechanism
Implementation Method 2
the opening device is actuated by the control unit and opens the motor vehicle door, forming a gap at least wide enough to allow the interior of the motor vehicle to be ventilated through the door seal
Implementation Method 3
a second sensor is provided, which is used to detect an increase in temperature inside the vehicle

AI summary
A method for controlling movements of at least one motor vehicle door of a parked motor vehicle. First, the presence of at least one living being inside the motor vehicle is determined using at least one sensor. Then, an increase in temperature inside the motor vehicle is detected using a further second sensor. A control unit evaluates the above-mentioned sensor signals so that an actuator opens the motor vehicle door. According to the invention, an opening device for the motor vehicle door is used as the actuator.
