Armoured Vehicle Door Anti-Mine Bolt Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle door designs with anti-mine bolts and braking devices are prone to unintentional closure and failure during one-handed operation, leading to potential destruction of the anti-mine protection system.
Innovation Solution
The vehicle door design separates the door opening mechanism from the anti-mine protection and braking device, requiring the anti-mine bolt to be unlocked before the door can be opened, and incorporates a separate handle for the anti-mine bolt operation, ensuring coordinated locking and opening with the anti-mine bar, allowing one-handed operation while preventing unintentional closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single handle is used to operate both the door opening and the braking device, then one-handed operation is achieved, but the risk of unintentional closure and failure of the anti-mine protection increases
Solution Approach 1:
The patent divides the door operation system into two separate handling mechanisms: a first handle (3) exclusively for opening the door, and a second handle (4) exclusively for operating the braking device and anti-mine bolts (5, 6). This segmentation eliminates the risk of unintentional closure while maintaining one-handed operation capability, as each handle performs its specific function independently without interfering with the other system.
2Ease of operation
If the door opening mechanism is coupled with the braking device, then coordinated operation is achieved, but the position of the anti-mine bar cannot be properly taken into account
Solution Approach 1:
The patent introduces the second handle (4) as an intermediary mechanism that mediates between the door opening system and the braking device. The second handle is mechanically connected to both the braking device (9) and the anti-mine bolts (5, 6), ensuring that the anti-mine bar position is properly considered and coordinated with the door locking system. This intermediary mechanism ensures that the door cannot be opened unless the anti-mine protection is properly engaged.
3Ease of operation
If the braking device is allowed to open the door, then door opening support is provided, but unintentional destruction of anti-mine protection may occur
Solution Approach 1:
The patent applies preliminary anti-action by designing the second handle (4) to first engage and secure the anti-mine bolts (5, 6) in their protective position before the door opening mechanism can be activated. The braking device (9) is mechanically linked to the second handle such that it can only assist door opening when the anti-mine protection is already engaged, preventing any scenario where the braking device could cause unintentional destruction of the anti-mine protection.
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
This design ensures safe and reliable operation of the anti-mine bolt and door locking system, preventing unintentional closure and enhancing user safety by ensuring the anti-mine protection is engaged before the door can be opened or closed, thus maintaining protection against mines and other threats.
Implementation Method 1
a braking device (9), in particular a damper system, for supporting the opening of the door (1)
Implementation Method 2
The handle (4) itself has a spring which presses the handle (4) into the normal setting or normal position

AI summary
A vehicle door (1) is proposed for an armoured vehicle having at least one mine protection bolt (5, 6) and at least one door lock (7) which can be locked by means of a handle (3) in order to open the vehicle door (1), and the opening of the vehicle door (1) is at least assisted by a braking apparatus (9), with the braking apparatus (9) being activated by means of a further handle (4), in addition to the unlocking and locking of the mine protection bolt (5, 6).
