Armored Vehicle Door Anti-Mine Bolt and Lock Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle doors for armored vehicles require multiple movements to open and close, and the risk of inadvertently unlocking the anti-mine protection bar when releasing the braking device poses a threat to protection against mines and other hazards.
Innovation Solution
A single handle is used to both unlock the door lock and move the anti-mine protection bolt into the locking position, simplifying the operation and ensuring the anti-mine bar is securely locked, with a braking device that can be released using the same handle to facilitate easy opening and closing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate handle is used to operate the anti-mine bar, then the anti-mine protection can be independently controlled, but the number of operations required to open or close the door increases
Solution Approach 1:
The patent combines the handle for operating the anti-mine bar with the handle for unlocking the door lock into a single integrated handle. This unified handle allows both functions (anti-mine bar control and door lock unlocking) to be performed through one operational interface, reducing the number of separate operations required while maintaining independent control over both safety functions.
Solution Approach 2:
The single handle is designed to perform multiple functions: it can operate the anti-mine bar to extend or retract it, and it can also unlock the door lock. This multi-functional design eliminates the need for separate handles for each function, streamlining the door operation process while ensuring both protection systems remain controllable.
2Adaptability or versatility
If multiple handles are used for different functions, then each function can be controlled independently, but the time required to open or close the door increases
Solution Approach 1:
The patent merges the previously separate handles into one unified handle that controls both the anti-mine bar operation and the door lock unlocking mechanism. This consolidation allows the user to perform both functions through a single continuous or sequential operation on the same handle, significantly reducing the total time required to open or close the door while maintaining the ability to control each function independently through the same interface.
3Ease of operation
If the braking device is released by the handle, then the door can be moved easily, but there is a risk that the anti-mine bar is not properly locked
Solution Approach 1:
The patent integrates the braking device release function into the same single handle that operates the anti-mine bar and door lock. The handle is designed with a specific operational sequence or mechanical interlocking system that ensures the anti-mine bar is properly locked before the braking device can be released, or that both functions are activated together. This prevents the scenario where the brake is released while the anti-mine bar remains unlocked, as both functions are controlled through the same operational interface with built-in safety logic.

AI summary
The door has a mine protective bolt (40a, 40b) that is movable into a locking position using a handle (2). A door lock (42) is unlockable for opening a vehicle door (1) using the handle, where the handle is rotatably supported. The door lock is moved into unlocked position during rotation in a rotation direction, and the protective bolt is moved into the locked position during rotation in another rotation direction. The handle is arranged on an inner side of the door. An external handle is arranged on an outer side of the door, where the door lock is unlockable using the external handle.
