Remote Ammunition Ignition Lever Locking Against Shock Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-controlled ammunition ignition devices face safety issues due to potential unintentional ignition caused by vibrations and shocks, particularly when using pre-tensioned firing pins, which can lead to accidental discharge.
Innovation Solution
A device with a movable guide element and lever system, incorporating a safety mechanism to prevent unintended ignition, utilizing a remotely controlled actuator, a movable lever, and a safety device to impede the movement of the firing pin, combined with a return element to reset the system to a safe state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-tensioned firing pins are used for remote-controlled ignition, then ignition reliability is improved, but safety against unintentional ignition deteriorates
Solution Approach 1:
The device segments the ignition control into three independent functions: pre-tensioning the firing pin, securing the firing pin in a safe position, and triggering the firing pin. This segmentation allows the firing pin to be pre-tensioned for reliable ignition while simultaneously being secured in a safe position to prevent unintentional discharge, resolving the contradiction between ignition reliability and safety.
Solution Approach 2:
The firing pin is pre-tensioned in advance to store the necessary energy for reliable ignition. However, this pre-tensioned state is immediately followed by a securing action that locks the firing pin in a safe position until deliberate triggering occurs. This preliminary action followed by control measures resolves the contradiction by ensuring both ignition readiness and safety.
2Ease of operation
If the striking element is made movable for remote triggering, then remote ignition capability is improved, but vulnerability to vibrations and shocks deteriorates
Solution Approach 1:
The securing device applies a counteracting force to the movable firing pin, holding it firmly in the safe position against any external disturbances such as vibrations or shocks. This preliminary anti-action prevents the firing pin from moving unintentionally while still allowing controlled movement when the triggering device is activated, resolving the contradiction between remote ignition capability and vibration resistance.
3Reliability
If a separate securing mechanism is added to prevent accidental discharge, then safety is improved, but device complexity deteriorates
Solution Approach 1:
The securing device is integrated with the existing firing pin mechanism, using the same structural elements and movement paths. The securing function is combined with the triggering function, where the triggering device simultaneously releases the securing constraint and activates the firing pin. This merging approach improves safety without significantly increasing device complexity.

AI summary
Device for remotely igniting ammunition. The device includes an ignition device (16) and a firing pin (1). Furthermore, the device has a movable lever (4) that can move the firing pin (1). A guide element (2) is movably mounted within the device and, when moved, can cause the lever (4) to rotate. The guide element (2) can assume a rest position from which it can only be moved by an actuator and/or a drive force, which can be remotely controlled. A safety device (14, 18) is also provided, which can restrict the movement of the lever (4).
