Remote Ammunition Ignition Lever Locking Against Accidental Firing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote-controlled ammunition ignition devices face issues with accidental discharge due to pre-tensioned firing pins, which can be triggered unintentionally by vibrations or shocks, leading to insufficient safety.
Innovation Solution
A device with a movable guide element, a lever, and a safety mechanism that prevents the lever from moving until remotely activated, using an actuator and a return element to ensure controlled ignition, combined with a safety device to impede the movement of the firing pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a pre-tensioned hammer is used for remote-controlled ignition, then the ignition energy is readily available, but the device becomes vulnerable to unintentional ignition due to vibrations and shocks during transport
Solution Approach 1:
The device is divided into functionally independent modules: a hammer module that can be pre-tensioned, a separate trigger mechanism, and a safety system with blocking elements. This segmentation allows the hammer to be prepared for ignition while physically isolated by safety blocks that prevent accidental discharge, thus maintaining both ignition readiness and safety.
Solution Approach 2:
The hammer is pre-tensioned in advance using a tensioning device that can be operated remotely or manually, storing the necessary ignition energy without immediately threatening the safety of the system. The pre-tensioning action is separated from the firing action by intermediate safety mechanisms, allowing energy preparation without compromising safety.
2Speed
If the hammer is pre-tensioned for quick ignition response, then the ignition speed is improved, but the risk of accidental firing increases under vibrational stress
Solution Approach 1:
Safety blocking elements act as intermediaries between the pre-tensioned hammer and the ignition target. These blocks physically intervene to prevent the hammer from striking the ignition element unless deliberately removed or repositioned by the trigger mechanism, thus allowing fast ignition response while blocking harmful vibrational effects.
Solution Approach 2:
The safety system incorporates blocking elements and positioning mechanisms that are in place before the ignition sequence is initiated. These protective measures cushion against the harmful effects of vibrations and shocks by preventing the hammer from moving toward the ignition element under abnormal conditions, while allowing rapid controlled ignition when triggered.
3Reliability
If a complex safety system with multiple independent mechanisms is implemented, then the safety against accidental ignition is improved, but the device complexity increases
Solution Approach 1:
Multiple safety functions are merged into integrated components. For example, the trigger mechanism simultaneously performs the function of releasing the hammer and disengaging safety blocks, while the blocking elements serve both as safety barriers and as part of the firing sequence control. This merging reduces the number of separate mechanisms while maintaining comprehensive safety.
Solution Approach 2:
Key components are designed to perform multiple functions. The trigger mechanism not only initiates firing but also coordinates the disengagement of safety blocks. The blocking elements serve both as safety barriers and as mechanical interfaces for the trigger system. This multi-functionality reduces overall device complexity while maintaining high safety standards.

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, upon movement, 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 remotely controlled driving force. A safety device (14, 18) is also provided, which can restrict the movement of the lever (4).
