Firing Pin Release Mechanism for Path-Independent Shot Initiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms mechanisms require the firing pin to be triggered by a fixed trigger or hammer, which limits shot release to specific positions of the returning masses, potentially leading to undefined shot states and longer recoil integration.
Innovation Solution
A firing pin release mechanism actuated by a trigger mechanism on the breech or weapon barrel, where a cocked firing pin is held or released by a crossbar, allowing independent shot initiation from the weapon housing, with a locking pin engaging and disengaging to control the firing pin's position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the firing pin is triggered by a fixed trigger or hammer, then the mechanism is simple and reliable, but the shot release is limited to specific positions of the returning masses, potentially leading to undefined shot states and longer recoil integration
Solution Approach 1:
The firing pin mechanism is segmented into independent components: the firing pin itself, the crossbar for holding/cocking, and the locking pin for engagement/disengagement. This segmentation allows the firing pin to be cocked and held in a consistent position independently of the breech's position relative to the weapon housing, enabling path-independent shot release.
Solution Approach 2:
The crossbar acts as an intermediary element between the locking pin and the firing pin. It provides a surface for the locking pin to engage with, allowing the firing pin to be cocked and held in a consistent position regardless of the breech's position. This intermediary mechanism enables the firing pin to be triggered independently of the weapon housing position.
2Reliability
If the firing pin is held in a cocked position by a crossbar with a locking pin, then path-independent shot release is enabled, but the structure becomes more complex
Solution Approach 1:
The crossbar and locking pin mechanism provides dynamic control over the firing pin's position. The locking pin can engage with or disengage from the crossbar, allowing the firing pin to be held in a cocked position or released as needed. This dynamic mechanism ensures the firing pin is in a consistent, reliable position while maintaining the ability to fire independently of the breech position.
3Productivity
If the firing pin is released before recoil completion, then shooting speed is improved, but safety risks may increase due to potential undefined states
Solution Approach 1:
The firing pin is cocked and held in a ready position by the crossbar and locking pin mechanism before the shot is actually fired. This preliminary action ensures that the firing pin is in a consistent, safe position and ready to fire immediately when needed, without requiring the breech to return to a specific position. This eliminates undefined states while maintaining high shooting speed.
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 allows for path-independent shot release, enabling firing before recoil completion and enhancing safety by avoiding undefined states, as the firing pin can be cocked and held in a consistent position regardless of the breech's position relative to the weapon housing.
Implementation Method 1
A spring-loaded firing pin (11) is cocked and held in a consistent position

AI summary
It is proposed that the firing pin (11) which is integrated in the breech (2) be operated by means of a release mechanism (15) which is located adjacent to the breech (2) or the weapon barrel (5), preferably adjacent to a breech ring (6), which can rotate. The firing pin (11), which is cocked by a spring (12), is in this case held in a cocked position or released by means of a lateral bolt (13). A safety pin (14) engages in or acts on the lateral bolt (13) and is forced back from the lateral bolt (13) by the release mechanism (15) at the latest when the breech (2) is functionally connected to the weapon barrel (5) such that the firing pin (11) together with the firing initiator (10) initiates the firing of ammunition (3). Further means (6.2) are used to cock the firing pin again, thus permitting the lateral bolt (13) to reengage in front of the firing pin (11), in order to hold the firing pin (11) in its cocked position.
