Firearm Block Element Trigger Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing semiautomatic pistols lack a selective locking mechanism that prevents the slide and barrel assembly from recoiling automatically when the trigger is pulled, necessitating manual unlocking and failing to suppress action noise when used with sound reduction devices.
Innovation Solution
A locking action firearm design featuring a block element that moves between a rest and blocking position in response to the trigger lever, locking the slide and barrel assembly when the trigger is pulled and unlocking it when released, allowing for conditional locking and manual cycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a locking mechanism is added to prevent semi-automatic function, then control over firing mode is improved, but device complexity increases
Solution Approach 1:
The locking mechanism is merged with the existing trigger lever and block element structure. The block element is integrated into the slide assembly, and its movement is directly coupled with trigger lever actuation, combining the locking function with existing components rather than adding a completely separate mechanism.
Solution Approach 2:
The locking mechanism is designed to be dynamic rather than static. The block element automatically transitions between locked and unlocked positions based on trigger lever movement, allowing the system to adapt its state (locked/unlocked) based on operational conditions without requiring manual intervention or complex control systems.
2Reliability
If the block element is operably connected to the trigger lever to move based on trigger lever position, then locking reliability is improved, but device complexity increases
Solution Approach 1:
The block element is designed to automatically perform the locking and unlocking functions through its operable connection to the trigger lever. When the trigger lever is actuated, the block element self-activates to engage or disengage the locking position without requiring additional actuators, sensors, or control systems, thereby achieving reliable automatic locking with minimal added complexity.
3Object-affected harmful factors
If the slide and barrel are locked when the trigger is pulled, then action noise is reduced, but ease of operation deteriorates due to manual cycling requirement
Solution Approach 1:
The system dynamically adapts its operation mode based on trigger actuation. When the trigger is pulled, the slide and barrel are locked to reduce noise. When the trigger is released, the system automatically unlocks to permit manual cycling. This dynamic behavior allows the system to optimize for noise reduction during firing while maintaining operational capability through automatic unlocking.

AI summary
A locking action firearm has a frame, a barrel connected to the frame, a reciprocating action element operable to reciprocate with respect to the frame between a forward battery position and a rear recoil position, a trigger lever connected to the frame and movable between a forward released position and rear actuated position, and a block element movable between a rest position in which movement of the reciprocating action element from the battery position to the recoil position is enabled, and a blocking position in which the block element contacts the reciprocating action element to prevent movement of the reciprocating action element from the forward battery position to the recoil position in response to movement of the trigger lever to discharge the firearm. The block element may be operably connected to the trigger lever and move based on the trigger lever position.
