Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun lock designs are complex and prone to unintended second-shot discharge due to multiple moving parts, which complicates safety mechanisms.
Innovation Solution
A gun lock design featuring a pendulum mass that swivels between a starting and safe position, disconnecting the trigger and disconnector in opposite directions to prevent second-shot discharge, with detent means reducing stress on sensitive components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple moving parts and coordinated components are used in the gun lock mechanism, then the safety against unintended discharge is improved, but the device complexity increases
Solution Approach 1:
The patent combines the disconnector and trigger bar into a single integrated component that performs both functions: disconnecting the trigger from the hammer and controlling the trigger bar movement. This merging reduces the number of separate moving parts while maintaining the safety functions through the interlocked design of the integrated component.
Solution Approach 2:
The integrated disconnector-trigger bar component performs multiple functions simultaneously: it acts as a disconnector to prevent unintended discharge, serves as a trigger bar to control hammer movement, and provides a locking mechanism through its interlocked design. This multi-functionality reduces overall mechanism complexity while ensuring safety.
2Device complexity
If the detent means are integrated with the moving pendulum mass, then the mechanism is simplified, but the detent means are subjected to greater stress and may fail
Solution Approach 1:
The patent segments the detent means from the pendulum mass, placing the detent means on a stationary component while the pendulum mass remains a separate moving element. This segmentation allows the detent means to engage with the pendulum mass during operation while being anchored to a stable structure, reducing stress on the detent mechanism and improving its durability.

Function Achieved in This Case
Ensures a high degree of safety against unintended second-shot discharge by simplifying the mechanism while minimizing stress on sensitive components, providing a robust safety feature.
Implementation Method 1
the inertial mass is a pendulum mass which swivels about a transverse axis between a starting position and a safe position
Implementation Method 2
the basic body with the intermediate levers pivotably disposed thereon serves as an inertial mass

AI summary
A gun lock of a firearm having two hammers movably disposed on a lock support, a trigger bar for each hammer for holding or releasing the hammers, a trigger, and a disconnector for the trigger, by which disconnector the trigger bars can be moved by the trigger from a holding position into a release position. The disconnector can be moved by an inertial mass between a triggering position, in which the trigger is connected to one of the two trigger bars, and a disconnect position, in which the connection between the trigger and the trigger bars is interrupted. The inertial mass is a pendulum mass swiveling about a transverse axis between a starting position and a safe position, by which the disconnector, upon the release of a first hammer, can be swiveled in a direction opposite to the direction of the pendulum mass into the disconnect position.
