Handgun Lock System Pendulum Inertial Mass Multi-Directional Impact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handgun safety devices are ineffective in preventing unintentional firing when the weapon falls over or experiences impacts in directions other than its longitudinal axis, as they primarily address shot doubling and not broader fall or tipping scenarios.
Innovation Solution
A handgun with a lock system featuring a pivotably arranged intermediate lever and a pendulum weight as inertial mass, allowing the intermediate lever to be moved out of contact with the locking lever in multiple directions via a slot connection, ensuring safety against various impact orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a block-shaped guide part is used as inertial mass to prevent shot doubling, then longitudinal impact safety is improved, but protection against lateral impacts and weapon falls is insufficient
Solution Approach 1:
The patent transitions from a block-shaped inertial mass that only responds to longitudinal impacts to a pendulum weight that can respond to impacts from multiple directions. The pendulum weight is arranged to swing in an arc, allowing it to react to lateral impacts, upward impacts, and weapon falls in addition to longitudinal impacts, thereby providing comprehensive multi-directional protection.
Solution Approach 2:
The patent employs a dynamic pendulum mechanism where the pendulum weight can swing freely in response to impacts from any direction. This dynamic response allows the safety mechanism to adapt to various impact scenarios including lateral impacts, upward impacts, and weapon drops, overcoming the static limitation of the block-shaped guide part.
2Device complexity
If the intermediate lever is rigidly connected to the inertial mass, then the structure is simple, but it cannot effectively interrupt contact during unwanted impacts
Solution Approach 1:
The patent introduces a control surface as an intermediary element between the pendulum weight and the intermediate lever. The control surface with its specific geometry (inclined plane and flat surface) mediates the interaction, allowing the pendulum weight to effectively interrupt the contact between the intermediate lever and locking lever through controlled geometric interaction rather than rigid connection.
3Adaptability or versatility
If a complex switching mechanism with multiple components is used to achieve multi-directional safety, then protection against various impacts is improved, but device complexity increases
Solution Approach 1:
The patent merges the inertial mass function with the pendulum safety mechanism into a single integrated component. The pendulum weight serves both as the inertial element and the safety actuator, eliminating the need for separate switching mechanisms and multiple components while achieving comprehensive multi-directional protection.
Solution Approach 2:
The pendulum weight performs multiple functions: it acts as the inertial mass, the safety actuator, and the interrupter of the firing sequence. This multi-functional design achieves comprehensive protection against all impact directions without requiring additional specialized components for each function.
