Customizable Firearm Slidable Barrel Safety Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handguns lack effective safety mechanisms, leading to unintentional discharges and potential harm, and existing firearms do not offer versatile functionality for various applications such as firing different types of projectiles or providing light.
Innovation Solution
A customizable firearm design featuring a slidably received barrel with a sear mechanism that selectively locks in cocked positions, allowing for safe alignment and discharge, and optional integration of a flashlight or launching platform for diverse projectile types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If safety mechanisms are added to handguns, then safety is improved, but device complexity increases
Solution Approach 1:
The patent combines the safety mechanism with the existing trigger and sear components. The safety feature is integrated into the trigger assembly by adding a safety lever that interacts with the sear, rather than being a separate independent system. This merging approach improves safety while minimizing additional complexity.
Solution Approach 2:
The safety mechanism is designed to be self-regulating through the interaction between the safety lever, sear, and trigger components. The system automatically engages or disengages safety based on the position of these components, reducing the need for additional control mechanisms or user intervention beyond normal operation.
2Productivity
If firearms are designed for specific purposes (hunting, combat), then functionality is optimized, but adaptability decreases
Solution Approach 1:
The patent employs modular barrel assemblies that can be interchangeably attached to the firearm platform. Different barrel types (rifled for hunting, smoothbore for combat, shorter barrels for concealed carry) can be used with the same basic firearm structure, allowing one platform to serve multiple purposes while maintaining optimized performance for each specific function.
Solution Approach 2:
The firearm is divided into modular segments including interchangeable barrel assemblies, magazine systems, and accessory interfaces. This segmentation allows users to configure the firearm for different applications by swapping components rather than requiring completely different firearm designs.
3Measurement precision
If barrels are made longer to increase accuracy and velocity, then shooting performance is improved, but ease of concealment deteriorates
Solution Approach 1:
The firearm system allows dynamic adjustment of barrel length through interchangeable barrel assemblies. Users can select longer barrels when accuracy and velocity are priorities (such as during hunting or target practice) and switch to shorter barrels when concealment and portability are needed (such as for self-defense or concealed carry situations).

AI summary
A customizable firearm is disclosed. The firearm can perform one or more functions, including firing a bullet, firing a less-than-lethal projectile, and/or providing light. In some cases, the firearm includes a main frame component having an inner cavity, wherein a barrel is slidably received within the cavity so as to selectively slide back and forth within the cavity. In some cases, a proximal end of the barrel comprises a bullet chamber. In such cases, the barrel fires the bullet by carrying the bullet proximally and striking it against a stationary firing pin. In other cases, a firing pin is attached to a distal end of the barrel. In such cases, the barrel discharges the firearm by moving the firing pin distally and striking a cartridge at a distal end of the main frame. In some cases, the barrel rotates between a safe and a fire alignment. Other implementations are described.
