Firearm Rotary Drum with Dual Cartridge Chambers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm designs with multiple cartridge chambers are limited to chambers of the same caliber and geometry, restricting the ability to fire different types of ammunition from the same weapon.
Innovation Solution
Integration of differently designed cartridge chambers, such as rotary or sliding drums, allowing for the use of various ammunition types of the same caliber, with adjustable positions relative to the gun barrel and separate ignition systems to prevent accidental firing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple cartridge chambers are designed for the same caliber and geometry, then the firearm structure is simple and easy to manufacture, but the ability to fire different types of ammunition is restricted
Solution Approach 1:
The firearm is divided into multiple cartridge chambers (first and second chambers) with different geometries, allowing each chamber to be optimized for specific ammunition types. This segmentation enables the weapon to handle diverse ammunition without requiring a completely different firearm design for each type.
Solution Approach 2:
The firearm is designed with multi-functional cartridge chambers that can accommodate different ammunition types (e.g., armor-piercing, high-explosive, incendiary) within the same weapon system. The chambers are geometrically configured to universally accept various cartridge configurations while maintaining proper firing functionality.
2Temperature
If cartridge chambers are positioned behind the barrel, then overheating is prevented through air cooling, but the weapon housing becomes larger and more complex
Solution Approach 1:
The cartridge chambers are positioned in a rearward arrangement behind the barrel, utilizing the longitudinal dimension of the weapon housing. This spatial configuration allows hot chambers to be exposed to ambient air for passive cooling without significantly increasing the overall weapon footprint, as the chambers are integrated into the existing housing structure rather than adding lateral bulk.
3Reliability
If only one cartridge chamber is loaded with ammunition, then accidental firing is prevented, but the rate of fire is reduced
Solution Approach 1:
The firearm is pre-configured with multiple cartridge chambers where only one is loaded with ammunition at a time, while others remain empty or contain dummy cartridges. This preliminary arrangement allows the operator to quickly swap between pre-prepared chambers, maintaining a high rate of fire without the risk of simultaneous firing from multiple chambers. The ignition system is designed to activate only the loaded chamber, ensuring safety.

AI summary
The firearm has a barrel (1) and two chambers (2, 3) functionally cooperating with the barrel. The chambers are adjusted with respect to the barrel, where the two chambers have different inner geometry for respectively receiving a telescopic munition (4) and a munition (5) with a case. The two chambers are integrated in a positioning drum or rotary drum, where an empty chamber is integrated between the two chambers.
