Solution Overview

Problem

Existing multi-barreled weapons often require a dedicated cartridge chamber, which can lead to increased stress on barrels during high-rate firing and may not be compact enough for efficient ammunition handling.

Innovation Solution

The belt system takes over the function of the cartridge chamber, with flexible belt links designed to align with the barrels and integrate the ammunition, eliminating the need for a separate chamber and allowing for continuous ammunition supply and ignition through a roller closure mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a dedicated cartridge chamber is used in multi-barreled weapons, then the weapon can maintain structural integrity and reliability, but the barrel stress increases during high-rate firing and the device becomes less compact

Engineering Contradiction:
Improvestructural integrityVSAvoidbarrel stress
Core Design Contradiction:
ReliabilityVSStress or pressure

Solution Approach 1:

The patent merges the cartridge chamber function with the belt system by making the belt link itself serve as the chamber. The belt link is designed with a closed bottom and open top, forming a functional chamber that holds the cartridge and propellant charge, eliminating the need for a separate dedicated chamber structure. This integration reduces the overall device complexity and improves compactness while maintaining reliability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The belt link is designed to perform multiple functions simultaneously: it serves as both the ammunition carrier and the cartridge chamber. The belt link's closed bottom acts as the chamber floor, while its open top allows for cartridge insertion and removal. This multi-functional design eliminates the need for separate chamber structures and reduces the number of components required in the weapon system.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If a dedicated cartridge chamber is used, then ammunition can be stored and managed, but the device complexity increases and compactness is reduced

Engineering Contradiction:
Improveammunition handlingVSAvoidchamber structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the ammunition storage function with the belt system. The belt link serves as both the transport element and the cartridge chamber, eliminating the need for separate chamber structures. This integration reduces device complexity while maintaining ammunition handling capabilities, as the belt system continues to facilitate continuous ammunition supply to the barrels.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If traditional chamber systems are used, then reliable cartridge containment is achieved, but the weapon cannot maintain continuous firing without downtime

Engineering Contradiction:
Improvecartridge containmentVSAvoidfiring rate
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent enables continuous firing by integrating the cartridge chamber with the belt system that continuously supplies ammunition to the barrels. As one barrel fires, the belt system immediately provides a new cartridge to the next barrel in the rotation, eliminating downtime between shots. The belt link's closed bottom provides reliable cartridge containment while the continuous belt movement ensures uninterrupted ammunition supply, maintaining high firing rates without sacrificing reliability.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A multiple-barrel weapon (1) is proposed, having a belt system (5) which can not only hold a conventional or other round (6) and may itself be a component of the round (6), but, together therewith, forms a cartridge chamber (22) for the multiple-barrel or multiple-tube weapon (1) as a result of which it is possible to dispense physically with a dedicated complete cartridge chamber. Stars (12, 13) of a roller breech are responsible for transporting the belt element system (5), wherein shells (12.1, 13.1) of the stars (12, 13) partially chamber the belt element (4) in the firing position.
