Air Gun Shotshell Partition Design for Universal Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air gun shotshells are unsuitable for hunting fast-moving targets like game birds due to poor accuracy and lethality, as they often rely on light shot payloads and break apart upon exiting the muzzle, and are not universally compatible with existing air guns.
Innovation Solution
A universal air gun shotshell design featuring a cylindrical housing with a partition and cap, including gas flow apertures that allow pressurized gas to propel multiple projectiles in a consistent and lethal manner, compatible with various air guns, mimicking traditional shotgun performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If air gun shotshells use light shot payloads to reduce weight, then the cartridges can be fired from more air guns, but the accuracy and lethality deteriorate
Solution Approach 1:
The cartridge is divided into multiple chambers separated by partitions, with each chamber containing shot of different weights. This segmentation allows the cartridge to achieve both low overall weight for compatibility with more air guns and sufficient shot weight in specific chambers for maintaining accuracy and lethality.
2Reliability
If air gun shotshells are designed for specific gun models, then performance can be optimized, but adaptability and ease of operation deteriorate
Solution Approach 1:
The cartridge is designed with universal compatibility features including a standardized rim configuration that fits multiple air gun models. The partitioned chamber design allows the same cartridge to function effectively across different gun types while maintaining optimized performance through selective chamber activation based on gun pressure and velocity characteristics.
3Reliability
If air gun shotshells use heavy shot payloads to improve lethality, then accuracy and stopping power improve, but the cartridges can only be fired from high-power air guns, reducing adaptability
Solution Approach 1:
The cartridge contains multiple chambers with progressively heavier shot weights. Lighter shot chambers can be activated in lower-power air guns to ensure proper cycling and function, while heavier shot chambers become available when fired from high-power air guns that can generate sufficient pressure and velocity, thus achieving adaptability across different gun types while maintaining lethality when conditions permit.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides robust, accurate, and lethal shot patterns, achieving velocities over 1,000 feet per second with consistent results across different air guns, effectively hunting small and large game, including birds, with minimal audible report.
Implementation Method 1
when the cartridge exits the muzzle of an air gun after a volume of pressurized gas provided by the air gun is flowed through the at least one gas flow aperture into the interior space

AI summary
An ammunition cartridge for an air gun includes a housing, a partition, a cap, at least one projectile, and at least one gas flow aperture. The housing defines an interior space. The housing has a rear portion and a forward portion. The partition is disposed in the interior space and engaged with the rear portion. The cap is releasably engaged with the forward portion. The at least one projectile is received in the interior space between the partition and the cap. The at least one gas flow aperture extends through the partition and provides a fluid flow path through which a pressurized gas provided by the air gun enters and pressurizes the interior space to propel the cartridge through a barrel bore of the air gun.
