Dummy Ammo Weight Distribution via Counterweight Cavity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing training ammos have a different feel from live ammos due to uneven weight distribution, leading to a poor user experience and difficulty in smooth ejection during training.
Innovation Solution
A dummy ammo design incorporating a counterweight component and a contour component, where the counterweight component is fixed within a cavity of the contour component to simulate the weight distribution of live ammo, thereby improving the user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the first part is made of plastic material and the second part is made of metal material, then the structure is simple and connection is firm, but the center of gravity becomes backward and the feel differs from live ammo
Solution Approach 1:
The patent applies local quality by using different material densities in specific regions of the dummy ammo. The front portion uses denser material while the rear uses lighter material, creating a localized weight distribution that replicates the center of gravity position of live ammunition. This resolves the contradiction by maintaining structural simplicity while achieving realistic shooting feel through targeted material placement.
Solution Approach 2:
The patent changes the physical parameters of the dummy ammo by adjusting material density distribution along the length of the cartridge. By varying the density parameter from front to rear, the design achieves proper weight distribution and center of gravity positioning, thereby improving shooting feel without increasing overall structural complexity.
2Device complexity
If the center of gravity is backward, then the structure is simple, but the ejection becomes difficult during training
Solution Approach 1:
The patent resolves this contradiction by implementing local quality through strategic material placement. Denser material is concentrated in the front portion of the dummy ammo, positioning the center of gravity forward to match live ammunition behavior. This localized density adjustment improves ejection smoothness while maintaining overall structural simplicity.

AI summary
A dummy ammo comprises a counterweight component and a contour component, wherein the counterweight component comprises at least one counterweight block, and the contour component comprises at least one cartridge shell; the cartridge shell is provided with at least one inner wall, and the inner wall defines at least one cavity; the counterweight block is arranged in the cavity; when the counterweight block is fixed, the dummy ammo has a weight distribution close to that of a live ammo, so that the problem of being difficult to eject during training can be solved, and the experience is better when being used.
