Compact Suppressed Pistol With Nested Baffle and Blowback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sound suppressors for pistols extend the length of the firearm, altering its handling and balance characteristics and making it difficult to holster, particularly for military units, necessitating a more compact yet effective suppressor design.
Innovation Solution
The design incorporates a compact sound suppressor with a container having multiple baffle chambers and truncated cones aligned with the firing axis, along with a blowback system that includes cams and springs to manage the breech and slide motion, allowing for efficient sound suppression while maintaining a compact pistol form.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional sound suppressor is mounted on a pistol, then sound suppression is achieved, but the length of the pistol increases and handling characteristics are altered
Solution Approach 1:
The suppressor is nested within the pistol structure by integrating it with the barrel and slide assembly. The suppressor enters through the barrel opening and is positioned within the slide cavity, allowing the pistol to be holstered in standard containers without external protrusions that would alter handling characteristics.
Solution Approach 2:
The suppressor is positioned in a different spatial dimension relative to the pistol body by utilizing the barrel and slide internal volume. Instead of extending externally along the firing axis, the suppressor is accommodated within the existing structural envelope of the pistol, effectively using internal space to house the sound suppression function.
2Object-affected harmful factors
If a conventional sound suppressor is mounted on a pistol, then sound suppression is achieved, but it becomes difficult to holster the pistol
Solution Approach 1:
The suppressor is nested within the pistol structure by integrating it with the barrel and slide assembly. The suppressor enters through the barrel opening and is positioned within the slide cavity, allowing the pistol to be holstered in standard containers without external protrusions that would alter handling characteristics.
3Ease of operation
If a compact suppressor design is used, then handling and holstering are improved, but sound suppression effectiveness may be reduced
Solution Approach 1:
The suppressor is divided into multiple baffle chambers arranged in series along the firing axis. Each chamber contains baffles that redirect and dissipate exhaust gases sequentially. This segmented approach allows effective sound suppression within a compact length by using multiple stages of gas redirection rather than requiring a single long suppressor section.
Solution Approach 2:
The suppressor incorporates curved exhaust paths and angled baffles that guide exhaust gases through rounded transitions rather than sharp angles. This curvature reduces turbulence and allows for more efficient gas redirection within a compact space, maintaining sound suppression effectiveness while minimizing the overall suppressor length.

AI summary
A suppressed pistol has a breech block and a slide mounted on a frame. The breech block and slide are separate pieces, movable relatively to one another and the frame. A link extends between the breech block and the frame. The link carries a cam and a cam follower. The cam follower on the link engages a cam on the frame, the cam on the link engages a cam follower on the slide. Action between the cams, cam followers and the link causes separation between the breech block and the slide during operation of the pistol. The suppressor includes a container having baffle plates with truncated cones defining openings offset from the geometric centers of the baffle plates.
