Monolithic Suppressor Structure for Precise Baffle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suppressor manufacturing techniques face challenges such as inaccurate baffle positioning, time-consuming and costly assembly, potential baffle strike, and the creation of unduly heavy and inefficient products due to redundant material and inadequate support in additive layer manufacturing processes like selective metal melting (SMM) and laser metal sintering (LMS).
Innovation Solution
The method involves using selective metal melting techniques to manufacture a suppressor with a housing and internal components formed integrally, where the components are fused directly to the inner surface of the housing, and the angle between the component underside and the housing wall is optimized between 10° and 85° to enhance manufacturing efficiency and product performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional manufacturing techniques (deforming rigid sheet material, machining, welding) are used to construct suppressors, then the suppressor can be assembled with separate components, but the assembly process is time-consuming and costly, and baffle positioning accuracy is poor
Solution Approach 1:
The patent combines multiple components (baffles, housing, support structures) into a single monolithic structure manufactured by selective metal melting. This eliminates the need for separate assembly operations, achieving both high positioning accuracy (since all components are formed in one process) and reduced assembly time (since no assembly is required). The baffle positioning accuracy improves from poor traditional assembly to precise digital fabrication, and assembly time reduces from time-consuming multi-step assembly to zero.
2Productivity
If selective metal melting is used to manufacture suppressors with internal components, then manufacturing efficiency improves and assembly is reduced, but the suppressor becomes unduly heavy due to redundant material
Solution Approach 1:
The patent segments the monolithic structure into functional zones with varying material density. Solid material is placed only where structurally necessary (housing walls, baffle supports), while internal chambers and gas flow paths are left hollow or partially filled. This segmentation maintains manufacturing efficiency of selective metal melting while eliminating redundant material, thus reducing suppressor weight without sacrificing the productivity benefits of additive manufacturing.
3Device complexity
If selective metal melting is used to manufacture suppressors, then the suppressor can be formed as a single piece, but support structures are inadequate during the manufacturing process
Solution Approach 1:
The patent incorporates temporary support structures and anchoring features directly into the digital model before manufacturing. These preliminary support elements are strategically positioned to provide adequate support during the selective metal melting process, preventing deformation or collapse of internal chambers. After manufacturing, these temporary supports are removed or integrated into the final structure. This preliminary action ensures manufacturing reliability while maintaining the benefit of single-piece construction.
4Ease of manufacture
If traditional manufacturing techniques are used, then components can be assembled separately, but inaccurate baffle positioning and potential baffle strike occur
Solution Approach 1:
The patent merges all components into a single monolithic structure where baffles, housing, and supports are formed as one integrated piece. This eliminates the assembly step (maintaining ease of manufacture through single-step production) while achieving precise baffle positioning (eliminating positioning errors and baffle strike risks). The digital fabrication process ensures exact geometric accuracy that cannot be achieved through traditional assembly of separate components.

AI summary
A suppressor having a body and a first connector half coupled to the body, wherein the first connector half includes a first component that includes at least one channel and a first surface; and wherein the body provides a second surface, wherein a gap between the first surface and the second surface defines at least one track; wherein the gun includes a second connector half comprising at least one protrusion, wherein the protrusion and channel have corresponding shapes that allow the protrusion to be inserted through the channel and into alignment with the track, wherein the first component may be rotated with respect to the protrusion and the body to bring the protrusion out of alignment with the channel so that the first and second surfaces clamp the protrusion to thereby secure the first connector half and second connector half with respect to each other.
