Solution Overview

Problem

Conventional silencers with concentric bores obstruct the sight plane of firearms, reducing user accuracy and requiring a solution that allows for easy, secure mounting and adjustment of silencers with eccentric bores to maintain clear sight alignment.

Innovation Solution

A rotationally adjustable mounting system comprising a piston with a longitudinal bore and a booster housing with an eccentric bore, allowing the silencer to be oriented out of the sight plane and securely re-aligned without affecting projectile passage alignment, using a mechanism of spokes and notches for rotational adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a conventional silencer with a concentric bore is incorporated with a pistol, then the silencer can reduce sound and muzzle flash, but the silencer obstructs the sight plane of the firearm, reducing user accuracy

Engineering Contradiction:
Improvesound and muzzle flash reductionVSAvoidsight plane clarity and user accuracy
Core Design Contradiction:
Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The patent applies asymmetry by positioning the bore axis of the silencer eccentrically relative to the outer body of the silencer. This asymmetric configuration allows the bulk of the silencer body to lie beneath the bore axis, clearing the sight plane of the firearm while maintaining the bore alignment for accurate projectile passage. The mounting system includes an offset bore in the mounting apparatus that aligns with the eccentric bore in the silencer, enabling this asymmetric arrangement.

Inventive Principle:
Principle #4Asymmetry

2Measurement precision

If a silencer with an eccentric bore is used to clear the sight plane, then user accuracy is maintained, but the mounting and alignment of the silencer becomes more complex

Engineering Contradiction:
Improvesight plane clearance and user accuracyVSAvoidmounting system complexity and alignment requirements
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring the mounting apparatus with an offset bore that is specifically designed to align with the eccentric bore of the silencer. The mounting system includes pre-positioned alignment features and a pre-assembled booster device with the offset bore, so that when the silencer is mounted, the bores are automatically aligned without requiring complex field adjustments. This preliminary preparation simplifies the overall mounting process despite the eccentric configuration.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If the silencer is securely mounted to ensure proper alignment, then projectile passage accuracy is maintained, but the ease of removing and reinstalling the baffle core is reduced

Engineering Contradiction:
Improveprojectile passage alignment accuracyVSAvoidbaffle core removal and reinstallation ease
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent applies segmentation by dividing the silencer into separate components: the silencer body with the eccentric bore, the mounting apparatus with the offset bore, and the removable baffle core. The baffle core can be independently removed and reinstalled through the eccentric bore without requiring disassembly of the entire mounting system. This segmentation allows the baffle core to be easily accessed and replaced while maintaining the secure alignment of the eccentric bores in the silencer and mounting apparatus.

Inventive Principle:
Principle #1Segmentation

AI summary

The disclosure generally relates to a booster for a silencer. The booster includes a piston with a proximal end and a distal end. The proximal end of the piston is configured to couple to a firearm such that a projectile can pass thorough the piston from the proximal end to the distal end. The distal end of the piston includes a flange with a plurality of spokes. The booster further includes a housing with an eccentric bore configured to couple to a silencer. The eccentric bore aligns the silencer below the sight plane of the firearm.
