Solution Overview

Problem

Existing silencers for firearms have inefficient and time-consuming connection methods, often relying on threads, which complicate quick attachment and detachment, and may not provide a secure fit.

Innovation Solution

A silencer design featuring a connecting device with symmetrically arranged bolts and projections that engage via a spring-loaded mechanism, allowing for easy and secure attachment and detachment by screwing onto the firearm barrel, with an elastic ring for enhanced holding force and a detachable expansion module for length adjustment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a thread connection is used to attach the silencer to the firearm barrel, then the connection is simple in structure, but the attachment and detachment process becomes time-consuming

Engineering Contradiction:
Improveconnection structureVSAvoidattachment and detachment time
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The connecting device is divided into separate components: a connecting piece with threaded engagement for the barrel, and an assembly with bolts and engagement elements. This segmentation allows the silencer to be quickly attached by simply screwing the connecting piece onto the barrel, while the bolts and engagement elements provide secure locking without requiring complex threading operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting device incorporates pre-positioned bolts and engagement elements that are ready to lock into place immediately upon attachment. The engagement elements are designed to automatically engage with the bolts when the connecting piece is screwed onto the barrel, eliminating the need for manual locking operations and reducing attachment time.

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If a simple thread connection is used, then the structure is easy to manufacture, but the connection security and firmness are insufficient

Engineering Contradiction:
Improveconnection structureVSAvoidconnection security
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The connecting device merges two connection mechanisms: a threaded connection for initial attachment and a bolt-with-engagement-element mechanism for secure locking. The engagement elements work together with the bolts to create a firm, secure connection that prevents accidental disassembly while maintaining ease of manufacture through modular design.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connecting device uses a composite approach combining different connection methods (threaded engagement and bolt-based positive locking) to achieve both ease of manufacture and high reliability. The spring element adds another layer of security through elastic retention, creating a multi-mechanism connection system.

Inventive Principle:
Principle #40Composite materials

3Reliability

If a secure locking mechanism with multiple bolts and engagement elements is implemented, then the connection firmness is improved, but the device complexity increases

Engineering Contradiction:
Improveconnection firmnessVSAvoidconnecting device structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The connecting device is segmented into distinct functional parts: the connecting piece for barrel attachment, the assembly with bolts, and the engagement elements. This segmentation allows each component to be simple in design while the combination provides secure locking, reducing overall manufacturing complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The engagement elements are designed to automatically engage with the bolts when the connecting piece is screwed onto the barrel. The spring-loaded engagement elements self-actuate to lock the connection without requiring additional manual operations, reducing the complexity of control mechanisms while maintaining high connection firmness.

Inventive Principle:
Principle #25Self-service

4Reliability

If the silencer is firmly secured to prevent accidental disassembly, then the connection reliability is improved, but the ease of detachment for adjustment or removal is reduced

Engineering Contradiction:
Improveanti-accidental-disassemblyVSAvoiddetachment convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The connecting device uses a dynamic spring-loaded engagement element that provides strong holding force during normal operation to prevent accidental disassembly. When detachment is intentionally initiated by unscrewing the connecting piece, the spring force is released and the engagement elements disengage from the bolts, allowing easy removal. This dynamic mechanism provides both security and ease of operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The spring-loaded engagement elements create a preliminary locking action that prevents accidental disassembly under normal conditions. However, this same mechanism is designed to be easily overridden by applying reverse torque to the connecting piece, which releases the spring force and allows intentional detachment. The system anticipates both accidental and intentional operations and responds appropriately.

Inventive Principle:
Principle #9Preliminary anti-action

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

Enables rapid and secure mounting of the silencer, prevents accidental disassembly, reduces gas escape, and maintains a compact firearm length while allowing for adjustable damping performance.

Implementation Method 1

at least one elastic ring is arranged between the assembly and the connecting device, which is compressed at least in the end position of the connecting device in the form-fitting position and thus exerts the spring force in the running direction on the connecting device against the assembly

Methodology Applied
