Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing handgun silencer attachment methods cause vibration issues, particularly when attached to grips made of plastic, leading to misalignment of the central axis after firing, which prevents subsequent shots in semi-automatic or fully automatic firearms.

Innovation Solution

A fastening device with a support surface that rests on the trigger guard and axial wings to prevent vertical and horizontal swinging, combined with a locking mechanism to secure the silencer, ensuring it remains aligned with the firearm's barrel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the silencer is attached to the mounting rail on the grip, then the silencer can be attached independently of the barrel, but the silencer vibrates independently after firing causing misalignment

Engineering Contradiction:

Improveindependent attachment capabilityVSAvoidalignment stability

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The mounting device is divided into multiple functional components: a mounting rail for attachment to the firearm, a support surface at the rear end that contacts the trigger guard, and axial wings that engage with the trigger guard. This segmentation allows each component to address specific stability issues independently while maintaining overall adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The trigger guard serves as an intermediary structure between the mounting device and the firearm's action system. By engaging the support surface and axial wings with the trigger guard, the mounting device utilizes this intermediate component to prevent vibration and maintain alignment without directly interfering with the barrel or action.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the silencer is mounted on the grip rail, then attachment is simplified, but vertical and horizontal oscillation occurs after firing

Engineering Contradiction:

Improveattachment simplicityVSAvoidfiring reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The mounting device incorporates dynamic engagement features where the axial wings and support surface work together to constrain movement in multiple directions. The design allows for simple initial attachment while dynamically preventing oscillation during the firing cycle through the interaction between the mounting rail and trigger guard.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If the silencer vibrates independently, then the mounting structure is simple, but the central axis becomes misaligned preventing subsequent shots

Engineering Contradiction:

Improvemounting structure complexityVSAvoidrate of fire

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The mounting device addresses alignment issues by adding dimensional constraints through the axial wings that engage with the trigger guard. This multi-dimensional constraint system prevents movement in horizontal and vertical directions simultaneously, maintaining central axis alignment without significantly increasing overall structural complexity.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
