Angled Action Firearm Counteracts Muzzle Rise

Solution Overview

Problem

Semiautomatic pistols experience muzzle rise due to their horizontal and level geometry, which reduces accuracy during repeated firing.

Innovation Solution

An angled action firearm design featuring a receiver with an upward-sloping top surface and a slide with a downward-sloping bottom surface, along with a pivotably coupled barrel, which counteracts muzzle rise by providing additional downward force and improving grip-to-barrel ratio.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a horizontal and level frame and slide geometry is used in semiautomatic pistols, then manufacturing simplicity and ease of operation are improved, but muzzle rise occurs which deteriorates accuracy during repeated firing

Engineering Contradiction:

Improveframe and slide geometryVSAvoidaccuracy during repeated firing

Core Design Contradiction:

Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent applies asymmetry by changing the traditional horizontal and level geometry of the frame and slide to an angled configuration. The frame includes an angled top surface and the slide includes an angled bottom surface that abuts against it, creating an asymmetric relationship between these components. This asymmetric angular arrangement fundamentally alters the recoil dynamics to counteract muzzle rise while maintaining manufacturability through standardized angular surfaces.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent implements parameter changes by modifying the geometric parameters of the frame and slide from horizontal/level to angled configurations. Specifically, the top surface of the frame and the bottom surface of the slide are given specific angular orientations relative to each other, creating a controlled angular relationship that generates counteracting forces during recoil. This parameter modification transforms the recoil management characteristics without compromising manufacturing capability.

Inventive Principle:

Principle #35Parameter changes

2Device complexity

If traditional horizontal frame and slide geometry is used, then device simplicity is maintained, but muzzle rise decreases accuracy

Engineering Contradiction:

Improveframe and slide structureVSAvoidaccuracy during repeated firing

Core Design Contradiction:

Device complexityVSMeasurement precision

Solution Approach 1:

The patent applies asymmetry by changing the traditional horizontal and level geometry of the frame and slide to an angled configuration. The frame includes an angled top surface and the slide includes an angled bottom surface that abuts against it, creating an asymmetric relationship between these components. This asymmetric angular arrangement fundamentally alters the recoil dynamics to counteract muzzle rise while maintaining manufacturability through standardized angular surfaces.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The patent applies inversion by reversing the traditional approach to recoil management. Instead of adding complex mechanisms to counteract muzzle rise, the invention inverts the problem by designing the frame and slide geometry itself to inherently generate counteracting forces. The angled surfaces are configured so that during recoil, the interaction between the angled top surface of the frame and angled bottom surface of the slide produces forces that naturally oppose muzzle rise, eliminating the need for additional complexity.

Inventive Principle:

Principle #13The other way round (Inversion)

3Measurement precision

If a heavier slide is provided through angled geometry, then muzzle rise is counteracted and accuracy is improved, but device weight increases

Engineering Contradiction:

Improveaccuracy during repeated firingVSAvoidslide weight

Core Design Contradiction:

Measurement precisionVSWeight of moving object

Solution Approach 1:

The patent applies the counterweight principle by configuring the angled frame and slide geometry to generate counteracting forces during recoil. The angled top surface of the frame and angled bottom surface of the slide are positioned and oriented such that their interaction during recoil creates forces that oppose muzzle rise. This geometric counterweighting system uses the existing slide mass more effectively, distributing and directing forces to achieve muzzle control without requiring additional weight or mass addition.

Inventive Principle:

Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The patent implements parameter changes by modifying the geometric parameters of the frame and slide from horizontal/level to angled configurations. Specifically, the top surface of the frame and the bottom surface of the slide are given specific angular orientations relative to each other, creating a controlled angular relationship that generates counteracting forces during recoil. This parameter modification transforms the recoil management characteristics without compromising manufacturing capability.

AI summary

Various embodiments for an angled action firearm that counteracts muzzle rise are described. The angled action firearm includes a receiver having a first receiver end and a second receiver end. The receiver has a top surface sloping upwards from the first receiver end to the second receiver end. The angled action firearm further includes a slide moveably coupled to the receiver having a bottom surface opposite that of the top surface of the receiver. The slide has a first slide end and a second slide end, where the angled bottom surface of the slide slopes upward from the first slide end to the second slide end. The angled action of the slide causes downward pressure during recoil counteracting muzzle rise.
