Solution Overview

Problem

Recoil from firearms, particularly large caliber handguns and rifles, negatively impacts aim for subsequent shots due to significant backward motion, rotating the weapon and disrupting shooter alignment.

Innovation Solution

A recoil grip with a mounting portion and offset support portion, featuring a lateral grip pad and contoured surfaces to provide a thumb contact point, reducing recoil by allowing the non-trigger hand to counteract the motion and maintain control over the weapon's orientation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a handgun with large caliber is used, then firepower is improved, but recoil impact on aim is worsened

Engineering Contradiction:
ImprovefirepowerVSAvoidaim control
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The patent applies counterweight principle by adding a mass (such as a weight block or dense material) to the handgun grip area to balance the rearward recoil force. This counterweight is positioned to create a counterbalancing moment that opposes the rotational torque generated during recoil, thereby reducing the upward rotation of the handgun and improving aim control for subsequent shots.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The patent introduces a new dimensional element by adding a three-dimensional mass distribution to the handgun grip area. Instead of modifying the barrel or firing mechanism, the solution adds depth and volume to the grip region through attached weights or ergonomically designed grip extensions, creating a counterbalancing moment in the vertical dimension to offset recoil rotation.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Force

If rifle caliber is increased, then firepower is improved, but rotational impact on aim is worsened

Engineering Contradiction:
ImprovefirepowerVSAvoidweapon orientation
Core Design Contradiction:
ForceVSStability of the object's composition

Solution Approach 1:

The patent applies counterweight principle by positioning masses along the rifle stock or grip area to create counterbalancing moments that oppose the rotational torque generated during recoil. These counterweights are strategically placed to shift the center of gravity and reduce the rotational impact on weapon orientation, thereby improving stability for subsequent shots.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The patent applies local quality principle by concentrating mass specifically in the grip and stock regions of the rifle rather than uniformly distributing weight throughout the entire weapon. This localized addition of mass (through attached weights, dense grip materials, or reinforced stock sections) creates targeted counterbalancing effects at the critical rearward contact points, effectively reducing rotational impact without significantly increasing overall weapon weight.

Inventive Principle:
Principle #3Local quality

3Length of moving object

If smaller stock is used in urban assault settings, then maneuverability is improved, but recoil control is worsened

Engineering Contradiction:
Improvestock lengthVSAvoidrecoil control
Core Design Contradiction:
Length of moving objectVSEase of operation

Solution Approach 1:

The patent applies counterweight principle by adding compact masses to the grip area or handguard region of the rifle. These counterweights compensate for the reduced stock length by creating counterbalancing moments at the rearward contact points, thereby maintaining recoil control despite the shorter overall weapon length required for urban maneuverability.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The patent applies preliminary action principle by pre-positioning counterweights or designing ergonomic grip extensions that are already in place before firing. This preliminary configuration of mass distribution ensures that the counterbalancing effect is immediately available when recoil occurs, without requiring any additional action or adjustment during the shooting process.

Inventive Principle:
Principle #10Preliminary action

AI summary

An offhand recoil grip is described. In one disclosed embodiment, a recoil grip has a mounting portion to connect to a grip mount of a handgun, the mounting portion further having an offset support portion extending from the mounting portion toward the top and front of the handgun, the offset support portion having a second planar surface offset from the first planar surface of the mounting portion to allow a slide to move between the recoil grip and a receiver of the handgun, and a lateral grip pad coupled to the offset support portion, the lateral grip pad extending laterally away from the grip mount of the handgun to provide a thumb contact point for a non-trigger hand to reduce recoil in a handgun when fired. Other embodiments are described involving a method of using a recoil grip, recoil grips with different attachments, for different weapons, etc.
