Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional pocket pistols are bulky due to their design, which affects accuracy and concealability, and their recoil mechanism can be uncomfortable for users due to the positioning of the recoil line over the hand.

Innovation Solution

A compact firearm design incorporating a vertical firing pin selector that allows for a more ergonomic grip and reduced size, with a hammer mechanism that strikes the firing pin perpendicular to the barrel axis, enabling intuitive aiming and reduced recoil impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If conventional pocket pistol design is used, then the firearm can be concealed, but the size and bulkiness increase due to grip and slide components

Engineering Contradiction:

Improvefirearm sizeVSAvoidconcealability

Core Design Contradiction:

Volume of moving objectVSEase of operation

Solution Approach 1:

The patent repositions the firing pin selector from a conventional horizontal arrangement to a vertical orientation perpendicular to the barrel axis. This dimensional change allows the mechanism to be compacted along the barrel length rather than extending laterally, reducing overall firearm volume while maintaining operational functionality

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The invention inverts the traditional firing pin selector orientation by positioning it vertically rather than horizontally. The selector extends upward perpendicular to the barrels, with the hammer striking from above, reversing the conventional arrangement and enabling a more compact grip area for concealability

Inventive Principle:

Principle #13The other way round (Inversion)

2Measurement precision

If conventional pocket pistol design is used, then the firearm can be held, but accuracy reduces due to reduced barrel length

Engineering Contradiction:

ImproveaccuracyVSAvoidbarrel length

Core Design Contradiction:

Measurement precisionVSLength of moving object

Solution Approach 1:

By orienting the firing pin selector vertically perpendicular to the barrel axis, the patent frees up lateral space that can be utilized to extend the barrel length without increasing the overall width or grip size. This allows for a longer effective barrel length to improve accuracy while maintaining a compact form factor

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Object-affected harmful factors

If grip size is increased to reduce recoil impact, then recoil comfort improves, but the weapon size and bulkiness increase

Engineering Contradiction:

Improverecoil impactVSAvoidweapon size

Core Design Contradiction:

Object-affected harmful factorsVSVolume of moving object

Solution Approach 1:

The inverted vertical firing pin selector arrangement repositions the recoil line away from the user's hand by changing the mechanical geometry. The hammer strikes from above the vertical selector, creating a recoil path that does not pass over the grip, thereby reducing recoil impact on the user's hand without requiring a larger grip size

Inventive Principle:

Principle #13The other way round (Inversion)
