Solution Overview

Problem

Existing pistol holsters fail to efficiently accommodate firearms with or without tactical lights and silencers without requiring additional parts or modifications, and often lack optimal retention mechanisms.

Innovation Solution

A modular pistol holster with a solid plastic body covering the firearm except for the grip, featuring a movable sight guide and spring elements in its inner cavity, allowing secure retention of firearms with or without silencers and tactical lights, using a combination of spring elements and a hinged retention mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed sight guide structure is used in the holster, then the manufacturing is simpler, but the holster cannot accommodate firearms with different configurations (with or without silencers and tactical lights)

Engineering Contradiction:
Improveaccommodation of different firearm configurationsVSAvoidholster structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The sight guide is made movable within the holster body through spring elements that allow it to adjust its position. This dynamic structure enables the sight guide to adapt to different firearm configurations (with or without silencers and tactical lights) while maintaining a relatively simple overall holster design without requiring multiple interchangeable parts

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If additional parts or modifications are added to accommodate different firearm configurations, then the adaptability improves, but the device complexity and number of parts increases

Engineering Contradiction:
Improveaccommodation of different firearm configurationsVSAvoidnumber of additional parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The holster is designed with a universal sight guide structure that can accommodate multiple firearm configurations (pistol alone, pistol with silencer, pistol with tactical light, or pistol with both silencer and tactical light) using the same basic components. The spring-loaded sight guide automatically adjusts to fit different configurations without requiring additional parts or modifications

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If a simple retention mechanism is used, then the ease of operation improves, but the reliability of firearm retention decreases

Engineering Contradiction:
Improvefirearm retention securityVSAvoidholstering and unholstering operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The retention mechanism uses spring elements that provide automatic dynamic retention - the springs maintain constant pressure on the sight guide to securely hold the firearm in various configurations. When unholstering, the user simply pulls the firearm outward, and the spring-loaded sight guide automatically releases, providing both secure retention and easy operation without complex locking mechanisms

Inventive Principle:
Principle #15Dynamics

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

AI summary

A pistol holster is formed as a rigid hollow body (1) covering the pistol except of its grip. The holster body (1) contains a longitudinal inner cavity (26) in which, under the back of the body (1), a firearm sight guide (2) is movably and flexibly seated by means of spring elements (9) mounted and arrested in holes of the guide (2) and beared by their opposite ends against a plate (3) situated in the cavity (26) above the guide (2). The holster further contains a swivel-mounted sight cover (4) to secure the position of the guide (2) with the plate (3) within the cavity (26).
