Solution Overview

Problem

Existing passive retention holsters are limited by fixed shapes and configurations, requiring multiple designs for different handgun models and user preferences, leading to increased manufacturing costs and inventory needs, and lack of adjustability for angle and grip position.

Innovation Solution

A versatile, passive retention holster with interchangeable and adjustable accessories, featuring adjustable attachment formations and a contoured cavity for snug handgun fit, allowing for multiple positional arrangements and user preferences.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple holster designs are manufactured for different handgun models and user preferences, then fit and usability are improved, but manufacturing costs and inventory needs increase

Engineering Contradiction:
Improveholster compatibilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The holster body is designed with a universal cavity that can accommodate multiple handgun models through adjustable retention straps and interchangeable accessories, eliminating the need for separate holster designs for different handgun types while maintaining proper fit and retention

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

2Ease of manufacture

If fixed shape and configuration holsters are used, then manufacturing is simplified, but adjustability for angle and grip position is lost

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidposition adjustability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The holster incorporates adjustable retention straps with multiple positioning holes and interchangeable accessories (belt clips, waistband clips, spacers) that allow users to dynamically adjust the holster's angle, position, and orientation while maintaining a fixed, simple holster body design for easy manufacturing

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If passive retention holsters are used, then ease of draw is improved, but security against dislodgement during movement is reduced

Engineering Contradiction:
Improvedraw speedVSAvoidretention security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The holster features pre-configured adjustable retention straps that can be tensioned beforehand to provide secure retention during movement, while still allowing rapid draw when needed. The straps are positioned and tensioned in advance to balance security and accessibility

Inventive Principle:
Principle #10Preliminary action

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

Enables a single holster design to accommodate various handguns and user preferences, reducing manufacturing costs and inventory needs while providing secure, adjustable fit and quick access.

Implementation Method 1

Some holsters rely solely on a friction fit between the holster and the handgun to secure and retain the handgun securely within the holster

Methodology Applied
Scientific EffectFriction: Friction

AI summary

A passive retention holster including a holster body and at least one compatible holster accessory, wherein the holster body includes a cavity, configured to realisably receive and retain a preselected handgun frictionally therein. The holster body is provided with a first adjustable attachment formation, located on one side of the holster body, wherein the first attachment formation is dimensioned and configured to render the body operatively securable, adjustably, to the compatible holster accessory; and a second adjustable attachment formation, located on an opposing side of the holster body, relative to the first attachment formation, wherein the second attachment formation is dimensioned and configured to render the body operatively securable, adjustably, to the compatible holster accessory. The compatible holster accessory is provided with a corresponding attachment formation, dimensioned and configured to render the compatible holster accessory operatively securable to the opposing sides of the holster body.
