Solution Overview

Problem

Existing holster systems fail to securely retain handguns and accessories, particularly when subjected to rearward forces, and often require manual reset after use, lacking versatility to accommodate various handgun models and accessories.

Innovation Solution

A universal holster system with a retention mechanism featuring a spring-loaded blocking portion and thumb-actuated release mechanism, which automatically locks the handgun in place and allows secure withdrawal, while accommodating different handgun and accessory configurations without manual reset.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a retention mechanism is designed to securely retain the handgun against rearward forces, then the handgun cannot be accidentally dislodged, but it becomes difficult to withdraw when needed

Engineering Contradiction:
Improvehandgun retention securityVSAvoidhandgun withdrawal ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The retention mechanism uses a dynamic blocking portion that can move between a blocking position (preventing withdrawal) and a non-blocking position (allowing withdrawal). The spring member enables the blocking portion to dynamically respond to forces applied to the handgun, automatically engaging to prevent accidental dislodging while allowing intentional removal when the trigger guard is actuated.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The blocking portion is positioned to preemptively prevent rearward movement of the handgun before such movement can occur. The spring-loaded mechanism anticipates potential dislodging forces and applies counteracting retention force, while the connection to the trigger guard ensures that the preliminary blocking action can be readily reversed when needed.

Inventive Principle:
Principle #9Preliminary anti-action

2Adaptability or versatility

If a holster system is designed to accommodate various handgun models and accessories, then versatility is improved, but the retention mechanism complexity increases

Engineering Contradiction:
Improvehandgun model compatibilityVSAvoidretention mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The retention mechanism serves multiple functions: it retains the handgun body, secures the accessory mounted on the handgun, and provides automatic resetting capability. The blocking portion is positioned to engage with features common to various handgun models and accessories, allowing a single holster design to accommodate different configurations without requiring model-specific adjustments.

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

Solution Approach 2:

The spring member automatically resets the blocking portion to its blocking position after the handgun is reholstered, eliminating the need for manual resetting by the user. The mechanism self-activates upon insertion, engaging the retention function automatically, and self-resets upon removal, reducing operational complexity for the user.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the blocking portion is spring-loaded to automatically engage, then ease of operation is improved, but the force required to prevent accidental disengagement increases

Engineering Contradiction:
Improveretention engagement easeVSAvoidretention force
Core Design Contradiction:
Ease of operationVSForce

Solution Approach 1:

The spring member provides a dynamic retention force that automatically engages the blocking portion without requiring user action. The spring force is calibrated to provide sufficient retention to prevent accidental disengagement while allowing the blocking portion to be moved when deliberate force is applied through trigger guard actuation. The spring continuously maintains engagement pressure, creating a self-regulating retention system.

Inventive Principle:
Principle #15Dynamics

AI summary

A holster system that comprises a holster and an accessory configured to be fixed to a mounting rail of a handgun. The holster has a holster body with a pair of opposing wall portions defining a cavity. A retention mechanism of the system has a blocking portion movable between a blocking position and a non-blocking position. The blocking member at least inhibits removal of the handgun and accessory if the handgun and accessory are urged rearwardly before a thumb receiving portion is depressed. The blocking portion is on a spring member that is deflected by an elongate exteriorly extending sliding member that has a cam surface that selectively deflects the spring member from the blocking position.
