Solution Overview

Problem

Adjusting the retention of hard shell holsters can be problematic, especially when they are rigid and have multiple interlocking shell portions, limiting their ability to flex and provide effective passive retention for handguns.

Innovation Solution

An adjustable retention system with retention devices that include a base and a protruding retention bump, which can be extended or retracted to adjust the retention level, allowing users to interchange devices with different retention values to suit their preferences, and can be temporarily or permanently coupled to the holster.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If hard shell holsters are made rigid with multiple interlocking shell portions, then structural strength and stability are improved, but the ability to flex and provide effective passive retention deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidflexibility
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The retention system is divided into discrete components: multiple retention devices with different retention values, and interchangeable retention elements. This segmentation allows the user to select and combine specific components to achieve the desired retention level, resolving the contradiction between structural rigidity and retention effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retention system transitions from a static, fixed retention design to a dynamic, adjustable retention system. Users can interchange retention elements and adjust retention devices to modify retention characteristics, enabling the rigid holster to adapt to different retention requirements without compromising structural integrity.

Inventive Principle:
Principle #15Dynamics

2Reliability

If retention is increased to securely retain the handgun, then safety is improved, but the ease of drawing the handgun deteriorates

Engineering Contradiction:
Improveretention securityVSAvoidease of drawing
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system provides multiple retention devices with different retention values, allowing users to select the appropriate retention level for their needs. By changing the retention parameter through interchangeable elements, users can optimize the balance between secure retention and ease of drawing according to their specific requirements.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the holster is designed for concealed carry, then safety and protection are improved, but accessibility and ease of use deteriorate

Engineering Contradiction:
Improveconcealment safetyVSAvoidaccessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The adjustable retention system allows users to modify retention characteristics based on the carrying situation. For concealed carry, users can select higher retention values for enhanced security, while for open carry or rapid deployment scenarios, they can reduce retention for faster access, thus dynamically balancing concealment safety with accessibility.

Inventive Principle:
Principle #15Dynamics

AI summary

Representative implementations of devices and techniques provide an adjustable retention system for an implement holster (such as a handgun holster, for example). The retention device of the adjustable retention system can be temporarily or permanently coupled to a holster, and includes at least one retention bump protruding from a surface of a base of the device.
