Solution Overview

Problem

Existing firearm accessory mounting systems lack efficient and user-friendly mechanisms for securely attaching and detaching accessories like spare magazines from accessory rails without manual actuation or direct contact.

Innovation Solution

A U-shaped channel accessory holder with a detent system and a clamp assembly that allows for automatic retention and release of accessories, utilizing a U-shaped channel with a first detent for automatic engagement and disengagement, and a clamp fitting for secure attachment to the accessory rail, enabling multiple rotational positions for versatile mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a manual actuation mechanism is used for attaching accessories, then the attachment can be secured reliably, but the operation becomes complex and time-consuming

Engineering Contradiction:
Improveattachment securityVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The accessory holder employs a self-latching mechanism where the U-shaped channel automatically engages with the accessory rail upon insertion. The detent system provides automatic retention without requiring manual actuation, allowing the accessory to secure itself through simple insertion and removal motions.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If a simple attachment mechanism is used, then the operation is easy and quick, but the attachment security and reliability are reduced

Engineering Contradiction:
Improveattachment speedVSAvoidattachment security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The attachment mechanism is divided into distinct functional components: the U-shaped channel for receiving the accessory, the detent system for automatic retention, and the clamp assembly for secure mounting to the rail. This segmentation allows each component to perform its specific function efficiently, combining quick operation with reliable security.

Inventive Principle:
Principle #1Segmentation

3Reliability

If a fixed mounting position is used, then the attachment is stable and secure, but the versatility and adaptability are limited

Engineering Contradiction:
Improvemounting stabilityVSAvoidmounting position flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The clamp assembly incorporates a movable jaw that can be adjusted to different positions along the accessory rail. This dynamic adjustment capability allows the accessory holder to be mounted at various locations while maintaining secure attachment, combining stability with positioning flexibility.

Inventive Principle:
Principle #15Dynamics

4Reliability

If multiple components are used for secure attachment, then the reliability is improved, but the device complexity increases

Engineering Contradiction:
Improveattachment securityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The accessory holder integrates multiple functions into unified components: the U-shaped channel simultaneously provides accessory reception and detent engagement, while the clamp assembly combines mounting and positioning functions. This merging reduces the number of separate parts while maintaining attachment security.

Inventive Principle:
Principle #5Merging (Combining)
