Solution Overview

Problem

The existing methods for attaching accessories to a Magpul MLOK rail on a firearm are cumbersome, require external tools, and can be dangerous in combat situations where quick attachment or switching of accessories is necessary.

Innovation Solution

A mounting device with an upper and lower portion, and locking mechanisms comprising a releasing pin, spring, and wedge, allowing for quick and tool-free attachment and detachment with single-handed operation, enhancing safety and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional mounting methods are used to attach accessories to MLOK rail, then secure attachment is achieved, but the process requires external tools and is time-consuming

Engineering Contradiction:
Improvesecure attachmentVSAvoidattachment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The mounting device enables self-service operation where the user can attach and detach accessories using only the hands, without requiring external tools. The releasing pin mechanism allows the user to manually actuate the locking mechanism, making the system self-sufficient and eliminating dependency on additional tools.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The mounting device transitions from a static locked state to a dynamic unlocked state through the action of the releasing pin. The spring-loaded wedge mechanism allows for quick transition between states, enabling rapid attachment and detachment while maintaining secure locking when engaged.

Inventive Principle:
Principle #15Dynamics

2Reliability

If traditional mounting methods are used, then secure attachment is achieved, but external tools are required which complicates the operation

Engineering Contradiction:
Improvesecure attachmentVSAvoidoperation simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The device is designed to be operated solely by hand without requiring external tools. The releasing pin can be manually actuated by the user to unlock and remove the accessory, and can be manually pushed back to lock it in place, making the entire operation self-service and tool-free.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The releasing pin is extracted as a separate manually-operated component that can be actuated independently to unlock the mounting device. This extraction of the locking function into a separate accessible component simplifies operation by allowing direct manual control without needing external tools.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If traditional mounting methods are used, then attachment is secure, but the process is awkward and cannot be performed with single hand

Engineering Contradiction:
Improvesecure attachmentVSAvoidsingle-handed operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mounting device is designed to be completely operable with one hand. The releasing pin can be actuated by thumb or finger pressure, and the wedge mechanism responds automatically to the applied force, allowing a single user to securely attach or detach accessories without needing a second hand for tool manipulation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The spring-loaded wedge mechanism provides dynamic response to the user's input force on the releasing pin. When the pin is actuated, the wedge automatically moves to unlock, and when the pin is released, the spring automatically returns the wedge to the locked position, enabling easy single-handed operation while maintaining secure attachment.

Inventive Principle:
Principle #15Dynamics

4Productivity

If quick-release mechanism is implemented, then attachment speed is improved, but device complexity increases

Engineering Contradiction:
Improveattachment speedVSAvoidmounting device structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The mounting device is segmented into distinct functional components: the releasing pin for actuation, the wedge for locking/disllocking action, and the spring for automatic reset. This segmentation allows each component to perform its specific function efficiently, achieving quick-release capability while keeping the overall structure relatively simple and modular.

Inventive Principle:
Principle #1Segmentation
