Side Slide Lock for Firearms Using Spring-Loaded Latches

Solution Overview

Problem

The existing methods for mounting accessories like scopes, lights, and bayonets on firearms require external tools, making the process time-consuming and potentially dangerous, especially in combat situations, where quick attachment is crucial.

Innovation Solution

A quick release attachment device comprising a lower and upper portion with a locking mechanism, including a handle, latches with springs, and a button lock, allowing for secure attachment and detachment without external tools, enabling single-handed operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

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

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The locking mechanism is designed to be self-operating through spring-loaded latches that automatically engage with the Picatinny rail when the accessory is mounted. The system uses its own internal springs and latches rather than requiring external tools, allowing the user to simply press the accessory onto the rail and the locking mechanism self-activates

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The locking mechanism transitions from a static locked state to a dynamic unlocked state through a release button that compresses the spring-loaded latches. This dynamic mechanism allows quick transition between locked and unlocked states without tools, enabling rapid attachment and detachment while maintaining secure locked positioning 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 operation

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs its own locking function through spring-loaded latches that automatically engage with the rail features when the accessory is pressed onto the mount. No external tools are needed as the mechanism uses its own internal components to achieve secure attachment

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The external tool requirement is completely removed from the system. The mounting mechanism is redesigned to eliminate the need for screwdrivers, hex keys, or other external tools by using spring-loaded latches that engage directly with the Picatinny rail features through simple pressing motion

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If quick release mechanism is implemented, then mounting speed is improved, but risk of accidental release increases

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The release button mechanism requires deliberate intentional action to unlock - the user must actively press the button against spring resistance to release the latches. This preliminary anti-action prevents accidental release while maintaining quick intentional release capability, as the system is designed to resist unintended activation

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The locking mechanism uses spring-loaded latches that dynamically transition between locked and unlocked states. The springs provide continuous locking force during normal operation, and the dynamic release button allows controlled transition to unlocked state only when deliberately activated, balancing quick release with accidental prevention

Inventive Principle:
Principle #15Dynamics

4Reliability

If two-handed operation is required, then secure locking is achieved, but usability in combat situations is reduced

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The spring-loaded latches automatically engage and lock the accessory to the Picatinny rail when the user presses the mount onto the rail. The system self-performs the locking action without requiring the user to manually manipulate multiple components or use both hands

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The release button serves multiple functions: it unlocks the latches for removal, and can be pressed with either hand. The mechanism is designed to be universally operable with one hand regardless of which hand the user prefers, making it adaptable to different combat situations and user preferences

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