Spring-Loaded Folding Firearm Rapid Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior folding firearms are slow to deploy manually and lack a streamlined design due to a single out-of-profile hinge, making them unsuitable for rapid deployment in surprise situations.
Innovation Solution
A spring-loaded folding firearm with a dual hinge mechanism and a combined charging/deployment handle allows for rapid, single-handed deployment, featuring a hinged back plate that serves as a cheek rest and utilizing aftermarket GLOCK parts for ease of repair and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If manual deployment mechanism is used, then device complexity is reduced, but deployment speed becomes prohibitively slow
Solution Approach 1:
The firearm components are pre-positioned and spring-loaded in the folded configuration, so that upon activation, the decomposition and deployment actions occur rapidly without requiring manual manipulation of multiple components during the deployment moment
Solution Approach 2:
The firearm uses its own internal springs and mechanical energy storage to automatically drive the decomposition and deployment process, eliminating the need for external manual force or complex motorized systems
2Shape
If single hinge design is used, then device complexity is reduced, but design streamlining is inhibited
Solution Approach 1:
The hinge system is divided into multiple sequential hinges that enable the firearm to decompose into compact segments for streamlined storage, while maintaining structural integrity and aesthetic lines when folded
Solution Approach 2:
The firearm transitions from a linear extended configuration to a compact folded configuration by utilizing multi-axis hinge rotations, achieving streamlined profile through spatial reconfiguration rather than simple single-axis folding
3Speed
If rapid deployment mechanism is added, then deployment speed is improved, but ease of operation deteriorates
Solution Approach 1:
The deployment function is extracted from the charging handle operation, allowing the charging handle to serve its primary function of cocking the firearm while a separate, simplified mechanism handles the rapid deployment of folded components
Solution Approach 2:
The charging handle is designed to perform multiple functions: traditional charging/cocking operation and initiation of the rapid deployment sequence, consolidating control functions into a single familiar interface that maintains ease of operation
4Reliability
If ammunition feed remains engaged during storage, then ease of operation is improved, but safety deteriorates
Solution Approach 1:
The firearm automatically disengages the ammunition feed from the chamber during the folding and storage sequence, preemptively preventing any possibility of accidental discharge while in compact storage configuration
Solution Approach 2:
The ammunition feed engagement state dynamically changes based on the firearm configuration: automatically disengaged during folding/storage and automatically re-engaged during deployment, adapting to safety requirements of each state without manual intervention
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables compact storage with rapid, single-handed deployment and enhanced safety through a closed-bolt action that disengages the ammunition feed when stowed, ensuring the firearm is ready for use without accidental firings.
Implementation Method 1
spring loaded when stowed and rapidly deploys in a fire ready configuration

AI summary
The present invention is a spring-biased folding firearm that stows compactly and safely. The firearm has three main components: a stock, a receiver and a grip/magazine combination. In folding, the stock folds over the receiver, sandwiching the grip/magazine between the components. When folded, the magazine over-inserts into the grip housing, allowing the stock to clear and providing additional safety when stowed by isolating the ammunition feed. A buttplate latches over the open joint to contain the unit and further secure it. When stowed, the bolt is disengaged from the ammunition feed supply, preventing accidental firing, so a loaded round can be safely carried in the chamber—allowing for immediate use of the firearm upon opening. The weapon is deployed through single-handed actuation and is spring-assisted into firing position. Currently the firearm uses readily available aftermarket parts for easier replacement if necessary and does contain hardware for mounting accessories.
