M240 Machine Gun Trigger Housing Forward Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The M240 machine gun has a design that results in unnecessary length and weight, making it cumbersome and difficult to transport, especially in combat situations, due to the trigger and grip being located near the rear of the firearm.
Innovation Solution
An adapter system that moves the trigger housing assembly forward, allowing for a shorter overall length and improved ergonomics by relocating the trigger and grip closer to the muzzle, which can include a new receiver design with an adapter replacing the bottom plate or using an extended trigger housing assembly with a proximal leg to attach to the existing receiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the trigger and grip are located near the rear of the firearm, then the length of pull is sufficient, but the overall length and weight increase making it cumbersome
Solution Approach 1:
The firearm is divided into modular components including a receiver, stock, and trigger housing assembly that can be independently positioned. The trigger housing assembly is separated from the stock and can be mounted at different locations along the receiver, allowing the length of pull to be maintained while reducing overall firearm length and weight.
Solution Approach 2:
The trigger housing assembly is repositioned from the traditional rear location to a forward location on the receiver, changing the spatial dimension of the trigger-grip-stock arrangement. This dimensional reconfiguration allows the stock to be shorter while maintaining adequate length of pull through the relocated trigger assembly.
2Ease of operation
If the trigger and grip are located near the rear of the firearm, then the length of pull is sufficient, but the firearm becomes difficult to transport
Solution Approach 1:
The trigger housing assembly is segmented from the stock and receiver structure, allowing it to be independently positioned forward on the receiver. This segmentation enables the stock length to be reduced while the trigger assembly maintains proper positioning relative to the grip, achieving shorter overall length without sacrificing length of pull.
Solution Approach 2:
By relocating the trigger housing assembly forward along the receiver's longitudinal axis, the patent changes the dimensional arrangement of components. This allows the stock to be shortened significantly while the trigger remains positioned to provide adequate length of pull, reducing the firearm's overall length for easier transport.
3Length of moving object
If the trigger housing assembly is moved forward, then the overall length decreases, but the traditional receiver design must be modified
Solution Approach 1:
The trigger housing assembly is designed as a separate, modular component that interfaces with the receiver through standardized mounting points. This segmentation allows the trigger assembly to be repositioned forward without requiring complete redesign of the receiver, as the modular interface simplifies the integration process.
Solution Approach 2:
The receiver is designed with universal mounting features that can accommodate the trigger housing assembly at multiple positions along its length. This multi-functional capability allows the same receiver design to support both traditional rear-mounted and forward-mounted trigger configurations, reducing the complexity of modification required.
