Firearm Barrel Tray with Accessory Mounting Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a lightweight firearm stock that allows secure attachment of accessories to the forward region without increasing the overall weight of the firearm, as existing mounting systems using heavy, durable materials can make the firearm too heavy.
Innovation Solution
A firearm barrel tray and stock system where the barrel tray is made of a stronger material than the stock, with a barrel channel on one side and an accessory mounting interface on the other, allowing for secure attachment of accessories while minimizing weight and cost, using high-strength materials like engineering grade polymers and metal alloys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heavy, durable materials are used for mounting systems, then accessory attachment security is improved, but firearm weight increases
Solution Approach 1:
The mounting system is divided into separate components: a barrel tray made of heavy, durable material (aluminum or steel) and a stock made of lightweight material (polymer or wood). This segmentation allows the heavy material to be used only where structural strength is needed for accessory mounting, while the rest of the firearm remains lightweight.
Solution Approach 2:
Different materials are used for different parts of the firearm based on local requirements. The barrel tray uses heavy, durable material where accessory attachment security is critical, while the stock uses lightweight material where weight reduction is prioritized. This local differentiation resolves the contradiction between overall weight and localized strength requirements.
2Stability of the object's composition
If heavy, durable materials are used for the entire stock, then accessory mounting stability is improved, but firearm weight and cost increase
Solution Approach 1:
The firearm is segmented into two distinct components with different material properties: a stable, heavy barrel tray for accessory mounting and a lightweight stock for portability. This segmentation eliminates the need to make the entire stock heavy while maintaining mounting stability.
Solution Approach 2:
The system uses composite construction combining different materials (metal or polymer tray with polymer or wood stock) to achieve both stability and weight reduction. The composite structure allows each material to be used where it provides the most benefit.
3Manufacturing precision
If heavy, durable materials are used for mounting systems, then movement tolerance during firing is reduced, but firearm weight increases
Solution Approach 1:
The heavy, durable material is segmented and applied only to the barrel tray and accessory interface components where precision and low movement tolerance are critical. The stock remains lightweight, achieving overall weight reduction while maintaining precision where needed.
Solution Approach 2:
High-quality, heavy materials are applied locally to the barrel tray and mounting interface where movement tolerance during firing is most critical, rather than throughout the entire firearm. This local quality approach maintains manufacturing precision while reducing overall weight.
