Solution Overview
Problem
Firearm operators face excessive recoil energy from weapons, leading to reduced performance and safety concerns due to the inability to adequately control the firearm, which existing technologies have not adequately addressed.
Innovation Solution
A recoil reduction system for small arms weapons, comprising a drive assembly and a recoil force storage apparatus with a strut assembly including a coil spring, offering three selectable operational modes for varying levels of recoil reduction by configuring the recoil force storage apparatus in different arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a firearm is designed to generate high recoil energy for effective operation, then the weapon achieves sufficient stopping power and range, but the operator experiences reduced control and safety due to excessive recoil
Solution Approach 1:
The recoil reduction system captures the harmful recoil energy generated by the firearm and converts it into useful work by compressing a spring mechanism. The drive link transfers recoil forces from the receiver to the stock, compressing the spring which then returns energy to propel the stock forward, effectively converting the harmful rearward recoil force into a beneficial forward-releasing action that reduces perceived recoil.
Solution Approach 2:
The drive link acts as an intermediary mechanism between the receiver and the stock. It transfers and modifies the recoil forces, introducing a mechanical mediation system that includes the spring-loaded recoil reduction apparatus. This intermediary system decouples the direct transmission of recoil forces from the operator's shoulder, allowing for controlled energy management.
2Ease of operation
If recoil reduction mechanisms are added to mitigate recoil energy, then operator control and safety are improved, but the device complexity increases
Solution Approach 1:
The recoil reduction system is integrated into the existing stock structure, with the spring mechanism serving multiple functions: absorbing recoil energy, providing a return force to propel the stock forward, and potentially serving as part of the stock's structural framework. The drive link also serves dual purposes by connecting the receiver to the stock while simultaneously transmitting and modulating recoil forces.
Solution Approach 2:
The recoil reduction components are nested within the stock assembly. The spring is housed within the stock structure, and the drive link operates within the confines of the receiver-stock interface. This nested arrangement minimizes the external footprint of the recoil reduction system while maintaining its functionality within the existing firearm geometry.
