Electromagnetic Recoil Reduction in Firearms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms experience significant recoil force during firing, causing physical stress and reducing accuracy, especially when firing multiple rounds quickly, and existing recoil pads do not effectively reduce this force.
Innovation Solution
An electromagnetic system is integrated into the firearm, comprising a first electromagnet unit with a conducting coil and magnet, and a second electromagnet unit with a generator coil and magnet, which generates a magnetic field to oppose the bolt's rearward movement, reducing recoil force and utilizing induced current to power the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If an electromagnetic system is added to reduce recoil, then recoil force is reduced, but device complexity increases
Solution Approach 1:
The patent combines the recoil reduction function with the existing firearm structure by integrating the electromagnet system into the stock and action assembly. The first electromagnet unit is mounted in the stock while the second unit is integrated with the bolt carrier group, merging multiple functions into a unified system that reduces recoil without requiring separate standalone components.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary force between the bolt carrier group and the stock. The electromagnet units generate controlled magnetic fields that act as a mediator to oppose the rearward movement of the bolt during recoil, providing a smooth and adjustable damping effect without direct mechanical contact.
2Force
If a recoil reduction system is integrated into the firearm structure, then recoil force is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent divides the recoil reduction system into two separate electromagnet units: a first unit integrated into the stock and a second unit integrated with the bolt carrier group. This segmentation allows each unit to be manufactured and tested independently, then assembled into the complete firearm system, simplifying the overall manufacturing process.
Solution Approach 2:
The electromagnet units are designed with multi-functionality, serving both as structural components of the firearm and as active recoil reduction elements. The first electromagnet unit reinforces the stock structure while providing magnetic damping, and the second unit is integrated with the bolt carrier group to provide both structural support and recoil opposition, reducing the need for additional specialized components.

Function Achieved in This Case
The electromagnetic system effectively reduces the recoil force felt by the user, improving comfort and accuracy during rapid firing by using magnetic opposition and induced energy to mitigate the recoil impact.
Implementation Method 1
a first electromagnet unit comprising a conducting coil and a magnet, wherein the magnet is coupled to the bolt, and wherein the conducting coil is configured to generate a magnetic field that opposes a movement of the bolt from the forward position to the rearward position
Implementation Method 2
a second electromagnet unit comprising a generator coil, a generator magnet, and a connector connecting the generator magnet to the bolt such that movement of the bolt causes movement of the generator magnet, wherein the movement of the generator magnet is configured to induce a current in the generator coil

AI summary
An electromagnetic system coupled to a firearm, the firearm including a bolt movable rearward and frontward along a rear-to-front axial direction between a forward position and a rearward position, includes a first electromagnet unit. The first electromagnet unit includes at least one electrically-conductive coil and at least one magnet. The magnet or magnets are movable jointly with the bolt in the axial direction with respect to the at least one electrically-conductive coil. The at least one electrically-conductive coil is configured to generate at least one magnetic field that opposes a rearward movement of the at least one magnet in the axial direction and thereby reduces a rearward recoil of the bolt.
