Firearm Buffer With Magnetic Bias for Bounce Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms experience inertial events during firing and reloading, leading to unwanted bounce and acceleration issues that affect shooting accuracy and timing, which existing buffer systems fail to adequately mitigate.
Innovation Solution
A buffer assembly incorporating a magnetic dead-blow mechanism with at least one weight and two magnets, where the magnetic repelling force biases the weight to an at-rest position, allowing it to overcome the bias and achieve a dead-blow condition to offset inertial events, adjusting impact force and delay intervals to minimize bounce and optimize firearm operation.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional buffer system is used to mitigate inertial events, then some cushioning effect is provided, but bounce and acceleration issues are not adequately controlled
Solution Approach 1:
The patent replaces a purely mechanical buffer system with a hybrid system incorporating magnetic fields. Magnets are positioned within the buffer assembly to create magnetic repulsion forces that actively counteract inertial events, providing more precise control over bounce and acceleration compared to traditional mechanical springs alone.
Solution Approach 2:
The patent modifies the buffer system by introducing magnetic field parameters (magnet strength, positioning, polarity) in addition to traditional mechanical parameters. This allows for fine-tuning the response characteristics to optimize the delay interval and impact force, thereby better controlling bounce while maintaining shooting accuracy.
2Object-affected harmful factors
If the buffer responds immediately to inertial events, then bounce is reduced, but the timing may not be optimized for shooting accuracy
Solution Approach 1:
The patent creates a dynamic response system where the magnetic repulsion force is activated with a specific delay interval after the inertial event begins. This delayed activation allows the buffer to respond at the optimal moment in the firing cycle, reducing bounce while maintaining accurate timing for shooting.
Solution Approach 2:
The buffer system operates in periodic cycles corresponding to the firing action, with the magnetic dead-blow mechanism activating at specific intervals. The delay interval is calibrated to match the periodic nature of firearm operation, ensuring bounce reduction occurs at the most effective moment without disrupting the overall timing.
3Object-affected harmful factors
If the impact force is increased to offset inertial events, then bounce is reduced, but the magnitude may be excessive and cause new problems
Solution Approach 1:
The magnetic field provides a controllable and adjustable repulsion force that can be fine-tuned to match the magnitude of inertial events. By adjusting magnet strength and positioning, the system delivers the precise amount of counter-force needed to offset bounce without creating excessive impact forces that could cause new problems.
Solution Approach 2:
The patent allows for adjustment of magnetic field parameters (magnet size, material, positioning distance) to precisely control the impact force magnitude. This enables optimization of the dead-blow effect to provide just enough force to counteract inertial events without overshooting and creating new issues.
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
The magnetic dead-blow mechanism effectively reduces bounce and slows down acceleration, improving shooting accuracy and optimizing the firing action by fine-tuning the delay interval and impact force to partially offset inertial events, thereby enhancing the firearm's operational efficiency.
Implementation Method 1
a magnetic repelling force between the first magnet and the second magnet biases the weight to an at-rest position within the internal assembly
Implementation Method 2
in response to an inertial event the at least one weight overcomes the bias of the magnetic repelling force to achieve a dead-blow condition
