Adjustable Buffer System Spring Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The typical buffer system in firearms, such as the AR-15, does not allow users to adjust the preload or tension of the buffer spring, which limits the customization of recoil action and bolt lock time.
Innovation Solution
An adjustable buffer system is introduced, featuring a slidable collar that can be moved along the buffer body to adjust the compression of the buffer spring, allowing increased spring pressure and reducing recoil, compatible with various barrel lengths and gas tube configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed buffer spring is used in the buffer system, then the structure is simple and reliable, but the user cannot adjust the preload or tension to customize recoil action and bolt lock time
Solution Approach 1:
The patent applies the dynamics principle by making the buffer spring preload adjustable rather than fixed. The buffer assembly includes a buffer spring, buffer, and adjustment mechanism that allows the user to change the spring tension according to different operational requirements, transforming a static system into a dynamic one that can adapt to varying recoil and bolt lock time needs
Solution Approach 2:
The patent implements parameter changes by providing an adjustment mechanism that modifies the preload parameter of the buffer spring. This allows users to change the tension parameter of the spring to achieve different recoil characteristics and bolt lock times, enabling customization without changing the fundamental buffer spring component itself
2Object-affected harmful factors
If the buffer spring compression is increased to reduce recoil, then the recoil action is softened, but the bolt lock time may be extended and the system becomes less adaptable to different barrel lengths
Solution Approach 1:
The patent uses parameter changes to adjust the buffer spring preload independently of the spring compression distance. By providing an adjustment mechanism that modifies the preload parameter, the system can reduce recoil impact through increased spring tension without necessarily increasing compression, thereby maintaining adaptability across different barrel lengths and gas tube configurations
Solution Approach 2:
The adjustable buffer assembly allows dynamic adjustment of the buffer spring preload to match different firearm configurations. This dynamic capability enables the system to optimize recoil reduction for each specific barrel length and gas tube setup rather than being fixed at a single compression level that would compromise adaptability
