Segmented Buffer Bumper Assembly for Recoil Energy Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recoil-based buffer systems in firearms are inadequate as they do not effectively manage stress and energy transfer during recoil, are temperature-sensitive, and require costly replacements, making them unreliable across various environmental conditions.
Innovation Solution
A buffer bumper assembly with an upper and lower segment, a biasing structure, and a connector that allows reciprocal movement, enabling the biasing structure to absorb energy during recoil, reducing the impact on the weapon and eliminating the need for complete buffer replacement, with components designed to function effectively regardless of environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional buffer bumper assembly is used, then the buffer can absorb some recoil energy, but the buffer cannot effectively manage stress and energy transfer during recoil, and requires costly complete replacement
Solution Approach 1:
The buffer bumper assembly is divided into multiple segments including a first segment, second segment, third segment, and fourth segment. These segments can move relative to each other and work in conjunction with springs to progressively absorb and manage recoil energy, replacing the need for complete buffer replacement after impact.
Solution Approach 2:
Springs are pre-positioned between the buffer segments to provide cushioning before impact occurs. During recoil, these springs compress to absorb energy, preventing direct hard impact and reducing stress on the weapon system, thereby eliminating the need for costly buffer replacements.
2Adaptability or versatility
If existing buffer systems are used, then the buffer can be adjusted for different calibers, but the systems are temperature-sensitive and unreliable across various environmental conditions
Solution Approach 1:
The buffer bumper assembly incorporates movable segments that can dynamically adjust their positions relative to each other during recoil. This dynamic structure allows the buffer to adapt to different recoil energies from various calibers while maintaining consistent performance across different environmental conditions through progressive energy absorption.
3Speed
If a heavier buffer is used to add mass to the reciprocating assembly, then the recoil pulse can be slowed, but the buffer creates greater impact force against the buffer tube
Solution Approach 1:
Springs are pre-positioned between buffer segments to provide cushioning before impact. During recoil, these springs compress to absorb energy, allowing the use of sufficient buffer mass to slow the recoil cycle while preventing the transmission of excessive impact forces to the buffer tube through progressive energy absorption.
Solution Approach 2:
The segmented buffer structure distributes the mass and impact forces across multiple segments that move relative to each other. This segmentation allows the buffer to maintain sufficient overall mass for recoil control while reducing peak impact forces through the progressive compression of springs between segments.

AI summary
A buffer bumper assembly for use with some firearms that incorporate a recoil based operating system. The buffer bumper assembly may be disposed on a buffer bumper structure that may be installed inside of a recoil spring around an end thereof. The buffer bumper assembly comprises an upper segment, a lower segment, a biasing structure and a connector. The upper segment and lower segment are interconnected with the connector and reciprocally movable to one another. The upper segment and lower segment may be collectable disposable into and out of a compressed position and an uncompressed position. The biasing structure may at least partially assume the energy of an impact associated with a recoil cycle when it is compressed and when the upper segment and lower segment are collectively disposed in the compressed position.
