Hand-Held Gun Breech Buffer Design for Compact Recoil Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recoil forces during firing in hand-held guns, particularly those with high penetrating power or large caliber, affect marksmanship and require improved damping without compromising the compact configuration of the weapon.
Innovation Solution
A hand-held gun design featuring a breech part movably supported on a grip part with a breech spring arrangement and an elastically deformable buffer body that dampens recoil forces through a combination of breech spring compression and buffer body compression, reducing maximum recoil by up to 80% compared to similar constructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a compact construction is used for hand-held guns, then the weapon size is reduced, but recoil forces increase and affect marksmanship
Solution Approach 1:
The patent implements a buffer body made of elastomeric material positioned in the grip part that compresses during recoil to dampen rearward movement of the breech part. This cushioning element is pre-positioned to engage during the recoil cycle, absorbing shock and reducing the impact on the shooter before the full recoil force is transmitted to the hand.
Solution Approach 2:
The patent changes the physical parameters of the recoil management system by introducing an elastomeric buffer body with specific material properties (durometer hardness, density, geometry). These parameter changes allow the buffer to deform under recoil forces, providing progressive resistance that dampens the recoil impulse while maintaining a compact overall weapon configuration.
2Strength
If high penetrating power ammunition or large caliber is used, then stopping power is improved, but recoil forces increase significantly
Solution Approach 1:
The elastomeric buffer body is positioned to engage during the initial phase of recoil, providing cushioning that dampens the rearward movement of the breech part before it can build up excessive velocity. This allows the use of high-caliber or high-penetration ammunition while reducing the perceived recoil impact on the shooter.
Solution Approach 2:
The buffer body's material parameters (durometer 40-90, density 0.8-1.2 g/cm³) and geometric parameters are selected to provide progressive resistance during compression. This allows the system to handle the high impulse forces generated by large caliber or high penetrating power ammunition while maintaining controllability and reducing recoil effects.
3Device complexity
If traditional spring arrangements are used for recoil management, then the construction is simple, but maximum recoil forces are not sufficiently reduced
Solution Approach 1:
The patent replaces or supplements traditional metallic spring arrangements with an elastomeric buffer body that utilizes the viscoelastic properties of rubber-like materials. This substitution provides superior recoil damping through material deformation rather than purely mechanical spring compression, reducing maximum recoil forces by up to 80% compared to conventional designs while maintaining relative simplicity.
Solution Approach 2:
The elastomeric buffer body can be constructed from composite materials or multi-layer elastomeric structures that combine different material properties to optimize both damping performance and structural integrity. This allows for tailored recoil characteristics while keeping the overall device complexity manageable.

AI summary
A hand-held gun having a grip part and a breech part movably supported in a longitudinal direction thereon is disclosed. A breech spring arrangement urges breech part in its initial position relative to grip part. For this purpose, breech spring arrangement is supported between the breech part and grip part. Starting from the initial position, breech part can move against the closing force of breech spring arrangement into an abutment position in which it abuts against a buffer body. Starting from the abutment position, breech part can be moved under elastic compression of buffer body in the longitudinal direction into a retracted position. In the movement area between the abutment position and the retracted position, a compression force is applied by the compressed buffer body in addition to the closing force of the breech spring arrangement between the grip part and the breech part.
