Shooting Rest Rear Stop with Resilient Recoil Pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearm shooting sports are hindered by painful recoil, which existing shooting rests do not adequately address, leading to discomfort and inaccuracy due to the recoil force felt by shooters, especially when firing high-caliber firearms.
Innovation Solution
A shooting rest with a rear support featuring a recoil pad made of thermoplastic material with a durometer between 20 Shore A and 60 Shore A, providing a resilient cushion that absorbs recoil, and a stop to inhibit rearward movement of the firearm, combined with a weight support to augment recoil absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a shooting rest is used to support the firearm, then the firearm stability is improved, but the recoil force is still strongly felt by the shooter causing discomfort and inaccuracy
Solution Approach 1:
A recoil pad made of resiliently compressible material (thermoplastic, foam, rubber, or spring mechanism) is introduced as an intermediary between the firearm butt and the shooter's shoulder. This mediator absorbs and cushions the recoil force, reducing the harmful impact to the shooter while maintaining firearm stability through the stop mechanism.
Solution Approach 2:
The recoil pad changes the physical parameters of the interface between firearm and shooter by introducing compliant, resilient material properties. The material's compressibility and elasticity parameters allow it to deform under recoil force, absorbing energy and reducing the peak force transmitted to the shooter's shoulder.
2Object-affected harmful factors
If a stop is added to inhibit rearward movement of the firearm, then the recoil absorption is improved, but the device complexity increases
Solution Approach 1:
The shooting rest is segmented into distinct functional components: a support structure for stability, a stop mechanism for recoil absorption, and an optional recoil pad for additional cushioning. This segmentation allows each component to perform its specific function independently, simplifying the overall design and making the system easier to manufacture and adjust.
Solution Approach 2:
The recoil absorption function is extracted as a separate, removable component (the stop with recoil pad) that can be independently adjusted or removed. This allows the basic shooting rest to remain simple while offering enhanced recoil management when needed, without permanently increasing the core structure's complexity.
3Object-affected harmful factors
If a thick resilient cushion is used for the recoil pad, then the recoil cushioning is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The cushion's thickness and material durometer are specified as adjustable parameters within defined ranges (0.25-2.5 inches thick, 20-60 Shore A durometer for thermoplastic). These parameter specifications provide manufacturing flexibility, allowing producers to create effective recoil pads without requiring ultra-precise dimensional control, as the resilient material compensates for minor variations.
Solution Approach 2:
Multiple material options are provided for the recoil pad including thermoplastic, foam, rubber, and spring mechanisms. These composite and alternative material choices allow manufacturers to select materials that are easier to produce with consistent performance characteristics, reducing the need for high-precision manufacturing while maintaining effective recoil cushioning.
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 shooting rest significantly reduces the recoil force felt by the shooter, providing improved accuracy and comfort by effectively absorbing and distributing the recoil force, tested to reduce recoil by about 30% compared to similar supports without a recoil pad.
Implementation Method 1
The recoil pad includes a resiliently compressible cushion positioned in front of the rear panel
Implementation Method 2
The cushion includes thermoplastic material having a durometer between about 20 Shore A and about 60 Shore A
