Adjustable Pivoting Gun Stock for Stable Line-of-Sight Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms with fixed gun stocks require users to reposition their shoulders to maintain line-of-sight aiming, leading to increased recoil force, potential injury, reduced accuracy, and decreased response time.
Innovation Solution
An adjustable, pivotable butt-plate system with a ball and socket connection allows for customizable orientation and haptic feedback, enabling stable anchor points and easy re-adjustment to maintain line-of-sight alignment with various sighting apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed gun stock is used, then the structure is simple and stable, but the user must reposition the shoulder to maintain line-of-sight aiming, increasing recoil force and reducing accuracy
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed stock into a dynamic, adjustable system. The stock incorporates a pivot mechanism with a ball joint and socket that allows the stock to rotate and adjust to different angles, enabling the user to maintain proper line-of-sight alignment without repositioning the shoulder. This dynamic adjustment capability resolves the contradiction by providing both operational ease and improved accuracy while managing structural complexity through a focused pivot mechanism.
Solution Approach 2:
The patent applies segmentation by dividing the stock into separate functional components: a fixed base portion attached to the firearm and a movable stock portion that can pivot independently. The ball joint connection separates the rotational adjustment function from the structural support function, allowing the stock to adapt to different shooting positions while maintaining overall structural integrity. This segmentation enables the stock to address line-of-sight alignment issues without requiring complete redesign of the entire firearm structure.
2Measurement precision
If the user repositions the shoulder to maintain line-of-sight aiming, then accuracy can be maintained, but response time decreases and the anchor point becomes unstable during rapid firing
Solution Approach 1:
The dynamic pivot mechanism allows the stock to quickly adjust to the optimal angle for line-of-sight alignment without requiring the user to physically reposition their shoulder. During rapid firing, the stock can dynamically adapt to maintain stability and accuracy, reducing the time loss associated with manual shoulder repositioning while preserving aiming precision through the mechanical adjustment capability.
3Object-affected harmful factors
If recoil pads are used to lessen shock, then comfort increases, but the problem of shoulder repositioning and anchor point stability remains unresolved
Solution Approach 1:
The patent addresses anchor point stability by implementing a dynamic pivot system that actively maintains the stock's alignment with the shoulder during recoil. Rather than passively absorbing shock with a recoil pad, the pivot mechanism allows the stock to dynamically adjust and maintain a stable anchor point throughout the recoil cycle, resolving the contradiction between shock mitigation and anchor point stability by making the support system adaptive rather than static.
