Bendable Firearm Off-Axis Shoulder Rest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional swivelable firearms face challenges in stable aiming and firing due to unique recoil patterns and difficulty in holding the shoulder rest, which limits their use to small firearms and exposes the user's body during firing, making them unsafe and inefficient.
Innovation Solution
A bendable firearm design with an off-axis shoulder rest and sight system, where the shoulder rest is bent in an off-axis shape and coupled using an adaptable mechanism, allowing direct recoil transmission and minimizing user exposure, combined with a periscope-type sight for stable aiming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional swivelable firearm with L-shaped shoulder rest is used, then the firearm can enable aiming from a shelter position, but the recoil is transmitted in a turned direction causing unstable aiming and firing
Solution Approach 1:
The shoulder rest is designed to be bendable rather than fixed in an L-shape, allowing it to adapt dynamically to different firing positions while maintaining proper alignment. The bendable connection enables the shoulder rest to transition between straight and bent configurations, resolving the contradiction between adaptability for shelter positioning and stability for recoil management.
Solution Approach 2:
The invention introduces an off-axis bending dimension to the shoulder rest configuration. Instead of the conventional L-shaped 90-degree bend, the shoulder rest can bend at various angles and positions along its length, adding dimensional flexibility. This allows the firearm to aim from shelter positions while maintaining proper recoil transmission alignment through strategic bending points.
2Adaptability or versatility
If a conventional swivelable firearm is used, then the firearm can be positioned for shelter firing, but the shoulder rest cannot be stably held against the user's shoulder requiring arm support and both-hand gripping
Solution Approach 1:
The bendable shoulder rest can dynamically adjust its shape to conform to the user's shoulder contours, creating a stable interface without requiring arm support. The flexibility allows the shoulder rest to adapt to different user anatomies and firing positions, making the firearm easy to operate with proper shoulder support even when positioned for shelter firing.
3Adaptability or versatility
If conventional aiming devices such as angle sight or off-axis viewing device are added, then aiming at angled positions is enabled, but much time is required to aim at a target due to left-right reflection of light
Solution Approach 1:
The bendable shoulder rest with off-axis configuration enables dynamic aiming at various angles without requiring separate aiming devices. By adjusting the bend angle and position of the shoulder rest, the user can directly aim at targets at different angles while maintaining proper optical alignment, eliminating the time-consuming left-right reflection issue associated with conventional angle sights.
4Object-affected harmful factors
If the user hides behind a shelter to aim and fire, then the user can monitor and chase the target, but the hand and arm region are inevitably exposed and impacts are not properly controlled
Solution Approach 1:
The bendable shoulder rest allows the user to maintain a protected position behind shelter while dynamically adjusting the firearm orientation for proper recoil control. The flexible connection enables the user to position the firearm at optimal angles for recoil management without exposing the hand and arm, as the shoulder rest absorbs and redirects recoil forces through its bendable structure.
Solution Approach 2:
The bendable shoulder rest acts as an intermediary between the firearm and the user's shoulder, mediating the transmission of recoil forces. It can bend to redirect recoil forces away from exposed body parts while maintaining firing capability, thus protecting the user from both exposure and uncontrolled impacts.
