Adjustable Multi-Angle Firearm Grip via Hinge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pistol grips on firearms are typically fixed, failing to accommodate individual ergonomic needs, as they do not allow for adjustable angles, which can lead to discomfort and reduced handling efficiency during use.
Innovation Solution
An adjustable multi-angle grip design for firearms, featuring an upper and lower portion with a hinge and an angle adjustment mechanism, such as a ball head screw or cylinder head screw, allowing the angle between the grip and the firearm's barrel axis to be varied, enabling users to customize the grip angle for improved ergonomics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed pistol grip is used, then the structure is simple and reliable, but the adaptability to different user ergonomic needs is poor
Solution Approach 1:
The grip is transformed from a fixed static structure to a dynamic adjustable structure through the introduction of a hinge mechanism and angle adjustment screw. The hinge allows the grip angle to be changed relative to the receiver, and the adjustment screw enables fine-tuning of the grip angle, making the grip adaptable to different user ergonomic needs while maintaining structural simplicity.
Solution Approach 2:
The grip is divided into separate components: an upper portion that attaches to the receiver and a lower portion that forms the actual grip. These segments are connected via a hinge mechanism, allowing independent adjustment of the grip angle without affecting the attachment to the receiver. This segmentation enables adaptability while keeping each component simple.
2Ease of operation
If a fixed grip angle is used, then the manufacturing is simple, but the ease of operation for different users is reduced
Solution Approach 1:
The grip angle adjustment mechanism is designed to be user-adjustable without requiring specialized tools or complex procedures. The adjustment screw can be manually turned by the user to change the grip angle, and the hinge mechanism allows easy repositioning. This self-service capability improves ease of operation while maintaining manufacturing simplicity through the use of standard fasteners and mechanisms.
3Adaptability or versatility
If an adjustable angle mechanism is added, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The grip angle parameter is made variable through the introduction of an adjustment mechanism. The hinge allows change in the angular parameter between the grip and receiver, while the adjustment screw enables fine-tuning of this parameter. This parameter change approach improves adaptability while keeping the mechanism relatively simple by using standard hinge and screw components rather than complex adjustable mechanisms.

AI summary
A device implementable on a firearm includes an adjustable multi-angle grip. The grip includes an upper portion and a lower portion. The upper portion is configured to be coupled to a receiver portion of the firearm. The lower portion is pivotably coupled to the upper portion via a hinge on a front side of the grip such that an angle between a longitudinal axis of the lower portion and a longitudinal axis of a barrel of the firearm is variable.
