Firearm Stabilizing Brace Assembly with Optical Sight Chassis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pistols lack stability and accuracy due to their design, making it difficult to attach and switch optical sights, which are advantageous for improved aiming in various conditions.
Innovation Solution
A shoulder stock assembly that includes a stabilizing brace and a chassis configured to attach to a pistol, allowing for additional stability and the positioning of optical sights, with various attachment methods such as fastening pins and clamping arrangements to accommodate different pistol designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a shoulder stock is attached to a pistol, then stability and accuracy are improved, but device complexity increases
Solution Approach 1:
The stabilizing brace assembly is divided into separate modular components including a chassis, stabilizing brace, backstrap assembly, and multiple attachment mechanisms. This segmentation allows the complex functionality to be achieved through independent parts that can be assembled and disassembled, managing overall device complexity while providing rifle-like stability to the pistol
Solution Approach 2:
The chassis serves multiple functions simultaneously: it provides a mounting platform for optical sights, serves as an attachment point for the stabilizing brace, and includes integrated clamp arms for securing to the pistol frame. This multi-functionality reduces the need for separate components, managing device complexity while achieving stability
2Measurement precision
If an optical sight is mounted on the pistol slide, then aiming accuracy is improved, but ease of operation deteriorates due to permanent modification requirements
Solution Approach 1:
The chassis acts as an intermediary between the pistol and the optical sight, providing a removable mounting platform. This intermediary allows the optical sight to be mounted without permanently modifying the pistol slide, enabling easy switching between different sight configurations while maintaining aiming accuracy
Solution Approach 2:
The optical sight mounting is designed to be dynamic and adjustable rather than fixed. The mounting platform on the chassis can be repositioned and reconfigured, allowing the user to adjust the sight position and easily switch between different optical sights without permanent modifications to the pistol
3Reliability
If multiple attachment points are added to the chassis, then reliability of attachment is improved, but device complexity increases
Solution Approach 1:
Multiple attachment functions are merged into integrated components. The clamp arms combine clamping functionality with mounting provisions, the fastening pin integrates multiple securing points, and the backstrap assembly combines with the chassis structure. This merging achieves reliable multi-point attachment while managing complexity through integrated design

AI summary
Implementations of a stabilizing brace assembly for a firearm are provided. The stabilizing brace assembly is configured for use in attaching a forearm stabilizing brace to a pistol, thereby providing additional stability to a user aiming and firing the pistol. In some implementations, the stabilizing brace assembly is also configured to position an optical sight (e.g., a reflex type sight) so that it can be used to aim the pistol.
