Self-loading pistol with detachable shoulder rest and carriage receiving device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pistols lack stability during shooting, leading to potential misses and injuries due to vibration and recoil, and their design often results in material fatigue of sighting devices from high acceleration forces.
Innovation Solution
A pistol design featuring a receiving device that encloses the carriage in its rear end position, a shoulder rest that can be connected via a holding device to stabilize the pistol, and a locking mechanism to secure the shoulder rest, reducing recoil-induced injuries and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the pistol is held freehand for shooting, then the pistol structure remains simple, but the stability during shooting deteriorates leading to potential misses and injuries
Solution Approach 1:
The pistol system is divided into two independent parts: the pistol itself and the shoulder rest. The shoulder rest can be attached when stability is needed and removed when not needed, allowing the pistol structure to remain simple while providing stability on demand.
Solution Approach 2:
The shoulder rest is designed to be dynamically attachable and detachable via a retention device. This dynamic configuration allows the system to adapt between simple handheld operation and stable shoulder-supported shooting based on the situation.
2Productivity
If the slide is allowed to recoil freely during reloading, then the reloading process is simple and quick, but the risk of injury to the user increases
Solution Approach 1:
The receiving device is designed in advance to counteract the harmful recoil motion of the slide. By providing a pre-configured enclosure that guides and limits slide movement, the system prevents injury before it can occur during the reloading process.
Solution Approach 2:
The harmful recoil energy of the slide is converted into a beneficial guiding motion within the receiving device. The slide's backward movement is channeled through the receiving device's structure, transforming the potentially injurious force into a controlled mechanism that ensures safe ejection and reloading.
3Ease of manufacture
If the optical sight is mounted on the moving slide, then the sight positioning is simple, but material fatigue occurs due to high acceleration forces
Solution Approach 1:
The optical sight is extracted from the moving slide and relocated to the stationary frame. This separation removes the sight from the high-acceleration environment of the sliding mechanism, eliminating the cause of material fatigue while keeping the mounting process straightforward.
4Measurement precision
If the pistol is held close to the face for optimal aiming, then the aiming precision is improved, but the risk of face injury from recoil increases
Solution Approach 1:
The shooter's positioning is changed from a direct frontal approach to a lateral positioning where the shoulder rest contacts the shoulder. This dimensional change in body-pistol orientation allows the face to be positioned away from the recoil path while maintaining optimal aiming alignment through the sight.
