Adjustable Firearm Butt With Micrometric Screw Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearms, particularly guns, suffer from reduced firing accuracy due to recoil and soaring forces, which are not efficiently absorbed by statically connected butts, limiting adaptability to different users' morphological and holding characteristics, and are costly to manufacture and adapt.
Innovation Solution
A firearm butt with adjustable coupling means between the main support structure and butt plate, allowing variable positioning along the longitudinal axis, facilitated by a male tubular element and female housing with a bushing for sliding and compression mechanisms, enabling continuous adjustment and rotation for precise fit to various users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a butt is statically connected to the firearm with fixed components, then the structure is simple and robust, but it cannot adapt to different users' morphological and holding characteristics
Solution Approach 1:
The butt is divided into separate components: a main support structure, a butt plate, and adjustable coupling means. This segmentation allows each component to be optimized independently and enables adjustment of the relative positions to accommodate different users, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The coupling means incorporate adjustable elements that allow the butt plate's position relative to the main support structure to be modified. This dynamic capability enables the butt to adapt to different users while maintaining a relatively simple overall structure when in a fixed state.
2Adaptability or versatility
If a butt is manually adapted for a specific user by expert artisans, then it achieves precise fit, but the costs are considerable and it cannot be used by multiple users
Solution Approach 1:
The butt design with adjustable coupling means creates a universal component that can serve multiple users with different morphological characteristics. The standard main support structure and butt plate can be manufactured once, and the adjustment mechanism allows a single unit to fit multiple users, eliminating the need for custom craftsmanship for each user.
Solution Approach 2:
The adjustable coupling means enable the butt to be modified for different users without requiring manual adaptation by experts. The adjustment mechanism provides a simple, repeatable process that maintains precision while reducing cost and enabling multi-user functionality.
3Productivity
If the butt components are statically associated, then the manufacturing is simpler, but the adaptation to different users is slow and complex
Solution Approach 1:
The coupling means are designed with adjustable elements that allow quick modification of the butt plate position relative to the main support structure. This dynamic capability enables rapid adaptation to different users while keeping the coupling mechanism relatively simple and manufacturable.

AI summary
A butt (1) for a firearm (100, 101) comprising a main support structure (2) suitable to be integrally associated to the barrel (102) and to the firing mechanism (103) of the firearm (100, 101), a butt plate (3) and means (4) for coupling the main support structure (2) to the butt plate (3). Such coupling means (4) are adjustable so as to allow varying the position of the butt plate (3) with respect to the main support structure (2) along the direction defined by the longitudinal development axis of the butt (1). Such coupling means (4) comprise a male tubular element (5) and a body (6) wherein there is provided a female housing (7) with substantially longitudinal development and provided with an inlet opening (71) and a bottom (72). The female housing (7) is slidably receiving the male tubular element (5). The body (6) comprises a through hole (13) defined at the bottom (72) according to a development direction substantially parallel to the development axis of the female housing (7), so that the hole can receive a micrometric screw (14) suitable to be manoeuvred along the female housing (7) so as to define an end stop element to limit the movement of the male tubular element (5) inside the female housing (7).
