Single-shot Rifle Butt-Plate Dynamics for Compact Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing single-shot rifles face challenges in achieving optimal transportability while maintaining lightness, easy assembly, and use, as they often compromise on size and comfort during transport due to their design.
Innovation Solution
The design incorporates a butt-plate that can be manually moved between a use position for comfortable shooting and a rest position to minimize dimensions, along with a detachable barrel unit and a transport assembly that allows the rifle to be stored in a compact, watertight casing for easy carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rifle is designed with a fixed butt-plate for comfortable shooting, then shooting comfort is improved, but transport dimensions increase
Solution Approach 1:
The butt-plate is designed to be movable rather than fixed, allowing it to rotate between a use position for comfortable shooting and a rest position for compact transport. This dynamic configuration enables the rifle to adapt its structure based on operational needs, resolving the contradiction between shooting comfort and transport dimensions.
Solution Approach 2:
The butt-plate is separated from the main rifle body as an independent component that can be repositioned. This segmentation allows the butt-plate to be moved to different positions (use position or rest position) without affecting the integrity of the main rifle structure, enabling compact transport while maintaining shooting comfort.
2Strength
If the rifle components are permanently assembled for structural integrity, then strength is improved, but assembly ease deteriorates
Solution Approach 1:
The rifle is divided into separable components (barrel unit, butt-box unit, butt-plate) that can be independently manufactured and assembled. This segmentation maintains structural integrity of each component while enabling easy assembly and disassembly of the complete rifle system.
Solution Approach 2:
The coupling means are pre-configured with alignment features and engagement mechanisms that guide the assembly process. The barrel unit and butt-box unit include predetermined coupling interfaces that ensure proper alignment and secure connection during assembly, maintaining structural integrity while simplifying the assembly process.
3Ease of operation
If the rifle is designed with extended features for comfortable use, then ease of operation is improved, but transportability worsens
Solution Approach 1:
The rifle incorporates movable components (butt-plate, detachable barrel unit) that can be repositioned or removed based on transport needs. During use, these components are positioned for optimal ergonomics and operation; during transport, they are moved to minimize the rifle's dimensions, achieving adaptability between operational and transport states.
Solution Approach 2:
The rifle is segmented into modular units that can be independently positioned or removed. The butt-plate can be moved to a rest position or detached, and the barrel unit can be separated from the butt-box unit, allowing the rifle to be configured for compact transport while maintaining full functionality during use.

AI summary
A single-shot rifle having a barrel unit and a butt-box unit consisting of a box, a butt having a butt axis, fixed to the box, and a butt-plate fixable to the butt is provided. The barrel unit is detachable from the butt-box unit. The butt-plate is manually rotatable between a use position and a rest position and the barrel unit is laterally couplable to the butt-box unit. The single-shot rifle with separate parts is insertable into a substantially rigid tube for carrying the weapon. The tube and the single-shot rifle housed in the tube form a floating, waterproof assembly.
