Adjustable Swivel Cheek Piece Buttstock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small arms buttstock designs are overly complex and unreliable due to their numerous parts, which limits their ability to effectively adjust to individual anthropometric characteristics for improved shooting comfort and quick aiming transitions.
Innovation Solution
A simplified buttstock design featuring a spring-loaded link interacting with a trigger button, a torsion spring, and an axle that directly transfers energy to a swivel platform, reducing parts and enhancing reliability, with a removable and adjustable cheek piece that can rotate and lock into offset positions for customizable fit and quick aiming adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a complex mechanism with multiple parts (driven gear, driving pinion, spring-loaded link) is used to adjust cheek piece position, then the cheek piece can be quickly repositioned, but the reliability decreases due to more parts
Solution Approach 1:
The patent removes the driven gear and driving pinion from the mechanism, extracting only the essential spring-loaded link that directly interacts with the trigger button. This elimination of unnecessary parts maintains the quick repositioning capability while significantly improving reliability by reducing the number of components that could fail.
Solution Approach 2:
The patent combines the functions of multiple separate components (driven gear, driving pinion, and spring-loaded link) into a single integrated spring-loaded link mechanism. This merging reduces part count and complexity while maintaining the functional capability of quick cheek piece adjustment through direct interaction with the trigger button.
2Adaptability or versatility
If multiple components (driven gear, driving pinion, spring-loaded link) are used to transfer spring energy, then the cheek piece can be adjusted, but the design complexity increases
Solution Approach 1:
The patent extracts and removes the driven gear and driving pinion components, keeping only the essential spring-loaded link. This extraction maintains the cheek piece adjustability function while dramatically reducing design complexity by eliminating unnecessary intermediate components in the energy transfer path.
Solution Approach 2:
The patent merges the energy transfer function directly from the spring-loaded link to the swivel platform, eliminating the need for separate gear mechanisms. This consolidation reduces design complexity while preserving the full adjustability capability through direct mechanical coupling.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution significantly reduces the complexity and enhances the reliability of the buttstock mechanism, allowing for precise adjustments to fit different shooters and enable quick transitions between primary and sector sights without compromising reliability.
Implementation Method 1
a torsion spring; the buttstock is additionally fitted with an axle which is attached to one end of the torsion spring, while its other end is fixed to the swivel platform
Data Source
AI summary
There is an axle (2) installed in the buttstock body. One end of the axle (2) is connected to the first end of the spring and the second end of the spring is fixed to the swivel platform. The swivel platform is being centered by means of one axle, the spring energy is transferred directly from the axle to the swivel platform. This makes possible to simplify the trigger mechanism of the swivel platform rotation and to increase the performance reliability.
