Quick Detach Mount Force Distribution and Dual-Lock Stock Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm stock designs face issues such as manufacturing tolerance variance, reduced reliability due to translational movement requirements, complexity in use, and early failure of quick detach mechanisms, along with cumbersome length of pull adjustments and potential breakage during improper folding or cheek riser interaction.
Innovation Solution
A stock assembly with a quick detach mount that distributes carry forces using multiple fasteners, a hinge limiting translational movement, a dual-lock mechanism for safe folding and unfolding, and an adjustable length of pull mechanism that eliminates the need for a third hand, enhancing reliability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single lock mechanism is used for both folded and unfolded configurations, then the device complexity is reduced, but the reliability is compromised and the ease of operation is limited
Solution Approach 1:
The locking mechanism is segmented into two distinct locks: a first lock for maintaining the unfolded configuration and a second lock for maintaining the folded configuration. This segmentation allows each lock to be optimized for its specific function, improving reliability while maintaining operational simplicity.
2Device complexity
If a folding stock assembly requires translation along an axis during rotation, then the folding mechanism can be simpler, but the reliability is reduced and ease of operation is worsened
Solution Approach 1:
The hinge is designed to constrain the folding stock assembly to pure rotation about the hinge axis without translation. This dynamic constraint ensures reliable operation by preventing unintended movement paths while maintaining a relatively simple folding mechanism structure.
3Device complexity
If a quick detach mechanism concentrates forces at a single point, then the device complexity is reduced, but the reliability is compromised due to early failure
Solution Approach 1:
The quick detach mechanism is segmented into multiple force distribution points rather than concentrating force at a single point. This segmentation disperses the mechanical stress across multiple locations, preventing early failure and improving the overall durability of the attachment system.
4Measurement precision
If length of pull adjustment requires a third hand operation, then the adjustment precision can be higher, but the ease of operation is significantly reduced
Solution Approach 1:
The length of pull adjustment mechanism is designed to be self-operating with one hand. The user can adjust the length by manipulating a single component that automatically maintains the selected position, eliminating the need for a second person to hold the stock while achieving precise adjustment.
5Adaptability or versatility
If manufacturing tolerances vary across different manufacturers and countries, then the adaptability of the firearm system increases, but the manufacturing precision of individual components decreases
Solution Approach 1:
The stock and firearm interface is designed with universal compatibility features that accommodate variations in manufacturing tolerances across different manufacturers and countries. The interface geometry and adjustment mechanisms are engineered to function correctly across a range of dimensional variations, ensuring broad compatibility without requiring extremely tight manufacturing precision.
