Self-Leveling Follower With Extended Tangs For Magazine Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ammunition magazine followers in prior art designs tend to jam due to misalignment caused by the curvature of larger capacity magazines, leading to inconsistent force distribution and potential misfeeds, especially with the last two rounds.
Innovation Solution
A self-leveling follower design with extended front and rear tangs that fit into channels in the magazine casing, combined with grooves on the follower floor and optional features like a slope and spacer for improved force distribution and bolt lock back systems, reduces misalignment and misfeeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the magazine capacity is increased, then the ammunition storage volume is improved, but the follower alignment stability deteriorates due to curvature
Solution Approach 1:
The patent extends the follower tangs in the vertical dimension below the follower floor to engage with channels in the magazine casing. This dimensional extension provides a new degree of freedom for alignment correction, allowing the follower to self-level within the curved magazine body while maintaining horizontal alignment with the ammunition cartridges.
Solution Approach 2:
The follower design incorporates self-leveling capability through the extended tangs that automatically engage with the magazine channels. The system serves itself by using the tang-channel interaction to automatically correct alignment deviations caused by magazine curvature, eliminating the need for manual intervention or additional alignment mechanisms.
2Ease of manufacture
If the follower design is simplified, then the manufacturing ease is improved, but the force distribution consistency deteriorates
Solution Approach 1:
The patent applies local quality by concentrating the alignment and force distribution functions in the extended tang regions rather than requiring complex modifications across the entire follower. The tangs are specifically shaped to fit the magazine channels, providing precise local engagement that ensures consistent force distribution while keeping the rest of the follower design simple and manufacturable.
3Reliability
If the tang length is extended, then the self-leveling capability is improved, but the follower insertion difficulty increases
Solution Approach 1:
The magazine channels are pre-formed during magazine manufacturing to receive the extended follower tangs. This preliminary preparation of the reception structure eliminates the need for complex alignment procedures during follower installation, as the channels guide the tangs into proper position automatically.
