Magazine Retention Device With Biasing Side Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ammunition magazine retention devices either obstruct quick access due to flap mechanisms or lack security, leading to potential loss of ammunition during transfer, and often require multiple motions, which can be critical in combat situations, and lack universality in accommodating different sizes and shapes.
Innovation Solution
A pocket design with opposing side panels of varying heights and biasing means, such as elastic bungee or spring-action, that applies constant frictional force while allowing easy extraction of magazines without catching exposed rounds, ensuring secure retention and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flap mechanism is used to secure the magazine in the pouch, then the magazine is retained securely, but the user access speed decreases due to multiple motions required to open the flap
Solution Approach 1:
The patent removes the flap mechanism entirely from the pouch design, extracting the obstructive element that required multiple motions to open. Instead, a retention strap system is used that can be quickly released without the need to manipulate a flap, thereby maintaining security while dramatically improving access speed.
Solution Approach 2:
Instead of using a flap that covers and obstructs the magazine opening (traditional approach), the invention uses a retention strap system that secures the magazine from the sides or bottom, inverting the traditional securing mechanism. This allows the magazine to be accessed by simply releasing the strap rather than manipulating a flap.
2Ease of operation
If a tight-fitting pouch without flap mechanism is used, then access speed improves, but the magazine becomes insecure and vulnerable to ejectment
Solution Approach 1:
The retention strap is pre-configured to engage with the pouch structure before the magazine is even inserted. This preliminary setup ensures that as soon as the magazine is placed in the pouch, it is automatically secured by the strap system, providing immediate retention without requiring any additional securing actions.
Solution Approach 2:
The retention strap acts as an intermediary element between the pouch and the magazine. Rather than relying on the pouch material alone to secure the magazine through friction, the strap provides a dedicated securing mechanism that mediates between the pouch structure and the magazine, ensuring reliable retention while maintaining quick access.
3Reliability
If the pouch is tailored to fit a specific magazine size, then retention security improves, but universality decreases requiring multiple pouch types
Solution Approach 1:
The retention strap system is designed with adjustable features and universal attachment points that can accommodate magazines of various sizes and shapes. The strap length and positioning can be adjusted to fit different magazine dimensions, allowing a single pouch design to securely retain multiple types of magazines rather than requiring specialized pouches for each magazine size.
Solution Approach 2:
The retention strap incorporates dynamic adjustment capabilities, allowing the user to modify the strap tension and positioning based on the specific magazine being stored. This dynamic adaptability enables the same pouch structure to provide optimal retention for different magazine sizes and shapes, enhancing versatility without compromising security.
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 design provides secure and efficient retention of ammunition magazines of varying sizes and shapes, preventing loss during transfer by allowing lateral extraction and maintaining frictional force against the magazine's exterior, thus enhancing usability and safety in combat scenarios.
