Ammunition Magazine Loader Pivot Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ammunition magazine loaders are inefficient in accommodating different magazine lengths and do not effectively manage stress on rounds during loading, leading to potential misalignment and incomplete loading.
Innovation Solution
An ammunition magazine loader with a main body, rounds recess, and magazine recess, featuring a rounds abutment and optional retention recess, designed to accommodate various magazine lengths and securely position rounds for efficient loading by using a pivot mechanism to angle case ends and facilitate entry into the magazine.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the magazine recess is designed to accommodate the full length of the magazine, then the magazine can be securely retained, but the device complexity increases and the main body length increases
Solution Approach 1:
The magazine retention function is segmented from the main body structure. The magazine recess is designed to accommodate only a portion of the magazine length, with the remaining magazine extending beyond the recess. This is achieved through a magazine retention protrusion that extends from the main body into the magazine recess, creating a segmented retention mechanism that reduces overall device complexity while maintaining reliable magazine retention.
2Reliability
If the rounds recess is designed with fixed positioning structures, then the rounds can be securely held, but the adaptability to different magazine lengths decreases
Solution Approach 1:
The rounds recess incorporates a movable rounds abutment that can dynamically adjust its position along the rounds recess length. This movable abutment maintains reliable round positioning while adapting to different magazine lengths, as it can be positioned at different locations along the recess to accommodate varying magazine configurations without compromising round retention reliability.
3Manufacturing precision
If the loader uses a pivot mechanism to angle case ends, then the loading accuracy improves, but the device complexity increases
Solution Approach 1:
The pivot mechanism uses a rounds abutment as an intermediary element that facilitates the angling of case ends during loading. The abutment acts as a mediator between the round and the magazine, providing a pivot point that enables precise alignment of case ends with the magazine opening. This intermediary approach achieves high loading accuracy while keeping the overall device complexity manageable by using a simple abutment structure rather than a complex mechanical pivot system.
4Length of moving object
If the magazine recess length is reduced, then the main body length decreases, but the ability to accommodate different magazine lengths decreases
Solution Approach 1:
The magazine recess is designed with dynamic adaptability through a movable magazine retention protrusion that can adjust its position along the recess length. This allows the recess to accommodate magazines of varying lengths while maintaining a compact main body. The protrusion can be positioned at different locations to match different magazine lengths, enabling the device to maintain short main body length without sacrificing adaptability to various magazine sizes.

AI summary
An ammunition magazine loader include a main body, a rounds recess, a rounds abutment, and a magazine recess. Rounds are provided to the rounds recess and positionally maintained by a rounds recess bottom and first and second rounds recess ledges. With a magazine positioned within the magazine recess and rounds within the rounds recess, as the rounds are slidably moved out of the rounds recess, each round abuts the rounds abutment and pivots to orient the round such that its second case end is angled towards the magazine recess.
