Pivoting-Arm Primer Magazine Changer for Automated Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weapon systems require manual intervention to replace primer magazines, which are cumbersome and inefficient, especially in modern systems where automatic loading of projectiles and propellant charges is implemented.
Innovation Solution
A primer magazine changing device with a pivotable holding device that allows for reliable movement and transfer of primer magazines between a depot and a weapon's magazine slot, utilizing a pivot arm and holding device design that ensures secure, uniaxial movement and alignment, with features like guides, retaining pads, and a gripping device for automated operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual intervention is used to replace primer magazines, then the structure remains simple, but productivity and automation level deteriorate
Solution Approach 1:
The holding device is made pivotable about a pivot axis, allowing it to dynamically change position between the primer magazine depot and the weapon's magazine slot. This dynamic capability enables automated transfer without manual intervention, resolving the contradiction between automation and simplicity by using controlled mechanical movement rather than complex multi-axis mechanisms
Solution Approach 2:
The holding device serves multiple functions: it holds the primer magazine, transfers it between locations, and interfaces with both the depot and weapon systems. This multi-functionality reduces the need for separate specialized components, achieving automation while maintaining relatively simple device structure
2Productivity
If a pivotable holding device is used for automated transfer, then productivity and automation improve, but device complexity increases
Solution Approach 1:
The magazine changing system is segmented into distinct functional components: the pivot arm for positioning, the holding device for securing the magazine, the depot for storage, and the weapon interface. This segmentation allows each component to be optimized independently, achieving fast automated replacement without requiring the entire system to be overly complex
Solution Approach 2:
The holding device acts as an intermediary between the depot and the weapon, transferring the primer magazine between these two locations. This intermediary approach enables automated high-speed replacement by decoupling the storage and firing systems, allowing each to operate independently while maintaining simple individual structures
3Reliability
If the holding device is rigidly fixed, then structural simplicity is maintained, but adaptability and reliability of transfer deteriorate
Solution Approach 1:
The holding device incorporates a pivot mechanism that allows it to rotate about a pivot axis, dynamically adjusting its position to reliably interface with both the depot and weapon magazine slots. This dynamic positioning ensures reliable transfer regardless of slight variations in alignment, achieving high reliability without requiring complex active control systems
Solution Approach 2:
The pivotable holding device changes its angular parameter (rotation angle) to adapt between different transfer positions. This parameter change enables the device to reliably accommodate variations in positioning while maintaining a simple mechanical structure without sensors or active control, resolving the contradiction between reliability and complexity
