Three-Layer Ammunition Tray with Translating Middle Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ammunition trays lack a secure and adjustable mechanism to hold cartridges of varying sizes, leading to potential wobbling and easy removal during use.
Innovation Solution
A three-layered ammunition block system where the middle layer translates relative to the bottom and top layers, using aligned holes and openings to securely lock cartridges with a three-point contact system, accommodating different cartridge sizes through adjustable geometry and fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-layer ammunition tray is used, then the structure is simple, but the cartridge holding security is insufficient leading to wobbling and easy removal
Solution Approach 1:
The ammunition tray is divided into multiple layers (first layer with openings, second layer with holes, third layer with holes) that can translate relative to each other. Each layer provides a different function: the first layer holds cartridges vertically, the second layer provides lateral support through translating holes, and the third layer secures cartridges from the top. This segmentation resolves the contradiction by distributing the holding security function across multiple simple layers rather than one complex layer.
Solution Approach 2:
The second layer is designed to translate relative to the first and third layers, creating a dynamic locking mechanism. When the second layer translates, its holes move to align with or offset from the openings in the first layer, dynamically adjusting the cartridge holding position. This dynamic element provides secure holding without requiring a completely rigid and complex fixed structure.
2Adaptability or versatility
If fixed geometry trays are used, then manufacturing is simple, but adaptability to different cartridge sizes is limited
Solution Approach 1:
The translateable second layer provides adjustable geometry that adapts to different cartridge sizes. By translating the second layer relative to the first and third layers, the effective hole positions and dimensions change, allowing accommodation of various cartridge calibers and lengths without requiring multiple fixed trays or complex adjustment mechanisms.
Solution Approach 2:
The same three-layer structure serves multiple functions: holding cartridges of different sizes, providing lateral support, securing cartridges from top and bottom, and allowing easy loading/unloading. The translateable mechanism universally accommodates various cartridge configurations without requiring different tray designs, resolving the contradiction between versatility and complexity.
3Stability of the object's composition
If cartridges are held loosely, then loading and unloading is easy, but cartridge stability is poor causing wobbling during use
Solution Approach 1:
The translateable second layer creates a dynamic locking system where cartridges are held loosely during loading (when layers are offset) and securely locked during use (when layers translate to aligned positions). The ease of loading is maintained because cartridges can be inserted when the structure is in the open position, while stability is achieved when the second layer translates to lock the cartridges in place.
Solution Approach 2:
The first layer provides preliminary cartridge support and positioning before the second layer translates to lock them in place. The openings in the first layer guide cartridges into the correct vertical position, and then the translating second layer completes the securing action. This preliminary action sequence maintains ease of operation while achieving final stability.
