Ammunition Packaging Standoff Device for Tip Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging configurations for 30 mm×173 mm ammunition fail to prevent damage such as bent links and flattened projectile tips during handling and transportation, leading to costly losses and wobbling issues during carriage.
Innovation Solution
A heavy-duty packaging arrangement featuring a stand-off device with a support plate and a restraining plate that holds ammunition rounds upside down, preventing contact with the ground and using recyclable materials to reduce costs and prevent wobbling by adjusting the center of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional packaging configurations are used for ammunition, then the packaging is simpler and lighter, but the rounds suffer damage such as bent links and flattened projectile tips during handling and transportation
Solution Approach 1:
The packaging device is segmented into multiple functional components: a container body, a support structure with multiple support members (one for each round), and a cover assembly. Each support member individually cradles a specific round, providing targeted protection while maintaining overall structural integrity. This segmentation allows the packaging to protect each round independently, preventing damage during rough handling.
Solution Approach 2:
The support members act as intermediary elements between the rounds and the container walls. These support members absorb and distribute impact forces, preventing direct contact between the rounds and potentially damaging surfaces. The support members serve as a protective intermediary layer that maintains round integrity during transportation and handling.
2Reliability
If the ammunition container is made heavy duty to prevent damage, then the protection against rough handling improves, but the container becomes heavier and exhibits wobbling when carried
Solution Approach 1:
The support structure is designed with the cover assembly and support members positioned to create a counterbalancing effect. The center of gravity of the entire packaging system is shifted toward the bottom of the container, which counteracts the tendency for wobbling during carriage. This counterbalancing design allows the use of sufficient protective materials without creating excessive instability during transport.
Solution Approach 2:
The rounds are positioned in an upside-down orientation within the container during the packaging process. This preliminary positioning action ensures that the projectile tips rest on the support members rather than on the container bottom, preventing contact with potentially damaging surfaces and distributing weight more effectively to reduce wobbling.
3Device complexity
If the rounds are stored upright in traditional containers, then the packaging is simpler, but the projectile tips frequently contact the ground and become flattened during handling
Solution Approach 1:
The rounds are stored in an inverted (upside-down) position within the container, with the projectile tips pointing upward and resting on support members. This inversion of the traditional storage orientation prevents the tips from contacting the container bottom or ground during handling. The support members are positioned to cradle each round, ensuring that the vulnerable projectile tips are elevated and protected from impact damage.
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 solution effectively prevents damage and wobbling, ensuring safe storage and carriage of ammunition under rough conditions while being cost-effective and compatible with insensitive munition requirements.
Implementation Method 1
The support plate has at least thirty through holes (of diameter slightly less than the round's maximum diameter) into which rounds of ammunition can be inserted one per hole in an upside down position until they are snugly held from sliding down any further
Implementation Method 2
The height of the standoff device is chosen to insure that the tips of these rounds can never touch the ground
Implementation Method 3
the height of the standoff device will be adjusted to lower the center of gravity of the ammunition to below that of the carrying handles. This prevents wobbling

AI summary
A packaging arrangement for 30 mm×173 mm ammunition rounds. The packaging arrangement has a heavy duty standoff device of defined height, which standoff device mounts a very high strength support plate and a heavy duty restraining plate. The support plate has through holes (of diameter slightly less than the rounds defined maximum diameter) to hold the rounds of in an upside down position and from sliding/moving. The height of the standoff device keeps the rounds from being able to touch the bottom of the metal box. The restraining plate has multiple recessed areas sized to accommodate the back ends of the said rounds. The packaging arrangement is lowered into a metal box with handles for carriage purposes. On top, there are Homosite filler pads, and the box accommodates a top lid.
