Solution Overview

Problem

Existing artillery ammunition storage systems on warships and submarines face challenges due to the weight and variety of ammunition types, requiring manual handling and interrupting firing actions for drum reloading, which is dangerous and inefficient, especially during fast-paced battles.

Innovation Solution

A storage system featuring a plurality of rotary drums with a rotatable support and data processing unit for automated selection and loading of different ammunition types, allowing for continuous, high-rate, and automated ammunition supply to artillery pieces, with the ability to reload and unload munitions without interrupting the firing process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual handling devices are used to move ammunition from magazine to artillery piece, then the weight and dimensions of ammunition can be managed, but the operation becomes complex and requires special handling devices

Engineering Contradiction:
Improveease of ammunition handlingVSAvoidcomplexity of handling devices
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The storage system is divided into multiple drums, each capable of holding multiple ammunition rounds. The carousel is segmented into multiple positions, with each position containing a drum. This segmentation allows the system to handle different ammunition types efficiently while maintaining manageable operational complexity through modular design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The storage system is designed to handle multiple types of artillery ammunition (different calibers, lengths, and warhead types) using the same carousel and drum mechanism. The system can store and retrieve various ammunition types through the same automated pathway, reducing the need for specialized handling devices for each ammunition type.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If traditional drum storage is used, then ammunition can be stored and retrieved, but the firing action must be interrupted when the drum is empty requiring manual reloading

Engineering Contradiction:
Improvecontinuous firing rateVSAvoidtime lost during drum reloading
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

Multiple drums are pre-loaded with different ammunition types and positioned on the carousel in advance. When one drum is emptied, the system can quickly switch to another pre-loaded drum without interrupting the firing action. The carousel positions multiple drums so that replacement is already prepared and can be executed rapidly.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The carousel rotates to continuously present loaded drums to the loading position. When a drum is depleted, the system automatically or semi-automatically replaces it with a pre-loaded drum from the carousel, maintaining continuous ammunition supply to the artillery piece without stopping the firing sequence.

Inventive Principle:
Principle #20Continuity of useful action

3Adaptability or versatility

If manual action is required to change ammunition type, then flexibility to handle different munition types is maintained, but the speed and automation of firing actions is reduced

Engineering Contradiction:
Improveability to handle different ammunition typesVSAvoidautomation of ammunition selection
Core Design Contradiction:
Adaptability or versatilityVSExtent of automation

Solution Approach 1:

Different ammunition types are segregated into separate drums, with each drum dedicated to a specific ammunition type. The carousel is segmented into multiple positions, each potentially holding a drum with a different ammunition type. This segmentation allows rapid switching between ammunition types by simply rotating the carousel to a different position, providing both versatility and automation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The carousel provides dynamic reconfiguration of ammunition types at the loading position. By rotating the carousel, the system can quickly switch between different ammunition types stored in different drums, enabling automated adaptation to different firing requirements without manual intervention for each ammunition type change.

Inventive Principle:
Principle #15Dynamics

4Speed

If drums are positioned fixedly for ammunition retrieval, then simple retrieval mechanism is used, but the system cannot quickly switch between different ammunition types during battle

Engineering Contradiction:
Improvespeed of ammunition type switchingVSAvoidcomplexity of drum positioning mechanism
Core Design Contradiction:
SpeedVSDevice complexity

Solution Approach 1:

The carousel merges the functions of multiple fixed storage positions into a single rotating structure. Instead of having separate fixed retrieval mechanisms for each ammunition type, the carousel combines multiple drum positions into one unified system that can present any drum to the loading position by rotation, reducing overall system complexity while increasing switching speed.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The carousel introduces dynamic positioning of drums, allowing the system to rotate and present different ammunition types to the loading position as needed. This dynamic repositioning capability enables rapid switching between ammunition types while using a relatively simple rotating mechanism rather than complex individual positioning systems for each drum.

Inventive Principle:
Principle #15Dynamics
