Solution Overview

Problem

Existing destruction chambers face challenges in providing effective and easily replaceable internal fragmentation and wear protection, especially in cylindrical designs where the openable inlets and outlets are limited, making it difficult to maintain and replace worn parts without compromising the gas-tight outer shell.

Innovation Solution

A method utilizing a large number of identical segments with special locking parts to form a continuous protective layer within the chamber, allowing for easy replacement through the existing aperture, which includes curved beam elements that fit tightly together and are secured by tubular and circular locking parts, providing comprehensive protection against fragments, pressure waves, and heat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a cylindrical destruction chamber with limited openable inlets and outlets is used, then the chamber structure is simplified and gas-tightness is maintained, but replacement of worn internal fragmentation protection becomes difficult and time-consuming

Engineering Contradiction:
Improvechamber structure simplicityVSAvoidreplacement of internal fragmentation protection
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The internal fragmentation protection is divided into multiple identical segments that can be individually removed and replaced through the limited aperture. Each segment is designed to be independently handleable while collectively forming a complete protective layer when assembled together

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The segments are designed with three-dimensional geometry that allows them to be inserted through a two-dimensional aperture smaller than their final assembled dimensions. The segments arrange themselves in a specific spatial configuration (forming a conical surface) that provides comprehensive protection despite the limited access opening

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Reliability

If the inner shell is made replaceable to withstand wear and tear, then the chamber's durability is improved, but the complexity of the chamber structure increases

Engineering Contradiction:
Improvechamber durabilityVSAvoidchamber structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protective function is segmented into multiple identical replaceable segments rather than requiring replacement of a complex integrated inner shell. This allows the protective layer to be renewed without replacing the entire chamber structure

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The segments serve multiple functions: they provide fragmentation protection, absorb pressure waves, and can be easily removed and replaced through the existing aperture. The same segments also form a continuous protective surface when assembled, eliminating the need for separate components

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

AI summary

The present invention relates to a new method for providing a destruction or detonation chamber (1, 9 and 27) intended for the destruction of ammunition products and other explosive products with an easily replaceable internal detonation and fragmentation protection (23-25). A particular characteristic of the detonation and fragmentation protection (23-25) according to the invention is that it comprises a large number of identical segments, which can take the form of a small number of interacting and mutually complementary variants, and which are all characterized in that they are relatively easy to handle and can be delivered to the interior of the destruction chamber (1, 9 and 27), where they are fitted in place through the closeable aperture (29), which in operation of the destruction chamber is used to charge the explosive material that is to be destroyed therein.
