Solution Overview

Problem

Current packaging for explosives such as electric, non-electric detonators, and primers does not adequately prevent detonation transfer within or between packages, risking a mass explosion in case of accidental initiation.

Innovation Solution

A packaging system with protective elements featuring central bushings equipped with spacing protrusions and transverse surfaces to create air gaps, shield pressure waves, and prevent splinter movement, ensuring a safe distance between explosive products, using plastic materials with high impact strength and electrostatic conductivity for enhanced safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional packaging is used for explosives, then the package structure is simple, but the resistance to detonation transfer is insufficient

Engineering Contradiction:
Improveresistance to detonation transferVSAvoidpackage structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The packaging system is divided into multiple protective elements, each containing individual explosive products. These protective elements are separated by spacing protrusions that create air gaps, effectively segmenting the explosive contents to prevent detonation transfer while maintaining a manageable overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Air gaps created by spacing protrusions serve as intermediary barriers between explosive products. These air gaps act as mediators that block the propagation of detonation waves and pressure waves, preventing direct contact and energy transfer between adjacent explosives without requiring complex active protection systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If explosive products are placed close together to increase density, then the quantity of explosive per package increases, but the risk of detonation transfer increases

Engineering Contradiction:
Improvequantity of explosive per packageVSAvoiddetonation transfer risk
Core Design Contradiction:
Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The protective elements provide localized protection around each explosive product through their central bushing structure and spacing protrusions. This local quality approach ensures that each explosive is individually protected and spaced, allowing high overall density while maintaining low risk at the local level where detonation transfer would occur.

Inventive Principle:
Principle #3Local quality

3Reliability

If protective elements are added to prevent detonation transfer, then the safety against mass explosion improves, but the device complexity increases

Engineering Contradiction:
Improvesafety against mass explosionVSAvoidprotective element structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The protective element serves multiple functions simultaneously: it contains the explosive product, provides spacing between adjacent explosives, creates air gaps for protection, and maintains structural integrity during transport. This multi-functionality reduces the need for separate protective components, thereby limiting the increase in device complexity while improving safety.

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

4Object-affected harmful factors

If air gaps are created between explosive products, then the propagation of pressure waves is shielded, but the volume occupied by the package increases

Engineering Contradiction:
Improvepressure wave propagationVSAvoidpackage volume
Core Design Contradiction:
Object-affected harmful factorsVSVolume of stationary object

Solution Approach 1:

The spacing protrusions create air gaps in the radial dimension around the central bushing, effectively blocking pressure wave propagation paths without requiring increased axial length. This dimensional approach to spacing allows for compact package volume while maintaining effective separation and protection against detonation transfer.

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

AI summary

The invention deals with a package of explosive products with improved resistance to transmission of detonation where the principle is that the package is designed as a system containing at least one packing unit (10) stored in a protective or transport package (100) where in this system each of the packing units (10) consists of at least two protective elements (1, 2, 3) and at least two explosive products (4) where the explosive products (4) are inserted, at least one at a time, in at least some of the protective elements (1, 2, 3) while the protective elements (1, 2, 3) are designed as central bushings (11, 21, 31) that are equipped on their outer surface with spacing protrusions (12,22,32) that have at least on their outer parts a bend and/or extension (2221, 2222, 3221, 3222) and/or at least one transversal surface (121, 221, 321) to create and/or maintain air gaps around the central bushings (11, 21, 31) of the protective elements (1, 2, 3) in the packing units (10) in this package and at the same time to shield free propagation of pressure and/or to shield the movement of splinters from the central bushing (11,21,31) or between the central bushings (11,21,31) towards the other explosive products (4) stored in this package and/or in its vicinity. Another principle consists in the creation of a single protective element (1, 2) and a collective protective element (3).
