Solution Overview

Problem

Conventional explosive detonating systems pose risks to operators due to the need for assembly and transportation of multiple ignition devices and the potential for accidental initiation, as they require specialized devices for each type of shock tube and lack a safe disconnection mechanism, leading to increased danger and logistical burdens.

Innovation Solution

The development of an explosive detonating system with connectable components, including a firing actuator, shock tube adapter, cap box, and priming well, allowing for quick connection and disconnection of the explosive pathway, enabling safe transportation and use of a single firing actuator for multiple systems, and reducing the risk of premature initiation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional explosive systems use multiple specialized ignition devices for different shock tube types, then each specific explosive charge can be initiated, but the device complexity and logistical burden increase significantly

Engineering Contradiction:
Improvecompatibility with different shock tube typesVSAvoidnumber of ignition devices required
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The firing actuator is designed with a universal interface that can accommodate multiple types of shock tubes through a standardized adapter system. The adapter includes a shock tube receiver that can interface with different shock tube configurations, allowing a single firing actuator to initiate various explosive charges regardless of shock tube type, thereby eliminating the need for multiple specialized ignition devices

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

Solution Approach 2:

The ignition system is divided into modular components: a reusable firing actuator, interchangeable adapters, and disposable shock tubes. This segmentation allows the complex firing mechanism to be separated from the shock tube-specific interface, with the adapter serving as a transitional element that enables compatibility without requiring multiple complete ignition devices

Inventive Principle:
Principle #1Segmentation

2Productivity

If the explosive system is assembled and transported in a connected state, then deployment is faster, but the risk of accidental initiation increases

Engineering Contradiction:
Improvedeployment speedVSAvoidrisk of accidental detonation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The explosive system is segmented into separate functional modules that can be transported independently: the firing actuator, the adapter with shock tube, and the explosive charge with blasting caps. These modules can be quickly connected at the deployment location through simple interface mechanisms, enabling fast assembly without requiring the system to be pre-assembled and transported in a connected state, thus maintaining safety while achieving rapid deployment

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter serves as an intermediary component between the firing actuator and the shock tube/explosive charge assembly. This intermediary allows the firing actuator to be disconnected from the explosive pathway during transport, eliminating accidental initiation risk, while enabling quick connection at the deployment location through the adapter's interface mechanisms

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If a single firing actuator is used for multiple explosive charges, then logistics are simplified, but the risk of cross-contamination or premature initiation increases

Engineering Contradiction:
Improvenumber of ignition devicesVSAvoidrisk of premature initiation
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The shock tube and explosive charge assembly is extracted as a separate, disposable unit that connects to the firing actuator only when needed. After initiation, the shock tube consumes the firing impulse and isolates the blasting cap from the firing actuator. This extraction ensures that residual energy or accidental subsequent activations of the firing actuator cannot affect already-initiated or unrelated explosive charges, maintaining reliability while using a single reusable firing actuator

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

An explosive detonating system comprises connectable components to connect/disconnect a pathway that ignites an explosion. A firing actuator activates primers. An adapter connects the firing actuator to shock tube and channels the ignition force from the primers into the shock tube. A cap box houses blasting caps coupled to the end of the shock tube. A priming well is coupled to the cap box/blasting caps and detonating cord. When the firing actuator is initiated, the percussion caps ignite, sending an explosive jet of gas into the shock tube, which ignites an explosive liner. An explosive wave travels through the shock tube and activates the blasting caps, which activate the detonating cord in the priming well. The explosive is placed in a location to provide a desired explosive effect. For example, the system may be employed as a system to breach into structures, remove obstacles and/or barriers, or other applications.
