Modular Wireless Detonator Initiating Assembly for Safe Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless detonator initiating arrangements are bulky, require electrical power for operation, and pose challenges in safe assembly and transport due to the integration of hazardous components.
Innovation Solution
A modular wireless detonator initiating arrangement comprising separate modules for signal processing, explosive material, and an initiator, allowing safe storage and transport by separating hazardous components until assembly on-site, with power supply integration only when needed, and using wireless communication through rock or a top-box for control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If components are integrated into a single unit, then the device is easier to operate, but it becomes bulky and difficult to transport safely
Solution Approach 1:
The initiating arrangement is divided into separate modules: a first module containing the signal processing assembly and housing, a second module containing the explosive material and booster, and a third module containing the power supply. These modules can be transported separately and assembled on-site, reducing bulkiness during transport while maintaining operational ease when assembled.
2Object-affected harmful factors
If hazardous components are separated from non-hazardous components, then transport and storage safety is improved, but assembly complexity increases
Solution Approach 1:
The system is segmented into hazardous modules (explosive material, booster, initiator) and non-hazardous modules (signal processing assembly, power supply). Each module can be transported and stored separately according to its hazard classification, improving safety during logistics while the modular design actually simplifies assembly by allowing standardized connections on-site.
3Ease of operation
If power supply is always connected, then the device is ready for operation, but it increases bulkiness and safety risks during transport
Solution Approach 1:
The power supply is separated into its own third module that can be connected to the first module only when needed for operation. This allows the signal processing assembly to be transported without the power supply, reducing bulkiness and safety risks during transport, while ensuring the system is ready for operation when the power supply module is connected on-site.
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
Facilitates safe and efficient assembly on-site by ensuring components are only connected when required, reducing bulkiness and adhering to hazardous material regulations, while enabling reliable wireless operation.
Implementation Method 1
The signal processing assembly, responsive to a wireless fire command signal from a blast controller, is used to cause ignition of the initiator
