Explosive Device Ignition Control via GPS Position Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing explosive or incendiary devices do not adequately prevent improper use, as they lack robust mechanisms for ensuring that only authorized personnel can activate or deactivate these devices under defined conditions, particularly concerning geographical and temporal parameters.
Innovation Solution
The method employs an ultrasonic, low-frequency, and/or high-frequency receiver integrated into the primer of the device, coupled with a unit providing an electrical ignition pulse, which uses GPS, Glonass, or similar satellite-based systems for position determination and a special interface to block or enable the ignition command based on predefined territories and time controls, ensuring secure activation only within authorized areas and times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods for securing explosive devices are used, then the devices can be activated or deactivated, but they lack robust mechanisms to prevent improper use by unauthorized personnel
Solution Approach 1:
The patent introduces an intermediary control system that acts as a mediator between the explosive device and the user. This control system includes a receiver that communicates with a control unit, which verifies authorization credentials and geographical conditions before allowing activation. The intermediary layer ensures that only authorized personnel can activate the device under defined conditions, thereby improving reliability without directly modifying the explosive mechanism itself.
Solution Approach 2:
The patent implements preliminary verification of authorization credentials and geographical location before the explosive device can be activated. The control unit checks the user's authorization status and the device's current location against predefined safe zones in advance. This preliminary action prevents improper use by ensuring all safety conditions are met before activation is permitted, enhancing reliability through proactive safety checks.
2Reliability
If authorization verification and geographical control mechanisms are added, then improper use is prevented, but the device complexity increases
Solution Approach 1:
The control unit is designed to perform multiple functions: verifying authorization credentials, determining geographical location via GPS receiver, comparing location against safe zones, and controlling the ignition pulse. By consolidating these diverse functions into a single multi-functional control unit, the patent prevents improper use through comprehensive verification while minimizing the increase in device complexity through functional integration.
Solution Approach 2:
The patent replaces manual verification mechanisms with electronic and satellite-based systems. Instead of physical keys or manual authorization processes, the system uses electronic credential verification and GPS-based geographical control. This substitution reduces the need for complex mechanical control components while maintaining robust prevention of improper use through automated verification systems.
3Reliability
If continuous monitoring and tracking systems are implemented, then authorized use under defined conditions is ensured, but energy consumption increases
Solution Approach 1:
The control unit performs verification and monitoring at periodic intervals rather than continuously. The system checks authorization credentials when activation is requested and verifies geographical location at relevant moments during operation. This periodic action ensures continuous safety monitoring is maintained while reducing energy consumption compared to truly continuous monitoring, as the system activates monitoring only when needed for safety verification.
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
This solution significantly enhances safety by ensuring that explosive or incendiary devices can only be used by authorized persons under defined conditions, preventing accidental or unlawful use by maintaining the detonator in a blocked state outside authorized zones and times, with continuous monitoring and tracking of events.

Data Source
AI summary
The invention relates to a method for controlled automatic activation or deactivation of explosive devices comprising at least one ignition capsule, contained in the explosive device, which capsule can be triggered electrically, wherein an e.g. high-frequency receiver and a unit for providing an electrical ignition pulse are provided on or in the ignition capsule body. According to the invention, the unit for providing the electrical ignition pulse has an interface in order to enable or disable a triggering of the ignition capsule in accordance with a position signal, wherein the enabling or disabling takes precedence over an ignition command received by the high-frequency receiver. Furthermore, the position signal is provided by a receiving apparatus which allows position determination by means of GPS, GLONASS or similar satellite-based systems, wherein triggering of the ignition capsule is always or always remains disabled until a predetermined territory is reached or returned to.
