Holster Detector for Automatic Force Instrument Alarm Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm systems for authorities, such as police and border guards, face challenges in quickly and reliably communicating the removal of a force instrument from a holster to a control room, especially in high-pressure situations where verbal communication is difficult.
Innovation Solution
An alarm system with a detector integrated into the holster that sends a signal to a detector-cpu, which processes and transmits a message via the user's communication device to a base station, allowing for immediate and automatic notification to the control room, including information like 'who', 'what', 'where', and 'when' of the situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an authority uses a means of communication to inform the control room of a situation requiring force instrument use, then information can be transmitted to the control room, but the authority cannot perform other tasks quickly due to the time required for verbal communication
Solution Approach 1:
The system performs preliminary action by automatically detecting force instrument removal and pre-forming the alarm message with all necessary information (authority ID, location, timestamp, instrument type) before the authority needs to communicate. The detector-cpu continuously monitors holster status and has the communication message ready to transmit immediately upon detection, eliminating the time delay of manual verbal reporting.
Solution Approach 2:
The system enables self-service by allowing the alarm system to automatically detect the situation, form the message, and transmit it to the control room without requiring the authority to manually operate the communication device. The detector-cpu autonomously handles message formation and transmission, freeing the authority to focus on the emergency situation.
2Speed
If the alarm system automatically forms and transmits messages upon force instrument removal, then communication speed is improved, but the device complexity increases due to detector-cpu and message formation capabilities
Solution Approach 1:
The detector-cpu is designed with multi-functionality to justify its inclusion: it detects force instrument removal, identifies the specific instrument type, forms complete alarm messages with multiple data elements (authority ID, location, timestamp, instrument type), and controls transmission. This consolidation of multiple functions into a single component achieves fast automatic communication while managing system complexity through functional integration.
3Loss of information
If the system transmits detailed information about the situation to the control room, then the control room can assess the situation precisely, but the message complexity and processing requirements increase
Solution Approach 1:
The alarm message is segmented into distinct, standardized information elements: authority identification, location data, timestamp, force instrument type, and alarm condition. This segmentation allows the detector-cpu to systematically collect and transmit each element separately, making message formation manageable while ensuring complete situation information reaches the control room for precise assessment.
Data Source
AI summary
An alarm system includes a detector arranged in connection with a holster for carrying a force instrument, the detector detecting, if the force instrument is removed from the holster; information on the situation is produced on the basis of the identification and relayed to the user's control room so that a message is relayed to the communication unit of the user of the force instrument, the communication unit relaying the message further to the control room via a base station. The detector is adapted to detect the existence of the force instrument in the holster, its missing from or its movement out of or into the holster. A detector-cpu is adapted to receive a signal or message from the detector and forms at least part of the contents of the message on the basis of the signal or message, the detector-cpu being adapted to control the communication unit to transmit the message.
