Wearable Tag Location Mapping With Sensor-Based Access Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an efficient method to accurately locate and manage items, such as badges or equipment, within facilities, which hinders facility optimization and emergency response.
Innovation Solution
A system comprising sensors at known locations within a facility, a processor, and tags with unique identifiers that broadcast their location, allowing the processor to determine and record the item's location on a virtual map, and authorize access to equipment based on operator authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a system uses sensors and tags to track items in a facility, then location accuracy and facility management efficiency are improved, but device complexity and system cost increase
Solution Approach 1:
The system employs multi-functional sensors that can detect both presence and location of tags, and the processor performs multiple functions including location determination, zone association, and access authorization. This consolidates multiple functions into integrated components, improving location accuracy while managing system complexity through functional integration rather than separate dedicated components for each function.
2Productivity
If the system tracks and monitors item locations in real-time, then facility optimization and emergency response are improved, but energy consumption and data processing requirements increase
Solution Approach 1:
The system implements periodic location tracking and monitoring rather than continuous real-time monitoring. Sensors periodically detect tag locations and transmit this information to the processor, which then updates zone associations and access authorizations at scheduled intervals. This periodic operation maintains facility optimization capabilities while significantly reducing energy consumption compared to continuous monitoring.
3Reliability
If the system implements access authorization based on operator authentication, then safety and security are improved, but device complexity and operational time increase
Solution Approach 1:
The system performs access authorization checks in advance before allowing operators to access equipment or zones. The processor pre-authenticates operators based on their credentials stored in the database, and pre-associates them with appropriate zones. This preliminary authorization action ensures safety and security while streamlining operational flow, as authenticated operators can move freely within authorized zones without repeated authentication delays.
