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 manual tracking methods are used for items and operators in a facility, then system complexity is reduced, but location accuracy and real-time monitoring capability deteriorate
Solution Approach 1:
The system uses universal RFID tags that can identify multiple types of objects (operators, equipment, items) with a single technology platform. The sensors are multi-functional, detecting both presence and location information. This universal approach achieves precise tracking of diverse facility elements without requiring separate complex systems for each tracking need.
Solution Approach 2:
The patent introduces RFID tags as intermediary carriers of identification information and sensors as intermediary detection devices. These intermediaries enable automatic, precise location tracking without requiring direct human intervention or complex manual procedures, thereby improving measurement precision while keeping the overall system manageable through standardized intermediary components.
2Loss of time
If no automated location tracking system is implemented, then device complexity is reduced, but response time for emergency and maintenance dispatch deteriorates
Solution Approach 1:
The system performs preliminary actions by continuously and automatically tracking the locations of operators, equipment, and items before emergencies or maintenance needs arise. This real-time location awareness is established in advance, enabling immediate dispatch responses when events occur, thereby reducing response time without requiring complex ad-hoc location determination procedures.
Solution Approach 2:
The system implements continuous feedback loops where sensors constantly detect tag locations and transmit this information to the central processor. This real-time feedback mechanism ensures that location data is always current, enabling rapid response to emergencies and maintenance needs while automating the information flow to reduce manual intervention complexity.
3Productivity
If real-time location tracking of all items and operators is implemented, then facility management efficiency is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic action by having RFID tags broadcast their identification information at predetermined intervals rather than continuously. This periodic broadcasting reduces energy consumption compared to continuous transmission while still providing sufficient location data for effective facility management. The sensors periodically detect these broadcasts and update location information accordingly.
