RFID Tool Tracking with Automated Process Log Association
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for tracking tools in operation rooms and similar environments are inefficient, requiring extensive manual counting and record-keeping, leading to potential errors and increased risks, as well as challenges in managing the life cycle of tools, including maintenance and sterilization.
Innovation Solution
A computerized system that uses RFID tags to uniquely identify tools and associates process logs with the tools, where tag readers record the identity and location of tools during processing, and transmit this information to a server for automated tracking and record-keeping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual counting and tracking of tools is performed, then tool location and maintenance records can be obtained, but extensive personnel time, mental resources, and down-time are required leading to inefficiency and errors
Solution Approach 1:
The patent replaces manual mechanical counting and tracking processes with an automated electronic system using RFID tags, tag readers, and a server-based tracking program. This substitution eliminates the need for personnel to manually count and record tool locations, thereby improving operational efficiency while maintaining or enhancing tracking accuracy through automated data collection and processing.
Solution Approach 2:
The tracking system operates autonomously by automatically detecting tools via RFID tags, recording their locations, and updating maintenance records without requiring human intervention. The system serves itself by continuously monitoring tool movement and maintaining accurate records, thereby eliminating the need for dedicated personnel time and mental resources while improving both efficiency and reliability.
2Object-affected harmful factors
If careful counting is performed before, during and after operation to ensure no tool remains inside patient, then patient safety is improved, but the time the patient's body is open increases with associated risks
Solution Approach 1:
The system performs preliminary tracking and counting actions automatically throughout the surgical process rather than requiring post-operative counting. RFID tags continuously monitor tool locations, and the system can alert surgeons if tools are misplaced, allowing immediate correction without extending surgical time or compromising patient safety.
Solution Approach 2:
The tracking system provides real-time feedback on tool locations during surgery through the server and interface. This immediate feedback allows surgical teams to verify tool accountability without delaying the procedure, maintaining patient safety while minimizing the time the patient's body remains open.
3Ease of operation
If process logs are not associated with specific tools, then processing machines can operate independently, but manual updates are required to keep tool life-cycle information up to date
Solution Approach 1:
The patent merges the process log data from processing machines with tool identification data from RFID tags by associating them through the server. This combination allows the system to automatically link processing information with specific tools, eliminating the need for separate manual record-keeping while maintaining processing independence. The server integrates data from multiple sources to create a unified tool life-cycle record.
Solution Approach 2:
The server acts as an intermediary that receives process logs from processing machines and tool identification information from RFID tag readers. It automatically associates these data streams and updates tool records, thereby eliminating manual intervention while preserving the operational independence of processing machines. The intermediary enables automated data integration without requiring changes to the processing machines themselves.

Data Source
AI summary
A system for associating processed items with process logs, including a server computer for tracking the items and a tag reader positioned in the vicinity of a device for processing the items; wherein the items are marked with a tag that is readable with a tag reader; wherein the device produces a process log listing a commencement time of the process, a type of process performed and an indication if the process completed successfully; wherein the tag reader records identity information of the items inserted and/or removed from the device for processing; and wherein the process log and identity information are provided to the server computer to associate the processes recorded in the process log with the processed items to form tracking information for an item.
