RFID-Enabled Marking Tool for Underground Facility Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current marking systems for underground facilities require manual switching of paint canisters for different types of facilities, which is inefficient and prone to errors, as they lack automated identification and tracking of marker characteristics during the marking process.
Innovation Solution
A marking tool equipped with a processor, marker dispenser, and tag reader that automatically identifies and stores the characteristics of markers, allowing for precise dispensing and tracking of markers based on tags attached to the marker containers, ensuring correct marking and inventory management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual switching of paint canisters is used for different facility types, then the marking process can be performed with simple equipment, but the operation becomes inefficient and error-prone
Solution Approach 1:
The system uses RFID tags attached to paint canisters that automatically identify the marker type when read by the marking tool. The processor automatically selects and dispenses the correct marker based on the RFID identification, eliminating the need for manual canister switching while maintaining relatively simple equipment structure.
Solution Approach 2:
The manual mechanical action of switching paint canisters is replaced by an automated electronic identification system using RFID tags and readers. The system automatically identifies the required marker and triggers dispensing through electronic control rather than manual intervention.
2Reliability
If automated marker identification is implemented, then marking accuracy improves, but the device complexity increases
Solution Approach 1:
Manual identification of marker characteristics is replaced by automated RFID reading. The marking tool includes an RFID reader that automatically detects the tag on the paint canister, and the processor automatically determines the marker characteristics and triggers appropriate dispensing, significantly improving accuracy with minimal added complexity.
3Loss of time
If manual tracking of marker usage is performed, then inventory management can be simple, but time consumption increases
Solution Approach 1:
The system automatically tracks marker usage by reading RFID tags and recording dispensing events. The processor maintains inventory records and can provide feedback on marker consumption, enabling automated inventory management that reduces time expenditure while adding minimal system complexity.

AI summary
A marking tool and a method for marking a presence or an absence of at least one underground facility is presented. The method includes dispensing a marker when a trigger of a marking tool is actuated. The method further includes identifying at least one characteristic associated with the marker or the dispensing of the marker. The method further includes storing the at least one characteristic associated with dispensing the marker when the actuation of the trigger is signaled.
