Guided Lock-Tag-Try Tracking for Safer Maintenance Compliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The Lockout/Tagout (LTT) process in industrial settings is prone to human error and non-compliance, and lacks a practical method for tracking and recording, posing safety risks for technicians performing maintenance on industrial machinery.
Innovation Solution
A system comprising indicators affixed to machinery components, a user device, and a server that scans these indicators to guide users through the LTT process, providing step-by-step instructions and tracking notifications to ensure proper execution and safety protocols are followed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the Lockout/Tagout process is implemented by humans following detailed procedures, then the safety protocols can be established, but human error and non-compliance occur leading to safety risks
Solution Approach 1:
The system enables self-service by allowing the machinery to automatically guide the technician through the LTT process via scanned indicators. The system serves itself by providing real-time verification and tracking without requiring external supervision, thereby reducing human error while maintaining safety protocol compliance.
Solution Approach 2:
The system implements continuous feedback by tracking each step of the LTT process and providing real-time notifications to both the technician and supervisor. This feedback mechanism ensures compliance by immediately alerting parties if a step is missed or performed incorrectly, thereby improving reliability while guiding operation.
2Reliability
If detailed Lockout/Tagout procedures are provided to ensure proper execution, then safety can be maintained, but the process becomes complex and difficult to track
Solution Approach 1:
The system replaces complex manual tracking mechanisms with an automated digital tracking system. Indicators with unique identifiers are scanned by user devices, automatically recording each step of the LTT process. This substitution eliminates the need for complex paper-based or manual tracking systems while maintaining detailed safety protocol execution.
Solution Approach 2:
The system uses digital copies of the LTT process steps through scanned indicators and electronic records. Instead of managing complex physical documentation, the system creates and manages digital copies of each step's completion status, making tracking simpler while ensuring all safety protocols are executed.
3Loss of information
If manual tracking of Lockout/Tagout processes is performed, then some record-keeping can be achieved, but practical tracking and recording methods are lacking in manufacturing facilities
Solution Approach 1:
The system performs self-service tracking by automatically recording each LTT step through indicator scanning. The machinery itself generates the tracking record when its indicator is scanned, eliminating the need for manual record-keeping efforts while ensuring accurate process information is captured and stored.
Solution Approach 2:
The system substitutes manual record-keeping with an automated electronic tracking system. Scanned indicator data is automatically transmitted and stored in a database, replacing cumbersome manual tracking methods with a simple scan-and-record process that is easy to implement and maintains accurate process information.

AI summary
Systems and methods for performing a Lock-Tag-Try (LTT) process. A computing device may scan an indicator and request a content item associated with the indicator. The computing device may receive the one or more content items associated with the indicator. The one or more content items are configured to guide a user through the LTT process. A server may be configured to receive the request and transmit the content item to the user device. The server may be further configured to store information related to the LTT process.
