Solution Overview
Problem
Current lockout/tagout systems are cumbersome and inconvenient for multiple users, leading to non-compliance due to disorganization and lack of remote monitoring capabilities, which can result in workplace safety issues and accidents.
Innovation Solution
A lockout system with a hasp assembly and tags that can be easily managed, featuring a sliding locking bar, electronic display, and wireless communication to a database, allowing for secure locking and remote tracking of energy sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional lockout/tagout systems with multiple locks and tags are used, then energy sources can be controlled, but the system becomes cumbersome and difficult to manage for multiple users
Solution Approach 1:
The patent combines multiple lockout/tagout functions into a single integrated hasp assembly that can accommodate multiple tags. The hasp assembly integrates the locking mechanism, tag holders, and control features into one unified device, eliminating the need for separate locks and tags for each user while maintaining reliable energy source control.
Solution Approach 2:
The hasp assembly is designed as a universal device that can serve multiple users simultaneously through multiple tag slots. A single hasp assembly can accommodate multiple tags from different workers, providing multi-functionality that replaces the need for individual lockout devices for each user while maintaining reliable energy isolation.
2Reliability
If traditional lockout/tagout systems are used, then energy sources can be locked out, but remote monitoring and tracking capabilities are lacking
Solution Approach 1:
The patent incorporates electronic monitoring capabilities that provide feedback about the lockout status to remote locations. Sensors detect whether the hasp assembly is locked or unlocked and transmit this information to supervisors or control systems, enabling remote monitoring and immediate notification of unauthorized access attempts.
Solution Approach 2:
The patent replaces purely mechanical lockout systems with an integrated system that incorporates electronic sensors, transmitters, and communication capabilities. This substitution of mechanical-only approaches with electromechanical systems enables remote tracking and monitoring of lockout effectiveness without compromising the physical locking function.
3Reliability
If multiple locks and tags are used for each user, then individual accountability is maintained, but the system becomes disorganized and compliance decreases
Solution Approach 1:
The patent segments the identification function from the locking function by providing dedicated tag slots within the hasp assembly. Each user's tag is held in a designated slot, providing individual accountability through organized tag placement while maintaining system simplicity. The segmentation of tag identification from the mechanical locking mechanism reduces overall system complexity.
Solution Approach 2:
The patent nests multiple tag holders within the single hasp assembly structure. Each user's tag is contained within the broader hasp assembly, creating a nested organization where individual accountability is maintained through separate tag slots while the overall system remains unified and organized rather than scattered and complex.

AI summary
A lockout system includes a hasp assembly and a plurality of tags. The hasp assembly has a back plate defining slots each sized and shaped to receive a tag. The back plate and tags each have openings that align when a tag is received in a slot. A first hasp portion has a first loop portion and a second hasp portion has a second loop portion. The first and second hasp portions are rotatable with respect to one another such that moving the lockout system has both an unlocked position and a locked position associated with an open position and a closed position. In the closed position, the first and second hasp portions complete and define a closed loop, where one or more tags can be installed in slots preventing further movement from the closed position.
