Operator Alert Cancellation Using Position-Based Responder Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to efficiently manage and handle irregularities in equipment by minimizing unnecessary labor and ensuring prompt response from operators.
Innovation Solution
An alert system that includes a notification server and operator terminals, which detect equipment irregularities, notify operators, and cancel notifications for non-responding operators to prevent redundant efforts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an irregularity notification is transmitted to all operators, then the probability of finding a responder increases, but unnecessary labor is incurred when multiple operators respond to the same irregularity
Solution Approach 1:
The notification server continuously monitors operator positions and provides feedback by detecting when an operator has approached the irregularity location. Based on this feedback, the server automatically transmits cancellation notifications to stop further responses from other operators, thus preventing unnecessary labor while maintaining high reliability of finding a responder
Solution Approach 2:
The system transmits cancellation notifications in advance before multiple operators can arrive at the irregularity location. By detecting the movement of the first responder and preemptively canceling notifications to other operators, the system prevents the wasteful scenario where multiple operators would otherwise respond to the same irregularity
2Productivity
If the system monitors operator positions continuously, then it can detect moving users and cancel notifications efficiently, but the device complexity and energy consumption increase
Solution Approach 1:
Operator terminals automatically transmit their position information to the notification server without requiring manual input or complex local processing. The server performs all the complex tasks of monitoring, analyzing, and determining when to send cancellation notifications, thereby keeping the operator terminals simple while achieving high productivity
Solution Approach 2:
The notification server performs multiple functions: it sends irregularity notifications, monitors position information from multiple operators, detects movement toward the irregularity, and transmits cancellation notifications. This multi-functionality consolidates complexity into a single central system rather than distributing it across multiple terminals

AI summary
An alert device for alerting an irregularity in equipment installed in an environment to users, including: a communication interface performing data communication with terminal devices respectively associated with the users; a controller controlling the communication interface; a state information obtainer acquiring state information indicating a state of the equipment; and a position information obtainer acquiring position information indicating a position of each user in the environment, wherein the controller: upon specifying that the equipment is in an irregular state based on the state information, transmits an irregularity notification, indicating that the equipment is in the irregular state, to the terminal devices; then detects a moving user to the irregular equipment based on the position information; and when the moving user is detected, transmits a cancellation notification indicating cancellation of the irregularity notification to a part or all of the terminal devices to which the irregularity notification is transmitted.
