Abnormal-State Notification Routing for Unattended Mobile Bodies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a mobile body experiences an abnormal state during unattended operation, notifications sent to all workers and stations may reach those who are not suitable to take action, leading to inefficiencies and potential delays.
Innovation Solution
A notification device that receives signals indicating an abnormal state of a mobile body and specifies a notification target based on pre-defined conditions, ensuring that only appropriate workers and stations receive instructions for handling the abnormal state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notifications are sent to all workers and stations when an abnormal state occurs, then all potential responders are alerted, but unnecessary notifications are sent to workers and stations that cannot handle the abnormal state
Solution Approach 1:
The notification system applies local quality by differentiating notification targets based on their specific capabilities and locations. Workers and stations are selectively notified based on whether they meet specification conditions (such as being able to handle the abnormal state, proximity to the mobile body, or current work status), rather than notifying all workers uniformly. This ensures notification resources are concentrated on appropriate targets.
Solution Approach 2:
The set of all workers and stations is segmented into multiple groups based on their ability to handle abnormal states. The notification system divides the notification task by identifying specification targets that meet predetermined conditions (such as workers at specific locations, stations with relevant capabilities, or workers not engaged in more urgent tasks), and sends notifications only to these segmented subsets rather than the entire workforce.
2Reliability
If notifications are sent to all workers and stations, then comprehensive coverage is achieved, but response efficiency decreases due to unnecessary actions
Solution Approach 1:
The system enhances response efficiency by applying local quality to notification delivery - each worker or station receives a notification only if they possess the specific local capability to handle the abnormal state. Specification conditions filter targets based on factors such as proximity to the mobile body, availability, and relevance to the abnormal state type, ensuring that notified parties can act immediately without needing to assess whether they should respond.
Solution Approach 2:
The notification system segments the workforce into capable and incapable groups based on predetermined specification conditions. By dividing all workers and stations into subsets that meet the conditions (such as workers within a certain distance, stations with relevant equipment, or workers not performing more urgent tasks), the system ensures that only the capable segment receives notifications, thereby maximizing response efficiency while maintaining comprehensive coverage of appropriate targets.
3Ease of manufacture
If a simple notification system is used, then implementation is easy, but appropriate notification targets cannot be identified
Solution Approach 1:
The notification system applies preliminary action by pre-establishing specification conditions that define suitable notification targets before any abnormal state occurs. These conditions (such as location proximity, work capability, current task status, and relevance to abnormal state types) are predetermined and stored in the notification device. When an abnormal state occurs, the system automatically evaluates potential targets against these pre-set conditions, eliminating the need for complex real-time analysis while ensuring appropriate targets are identified.
Data Source
AI summary
A notification device includes a processor, and the processor is configured to: receive a signal that indicates occurrence of an abnormal state of a mobile body that is movable through unattended operation, and specify a notification target that meets a specification condition determined in advance from one or more specification targets that include at least one of a worker and a station; and send a notification to instruct handling of the abnormal state of the mobile body to the specified notification target.
