Mobile Robot Locker Access Control During Emergency Unlocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing transport management systems, if the authorized person is unavailable during an emergency, the package storage locker on autonomous mobile units cannot be unlocked, hindering the retrieval of transport articles, as only the specified recipient can unlock the locker.
Innovation Solution
A management system that allows for dynamic security level adjustments, enabling other authorized personnel to unlock the storage locker during emergencies by expanding the range of individuals who can access the locker, based on predefined conditions and notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only a specified recipient is authorized to unlock the storage locker, then security is improved, but accessibility during emergencies deteriorates
Solution Approach 1:
The system dynamically adjusts the set of authorized users based on situational context. During emergency events, the server temporarily expands authorization to include additional users beyond the specified recipient, while maintaining restricted access during normal operations. This dynamic authorization mechanism resolves the contradiction between maintaining high security and enabling emergency accessibility.
Solution Approach 2:
The system changes the authorization parameter (set of permitted users) based on the operational state. When an emergency event is detected through notification reception, the system transitions from a restricted user set (only specified recipient) to an expanded user set (including emergency personnel). This parameter change allows the system to adapt security levels to match operational requirements.
2Reliability
If the storage locker remains locked during emergencies when the authorized person is unavailable, then security is maintained, but operational continuity deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-configuring emergency protocols and pre-identifying alternative authorized users. When an emergency notification is received, the system has already prepared the expanded authorization set, allowing immediate access without delaying for user availability checks. This preliminary preparation ensures both security and operational continuity during emergencies.
Solution Approach 2:
The server acts as an intermediary that mediates between security requirements and emergency access needs. It receives emergency notifications, determines the appropriate expanded authorization set, and manages the temporary access permissions. This intermediary mechanism allows the system to maintain security through controlled access while enabling operational continuity by facilitating emergency retrieval of transport articles.
3Ease of operation
If the security level is lowered during emergencies, then accessibility is improved, but security control deteriorates
Solution Approach 1:
The system dynamically adjusts security levels based on the emergency state. During normal operations, strict security control limits access to the specified recipient only. When an emergency notification is received, the system transitions to a relaxed security state that temporarily expands access permissions to include additional authorized users. This dynamic adjustment ensures appropriate security control for each operational context.
Solution Approach 2:
The system changes the security parameter (authorization set) based on operational conditions. The server receives emergency notifications and responds by modifying the access control parameters to include emergency personnel. This parameter change is temporary and reversible, allowing the system to balance accessibility needs during emergencies with security control requirements during normal operations.

AI summary
A management system includes an autonomously movable mobile robot configured to be managed by the management system and transport a transport article. The mobile robot includes a storage locker capable of containing a transport article and being electrically locked or unlocked. The management system is configured to determine whether to unlock the storage locker according to a security level set for unlocking the storage locker. The management system is configured to, when the management system receives a notification of an emergency event, lower the security level.
