Electronic Lock On-Site Authorization via Manager Mobile Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic door lock systems require authorization from a management server via a card reader to grant or revoke unlocking authority for door access cards, which is inconvenient and inefficient, especially in scenarios where immediate access or revocation is needed.
Innovation Solution
A method using a manager mobile device to directly write unlocking authority into a door access card, allowing the lock to grant or cancel access without relying on the server, by selecting the lock, outputting a writing command, and writing the unlocking authority into the card, thereby enabling on-site management of access permissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authorization is performed through a management server via a card reader, then centralized control and security management are improved, but operational efficiency and response time are worsened due to the need to return to the server end for authorization operations
Solution Approach 1:
The system segments the authorization function from the central management server and assigns it to individual electronic locks. Each lock can independently perform authorization operations by receiving writing commands from manager mobile devices, eliminating the need to return to the server for each authorization action while maintaining security through the mobile device's authentication.
Solution Approach 2:
The manager mobile device acts as an intermediary between the centralized management system and the electronic locks. It receives authorization commands from the server, authenticates the manager, and then transmits writing commands to the appropriate locks, enabling decentralized operation while maintaining centralized control policies.
2Productivity
If a manager mobile device directly writes unlocking authority into a door access card via the lock, then operational efficiency and response time are improved, but system complexity increases due to the need for direct lock-card communication and management mode interfaces
Solution Approach 1:
The electronic lock is given multiple functions: it serves as both a security device for unlocking and as a portable authorization unit that can write unlocking authority to access cards. The lock's communication interface and memory are utilized for both traditional unlocking operations and the new authorization writing function, reducing the need for separate dedicated hardware.
Solution Approach 2:
The electronic lock performs the authorization writing operation autonomously when it receives a writing command from an authenticated manager mobile device. The lock itself writes the unlocking authority to the access card without requiring external authorization equipment, enabling the system to serve itself for authorization operations.
3Adaptability or versatility
If the lock enters a writing mode to write unlocking authority, then authorization flexibility is improved, but security risks increase due to the need for mode switching and direct writing capability
Solution Approach 1:
The electronic lock dynamically switches between identification mode and writing mode based on the received commands. The mode is not fixed but changes according to the operational context, allowing the lock to adapt its behavior to different security requirements while maintaining clear state transitions that can be monitored and controlled.
Solution Approach 2:
The system implements feedback through the manager mobile device's authentication process and the lock's mode switching confirmation. The mobile device receives feedback about whether the manager is authenticated and whether the writing operation was successful, allowing for verification and error correction while maintaining security control.

AI summary
A management method for electronic locks includes obtaining a manager mobile device with management authorities of a plurality of locks. The manager mobile device can be connected any one of the plurality of locks, and the lock connected to the manager mobile device switches to a writing mode. The lock connected to the manager mobile device writes the unlocking authority of at least one of the plurality of locks into a door access card. When the door access card is identified by one of the plurality of locks as being correct, the one of the plurality of locks is unlocked.
