Smart Key Offline Task Synchronization via Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart lock-and-key systems are inefficient due to tedious task acceptance and result uploading processes, lack of real-time monitoring, and synchronization issues with changing equipment status, leading to potential misoperations.
Innovation Solution
A smart lock-and-key system with a smart key that communicates via Bluetooth, ZigBee, or Z-Wave interfaces with a mobile computing device and a remote server, allowing for real-time validation and operation commands, and subsequent status updates, enabling online or semi-online operations to prevent human errors and ensure safety protocols are followed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the smart key downloads tasks and stores them locally, then the system can operate offline, but the task status cannot synchronize with equipment status changes, leading to potential misoperation
Solution Approach 1:
The patent implements a feedback mechanism where the smart key continuously uploads task execution status to the control system, which then compares it with current equipment status. When inconsistencies are detected (e.g., equipment status changed but task status not updated), the control system sends correction instructions back to the smart key, ensuring synchronization between stored tasks and actual equipment state.
2Loss of information
If the smart key uploads operation results after completion, then the control system can record the operation, but the system administrator cannot monitor status in real time, reducing system efficiency
Solution Approach 1:
The patent transforms the intermittent upload process into a continuous monitoring action. The smart key continuously uploads task status and operation results to the control system in real-time, enabling system administrators to monitor equipment status and task progression continuously rather than receiving periodic updates only after task completion.
3Ease of operation
If the smart key accepts and saves tasks before operation, then the operation can be performed, but the process is tedious and time-consuming, reducing system efficiency
Solution Approach 1:
The patent applies preliminary action by having the control system pre-validate tasks against current equipment status before they are downloaded to the smart key. This ensures that only relevant and safe tasks are transmitted to the field device, eliminating the need for extensive local validation processes and reducing the overall task acceptance time.

AI summary
One embodiment of the present invention provides a smart lock-and-key system. The smart lock-and-key system can include a smart lock corresponding to a lock identifier and a smart key capable of locking and unlocking the smart lock. The smart key can include a first communication interface for communicating with the smart lock and a second communication interface for communicating with a mobile computing device. The smart key can be configured to obtain the lock identifier and receive, from the mobile computing device, an operation command based on the obtained lock identifier.
