Local Controller Backup for Mobile Device Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack a reliable method for maintaining network connectivity and device assignment during server maintenance or failures, leading to potential operational disruptions.
Innovation Solution
A controller apparatus with interfaces for mobile electronics devices and a server, which creates and stores device assignment records locally when the server is offline, and updates the server with these records when it returns online.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the system relies on a centralized server for device assignment records, then centralized control and data consistency are improved, but system reliability deteriorates when the server is offline or fails
Solution Approach 1:
The patent segments the device assignment record storage function between the centralized server and local controller apparatus. The server maintains the primary record while the controller apparatus maintains a local copy, allowing operations to continue locally even when the server is unavailable. This segmentation resolves the contradiction by distributing the critical function across multiple locations.
Solution Approach 2:
The controller apparatus performs preliminary action by creating and storing device assignment records locally in advance, before needing to access the server. This allows the system to maintain operational capability during server outages, improving reliability while still enabling centralized updates when the server is available.
2Reliability
If the system operates in offline mode without server connectivity, then system availability is improved, but data consistency and assignment accuracy deteriorate
Solution Approach 1:
The system performs preliminary action by establishing device assignment records locally before offline operations begin. This pre-established data allows the system to operate consistently during offline periods without losing information or creating conflicts, as the local records serve as a reliable reference during server unavailability.
Solution Approach 2:
The system implements feedback by continuously synchronizing local device assignment records with the server when connectivity is restored. This feedback mechanism ensures that any changes made during offline operation are detected and resolved, maintaining data consistency across the distributed system while preserving offline availability.
3Stability of the object's composition
If device assignment records are stored only on the server, then data security and centralized management are improved, but operational continuity deteriorates during server maintenance or failures
Solution Approach 1:
The patent segments the storage function by maintaining device assignment records both on the centralized server and in local memory of the controller apparatus. This dual-storage approach allows centralized management to remain the primary model while providing local redundancy that ensures operational continuity during server maintenance or failures.
Solution Approach 2:
The system applies beforehand cushioning by creating local copies of device assignment records in advance, before server failures or maintenance occur. This preparatory measure cushions the system against potential disruptions, ensuring that critical assignment information remains accessible and operational continuity is maintained even when the server is unavailable.
4Loss of information
If the system continuously synchronizes with the server, then data consistency is improved, but network dependency and vulnerability to connectivity issues increase
Solution Approach 1:
The patent segments the synchronization function by implementing it only when needed - specifically when the server transitions from offline to online mode. This selective synchronization approach maintains data consistency without requiring continuous network connectivity, reducing network dependency while preserving data integrity through periodic updates at critical transition points.
Data Source
AI summary
A method, system and computer program product for backup assignment of a mobile electronics device is disclosed. In response to one or more device assignment requests received by a controller apparatus when a server is operating in an off-line mode, one or more device assignment records are created within the controller apparatus, and which indicate assignment of the at least one mobile electronics device to a respective one or more users. When the server is operating in an off-line mode such that communication between the controller apparatus and the server is off-line, the one or more device assignment records, in relation to the at least one mobile electronics device, are stored in the controller apparatus. In response to the server re-entering the on-line mode, the server is updated with the one or more device assignment records.
