Programmable Display Backup Synchronization for Device Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing programmable display devices require significant user effort and workload to manage data backups, especially when there are changes in the device organization or when common data is updated, as users need to manually set up new devices and update data across the network.
Innovation Solution
A programmable display device system that includes a storage device with individual memory areas for each device, where each device loads its data and updates state management information, allowing for automatic data backup and synchronization without requiring extensive user intervention during changes in device organization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If programmable display devices perform mutual backups by obtaining and retaining backup data from one another, then data backup functionality is achieved, but user workload increases significantly when there are changes in device organization or data updates
Solution Approach 1:
The system enables automatic mutual backup operations where programmable display devices autonomously perform data exchange and synchronization without requiring user configuration. Devices automatically identify each other on the network, establish backup relationships, and synchronize data changes, eliminating the need for users to manually set up backup partnerships or update settings when devices are added or replaced.
Solution Approach 2:
The system implements automatic detection and synchronization mechanisms where devices monitor for data changes and automatically initiate backup operations. When a device detects that common data has been updated, it automatically notifies other devices and triggers synchronization, ensuring all devices have the latest data without user intervention.
2Reliability
If a separate backup device is used to collectively retain backup data from multiple programmable display devices, then data backup is achieved, but automatic data synchronization between devices cannot be realized
Solution Approach 1:
Instead of using a single centralized backup device, the system segments the backup functionality across multiple programmable display devices themselves. Each device maintains backup data locally and can independently synchronize with others, distributing the backup function throughout the network rather than concentrating it in one device.
Solution Approach 2:
The system uses network communication as an intermediary mechanism to enable direct peer-to-peer data exchange between programmable display devices. This eliminates the need for a separate backup device while still achieving collective data retention and automatic synchronization through the network medium.
3Reliability
If mutual backup settings are configured for all programmable display devices, then data backup is ensured, but any change in device organization requires extensive reconfiguration
Solution Approach 1:
The system implements dynamic backup relationships that automatically adapt to changes in device organization. When new devices are added or existing devices are replaced, the system dynamically reconfigures backup partnerships without requiring static pre-configuration. Devices automatically discover each other and establish appropriate backup relationships based on current network topology.
Solution Approach 2:
The system creates universal backup capabilities where any programmable display device can serve as a backup partner to multiple other devices. This multi-functional approach eliminates the need for specific one-to-one pairing configurations, allowing devices to seamlessly assume backup roles as organizational changes occur.

AI summary
A programmable display device for a production system that includes a storage device and a plurality of the programmable display devices. The storage device includes a plurality of individual memory areas that store data from the plurality of the programmable display devices individually and are associated with any one of the plurality of the programmable display devices. There is a backup processing unit that loads some or all data that the programmable display device itself retains into an individual memory area associated with the programmable display device itself among the plurality of individual memory areas and a state management unit that updates state management information retained in the storage device when the backup processing unit has performed data update within the individual memory area associated with the programmable display device itself. The state management information indicates that data retained by the plurality of individual memory areas have been updated.
