Communication Device Identification Backup for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication devices fail to appropriately determine the replacement status of components and take over the latest identification information item when the communication module or backup mechanism is replaced, leading to disruptions in service continuity.
Innovation Solution
A communication device with a detachable control section and communication section, featuring a memory system that determines the replacement status of components and updates the identification information item in the backup memory, ensuring the device takes over the latest identification information item based on the presence and backup status of the information item.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the communication module is replaced with a new one having a different identification information item, then the device can be repaired or upgraded, but the communication device cannot continuously receive services from the management device
Solution Approach 1:
The system performs preliminary backup of the identification information item from the communication module to the control module's storage section before replacement occurs. This preliminary action ensures that the original identification information is preserved and can be restored after replacement, maintaining service continuity while allowing the communication module to be replaced for repair or upgrade purposes.
2Reliability
If a multiple backup mechanism is implemented to preserve identification information, then service continuity is maintained, but the system cannot adapt when both the communication module and backup mechanism are replaced simultaneously
Solution Approach 1:
The control module serves as an intermediary storage section that receives and preserves the identification information item from the communication module. This intermediary mechanism decouples the dependency between the communication module and the backup mechanism, allowing the system to adapt when both are replaced simultaneously, as the control module can still provide the original identification information for service continuity.
3Device complexity
If the identification information item is stored only in the communication module, then the system structure is simple, but the identification information is lost when the communication module is replaced
Solution Approach 1:
The system creates a copy of the identification information item from the communication module's memory and stores it in the control module's storage section. This copying mechanism ensures that the identification information is preserved in a separate location, preventing information loss when the communication module is replaced, while adding only minimal structural complexity with an additional storage section.

AI summary
In a case where an identification information item determination section (411) determines that a first identification information item indicates a non-replacement part, a first backup section (412) backs up the first identification information item in a backup memory (420). In a case where a confirmation section (413) determines that the first identification information item is not backed up in the backup memory (420), a second backup section (414) backs up the first identification information item in the backup memory (420). In a case where the confirmation section (413) determines that the first identification information item is backed up in the backup memory (420), a storage process section (415) updates the first identification information item stored in a communication section-side memory (430) with a second identification information item stored in the backup memory (420).
