Edge Device Data Management for Memory Capacity Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively manage data storage as the amount of data exceeds the capacity of the recording device, leading to issues with data utilization and storage capacity management.
Innovation Solution
A data management method that generates maintenance data to monitor memory capacity, transfers alert notification data based on this information, and relocates existing data to free up storage space, allowing for continued data collection and utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data is continuously stored in a memory device with limited capacity, then the amount of stored data increases, but the memory capacity is exceeded and data cannot be retained
Solution Approach 1:
The system segments data management across multiple storage locations including local memory device and external storage devices. When the local memory capacity is exceeded, data is transferred to external storage devices, effectively dividing the storage system into multiple segments that can collectively hold larger amounts of data without losing reliability.
Solution Approach 2:
The system transitions from a single-dimension local storage approach to a multi-dimensional storage architecture by introducing external storage devices as an additional dimension. This allows data to be distributed across different storage dimensions (local memory, external storage), resolving the contradiction between storage capacity and data retention.
2Quantity of substance
If new data overwrites old data in a full memory, then storage capacity is maintained, but historical data is lost and cannot be used effectively
Solution Approach 1:
The system performs preliminary actions by proactively transferring data to external storage devices before the local memory becomes completely full. This preventive measure ensures that historical data is preserved in external storage while maintaining adequate space in local memory for new data, avoiding the need to overwrite important historical data.
Solution Approach 2:
External storage devices serve as intermediaries between the local memory and the need for historical data preservation. They temporarily hold data that is being transferred from local memory, allowing the system to maintain both storage capacity and historical data without direct overwriting conflicts.
3Quantity of substance
If data is transferred to external storage devices, then local memory capacity is freed up, but data access time increases due to external transfer
Solution Approach 1:
The system dynamically manages data distribution between local memory and external storage based on current capacity needs and access patterns. Data is transferred to external storage when local capacity is needed, and can be retrieved when required, creating a dynamic balance between maintaining local capacity and minimizing access time delays.
Solution Approach 2:
The system changes the storage location parameter of data based on system state. When local memory capacity becomes limited, the storage location parameter changes from local to external. This parameter change allows flexible adaptation to maintain optimal performance between capacity utilization and access speed.

AI summary
According to one embodiment, data stored in past can be effectively used without being influenced by the characteristics and capacity of a memory storing storable data. Maintenance data are generated by managing a state in a memory area, alert notification data are transferred on the basis of the generated maintenance data, and/or at least a part of the data which are already stored in the memory area is transferred.
