Sensor-Triggered Storage Backup for Emergency Data Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data storage devices, such as SSDs, lack effective methods to securely and efficiently backup data during emergency situations like fire or flooding, which can lead to data loss.
Innovation Solution
A data backup method using environmental sensors to monitor operating conditions, generating event detection signals when conditions exceed a reference range, and immediately backing up critical data through a separate port to external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data is stored in a single storage device without backup mechanism, then storage device complexity is reduced, but data reliability deteriorates during emergency situations
Solution Approach 1:
The patent implements preliminary action by continuously monitoring environmental parameters (temperature, humidity, shock, vibration) and maintaining a backup mechanism in readiness before emergencies occur. When abnormal conditions are detected, the system automatically activates the backup process to transfer data to an external storage device, ensuring data reliability without requiring complex manual intervention during crises.
Solution Approach 2:
The patent introduces an intermediary backup management module that mediates between the primary storage device and external backup storage. This intermediary component handles environmental monitoring, decision-making for backup activation, and data transfer coordination, thereby improving data reliability while keeping the overall system complexity manageable through modular design.
2Reliability
If environmental monitoring and automatic backup system is implemented, then data protection during emergencies is improved, but device complexity increases
Solution Approach 1:
The backup management module performs multiple functions including environmental monitoring, anomaly detection, backup decision-making, and data transfer coordination. By consolidating these diverse functions into a single multi-functional module, the system achieves comprehensive data protection capability while avoiding the complexity increase that would result from separate dedicated components for each function.
Solution Approach 2:
The patent merges the environmental sensing subsystem, anomaly detection logic, backup decision-making mechanism, and data transfer control into an integrated backup management module. This consolidation improves data protection capability by ensuring coordinated operation of all subsystems while reducing overall system complexity compared to having separate independent components.
3Reliability
If data is immediately transferred through the same port used for storage, then device complexity is minimized, but data loss risk increases during emergencies
Solution Approach 1:
The patent segments the data transfer path by designating specific ports for backup operations separate from primary storage ports. This segmentation ensures that backup data transfer can occur independently through dedicated communication channels, preventing data loss during emergencies while maintaining manageable port configuration complexity through clear functional separation.
4Measurement precision
If comprehensive environmental parameters are monitored, then emergency detection accuracy is improved, but device complexity and energy consumption increase
Solution Approach 1:
The patent applies local quality by selecting specific environmental parameters (temperature, humidity, shock, vibration) that are most relevant to detecting emergencies affecting data storage. Rather than monitoring all possible environmental factors, the system focuses on localized quality metrics that directly correlate with storage device safety, thereby improving emergency detection accuracy while keeping sensor system complexity manageable.
Data Source
AI summary
In a data backup method of a storage device, environment information is received from at least one environmental sensor such that an operating environment in which the storage device is operating is monitored. An event detection signal is generated based on the environment information. In response to generating the event detection signal at least first data is immediately backed up to an external device located outside the storage device. The storage device includes a first port configured to be used to store the plurality of data in the storage device, and a second port different from the first port. In response to generating the event detection signal, the at least first data among the plurality of data are immediately output from the storage device through the second port.
