HMI Storage Switching During Recording Without Data Corruption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing HMI systems face issues with data corruption and omission during the replacement of external storage apparatuses, leading to file damage and data loss.
Innovation Solution
A method for changing storage apparatuses in HMI systems that involves recording data to a first storage apparatus, confirming connection of a second storage apparatus, displaying a selection window, receiving a selection signal, and re-performing data recording to the second storage apparatus, ensuring seamless data transfer without corruption or omission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data recording is stopped during storage apparatus replacement, then data corruption and omission are prevented, but data recording continuity is interrupted
Solution Approach 1:
The system detects the connection of a new storage apparatus in advance and proactively displays a selection window to the user before data corruption can occur. This preliminary detection and user notification allows for planned switching rather than reactive interruption, maintaining data integrity while minimizing recording continuity disruption.
Solution Approach 2:
The system continuously monitors the connection status of storage apparatus and provides feedback to the user through a selection window when a new apparatus is detected. This feedback mechanism enables the user to make informed decisions about data recording continuity versus data integrity, resolving the contradiction through user-aware system response.
2Quantity of substance
If storage apparatus is replaced during data recording, then storage capacity is increased, but data corruption and omission occur
Solution Approach 1:
The system performs preliminary detection of new storage apparatus connection and notifies the user before switching occurs. This advance warning allows the user to prepare for the transition, ensuring that data integrity is maintained while still enabling the expansion of storage capacity through replacement.
Solution Approach 2:
The selection window acts as an intermediary mechanism between the storage apparatus replacement action and the data recording process. It mediates the transition by requiring user confirmation, thereby preventing direct switching that would cause data corruption while still allowing capacity expansion when properly executed.
3Duration of action of stationary object
If automatic switching between storage apparatus is implemented, then data recording continuity is maintained, but user control and data integrity verification are reduced
Solution Approach 1:
The system dynamically adjusts its operation mode based on user input. It can operate in an automatic mode that maintains recording continuity or in a manual mode that prioritizes user control and verification. This dynamic flexibility allows the system to adapt to different user preferences and operational requirements.
Solution Approach 2:
The system provides self-service by automatically detecting new storage apparatus and presenting switching options to the user. This reduces the burden on users while still maintaining their control over the data integrity decisions, balancing automation with user agency.
