Contactless Data Writing Corruption Detection Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing contactless communication systems for data storage mediums, such as those used in game apparatuses, face issues with data corruption during writing processes, leading to unusable data when communication is interrupted or incomplete.
Innovation Solution
Incorporating a contactless communication part for data writing and a corruption determination part in the game apparatus, which stores data in a secondary storage medium and restores corrupted data by writing it back to the data storage medium when corruption is detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contactless communication is used to write data to a data storage medium, then data transfer convenience is improved, but data corruption may occur during the writing process
Solution Approach 1:
The system performs preliminary actions by storing backup data in the storage part before writing to the data storage medium, and by determining data completeness before finalizing the write operation. This ensures that if corruption occurs during the writing process, the backup data can be restored to maintain data integrity while preserving the convenience of contactless data transfer.
2Productivity
If data is written to a data storage medium without verification, then writing speed is improved, but data corruption remains undetected
Solution Approach 1:
The system implements feedback mechanisms by having the corruption determination part verify data completeness and correctness after the writing operation. This feedback loop allows the system to maintain high writing speeds while detecting and addressing data corruption issues, ensuring data correctness without significantly impacting productivity.
3Device complexity
If no backup storage is used, then device complexity is reduced, but data recovery capability is lost when corruption occurs
Solution Approach 1:
The system creates a copy of the data in the storage part before writing to the data storage medium. This copying mechanism provides data recovery capability without significantly increasing device complexity, as the backup storage uses the same storage resources already present in the apparatus. The copy allows for easy data restoration if corruption occurs.
4Ease of operation
If contactless communication distance is increased, then ease of use is improved, but data transmission reliability decreases
Solution Approach 1:
The system performs preliminary data validation and completeness determination before finalizing the data transmission to the data storage medium. This preliminary action ensures that even when data is transmitted over longer distances with potential reliability issues, the system can detect and prevent corrupted data from being stored, maintaining both ease of use and transmission reliability.
Data Source
AI summary
An example system includes: a contactless communication part that performs contactless communication with a data storage medium having a contactless communication function; a data writing part that writes data to the data storage medium by the contactless communication part; a storage part that stores the data written by the data writing part; and a corruption determination part that determines whether the data stored in the data storage medium is corrupted or not. When the corruption determination part determines that the data is corrupted, the data writing part writes the data stored in the storage part, to the data storage medium.
