Vehicle Storage Updates Using Partial Character String Writes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices face limitations in managing data efficiently due to limited write operations, leading to unnecessary data storage and increased access frequency.
Innovation Solution
An information processor and method that selectively stores only characters in the start direction relative to a specific character in a character string, deleting characters in the end direction to create a shortened data piece for storage, thereby reducing the amount of data stored and minimizing unnecessary access to the storage device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the storage device stores the complete character string including characters in the end direction relative to the specific character, then the data完整性 is maintained, but the amount of data stored increases and write operations increase
Solution Approach 1:
The patent extracts and stores only the necessary portion of the character string (characters in the start direction relative to the specific character) while discarding the unnecessary portion (characters in the end direction). This extraction principle reduces the storage quantity while maintaining data integrity for the required functionality.
2Reliability
If the storage device stores the complete character string, then all data is preserved, but the access frequency increases due to unnecessary data retrieval
Solution Approach 1:
By extracting and storing only the necessary character portion (start direction characters), the system reduces the amount of data that needs to be retrieved during access operations, thereby improving access efficiency while maintaining the required data completeness for the specific character and its preceding characters.
3Reliability
If the storage device performs frequent write operations to update complete character strings, then data is kept up-to-date, but the storage device durability decreases due to limited write operations
Solution Approach 1:
The patent applies extraction by storing only the necessary character portion rather than the complete string. This reduces the volume of data written to the storage device during updates, thereby reducing the frequency and total number of write operations, which extends the storage device lifespan while maintaining data freshness.
Solution Approach 2:
Instead of performing full write operations on the complete character string, the system performs partial write operations only on the necessary start direction characters. This partial action principle reduces the write operation burden on the storage device, extending its operational duration while maintaining adequate data updates.
Data Source
AI summary
An information processor and an information processing method are provided. Processing circuitry receives a data piece from another controller to manage a storage device provided in a vehicle. The data piece includes a character string. The character string includes a specific character and one or more start direction characters. The one or more start direction characters are one or more characters positioned in a start direction relative to the specific character in the character string. The processing circuitry writes only the one or more start direction characters to the storage device to update a stored content of the storage device.
