File Name Control for Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices require users to perform multiple manipulations to rename a file after attachment for data transmission, involving detachment, renaming, and reattachment, which is inefficient.
Innovation Solution
An electronic device method that detects renamed files and generates a header for data transmission based on the changed file name, using a file management table and flag system to streamline the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user renames a file after attachment for data transmission, then the file name can be changed to meet user needs, but the user must perform five manipulations (detach, rename, attach again, update header, transmit) which increases operation complexity and time consumption
Solution Approach 1:
The system performs preliminary actions by maintaining a flag that indicates whether a file has been renamed before attachment. When a data transmission event occurs, the system checks this flag and automatically updates the header with the new filename if renaming is detected, eliminating the need for manual detachment and reattachment operations
Solution Approach 2:
The system implements feedback mechanisms by setting a flag when a file is renamed and using this flag information during data transmission to automatically update headers. This feedback loop allows the system to detect renamed files and adjust transmission parameters automatically, reducing manual intervention steps
2Productivity
If the system automatically detects and handles renamed files, then the file renaming process is simplified and time is saved, but the system complexity increases due to additional detection and header generation mechanisms
Solution Approach 1:
The system extracts the essential information needed for file management by using a simple flag variable to indicate whether a file has been renamed. This extraction approach captures the necessary state information without requiring complex detection mechanisms, thereby improving productivity while limiting the increase in system complexity
Solution Approach 2:
The flag-based mechanism serves multiple functions: it tracks renamed files, triggers header updates, and manages transmission parameters. This multi-functionality approach consolidates what would otherwise require separate complex systems into a single unified mechanism, improving efficiency without proportionally increasing complexity

AI summary
A method for controls a file name in an electronic device. The method includes when a data transmission event occurs, detecting at least one file for attachment to data transmission; determining whether a renamed file exists among the at least one file; when at least one renamed file exists, generating a header in consideration of a changed name with respect to the at least one renamed file; and generating and transmitting a data packet including the header.
