LFC File Format Compressing Data While Keeping Headers Readable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large radiation pattern files occupy significant disk space and slow down file transfers due to their bulky nature, and existing compression methods compress headers as well, making them unreadable.
Innovation Solution
The .LFC file format compresses radiation pattern data while maintaining the header in a human-readable format using a column-wise data table descriptive language, allowing for a non-compressed header and compressed data block.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If general-purpose file compression utility is used to compress radiation pattern data files, then file size is reduced, but the header becomes non-human-readable
Solution Approach 1:
The patent divides the file into two distinct segments: a header section that remains in human-readable format and a data section that is compressed. This segmentation allows different parts of the file to be treated differently, with the header preserved for readability and the data compressed for size reduction.
Solution Approach 2:
The patent extracts the header from the rest of the file content and handles it separately. By taking out the header portion and preserving it in its original readable format while compressing only the data portion, the solution maintains header accessibility while achieving overall file size reduction.
2Ease of operation
If radiation pattern data files are stored in simple ASCII text format, then header readability is maintained, but file size becomes bulky
Solution Approach 1:
The patent applies different quality characteristics to different parts of the file: the header maintains high readability quality in human-readable format, while the data portion is optimized for compactness through compression. This local differentiation of quality attributes resolves the contradiction between readability and size.
Solution Approach 2:
The patent changes the format parameter of different file sections: the header remains in ASCII text format for readability, while the data section is transformed into a compressed binary format. This parameter change allows the file to achieve both readability where needed and compactness where possible.
3Ease of operation
If large radiation pattern files are stored without compression, then header readability is preserved, but disk space consumption increases and file transfer speed decreases
Solution Approach 1:
By segmenting the file into readable header and compressed data sections, the patent enables selective optimization: the header remains accessible for quick inspection while the compressed data portion reduces overall transfer time and storage requirements.
