Pen Data Storage with Embedded Function Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face difficulties in efficiently storing and processing pen data without the need for file opening, as well as determining appropriate processing applications for pen data stored in units of files or without file extensions, leading to unclear usage and reproduction of pen data.
Innovation Solution
A pen data storage apparatus that stores pen data with function identification information, allowing for direct processing and reproduction of pen data without the need for file opening, by associating each piece of data with a specific processing function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pen data is stored in units of files with extensions indicating processing applications, then the processing application can be identified, but the process of opening files to extract pen data becomes troublesome and inefficient
Solution Approach 1:
The patent extracts the essential identification information (extension indicating processing application) from the file structure and embeds it directly within the pen data itself. This allows the processing application to be identified without needing to open or parse the file structure, thereby eliminating the troublesome file opening process and reducing extraction time.
Solution Approach 2:
The patent performs preliminary action by pre-embedding the extension information that identifies the processing application directly into the pen data structure before storage. This preliminary inclusion of identification information eliminates the need for subsequent file opening and extraction operations, as the processing application can be immediately identified from the embedded information.
2Productivity
If pen data is stored without file extensions or in units other than files, then file opening is not necessary, but it becomes unclear what processing application should be used and difficult to reproduce the usage
Solution Approach 1:
The patent merges the identification information about the processing application (extension) directly with the pen data into a unified data structure. This combination ensures that the pen data contains all necessary information about which processing application should be used, eliminating the need for separate file extensions while maintaining complete information for reproduction and processing.
3Adaptability or versatility
If a large amount of pen data and biological information is collected and stored, then emotion estimation and analysis become possible, but the system complexity and data management burden increase
Solution Approach 1:
The patent segments the data storage system into distinct, well-defined components with standardized structures. By organizing pen data and associated information into structured units with clear formats and embedded identification information, the system can handle large amounts of diverse data (including biological information for emotion estimation) without proportionally increasing complexity. The segmentation allows for modular data management.
