Document Scan Indexing via Separate Index Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for storing and searching scan files generated by document scanning are cumbersome, requiring index information derived from file data, which leads to user operability issues and increased storage strain due to unnecessary duplication.
Innovation Solution
A storage method that generates scan data by scanning documents, acquires index information independent of document data, and assigns this index information to the scan data for efficient storage and retrieval, using a multifunction peripheral with a reader, controller, and storage device to improve user operability and reduce storage strain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If index information is derived from file data (file name, contents, property information), then the search function is established, but user operability deteriorates and storage capacity is strained due to necessary file duplication
Solution Approach 1:
The patent separates index information from the original file data by creating a distinct index table that stores only essential search criteria (user name, date, category) without duplicating full file contents. This segmentation allows efficient searching while minimizing storage requirements.
Solution Approach 2:
The patent extracts only the necessary search-related attributes (user name, date, category) from the complete file data and stores them separately in an index table. This extraction eliminates the need to store or process entire file contents for search operations, reducing storage strain.
2Productivity
If index information is derived from file data, then the search function is established, but the work of rewriting property information and specifying folders becomes troublesome
Solution Approach 1:
The patent performs preliminary organization by automatically assigning standardized index values (user name, date, category) to each file during the indexing process. This preliminary action eliminates the need for users to manually rewrite property information or specify folders during search operations.
Solution Approach 2:
The patent introduces an intermediary index table that mediates between the user's search requirements and the actual file storage. This intermediary layer handles all search operations through simple criteria without requiring users to interact with complex file property rewriting or folder specification processes.
3Adaptability or versatility
If files are duplicated to accommodate folder specification, then the save location can be specified, but storage capacity is strained
Solution Approach 1:
The patent extracts the essential organizational information (user name, date, category) from the file system structure and stores it in a compact index table. This extraction eliminates the need to physically duplicate files across multiple folders while maintaining the ability to specify and access files by organizational criteria.

AI summary
According to an embodiment, a storage method includes: a step of generating scan data by scanning of a document with a reading device; a step of acquiring index information that is different from information that is based on the document; and a step of assigning the acquired index information to the scan data and storing the scan data to which the index information is assigned in a storage device.
