Scanner Storage Area Type Detection and URL Shortening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scanners face issues where scan data uploaded to a data storage server cannot be accessed using different access methods, such as WebDAV and normal HTTP communication, leading to inaccessible scan data when users attempt to access it from a terminal device.
Innovation Solution
A scanner with a processor and memory that determines the type of storage area designated by the user and uploads scan data using the appropriate method, informing the user if the area is inaccessible, and converting long URLs to short URLs for efficient data storage and access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If scan data is uploaded to a storage area accessible by only one access method, then upload functionality is achieved, but data accessibility from terminal devices is lost
Solution Approach 1:
The scanner performs preliminary determination of the storage area type before uploading scan data. By checking whether the designated storage area is accessible via multiple access methods or only a single access method in advance, the scanner prevents uploading to incompatible areas, thereby ensuring both upload functionality and subsequent data accessibility from terminal devices.
2Ease of operation
If multiple access methods are supported for data storage server, then data accessibility is improved, but system complexity increases
Solution Approach 1:
The invention segments storage areas into two distinct types: those accessible by multiple access methods and those accessible by only a single access method. This segmentation allows the scanner to apply different upload strategies based on the storage area type, simplifying the overall system by avoiding unnecessary support for incompatible access methods while maintaining data accessibility where possible.
3Measurement precision
If long URLs are stored in memory, then access precision is maintained, but memory usage increases
Solution Approach 1:
The invention creates a shortened copy of the long URL and stores this abbreviated version in memory instead of the original long URL. The URL shortening service generates a compact representative form that preserves the essential access information while occupying significantly less memory space, thus maintaining access functionality while reducing memory consumption.

AI summary
A scanner may perform: determining whether a target area within a data storage server is in a first type of storage area or in a second type of storage area, the first type of storage area being a storage area in which uploaded data can be accessed by using whichever of a first and a second access method, and the second type of storage area being a storage area in which uploaded data can be accessed by using the first access method but not the second access method; uploading scan data in the target area in the first type of storage area in a case where it is determined that the target area is in the first type of storage area; and informing the user of impossible designation information in a case where it is determined that the target area is in the second storage area.
