Scanning Apparatus Automatic Page Replacement Preview
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scanning apparatuses require tedious and inconvenient processes for replacing incorrect pages, involving rescanning and editing, which leads to waste of resources and user effort, especially when outputting multi-page documents like PDF files.
Innovation Solution
A scanning apparatus with automatic content replacement capabilities, featuring an image capturing unit, storage unit, control unit, and output module, allowing for detection and replacement of pages during the preview stage using a sensor and automatic feeding, eliminating the need for rescanning and editing software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional scanning apparatus outputs multi-page content and displays it on screen, then the scanned content can be viewed, but if a page needs replacement, the whole pages must be rescanned and reedited on computer, which increases loss of time and device complexity
Solution Approach 1:
The scanning apparatus performs preliminary actions by keeping all scanned pages stored in the storage unit and ready for replacement before the user actually needs to replace a page. When a user wants to replace a page, the system can immediately retrieve the previously scanned pages and integrate the new page without requiring rescanning of surrounding pages.
Solution Approach 2:
The system creates a digital copy of the scanned pages in the storage unit, allowing the user to replace individual pages by copying only the necessary new page content while preserving other pages. This eliminates the need to rescane entire documents and enables selective page replacement through digital manipulation.
2Ease of operation
If conventional scanning apparatus requires computer editor software to insert updated pages, then page replacement can be achieved, but it increases device complexity and requires additional paid software
Solution Approach 1:
The scanning apparatus merges the scanning function, storage function, and page replacement function into a single integrated system. The control unit coordinates the image capturing unit, storage unit, and display device to enable page replacement directly within the scanning apparatus, eliminating the need for separate computer editor software.
Solution Approach 2:
The scanning apparatus is designed with multi-functionality, serving as both a scanning device and a page replacement system. The storage unit stores page images, the display device shows them, and the control unit manages replacement operations, making the scanning apparatus a universal device that handles both scanning and document assembly tasks.
3Productivity
If conventional scanning apparatus sends outputted content to printer or copy machine, then printing can be performed, but waste of papers and toner is unavoidable when replacement of correct pages is carried out
Solution Approach 1:
The system performs preliminary display and page replacement operations on the screen before sending the final document to the printer. Users can review and replace pages in the digital preview stage, ensuring the document is correct before physical printing occurs, thereby preventing waste of paper and toner from printing incorrect versions.
Solution Approach 2:
The system works with digital copies of pages in the storage unit during the preview and replacement phase. All modifications are made to these digital copies on the display device, and only the final corrected version is sent to the printer. This digital copying and manipulation process eliminates the need to print multiple versions for review and replacement.

AI summary
When an original is scanned by a scanning apparatus and the corresponding one or more page images are generated and temporarily stored in a storage unit of the scanning apparatus, these page images are sent to a display device for preview. As a new replacement sheet is detected by the scanning apparatus when one of the page images is currently previewed on the screen of the display device, the page image stored in the storage unit and currently previewed on the screen is replaced by a new page image of the replacement sheet. Finally, all the page images temporarily stored in the storage unit are outputted as an output file.
