Touch Display Module Preview for Office Apparatus Scanning Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of office apparatuses with automatic document feeders often face confusion about which side of a document to scan, leading to potential blank or wrong printing pages, as the error is only detected after the entire document is copied, wasting time and resources.
Innovation Solution
A touch display module with a control unit that allows users to preview and select which side of a scanned object to copy by displaying patterns corresponding to scanned images, enabling the printing module to print the correct side or both sides of a document, preventing errors during the copying process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic document feeder is used to copy large number of documents, then scanning efficiency is improved, but user confusion about document orientation occurs leading to blank or wrong printing pages
Solution Approach 1:
The system displays a preview image of the scanned document on the touch display panel, providing visual feedback to the user about the document orientation and content before printing. This allows the user to confirm the correct side is being copied, preventing blank or wrong printing pages while maintaining efficient batch scanning through automatic document feeder.
2Device complexity
If user cannot preview scanned images before printing, then device complexity is reduced, but detection of printing errors is delayed until after completion
Solution Approach 1:
The system performs preliminary display of the scanned image on the touch display panel before the printing operation is executed. This preliminary action allows the user to detect potential errors in document orientation or content before wasting time and resources on incorrect printing, while adding minimal complexity to the overall system.
3Measurement precision
If touch display panel displays full-resolution scanned images, then image quality is improved, but display processing time and memory usage increase
Solution Approach 1:
The touch display panel displays a thumbnail or reduced-resolution preview of the scanned image, providing sufficient visual information for the user to confirm document orientation and content. This local quality approach maintains adequate image quality for verification purposes while significantly reducing display processing time and memory usage compared to displaying full-resolution images.

AI summary
A touch display module is for controlling a printing module and a scanning module. The scanning module is for at least scanning a first side of a scanned object to generate a first image corresponding to the first side of the scanned object. The touch display module includes a touch display panel and a control unit. The touch display panel at least includes a first section for displaying a first pattern corresponding to the first image and generating a first touch signal. The control unit controls the first section to display the first pattern corresponding to the first image when the control unit receives the first image transmitted from the scanning module. The control unit controls the printing module to print the first image according to the first touch signal when the control unit receives the first touch signal transmitted from the first section.
