Communication Device Automatic Preview Scanning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication devices and copy machines require users to manually initiate a preview process for each sheet of an original, leading to user unfriendliness and potential wasteful communications due to the need for multiple operations.
Innovation Solution
A communication device with an image data generating unit, a preview data generating unit, and a transmitting unit that allows for automatic scanning and previewing of an entire original before transmitting scanned data, enabling users to select a mode for displaying image data after the entire original is read or after each page is read, facilitating efficient data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the copy machine waits for user instruction to execute preview process, then the device complexity is reduced, but the ease of operation deteriorates because the user must input command each time one sheet is scanned
Solution Approach 1:
The system performs preliminary actions by automatically executing the preview process after scanning each sheet without waiting for user commands. The control unit automatically determines when to display preview images based on scan completion events, eliminating the need for manual intervention while maintaining manageable system complexity through event-driven architecture.
Solution Approach 2:
The copy machine performs self-service by automatically initiating and managing the preview process based on scan completion events. The system monitors its own state through the scanning unit and autonomously decides when to display previews, removing the burden of manual operation while keeping the control logic contained within the device's existing framework.
2Loss of time
If the user views image data for each sheet manually, then the loss of information is reduced, but the loss of time increases due to multiple operations required
Solution Approach 1:
The system performs preliminary review actions by automatically displaying preview images of scanned sheets in sequence before the user finalizes the scanning process. This allows the user to review each sheet's image data immediately after scanning without requiring multiple separate operations, thereby reducing time loss while maintaining complete information review through the sequential display mechanism.
Solution Approach 2:
The preview process maintains continuity by automatically proceeding through each scanned sheet in sequence without interruption. The control unit continuously monitors scan completion events and displays previews without requiring the user to restart or re-initiate the review process, ensuring continuous and efficient information verification while minimizing operational repetitions.
3Productivity
If the copy machine scans and accumulates image data before printing, then the productivity is improved, but the loss of time increases when user needs to rescan pages
Solution Approach 1:
The system performs preliminary scanning and accumulation of image data for all sheets before the user initiates the printing process. The control unit automatically manages the scanning sequence and stores image data in memory, allowing the user to review previews and make corrections without repeating the entire scanning process, thereby maintaining high productivity while minimizing time loss through efficient data management.
Solution Approach 2:
The system implements feedback by displaying preview images of scanned sheets and allowing the user to indicate when scanning is complete or when rescan is needed. Based on this feedback, the control unit intelligently manages the scanning and accumulation process, preventing redundant scanning operations and optimizing the workflow between scanning, review, and printing stages.
Data Source
AI summary
An image data is generated by scanning an original. The image data is converted and stored into a RAM. Preview data is generated from the converted data and then displayed on a display unit. When a transmission command is received after the display unit displays the display data, the converted data is transmitted to a prescribed destination.
