Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in managing the output size of scanned documents, as existing solutions require users to reprocess scans or adjust settings without clear understanding of their impact, leading to oversized files.
Innovation Solution
A method and system for a multi-function device that automatically determines optimal scan settings in real-time, displaying output file size to users and adjusting settings based on user input to manage the output size of scanned files, using techniques like JPEG quantization and different compression algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If scan settings are adjusted to reduce output file size, then file size is reduced, but image quality deteriorates
Solution Approach 1:
The system dynamically adjusts scan settings during the scanning process based on real-time monitoring of file size. Instead of using fixed settings, the controller modifies resolution, color type, and compression parameters adaptively to maintain quality while controlling file size growth.
Solution Approach 2:
The system implements real-time feedback by monitoring the output file size during scanning and using this information to adjust scan settings. The controller receives feedback on current file size and modifies subsequent scanning parameters to keep the file size within acceptable limits while preserving image quality.
2Ease of operation
If user is provided with scan setting options, then user can adjust settings, but user understanding of setting impact is insufficient leading to suboptimal results
Solution Approach 1:
The system performs self-service by automatically determining and adjusting optimal scan settings without requiring user expertise. The controller analyzes the document being scanned and autonomously selects appropriate resolution, color type, and compression parameters, eliminating the need for users to understand technical scan settings.
Solution Approach 2:
The system automatically changes scan parameters (resolution, color type, compression) based on real-time analysis of the scanning process and file size monitoring. This eliminates the need for users to manually adjust parameters and understand their impact.
3Productivity
If scanning continues without monitoring file size, then scanning process is simple, but output file size exceeds requirements
Solution Approach 1:
The system maintains continuous monitoring of file size throughout the scanning process without interrupting or slowing down the scanning operation. The controller continuously tracks file size growth and makes real-time adjustments to keep scanning productive while ensuring file size requirements are met.
Solution Approach 2:
Real-time feedback on file size is provided to the controller during scanning, enabling dynamic adjustment of scan parameters to control file size while maintaining scanning productivity. The system uses this feedback loop to balance speed and file size control.

AI summary
The present disclosure discloses methods and systems for automatically determining one or more optimal scan settings to manage an output size of a document submitted for scanning at a multi-function device. The method includes receiving the document for scanning from a user, wherein the document includes one or more pages having content. As scanning activity is progressed at the multi-function device, an output file size is displayed to the user via a user interface in real-time. Then, an input from the user is received on the displayed output file size. Based on the input from the user, one or more scan settings are determined to be applied on the already scanned pages and remaining pages of the document to be scanned, to manage the output size of an output scanned file to be generated. Thereafter, the determined one or more scan settings are applied such that the output size of the scanned file is in accordance with the requirement. Finally, the scanned file is output of the required size.
