Resolution Redefinition Control for Multi-Function Device Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-function computer peripheral devices face inefficiencies due to user-inputted resolutions that are either too high or too low for specific functions, leading to slowed operations and increased memory usage, as existing control systems do not effectively redefine resolution quality for combined scanning and printing functions.
Innovation Solution
A resolution quality redefinition control system, implemented in firmware or dedicated logic, communicates with user input panels and device engines to adjust scan and print resolutions based on user inputs, redefining them to optimal or efficient levels within the device's capabilities, ensuring acceptable output quality and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a user inputs a designated resolution higher than the optimal resolution for a specific function, then the output quality may be improved, but the operation speed decreases and memory usage increases
Solution Approach 1:
The control system dynamically changes the resolution parameter based on the selected function. When a user selects a function like faxing that has optimal resolution requirements, the system automatically adjusts the scan resolution to match the optimal value for that function, preventing unnecessarily high resolutions from being applied. This resolves the contradiction by ensuring output quality is sufficient without being excessive, thereby maintaining operation speed.
2Manufacturing precision
If a user inputs a designated resolution higher than the optimal resolution for a specific function, then the output quality may be improved, but the memory space required increases
Solution Approach 1:
The system automatically adjusts the scan resolution parameter to match the optimal resolution for the selected function. By preventing users from inputting resolutions higher than necessary for the chosen function, the system reduces the amount of image data that needs to be stored in memory during processing, thereby reducing memory space requirements while maintaining sufficient output quality.
3Productivity
If a user inputs a designated resolution lower than the optimal resolution for a specific function, then the operation speed increases and memory usage decreases, but the output quality becomes unacceptable
Solution Approach 1:
The control system provides feedback to the user when the designated resolution is lower than the optimal resolution for the selected function. The system compares the user-inputted resolution with the optimal resolution for the chosen function and notifies the user of the potential quality issue, allowing the user to adjust the resolution setting to achieve acceptable output quality.
4Adaptability or versatility
If the control system provides multiple resolution quality options for each function, then the adaptability to user needs improves, but the device complexity increases
Solution Approach 1:
The control system manages multiple resolution quality options by automatically selecting the appropriate resolution parameter based on the selected function. This automation reduces the complexity of manual resolution selection for users while maintaining adaptability to different function requirements. The system handles the complexity internally by mapping each function to its optimal resolution parameters.

AI summary
A resolution quality redefinition control system for a multi function scanner/printer controls a plurality of functions executable such as scanning, printing, copying and faxing. Multiple resolution qualities may be selected by a user for any of the functions through a user input in communication with the controller. A designated quality resolution may not be appropriate for a designated function, however. Some of the functions have an optimal resolution and/or a significant range of resolutions. When the designated quality resolution is not appropriate for a designated function, the controller re-defines the designated quality resolution as an execute resolution for each execution of one of the functions. The execute resolution may be a higher one of the multiple designatable resolutions when the designated resolution is below the optimal resolution but within said significant range, may be a lower of the multiple designatable resolutions when the designated resolution is above the optimal resolution but within said significant range, may be a maximum resolution, may be a minimum resolution or may be a single optimal resolution.
