MFP Controller Adapts Function Selection to File Attributes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital multifunction devices lack the knowledge to determine appropriate functions for processing document data files, leading to difficulty in performing desired operations and potential misuse of functions.
Innovation Solution
An image forming apparatus with an input device, display, and controller that reads file attributes to determine available functions and presents a screen for executing the appropriate process, allowing users to perform specified processing without adequate knowledge and enabling managers to restrict file access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users are provided with multiple functions for processing document data files, then the versatility and capability of the device is improved, but the ease of operation deteriorates because users lack the knowledge to determine which function to select
Solution Approach 1:
The system automatically reads file attributes and determines appropriate functions without requiring user knowledge. The controller performs self-service by autonomously analyzing the document data file's attributes and selecting suitable processing functions, eliminating the need for users to understand complex function selections.
Solution Approach 2:
The system provides feedback to users by displaying only the functions that are appropriate for the specific file being processed. Based on the file attributes read by the controller, the system feedbacks a customized function list to the display unit, helping users make informed selections without needing prior knowledge of all available functions.
2Loss of information
If the system provides all available functions to users, then the completeness of information is improved, but the device complexity increases making it harder for users to navigate and select appropriate functions
Solution Approach 1:
The system extracts and displays only the relevant functions based on file attributes. Instead of showing all available functions, the controller reads the file's attributes and extracts only those functions that are appropriate for the specific file type and security settings, reducing interface complexity while maintaining information completeness for relevant operations.
Solution Approach 2:
The system applies local quality by providing different function sets to different users based on their authentication levels and the specific file being processed. Each user sees a customized list of functions appropriate to their credentials and the file's attributes, rather than a uniform complex list for all users.
3Adaptability or versatility
If users can select any function for processing files, then the flexibility of the system is improved, but security and proper function usage deteriorate because users may select inappropriate functions
Solution Approach 1:
The system performs preliminary action by reading file attributes and determining appropriate functions before the user makes a selection. The controller analyzes the document data file's attributes in advance and pre-determines which functions are suitable, ensuring that users can only select from pre-validated appropriate functions rather than any arbitrary function.
Solution Approach 2:
The controller acts as an intermediary between the user and the function selection process. Instead of allowing direct selection from all available functions, the controller mediates by filtering and presenting only appropriate functions based on file attributes, ensuring proper function usage while maintaining user flexibility.

AI summary
In the case where an attribute of a general-purpose file to be processed is an attribute inhibiting printing, an MFP selects a transmission function, which is one of output functions of the MFP, as a function that can be performed (selected) in response to an output instruction, and displays a screen for transmission. In the case of an attribute permitting a document assembly function, the MFP determines that a bind function is a function that can be performed (selected), and displays a screen for the function. In the case of an attribute inhibiting the document assembly function, the MFP determines that a function of adding information to a file, which is one of the output functions of the MFP that does not implement the document assembly function, is a function that can be performed (selected), and displays a screen for the function.
