Image Processing Apparatus Destination Table Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatuses face issues with transfer errors when user authentication is not guaranteed, leading to incorrect transfer destinations due to reliance on built-in memory for destination tables, which can become outdated if not updated properly.
Innovation Solution
Implementing an image processing apparatus with a storage unit that separates common and personal destination tables, allowing users to set transfer destinations using the common table exclusively, ensuring that only authenticated users can access their personal table settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a destination table linked to user authentication is stored in built-in memory, then transfer operations can be performed, but the destination table may become outdated if not updated properly, leading to transfer errors
Solution Approach 1:
The destination table is segmented into two separate tables: a common destination table accessible by all users and a personal destination table accessible only by authenticated users. This segmentation resolves the contradiction by allowing the common table to provide stable, always-accessible destinations while the personal table handles user-specific destinations that require authentication, eliminating the need to manage updates for a single large table.
Solution Approach 2:
The control unit acts as an intermediary that manages the selection and switching between common and personal destination tables based on authentication status. When a user is not authenticated, the control unit ensures only common destinations are available, preventing transfer errors while maintaining system complexity through automated mediation rather than manual table management.
2Adaptability or versatility
If user authentication is required to access personal destination tables, then user-specific destinations can be managed, but transfer operations fail when users are not logged in
Solution Approach 1:
By dividing destinations into common and personal categories, the system allows unauthenticated users to access common destinations without authentication, maintaining ease of operation. Authenticated users gain additional access to personal destinations, providing adaptability. This segmentation resolves the contradiction by making authentication optional for common destinations while requiring it only for personal destinations.
Solution Approach 2:
The common destination table serves as a universal resource accessible by all users regardless of authentication status, while the personal destination table provides user-specific functionality. This multi-functionality resolves the contradiction by ensuring that core transfer operations remain available to all users through common destinations, while authenticated users enjoy enhanced capabilities through personal destinations.
3Productivity
If the common destination table is updated, then new destinations are available, but the built-in memory destination table may not be updated simultaneously, causing mismatches
Solution Approach 1:
The personal destination table is extracted from the built-in memory and stored in a separate storage unit. This extraction resolves the contradiction by allowing the common destination table in built-in memory to be updated independently and immediately, while personal destinations are managed separately. The control unit ensures consistency by loading personal destinations from storage when needed, eliminating synchronization issues between memory and storage.

AI summary
An image processing apparatus that transmits image data via a network, and a method of controlling the same, store a common destination table that users can reference commonly, and a personal destination table that a specific user can reference, and control so that when a transfer destination of image data in accordance with an operation of a user is set, the user can set the transfer destination by referencing the common destination table excluding the stored personal destination table.
