Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image forming apparatuses, such as copiers, printers, and scanners, lack an efficient method to enhance their information processing environment by utilizing connected storage devices, limiting their ability to access and store information effectively across different systems.
Innovation Solution
The image forming apparatus functions as a client in a distributed file system, allowing it to access and store information on a server's file system, enabling improved information processing by mounting the server's file system and launching programs stored on the server, thereby enhancing the execution environment for information processing tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image forming apparatus uses only its own internal storage, then the storage access is fast and reliable, but the information processing environment is limited and cannot utilize external storage resources
Solution Approach 1:
The patent introduces a file management program as an intermediary that handles storage operations between the image forming apparatus and external storage devices. This program translates internal storage requests into appropriate external storage operations, enabling the apparatus to utilize external storage resources while maintaining a simplified interface for applications. The intermediary resolves the contradiction by abstracting the complexity of external storage access.
Solution Approach 2:
The image forming apparatus is enhanced with multi-functional storage capabilities, allowing it to operate with both internal and external storage devices. The system can selectively use different storage devices based on requirements, making the storage subsystem universal and adaptable to various configurations. This resolves the contradiction by enabling versatile information processing environments without requiring complex dedicated hardware for each storage type.
2Quantity of substance
If the image forming apparatus connects to external storage devices, then the storage capacity and information processing capabilities are enhanced, but the system complexity and difficulty of managing multiple storage devices increase
Solution Approach 1:
The patent merges multiple storage devices (internal and external) into a unified storage management system. The file management program presents a consolidated view of all storage devices to applications, allowing them to access any storage device through a common interface. This combining approach enables the system to utilize large storage capacities from multiple devices while reducing management complexity through unification.
Solution Approach 2:
The file management program implements self-service functionality by automatically managing storage operations, including file placement, retrieval, and device selection. The system autonomously handles the complexity of coordinating multiple storage devices without requiring manual intervention or complex configuration, thereby enabling enhanced storage capacity while keeping the management system simple.
3Adaptability or versatility
If the image forming apparatus mounts the server's file system, then access to external information processing resources is enabled, but the reliability and speed of local access may be reduced
Solution Approach 1:
The patent implements a dynamic storage access mechanism that can switch between local and remote file system access based on operational requirements. The system dynamically determines whether to use the mounted server file system or the local file system for each operation, optimizing both adaptability and reliability. This dynamic approach allows the apparatus to leverage external resources when needed while maintaining reliable local access for critical operations.
