Dual Storage Architecture for Image Processing Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Composite image processing machines face challenges in reliability and functionality due to the use of large-capacity storage devices, which are prone to vibration and heat issues, making it difficult to store and run external applications post-shipment, leading to increased operational costs and user dissatisfaction.
Innovation Solution
The implementation of a dual storage configuration using a flash memory for existing applications and a hard disk drive for external applications, with a diagnostic process to ensure reliability, allowing for the installation and execution of external applications post-shipment, and user-controlled permission settings for starting applications from the hard disk drive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large-capacity storage device (HDD) is used to store external applications, then the functionality and adaptability of the image processing apparatus is improved, but the reliability deteriorates due to vibration and heat issues
Solution Approach 1:
The patent divides the storage system into two separate storage devices: a first storage device (ROM/flash memory) for storing essential firmware and existing applications, and a second storage device (HDD) for storing external applications. This segmentation allows the HDD to be used for expanding functionality while the essential system components remain on more reliable storage, thereby resolving the contradiction between functionality and reliability.
2Adaptability or versatility
If a large-capacity storage device is used to store external applications, then the adaptability is improved, but the ease of repair deteriorates as troubles require special staff intervention
Solution Approach 1:
The patent extracts external applications from the essential system firmware by storing them in a separate second storage device (HDD). This extraction allows troubles in the HDD to be handled independently from the core system, enabling easier repair and maintenance since the essential functions remain intact on the first storage device, reducing the need for special staff intervention.
3Reliability
If applications are stored in internal memory before shipment, then the reliability is maintained, but the ease of operation deteriorates as external applications cannot be added post-shipment
Solution Approach 1:
The patent introduces a dynamic storage architecture where the second storage device (HDD) can be dynamically loaded with external applications after shipment. The system can adaptively load applications from the HDD into memory during operation, providing both the reliability of pre-installed firmware and the operational flexibility to add new functions post-shipment.
4Adaptability or versatility
If a dual storage configuration is implemented, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements a universal storage management system where the control unit can selectively access and execute applications from either the first storage device or the second storage device based on runtime conditions. This multi-functional access mechanism allows the system to handle both essential firmware and external applications through a unified interface, reducing the perceived complexity despite the dual storage configuration.
Data Source
AI summary
A composite machine performs various types of image processing with executing relevant applications, wherein: upon starting an application stored in a hard disk drive, predetermined diagnosis processing is performed on the hard disk drive beforehand; and, upon starting an application stored in a flash memory, the application is startable independently from the predetermined diagnosis processing being performed on the hard disk drive.
