Dynamic Storage Period Setting for Print Job Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing apparatuses face limitations in utilizing the storage capacity of external storage devices when connected, as the upper limit of print job storage periods remains low, preventing efficient use of larger storage capacities.
Innovation Solution
The apparatus includes a reception unit for receiving print jobs, a storage unit for storing them in a first storage device, and a setting unit that sets a longer storage period for print jobs stored in a second storage device with a larger capacity, allowing efficient utilization of the extended storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a print job storage period is set to prevent storage area overflow, then the storage capacity is protected, but the storage period is limited and cannot be extended even when larger storage devices are available
Solution Approach 1:
The patent implements dynamic storage period settings that automatically adjust based on storage device capacity. When a second storage device with larger capacity is detected, the system dynamically extends the storage period from a first storage period to a second storage period, allowing the storage system to adapt its parameters based on available resources.
Solution Approach 2:
The system changes the storage period parameter based on the storage device being used. The setting unit configures different storage periods (first storage period for smaller devices, second storage period for larger devices) according to the detected storage capacity, optimizing the balance between storage utilization and data retention.
2Duration of action of moving object
If the storage period is extended to utilize larger storage capacity, then more print jobs can be retained, but the risk of storage area overflow increases
Solution Approach 1:
The detection unit continuously monitors the storage device connection status and capacity. Based on this feedback, the setting unit automatically adjusts the storage period configuration - extending it when larger storage is available and maintaining shorter periods when smaller storage is used, preventing overflow while maximizing capacity utilization.
3Ease of operation
If a fixed storage period is used for all storage devices, then the system is simple to manage, but the capacity of larger storage devices cannot be efficiently utilized
Solution Approach 1:
The system performs automatic detection and configuration without requiring manual intervention. The detection unit identifies the storage device capacity, and the setting unit automatically configures the appropriate storage period, enabling the system to self-optimize its performance based on the available hardware resources.

AI summary
When a second storage device having a storage capacity larger than a storage capacity of a first storage device is usable, a storage unit stores a received print job in the second storage device. When the second storage device having a storage capacity larger than a storage capacity of the first storage device is usable, a setting unit is able to set a second storage period longer than a first storage period as a storage period for the print job stored in the second storage device.
