Dynamic Buffer Allocation in Image Scanning Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in allocating appropriate storage areas in image scanning devices with multiple buffer areas, as existing technologies lack efficient mechanisms for managing and adjusting storage capacity based on usage status.
Innovation Solution
An image scanning device with a scanning unit, processing units, and a storage unit that includes an acquisition unit to monitor buffer usage status and a changing unit to dynamically adjust storage area allocation between buffer areas, facilitating improved performance without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple buffer areas are allocated in memory for different units, then image data transfer capability is improved, but storage area allocation becomes complex and difficult for users to manage
Solution Approach 1:
The system automatically monitors buffer usage status and performs storage area allocation adjustments without requiring user intervention. The control unit acts as a self-service mechanism that autonomously manages the complexity of multi-buffer allocation while maintaining improved data transfer capability
Solution Approach 2:
The system implements a feedback mechanism where the control unit continuously monitors the usage status of each buffer area and uses this information to dynamically adjust storage area allocation. This feedback loop enables automatic optimization of buffer distribution across multiple units without user involvement
2Productivity
If fixed storage area allocation is used for buffer areas, then device simplicity is maintained, but performance optimization based on usage status cannot be achieved
Solution Approach 1:
The system transitions from fixed storage allocation to dynamic allocation where buffer area sizes are automatically adjusted based on real-time usage status. This dynamic adaptation enables performance optimization while the control unit handles the automation of storage management without requiring user actions
