Engineering Contradiction Analysis
1Quantity of substance
If multiple hard disks operate simultaneously to increase storage capacity, then the storage capacity is improved, but vibrations generated by hard disk operations and interference between adjacent operating hard disks adversely affect the overall performance
Solution Approach 1:
The system pre-establishes performance information for multiple hard disks under different read/write operation settings before actual operations occur. This preliminary characterization of disk performance under various conditions enables the controller to make informed decisions about disk selection and operation configuration, thereby optimizing performance while managing vibrations and interference effects.
Solution Approach 2:
The system changes operational parameters by selecting different read/write operation settings and configuring which hard disks to use based on pre-established performance information. This dynamic parameter adjustment allows the system to adapt to vibration and interference conditions, optimizing the balance between storage capacity utilization and operational performance.
2Object-affected harmful factors
If anti-vibration mechanisms are implemented to reduce vibrations from system fans and hard disk operations, then the adverse effects of vibrations are reduced, but the device complexity increases
Solution Approach 1:
The system replaces mechanical anti-vibration mechanisms with a software-based solution. Instead of using physical dampers, isolators, or other mechanical components to reduce vibrations, the system uses intelligent algorithms that pre-establish performance information and dynamically configure hard disk operations to minimize the impact of vibrations and interference, thereby reducing device complexity while maintaining performance.
Solution Approach 2:
The system performs self-optimization by automatically configuring hard disk operations based on pre-established performance information without requiring external anti-vibration mechanisms. The controller autonomously decides which hard disks to use and how to configure read/write operations to minimize vibration and interference effects, eliminating the need for additional mechanical components.
3Productivity
If read/write operations are optimized by selecting specific hard disks based on performance information, then the overall performance is enhanced, but the control complexity increases
Solution Approach 1:
The system pre-establishes performance information for all hard disks under various read/write operation settings before runtime. This preliminary work includes characterizing disk performance, vibration characteristics, and interference patterns, storing this information for quick retrieval during operation. This upfront preparation simplifies real-time control decisions while achieving performance optimization.
Solution Approach 2:
The system creates a virtual model of hard disk performance characteristics by pre-establishing performance information that captures the behavior of physical disks under different conditions. This virtual performance model allows the controller to simulate and evaluate different operation configurations without complex real-time measurements, simplifying the control process while maintaining optimization capability.

AI summary
A method for managing read/write (R/W) operations on an electronic device with hard disks, includes: upon receipt of R/W operation information related to an intended R/W operation, configuring a processor to decide which of the hard disks will be read/written with reference to the R/W operation information and sets of pre-established performance information. The sets respectively correspond to R/W operation settings. Each set includes multiple pieces of information each containing a performance indication related to a corresponding one of candidate combinations of the hard disks under the corresponding R/W operation setting. The decision is made with reference to the set, the R/W operation setting corresponding to which matches the R/W operation information.
