Distributed Backup Power Supplies for Storage Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional storage devices require a large, fixed backup power supply that occupies significant space and is inefficient for devices with low power consumption, leading to energy waste and inflexible configuration options.
Innovation Solution
The implementation of multiple small backup power supplies that can be arranged flexibly within the storage device, with each supply dedicated to specific components, allowing for distributed power distribution and customizable capacities to reduce overall battery requirements and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large backup power supply is used to ensure data protection during power failures, then reliability is improved, but the device occupies significant space and increases in complexity
Solution Approach 1:
The patent divides the backup power supply system into multiple independent power supply modules, each capable of protecting specific components. Instead of using one large backup power supply, the system employs several smaller modules distributed throughout the storage device, reducing overall complexity while maintaining reliability through distributed protection.
2Reliability
If a large backup power supply is arranged in the storage device to prevent data loss, then reliability is improved, but the space occupied by the device increases
Solution Approach 1:
The backup power supply is segmented into multiple smaller modules that can be distributed throughout the storage device. Each module protects specific components locally, reducing the need for a single large power supply and optimizing space utilization while maintaining data protection capabilities.
3Reliability
If a single large backup power supply is used, then power protection is ensured, but energy efficiency decreases for low power consumption devices
Solution Approach 1:
Different power supply modules are assigned to different components based on their power consumption characteristics and criticality. Low power consumption components receive protection from smaller local modules, while high power components receive protection from larger modules. This local quality approach ensures that each component receives appropriate protection without unnecessary energy waste from oversized power supplies.
