Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional storage systems require manual and burdensome sequential power starting of extension devices, leading to operational inefficiencies and potential errors in starting order, which can result in the storage system not operating normally.
Innovation Solution
A storage device with a power supply unit, communication control unit, detecting unit, and power supply instructing unit that utilize a standby power source to automatically detect the progression of an initializing sequence and instruct power supply based on detection, ensuring proper starting order without operator error.

Engineering Contradiction Analysis
1Reliability
If manual sequential power starting is implemented, then the starting order can be controlled, but the operator burden increases significantly
Solution Approach 1:
The extension device autonomously determines its own starting时机 by detecting the initializing sequence stage from the superior device, and automatically controls its power supply without operator intervention. The device serves itself by monitoring communication protocols and triggering power supply independently.
Solution Approach 2:
The detecting unit continuously monitors the initializing sequence communication between the superior device and interface, detecting when the sequence has progressed to the given stage. This feedback mechanism triggers the power supply instructing unit to activate power supply at the appropriate时机, ensuring correct starting order.
2Ease of operation
If automatic power supply is implemented based on storage medium position, then operator burden is reduced, but the starting order may be incorrect
Solution Approach 1:
Instead of relying on preset positions, the system uses real-time feedback from the initializing sequence detection. The detecting unit monitors actual communication status between devices, ensuring power supply is triggered only when the superior device has properly initialized, guaranteeing correct starting order regardless of physical position.
Solution Approach 2:
The patent replaces the mechanical/physical positioning-based power supply control with an electronic communication-based control system. The detecting unit uses electrical communication signals from the initializing sequence to determine starting时机, substituting physical position detection with electronic state detection.
3Quantity of substance
If multiple extension devices are connected, then storage capacity increases, but the complexity of manual starting increases
Solution Approach 1:
Each extension device independently monitors the initializing sequence from the superior device and autonomously controls its own power supply timing. This self-service mechanism eliminates the need for operators to manually manage multiple devices, allowing unlimited extension devices to be connected without increasing operational complexity.
Solution Approach 2:
The patent divides the power supply control function into independent segments for each extension device. Each device has its own detecting unit and power supply control, allowing parallel operation and independent initialization. This segmentation enables multiple devices to be managed simultaneously without increasing overall system complexity.

AI summary
An OOB sequence monitoring unit detects that an OOB sequence carried out between a base device as a superior device and a connection I/F which operates even if an extension device is in a standby state has proceeded to a given stage. Based on the detection by the OOB sequence monitoring unit, a power supply control unit instructs a starting power supply unit to supply power. When the extension device starts, the OOB sequence is carried out between the extension device and the connection I/F of another extension device in the same manner. As a result, extension devices are started in decreasing order from the extension device closest to the superior device.
