Hard Disk Triggering Mechanism for Automatic Power Off
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hot swap technologies for data storage devices require users to operate the system's operation system to control electric current, making it inconvenient for removing peripheral devices like hard disks from servers.
Innovation Solution
A hard disk module with a triggering mechanism that allows the hard disk to power off automatically by moving a triggering rod to trigger a switch, facilitating hot plugging without the need to operate the system's operation system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user operates the operation system to control electric current for hot swap, then the system reliability is maintained, but the ease of operation deteriorates
Solution Approach 1:
The hard disk drive is designed with self-service capabilities through the triggering mechanism that automatically controls power supply cutting. When the fixing device detects the hard disk removal, it automatically triggers the power off sequence without requiring user interaction with the operation system, making the system serve itself during the hot swap process
Solution Approach 2:
A triggering mechanism acts as an intermediary between the fixing device and the power supply system. This intermediary component (triggering rod connected to switch) translates the physical removal action into an automatic power control signal, eliminating the need for direct user interaction with the operation system while maintaining reliable power management
2Ease of operation
If the triggering mechanism is added to enable automatic power off, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The triggering mechanism is segmented into distinct functional components: the triggering rod for mechanical input, the switch for electrical control, and the connection mechanism. This segmentation allows each component to perform its specific function efficiently while keeping the overall design modular and manageable, reducing the perceived complexity
Solution Approach 2:
The triggering mechanism merges the power control function with the physical removal action. The same mechanical movement that removes the hard disk from the fixing device also triggers the power off sequence through the connected rod and switch, combining multiple functions into a single integrated mechanism rather than separate systems

AI summary
A hard disk, a fixing device, and a hard disk module are provided. The hard disk includes a base shell, a main circuit board mounted on the base shell, a switch mounted on the main circuit board, and a triggering mechanism. The triggering mechanism includes a triggering rod. The triggering rod is slidably arranged on the base shell along a first direction. The triggering rod can move in the first direction to trigger the switch, thereby causing the main circuit board to power off the hard disk;
