Disk Drive Transporter Vibration Isolation Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current disk drive testing systems face challenges with vibration-induced errors and inefficiencies due to the need for serial or batch testing, which affects the reliability of test results and increases manufacturing costs, especially with newer, more sensitive disk drives.
Innovation Solution
Implementing an automated transporter system, such as a robotic arm or gantry system, to retrieve and deliver multiple disk drives to test slots efficiently, using a manipulator with V-shaped connectors to securely attach and transfer disk drives, allowing for bulk feeding and continuous testing with minimal user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual handling or robotic arm is used to transfer disk drives, then the testing system can operate, but vibration is introduced affecting test reliability
Solution Approach 1:
The patent introduces a vibration isolation table as an intermediary platform between the automated transporter and the disk drive testing system. This table absorbs and isolates vibrations generated by the transporter, preventing them from reaching the disk drives during testing. The table acts as a mediator that decouples the vibration source from the sensitive testing equipment, thereby maintaining test reliability while enabling automated operation.
2Productivity
If automated transporter is implemented, then productivity increases, but system complexity increases
Solution Approach 1:
The patent divides the automated testing system into distinct modular components: a vibration isolation table, a test system module, and an automated transporter module. Each component can be independently designed, tested, and maintained. This segmentation reduces overall system complexity by allowing parallel development and troubleshooting of individual modules while maintaining high automated testing throughput.
3Productivity
If disk drives are tested in batches, then manufacturing efficiency improves, but vibration cross-talking between adjacent units increases
Solution Approach 1:
The vibration isolation table serves as a mediator between multiple disk drives tested in parallel batches. By placing each drive on the vibration-isolated table during testing, the system prevents vibration cross-talking between adjacent drives while maintaining batch testing efficiency. This allows manufacturers to test multiple drives simultaneously without the harmful vibration interference that would otherwise occur.

AI summary
A method of transferring disk drives within a disk drive testing system includes actuating an automated transporter to retrieve multiple disk drives presented for testing, and actuating the automated transporter to deliver each retrieved disk drive to a respective test slot of the disk drive testing system and insert each disk drive in the respective test slot.
