Solution Overview
Problem
Server racks lack efficient mechanisms for hot-swappable hard drives, leading to difficulties in convenient installation and maintenance, particularly in ensuring continuous data connectivity and power supply during drive replacement.
Innovation Solution
The server rack design incorporates slide rails with a resiliently wound ring and cable system that maintains electrical connection during drive insertion and removal, using an adapter plate with internal threads and a connecting device to secure the slide rail module, ensuring uninterrupted power and data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If slide rails are equipped for hard drive insertion and removal, then ease of operation is improved, but maintaining continuous electrical connection during drive replacement becomes difficult
Solution Approach 1:
The patent introduces a resiliently wound ring as an intermediary component between the slide rail and the hard drive. This ring maintains continuous electrical connection during drive replacement by flexing and deforming elastically as the drive is inserted or removed, allowing the drive to move in and out while keeping the electrical contact intact throughout the operation.
Solution Approach 2:
The patent applies dynamics by making the electrical connection component (the resiliently wound ring) flexible rather than rigid. The ring can dynamically adjust its shape and position during the hot-swapping process, maintaining electrical contact even as the hard drive moves along the slide rail, thus enabling continuous connection during dynamic operation.
2Productivity
If hot-swappable hard drives are implemented, then productivity is improved, but device complexity increases due to additional connection mechanisms
Solution Approach 1:
The patent uses a resiliently wound ring, which is a flexible component, to maintain electrical connection during hot-swapping operations. This flexible ring simplifies the overall mechanism compared to rigid connection systems with multiple switches or connectors, as it naturally flexes to accommodate drive movement while maintaining continuous contact.
Solution Approach 2:
The resiliently wound ring automatically adjusts and maintains electrical connection during the hot-swapping process without requiring additional control mechanisms. The elastic deformation of the ring itself provides the necessary connection maintenance, making the system self-regulating and reducing overall device complexity.

Data Source
AI summary
A server rack able to maintain electrical connections to its components during replacements includes a shell and brackets for data storage devices. The data storage devices are electrically connected to the bracket. The shell includes a power supply module and a connecting device electrically connected to the power supply module. The connecting device includes a resilient ring and a cable, one end of the cable is secured on the resilient ring, and the other end of the cable is electrically connected to the bracket. When the bracket is slid in the shell, the resilient ring elastically deforms to release cable or take back the slack cable, to maintain the electrical connections at all times.
