Solution Overview
Problem
Current disk drive fastening mechanisms on computer chassis require the use of screwdrivers for installation and removal, complicating the production process and reducing efficiency.
Innovation Solution
A disk drive fastening mechanism that includes a computer chassis with a top cover and base, featuring a first disk drive rack with retaining sets and a second disk drive rack that can be slid into place without tools, using elastic wedge members and detent sections to secure the disk drives in multiple dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw fastening is used to secure disk drives on computer chassis, then reliable fastening is achieved, but assembly complexity and time increase due to requiring screwdrivers
Solution Approach 1:
The retaining set includes elastic wedge members that automatically engage with detent sections on the disk drive rack, enabling self-fastening without external tools. The elastic deformation of the wedge members provides both the fastening action and the locking mechanism, allowing the disk drive to secure itself to the chassis.
Solution Approach 2:
The patent replaces the traditional screw-threaded fastening system with an elastic wedge-detent mechanical system. The elastic wedge members deform elastically to engage with detent sections, providing fastening through elastic deformation rather than threaded engagement, thereby eliminating the need for screwdrivers.
2Reliability
If screw fastening is used to secure disk drives on computer chassis, then secure fastening is achieved, but assembly time increases
Solution Approach 1:
The retaining set includes elastic wedge members that automatically engage with detent sections on the disk drive rack, enabling self-fastening without external tools. The elastic deformation of the wedge members provides both the fastening action and the locking mechanism, allowing the disk drive to secure itself to the chassis.
Solution Approach 2:
The elastic wedge members are pre-positioned in the retaining set to automatically engage with corresponding detent sections when the disk drive rack is inserted. This preliminary positioning enables rapid assembly without requiring manual screw fastening operations.
3Ease of operation
If manual latching mechanisms are used to fasten disk drives without tools, then assembly simplicity is improved, but fastening reliability may be compromised
Solution Approach 1:
The elastic wedge members utilize curved surfaces that guide engagement with the detent sections. The curved geometry ensures proper alignment and smooth engagement, while the elastic deformation provides the necessary force for reliable locking without requiring complex multi-component mechanisms.

AI summary
A disk drive fastening mechanism includes a computer chassis, a first disk drive rack and a second disk drive rack. The computer chassis has a top cover and a base that are connectable to each other. The first disk drive rack including a first retaining set and second retaining set is located on the base for housing a first disk drive. The second disk drive rack is movably mounted onto the top surface of the first disk drive rack for housing a second disk drive, confined in the first dimension and second dimension by the first retaining set and the second retaining set, and confined in the third dimension by the top cover and the first disk drive rack. Hence the second disk drive can be installed on the computer chassis without using tools so as to save installation time and simplify operation.
