A structure comprising a carrier and chassis with a rotatable handle and cam mechanism allows for easy connection and disconnection of HDDs, utilizing a U-shaped handle and frame with cam linkages and limiting components to securely mount and dismount HDDs, enhancing installation and removal efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If more HDDs are placed in limited computing device space, then data storage capacity increases, but installation and removal operations become more difficult and time-consuming
Solution Approach 1:
The mounting structure is segmented into a carrier component and a chassis component that can be independently manipulated. The carrier holds the HDD while the chassis provides mounting slots, allowing the HDD to be installed or removed as a complete unit rather than individually securing each drive, thus simplifying operations despite increased storage capacity
Solution Approach 2:
The mounting structure incorporates movable components including a handle that can be rotated between locked and unlocked positions, and a cam mechanism that transitions between engaged and disengaged states. This dynamic design enables quick transition between secure mounting and easy removal, facilitating efficient HDD replacement operations
2Reliability
If traditional mounting structures are used, then device stability is maintained, but maintenance and replacement time increases
Solution Approach 1:
The cam mechanism is pre-configured in the mounting structure to automatically engage with the carrier when the handle is rotated to the locked position. This preliminary arrangement of components ensures that stability is achieved automatically through the mechanical design, eliminating the need for time-consuming manual alignment or multiple fastening operations during maintenance
Solution Approach 2:
The cam mechanism acts as an intermediary between the handle operation and the carrier-chassis connection. Rotating the handle drives the cam to engage with the carrier, translating a simple rotational motion into secure mechanical engagement, thus reducing maintenance time while maintaining device stability
3Quantity of substance
If multiple HDDs are installed in constrained spaces, then storage capacity increases, but the complexity of installation procedures increases
Solution Approach 1:
The carrier-chassis mounting structure is designed as a universal interface that can accommodate multiple HDDs of the same form factor. The standardized design with consistent cam mechanisms and carrier slots allows the same installation procedure to be replicated for each drive, reducing procedural complexity despite installing multiple drives in constrained space

AI summary
A structure for mounting a storage device to a server and providing a fast installation and removal of a storage device includes a carrier and a chassis. The carrier includes a rotatable handle with a cam on the axis of rotation and a frame. The cam is connected to the frame. The chassis includes an immovable limiting component. With the carrier mounted in the chassis, rotation of the handle clockwise or counterclockwise pushes the carrier to move, to lock or unlock the carrier because of the limiting component resting against the cam. The structure greatly improves the convenience of the installation and removal of the storage device. A computing device is also disclosed.
