Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of hard disk drives (HDDs) in servers is inefficient due to the need for fasteners like screws, which complicates the process and reduces efficiency.
Innovation Solution
A carrier unit with a bracket and carrier design that allows for tool-free, screw-less installation and removal of HDDs using a rotating handle and latching mechanism, enabling quick assembly and disassembly by rotating arms and an elastic latching system, eliminating the need for tools or power-assisted structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws and fasteners are used to install HDDs, then the connection stability is improved, but the installation efficiency deteriorates
Solution Approach 1:
The patent extracts and eliminates the screws and fasteners from the HDD installation process, replacing them with a snap-fit carrier mechanism. The carrier unit uses elastic latching features that engage with the bracket without requiring any fastening tools, thus removing the harmful element (screws) while maintaining connection stability through the elastic retention mechanism.
Solution Approach 2:
The patent replaces the traditional mechanical screw-fastening system with an elastic snap-fit mechanism. The carrier unit incorporates elastic latching features that automatically engage and disengage through simple insertion and removal motions, substituting the complex multi-step screw fastening process with a single-action mechanical engagement system.
2Reliability
If screws and fasteners are used to install HDDs, then the connection reliability is improved, but the device complexity increases
Solution Approach 1:
The patent removes screws, fasteners, and associated fastening tools from the installation system, significantly reducing the number of components and steps required. The carrier unit and bracket are designed to work together with simple geometric interlocking features, eliminating the need for separate fastening elements and reducing overall system complexity.
Solution Approach 2:
The carrier unit incorporates self-latching elastic features that automatically engage with the bracket upon insertion, without requiring external tools or assistance. The elastic latching mechanism self-adjusts and self-secures the HDD in place, making the installation process self-service and eliminating the need for complex fastening procedures.
3Reliability
If traditional fastening methods are used, then the HDD installation is secure, but the installation time increases
Solution Approach 1:
The carrier unit is pre-designed with integrated elastic latching features and positioning structures that are prepared in advance during manufacturing. The bracket is pre-configured with corresponding engagement features, so that when the HDD is inserted, the latching mechanism immediately engages without requiring any additional actions or adjustments, significantly reducing installation time while maintaining security.
Solution Approach 2:
The patent replaces the time-consuming screw fastening process with an instantaneous elastic snap-fit mechanism. The elastic latching features engage automatically upon insertion, providing secure fixation in a single motion rather than requiring multiple steps of screw insertion, tightening, and verification, thus dramatically reducing installation time.

AI summary
A carrier assembly for installing a hard disk drive (HDD) rapidly without tools or screws or other fasteners disk includes a bracket and a carrier. The carrier is movably disposed within the bracket. The hard disk drive is disposed with the carrier. The bracket includes a side plate and a plurality of first protrusions arranged on the side plate along with electrical connectors. The side plate defines interconnecting slots, a vertical first slot and a horizontal second slot. The carrier includes a lateral plate, a rotating handle connected to the lateral plate, and second protrusions arranged on the lateral plate. When the rotating handle is manually rotated, the second protrusion becomes locked within the first slot or the second slot to fix the HDD in place.
