Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hard disks are fastened with screws in the assembly, then the hard disks can be securely fixed, but the assembly becomes difficult to disassemble without additional tools in limited cabinet spaces
Solution Approach 1:
The bracket is designed with an elastic deformation mechanism that enables self-fastening and self-release functionality. The elastic component deforms under compression to lock the hard disk in place, and can be manually actuated to release without requiring external tools, making the system self-sufficient for both securing and releasing operations.
Solution Approach 2:
The traditional screw-based mechanical fastening system is replaced with an elastic deformation-based locking mechanism. The elastic component utilizes material elasticity to provide both the locking force and the release mechanism, eliminating the need for threaded fasteners and screwdrivers, thereby simplifying the mechanical system for tool-free operation.
2Reliability
If traditional screw-based fastening is used, then hard disks can be securely assembled, but assembly efficiency is reduced due to the need for screwdrivers and additional tools
Solution Approach 1:
The elastic fastening mechanism performs both the fastening and release functions without requiring external tools. The elastic component automatically locks when compressed during assembly, and can be manually actuated to release, making the entire process self-sufficient and eliminating the need for screwdrivers or other assembly tools, thereby significantly improving assembly efficiency.
Solution Approach 2:
The invention extracts and eliminates the screw and screwdriver components from the assembly system. By removing these unnecessary elements and replacing them with a single elastic component that provides both fastening and release functionality, the system reduces the number of parts and simplifies the assembly process, directly improving productivity.
3Reliability
If screws are used to fasten hard disks, then the hard disks can be firmly fixed, but the complexity of handling and managing assembly tools increases in compact spaces
Solution Approach 1:
The elastic fastening system is designed to be self-operating without requiring external tools. The elastic component provides the necessary fixation force through its material properties, and can be manually actuated to release, eliminating the need for screwdrivers or other specialized tools. This self-service capability significantly reduces the complexity of handling and managing assembly tools in compact server spaces.
Solution Approach 2:
The invention removes the screw and associated tool requirements from the fastening system. By extracting these complex elements and replacing them with a simple elastic component that provides both fixation and release functionality, the system dramatically reduces the complexity of tool handling and management, making it more suitable for compact environments.

AI summary
A hard disk assembly includes a tray, a bracket, and a carrier. The tray includes plural protrusions. The bracket is disposed on the tray for fastening a hard disk device. The bracket includes a bracket body having plural slots thereon, and plural pins disposed on opposite sides of the bracket body. The slots are respectively engaged with the protrusions. The pins are disposed between the bracket and the tray. The carrier is pivotally connected to the tray. The carrier includes two ribs. Each rib has a curved surface for touching and pulling the pins. Therefore the bracket can be slidably moved on the tray along the slots.
