Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hard disks are directly fixed in an enclosure by screws, then the hard disk is securely mounted, but the assembly and disassembly process becomes inconvenient and complex
Solution Approach 1:
The mounting structure is divided into separate functional components: a bracket with positioning features and elastic elements, and a hard disk with corresponding positioning holes and recesses. This segmentation allows the bracket to be a reusable mounting component while the hard disk remains a replaceable storage device, simplifying both assembly and disassembly operations.
Solution Approach 2:
Elastic elements are introduced into the mounting structure to provide dynamic adjustment capability. These elastic elements allow the bracket to automatically adjust to slight variations in hard disk dimensions and positioning, while still maintaining secure mounting. The dynamic nature of the elastic mounting mechanism enables easy insertion and removal without requiring precise manual adjustment.
2Reliability
If multiple separate components are used for mounting, then the hard disk can be securely fixed, but the number of parts increases and assembly becomes more complex
Solution Approach 1:
Multiple mounting functions are merged into a single integrated bracket structure. The bracket combines positioning features (positioning protrusions), support functions (support surfaces), and securing mechanisms (elastic elements with limiting portions) into one unified component. This merging reduces the number of separate parts while maintaining reliable hard disk fixation through the coordinated action of these integrated features.
Solution Approach 2:
The bracket is designed as a universal mounting component that can accommodate different hard disk configurations. The positioning protrusions can engage with various positioning hole patterns, and the elastic elements can adjust to different hard disk dimensions. This multi-functionality allows a single bracket design to reliably mount multiple hard disks with slight variations, reducing the need for multiple specialized mounting components.
3Ease of operation
If traditional screw fixation is used, then the mounting structure is simple, but the hard disk cannot be easily removed for replacement or maintenance
Solution Approach 1:
The traditional screw-based mechanical fastening system is replaced with an elastic element-based mounting mechanism. Instead of requiring threaded fasteners and precise thread engagement, the invention uses elastic deformation and friction-based holding forces. This substitution maintains manufacturing simplicity while enabling tool-free or minimal-tool assembly and disassembly, greatly facilitating hard disk replacement and maintenance operations.

AI summary
A hard disk bracket for fixing a hard disk defining a plurality of positioning holes in two opposite sidewalls thereof includes a chassis and two substantially parallel rows of fixing members projecting from the chassis, spaced from each other, and receiving the hard disk therebetween. Each row of the fixing portion includes at least resilient two limiting portions each including a positioning pin received in the corresponding positioning hole to fix the hard disk and at least one supporting portion including a supporting plate parallel to the chassis to support the hard disk. The at least two limiting portions align with the at least one supporting portion. A distance between the surface of the chassis and the positioning pin is greater than that between the surface of the chassis and the supporting plate.
