Hard Disk Mounting Assembly with Push Rod Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hard disk maintenance methods for servers are cumbersome and time-consuming due to the complex disassembly and assembly requirements of hard disk backplanes, which are often damaged and require regular maintenance, especially when hard disks need to be plugged and unplugged perpendicular to the ground.
Innovation Solution
A structure comprising a housing, hard disk bracket, hard disk backplane, and hard disk mounting assembly with stoppers, push rods, and elastic sheets that allow for tool-free quick mounting and removal of hard disks, enabling the hard disk backplane to be plugged and unplugged from the rear end of the housing, simplifying maintenance by reducing the number of connection parts and providing a locking function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the hard disk backplane is fixed to the bottom end of the housing to strengthen the machine body, then the structural strength is improved, but the ease of maintenance deteriorates because the hard disk backplane cannot be simply plugged and unplugged
Solution Approach 1:
The hard disk bracket is divided into a first hard disk bracket and a second hard disk bracket that can be separated from each other. The first hard disk bracket is clamped with the second hard disk bracket through stoppers and fixture blocks, allowing the hard disk backplane to be accessed and removed without disassembling the entire housing structure, thus maintaining structural strength while enabling easy maintenance.
Solution Approach 2:
The hard disk backplane is extracted from the traditional fixed bottom mounting position and moved to a removable position accessible through the front end of the housing. The push rod mechanism with stoppers allows the hard disk bracket to be pushed outward, enabling the hard disk backplane to be taken out for maintenance without affecting the overall structural integrity of the housing.
2Stability of the object's composition
If the hard disk backplane is provided with many plug-in parts to strengthen the machine body, then the structural stability is improved, but the device complexity increases making disassembly and assembly complicated
Solution Approach 1:
The connection mechanism is segmented into modular components: stoppers with protrusion parts, fixture blocks with openings, and a push rod with protruded blocks. These segmented parts work together through simple geometric interlocking rather than multiple complex plug-in parts, reducing device complexity while maintaining structural stability.
Solution Approach 2:
Instead of using multiple plug-in parts that require precise alignment and assembly, the invention uses a push rod mechanism that pushes the stoppers outward to release the locking condition. This inverts the traditional approach where parts are inserted to lock; here, parts are pushed to unlock, simplifying the maintenance operation.
3Strength
If the hard disk bracket is fixed at the front end and rear end of the housing to strengthen the structure, then the structural strength is improved, but the maintenance time increases as all hard disks must be unplugged one by one
Solution Approach 1:
The hard disk bracket is segmented into two separable parts (first and second hard disk brackets) that are clamped together. This segmentation allows the entire hard disk bracket assembly to be quickly removed from the housing by pushing the second bracket outward, enabling maintenance of multiple hard disks simultaneously rather than unplugging each one individually, thus reducing maintenance time while maintaining structural strength.
4Reliability
If the hard disk bracket uses a complex clamping mechanism with multiple parts to secure hard disks, then the reliability of hard disk fixation is improved, but the ease of operation deteriorates requiring tools and complex procedures
Solution Approach 1:
The clamping mechanism is designed so that the normal state is clamped (reliable fixation) and the release state is achieved by pushing the push rod outward. The stoppers are normally held inward by the clamping force, and pushing the push rod outward releases the stoppers from the fixture blocks, allowing easy tool-free operation while maintaining reliable fixation during normal operation.
Solution Approach 2:
The push rod mechanism with stoppers and fixture blocks creates a self-locking clamping system that maintains reliable fixation without requiring additional tools or complex procedures. The geometric interlocking of the stoppers with the fixture blocks provides automatic locking, and the same mechanism allows easy release by simply pushing the push rod, making the system self-servicing.
