Multifunction Wireform Latch for 2.5-Inch Hard Drive Brackets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hard disk drive brackets designed for standard 3.5″ drives are not adaptable to the smaller form factor of 2.5″ hard disk drives, leading to constrained mechanical packaging requirements and a need for a compact, low-cost, and robust mechanism that can accommodate swappable 2.5″ drives.
Innovation Solution
A hard disk drive bracket featuring a bezel with a rotatable lever arm and a multifunction wireform that latches the lever arm in the closed position, releases it upon pressing a button, and biases the release button, utilizing a single wire with a closed end and two free ends to perform these functions efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional 3.5" drive bracket designs are used, then standard drive accommodation is achieved, but adaptability to smaller 2.5" drives is lost
Solution Approach 1:
The wireform structure serves multiple functions simultaneously: it acts as a latch to hold the lever arm in the closed position, provides a release mechanism when the button is pressed, and biases the lever arm toward the closed position. This multi-functionality allows the bracket to adapt to smaller 2.5" drives while managing mechanical complexity through integration of functions into a single component.
2Volume of moving object
If a compact mechanism is implemented for 2.5" drives, then space efficiency is improved, but mechanism robustness may be compromised
Solution Approach 1:
The wireform structure utilizes flexible wire elements that can bend and deform to provide the latching and release functions. The wireform's flexibility allows it to accommodate the compact 2.5" drive form factor while maintaining sufficient mechanical strength through the wire's material properties and geometric configuration, ensuring robustness despite the reduced size.
3Reliability
If multiple components are used for latching and release functions, then functional reliability is improved, but part count and cost increase
Solution Approach 1:
The wireform structure merges the latch, release mechanism, and biasing spring into a single integrated component. The wireform's continuous structure provides all three functions simultaneously, reducing the part count compared to traditional designs that would use separate latch arms, springs, and release buttons, while maintaining functional reliability through the coordinated geometry of the wireform elements.

AI summary
A hard disk drive bracket includes a bezel, a lever arm attached to the bezel rotatably between a closed position against the bezel and an open position apart from the bezel, wherein a hard disk drive is locked into the hard disk drive bracket when the lever arm is in the closed position, and a multifunction wireform, wherein the multifunction wireform latches the lever arm in the closed position and releases the lever arm into the open position. The hard disk drive bracket may include a release button, wherein the multifunction wireform releases the lever arm upon pressing of the release button. The multifunction wireform may hold and bias the release button. A method of operating a hard disk drive bracket includes disposing a multifunction wireform into a bezel; attaching a lever arm to the bezel rotatably between a closed position and an open position; latching a lever arm against the bezel in the closed position and releasing the latched lever arm into the open position based on operation of the multifunction wireform. The method may include holding and biasing a release button by the multifunction wireform.
