Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for installing and removing hard disk drives (HDDs) are cumbersome due to the need for multiple screws, making the process tedious and time-consuming.
Innovation Solution
A fixing apparatus comprising a first fixing plate, a bracket, and a transverse bar, with pivotally attached components and shock-absorbing pins, allows for easy engagement and disengagement of the HDD by pivoting mechanisms and wedged blocks, facilitating convenient installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple screws are used to fasten the HDD on the drive bracket, then the HDD is securely mounted, but the installation and removal operations become tedious and time-consuming
Solution Approach 1:
The fixing apparatus is divided into separate functional components: a fixing plate with multiple fixing members (pins) that can be independently engaged, a transverse bar for alignment, and a bracket assembly. This segmentation allows the HDD to be secured through multiple pins simultaneously while enabling easy release by simply removing the transverse bar, thus resolving the contradiction between secure mounting and ease of operation.
Solution Approach 2:
The fixing apparatus transitions from a static screw-based system to a dynamic pin-based system where the transverse bar can be easily inserted and removed. The pins are designed to be inserted through the HDD sidewalls and engaged with the fixing plate, allowing the HDD to be quickly secured and released without the need for multiple screws, thereby improving ease of operation while maintaining reliability.
2Manufacturing precision
If multiple screws are fastened at the same time for proper balanced installation, then the HDD is properly installed, but the installing and removing operations become tedious
Solution Approach 1:
The fixing plate is pre-configured with multiple fixing members (pins) positioned at predetermined locations and orientations. The transverse bar is designed with features that guide the pins into proper alignment before engagement. This preliminary arrangement ensures that when the HDD is installed, the pins automatically engage at the correct positions and orientations, achieving balanced installation without requiring complex multi-screw operations.
Solution Approach 2:
The transverse bar acts as an intermediary component that facilitates the engagement of multiple pins simultaneously. By inserting the transverse bar through the HDD sidewalls and engaging with the fixing plate, it ensures proper alignment and balanced distribution of the pins, thereby achieving precise installation while simplifying the operation to a single insertion action.
3Reliability
If a screw-based mounting system is used, then the HDD can be securely fixed, but the complexity of the mounting process increases
Solution Approach 1:
The complex screw-based mounting system is replaced by extracting the essential securing function and implementing it through simpler pin-and-plate mechanisms. The transverse bar is removed as a separate component, and its function is integrated into the fixing plate assembly. This extraction and simplification reduces the overall device complexity while maintaining the reliability of secure HDD fixing.
Solution Approach 2:
Multiple fixing members (pins) are merged into a single fixing plate assembly that can be installed as one unit. The transverse bar is combined with the fixing plate through integral engagement features, creating a unified assembly that simplifies the mounting process. This merging reduces the number of separate components and operations required, thereby reducing device complexity while maintaining secure fixing capability.

AI summary
An exemplary fixing apparatus is for mounting a hard disk drive having a plurality of holes in sidewalls thereof. The fixing apparatus includes a first fixing plate, a bracket, and a transverse bar. The bracket includes a second fixing plate, and a bezel assembly attached to a first end of the second fixing plate. Each of the first fixing plate and the second fixing plate include a plurality of fixing members formed at inside walls thereof to engage in the holes of the disk drive. The first fixing plate is pivotally attached to a free end of the bezel assembly. One end of the transverse bar is pivotally attached to a second end of the second fixing plate opposite to the first end and the other end of the transverse bar detachably engages with the first fixing plate.
