Storage Device Sled Tapered Post Vibration Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Storage devices in enclosures face issues with induced shock and vibration, leading to performance degradation and reliability concerns due to the transfer of mechanical oscillations from spinning devices and external forces.
Innovation Solution
The design of an improved storage device sled with tapered posts and a latching clip mechanism reduces the number of parts, allowing for secure mounting and easy assembly/disassembly, while altering the structural stiffness around fastener holes to mitigate shock and vibration effects without additional materials or manufacturing steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mounting methods with multiple fasteners and separate components are used, then secure mounting is achieved, but assembly time and complexity increase
Solution Approach 1:
The patent combines multiple separate mounting components (fasteners, mounting members, alignment features) into a single integrated sled structure. The sled includes integrated mounting holes, alignment projections, and fastener receptacles that are formed as one piece, eliminating the need for separate parts and reducing assembly steps while maintaining secure mounting functionality.
2Reliability
If rigid mounting structures are used, then secure mounting is achieved, but shock and vibration are transferred to storage devices
Solution Approach 1:
The patent modifies the structural parameters of the sled by incorporating features that alter stiffness distribution. The sled design includes flexible mounting members and strategically placed reinforcement zones that change the mechanical properties of the structure, allowing it to absorb and dissipate vibration energy while maintaining overall structural integrity and secure mounting.
3Reliability
If precision manufacturing is used to reduce vibration, then performance is maintained, but manufacturing cost increases
Solution Approach 1:
The patent divides the sled into functional zones with different manufacturing requirements. Critical areas requiring high precision (such as fastener receptacles and alignment features) are manufactured with tight tolerances, while non-critical structural areas use standard manufacturing tolerances. This segmented approach maintains performance stability in key areas while reducing overall manufacturing cost.

AI summary
An improved storage device sled is provided. The storage device sled includes first and second portions, each of which includes a threaded fastener, a longitudinal member, and a bezel member. The longitudinal members are configured to couple to mounting holes of a storage device. Each of the bezel members is orthogonal to a longitudinal member. One of the bezel members includes a latching clip and cutouts to receive one or more alignment projections. The other bezel member includes a latching clip receiver, configured to receive and capture the latching clip, and the one or more alignment projections. Each of the longitudinal members includes a hole for the threaded fastener, which retains the longitudinal member to a mounting hole on a side of the storage device. The longitudinal members also include a tapered post, which captures a mounting hole on a side of the storage device.
