Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional data accessing devices in server chassis face issues with vibration-induced resonance and loose screw problems due to inadequate anti-vibration design, making them difficult to assemble, disassemble, and maintain, while also compromising the Rotational Vibration Index (RVI) performance and service life.
Innovation Solution
An elastic-plate fixing structure with a base case and fastening unit, featuring an elastic buckle piece, pressing elastic plate, vibration absorbing pad, and clamping plates, which allows for screwless assembly and disassembly, providing a traveling space for the positioning protrusion to engage or disengage from the data accessing device's fixing hole, and absorbs vibrations to enhance stability and RVI performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If screw locking is used to mount data accessing device on fixed frame or tray, then stability during use is improved, but assembly and disassembly become time-consuming and complex
Solution Approach 1:
The fixing structure is divided into multiple components: a tray with positioning protrusions, a data accessing device with corresponding positioning holes, and separate fastening mechanisms. This segmentation allows the tray and device to be quickly aligned and connected without complex screw assemblies, reducing assembly time while maintaining stability through the distributed positioning protrusions and holes.
Solution Approach 2:
Positioning protrusions and positioning holes serve as intermediary elements that facilitate quick alignment and connection between the tray and data accessing device. These intermediaries enable tool-less assembly by providing precise mechanical guidance and secure engagement without requiring screws or other complex fastening mechanisms.
2Strength
If conventional screw fixing is used, then firm attachment is achieved, but vibration causes screws to loosen and device damage occurs
Solution Approach 1:
The fixing structure incorporates elastic components and flexible mounting mechanisms that can dynamically adapt to vibration forces. The positioning protrusions and holes are designed with tolerance ranges that allow slight movements and deformations under vibrational stress, preventing screw loosening and device damage while maintaining secure attachment.
Solution Approach 2:
The design includes vibration damping elements and cushioning structures positioned between the data accessing device and the tray. These elements are pre-installed to absorb and dissipate vibration energy before it can cause screw loosening or device damage, thereby improving anti-vibration reliability while maintaining attachment strength.
3Productivity
If fixed convex hull structures are used for tool-less fixing, then assembly speed is improved, but fastening reliability and RVI performance deteriorate
Solution Approach 1:
Instead of using uniform fixed convex hull structures throughout, the design implements localized positioning protrusions and holes at specific critical points where fastening is most needed. This localized approach maintains assembly speed by requiring minimal alignment while improving fastening reliability by concentrating securing forces at key locations rather than distributing them uniformly across convex hulls.
4Stability of the object's composition
If rigid fixed frame is used, then structural stability is improved, but vibration-induced resonance and device damage occur
Solution Approach 1:
The fixing structure combines rigid components (tray, positioning protrusions) with flexible or damping materials (vibration damping elements, elastic components). This composite construction maintains structural stability for precise positioning while the flexible elements absorb vibration energy and prevent resonance-induced device damage.
Solution Approach 2:
Vibration damping elements and elastic components serve as intermediary layers between the rigid tray and the data accessing device. These intermediaries decouple the rigid structures, allowing the tray to maintain its shape and positioning accuracy while the damping elements absorb vibration forces, preventing them from being transmitted to the device and causing resonance or damage.
