Solution Overview
Problem
Existing methods for mounting computing components to printed circuit boards in data centers are often cumbersome, prone to component damage, and difficult to automate, especially in large data centers where frequent swapping is required.
Innovation Solution
The use of an L-shaped latch tensioned by a spring, which secures computing components to printed circuit boards through a pivot point and anchor, allowing for easy rotation between locked and unlocked positions, facilitating quick installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting tools like screws or pins are used to secure computing components, then the components can be firmly mounted to the printed circuit board, but the components or tools may break from regular usage and the mounting process becomes complex and difficult to automate
Solution Approach 1:
The latch mechanism is divided into distinct functional segments: the L-shaped latch body, the pivot point for rotation, the spring for tension, and the hook for engagement. This segmentation allows each component to perform its specific function independently while contributing to the overall simple and reliable mounting system.
Solution Approach 2:
The spring-loaded latch mechanism is designed to automatically engage and lock the computing component in place without requiring additional tools or complex assembly steps. The spring provides continuous tension to maintain the locked position, and the latch can be easily released by applying force to the distal end, enabling self-servicing and frequent swapping.
2Adaptability or versatility
If computing components are frequently swapped in large data centers, then system flexibility and adaptability improve, but the time and energy required for installation increase
Solution Approach 1:
The latch mechanism incorporates dynamic elements including the L-shaped latch that rotates around the pivot point, and the spring that continuously adjusts tension. This dynamic design allows for rapid engagement and disengagement of computing components, facilitating frequent swapping without time loss.
Solution Approach 2:
The latch mechanism can be easily removed from the printed circuit board by rotating the L-shaped latch around the pivot point, extracting the computing component from its mounted position. This extraction process is simplified and requires minimal effort, enabling quick component replacement.
3Manufacturing precision
If complex component mounting systems are used to secure computing components precisely, then mounting precision improves, but automation becomes difficult and the process becomes too difficult for machines and robots
Solution Approach 1:
The complex mechanical mounting systems are replaced with a simplified spring-loaded latch mechanism that provides sufficient precision through elastic tension rather than complex mechanical constraints. This substitution makes the system compatible with automated machines and robots while maintaining adequate mounting precision.
Solution Approach 2:
The mounting system uses spring tension as a controllable parameter to achieve precise component positioning and securing. By adjusting the spring properties and latch geometry, the desired mounting precision is achieved through a simple parameter change rather than complex mechanical adjustments, enabling automation.
