CAMM Pre-Assembly Using Friction Snap Fastener Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing CAMM topologies require multiple loose parts and are cumbersome to install due to limited access in information handling systems, with screws easily getting lost or causing damage, and assembly is challenging in tight environments.
Innovation Solution
A pre-assembly method using a friction snap mechanism with a profiled mounting through-hole and a friction snap on a screw to securely hold the CAMM, compression connector, and mounting plate together, allowing for easy disassembly and reassembly with different compression connector profiles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw assembly methods are used for CAMM, then secure mounting is achieved, but assembly becomes cumbersome and parts are easily lost or damaged due to limited access
Solution Approach 1:
The patent combines the CAMM, compression connector, and fastener into a pre-assembled unit where the fastener is integrated through the mounting through-hole of the CAMM. This merging eliminates the need to handle separate loose screws during installation, preventing parts loss while maintaining secure mounting through the integrated fastener mechanism.
Solution Approach 2:
The CAMM and compression connector are pre-assembled with the fastener integrated through the mounting through-hole before final installation. This preliminary assembly action ensures proper alignment and positioning is achieved in advance, simplifying the final installation step while ensuring reliable mounting.
2Reliability
If multiple loose parts are used for CAMM assembly, then secure connections are achieved, but inventory management becomes difficult and parts loss risk increases
Solution Approach 1:
The patent merges multiple components (CAMM, compression connector, and fastener) into a single pre-assembled unit. This reduces the number of separate parts from three to one integrated assembly, simplifying inventory management while maintaining secure connections through the integrated fastener mechanism.
3Reliability
If traditional assembly methods are used in tight environments, then secure mounting is achieved, but assembly time increases due to limited access
Solution Approach 1:
The CAMM and compression connector are pre-assembled with proper alignment features and integrated fasteners before final installation. This preliminary action ensures that during the actual installation in tight environments, the components are already positioned correctly, eliminating the need for complex alignment maneuvers and significantly reducing assembly time while maintaining mounting security.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates easier inventory management and assembly by allowing pre-assembly of CAMM components as a single unit, reducing the risk of parts loss and damage, and ensuring secure electrical connections.
Implementation Method 1
The fastener may include a friction snap with a first diameter. The compression connector may include a profiled mounting through-hole. When the fastener is inserted through the mounting through-hole and the profiled mounting through-hole, and when the friction snap comes into contact with the narrowest portion, the friction snap may be pushed through the narrowest portion

AI summary
An apparatus is provided for mounting a compression attached memory module (CAMM) to a printed circuit board (PCB). The apparatus includes the CAMM, a fastener and a z-axis compression connector. The CAMM includes a mounting through-hole. The fastener includes a friction snap with a first diameter. The compression connector includes a profiled mounting through-hole. The profiled mounting through-hole has a narrowest portion having a second diameter that is less than the first diameter. When the fastener is inserted through the mounting through-hole and the profiled mounting through-hole, and when the friction snap comes into contact with the narrowest portion, the friction snap is pushed through the narrowest portion, and, after pushing the friction snap through the narrowest portion, the CAMM, the compression connector, and the fastener are aligned and retained as a unit.
