Floating Cam Pin Mechanism for Processor Expansion Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in consistently applying the retaining force between a processor expansion module (PEM) and the base system due to variations in stack-up tolerances, leading to potential misalignment and stress on connections.
Innovation Solution
The implementation of a floating cam pin mechanism, which includes a mounting bracket movably affixed to the side wall and tensioning springs connected between the mounting stud and the mounting hole, allows for a consistent application of retaining force by absorbing overpressure and ensuring sufficient connection pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid mounting structures are used to ensure stable connection, then mechanical strength is improved, but adaptability to stack-up tolerance variations deteriorates
Solution Approach 1:
The mounting bracket is designed to be movably affixed to the side wall rather than rigidly fixed, allowing it to dynamically adjust its position to accommodate stack-up tolerance variations. This mobility enables the bracket to self-align with the processor expansion module while maintaining secure retention, thus providing both strength and adaptability.
2Reliability
If fixed retention force is applied to ensure consistent connection pressure, then connection reliability is improved, but mechanical stress from tolerance variations worsens
Solution Approach 1:
The spring mechanism changes the retention force parameter dynamically based on the engagement conditions. As the mounting bracket moves to accommodate tolerance variations, the spring adjusts the retention force accordingly, ensuring consistent connection pressure without transmitting excessive mechanical stress to the electrical connections.
3Adaptability or versatility
If movable mounting bracket is used to accommodate tolerance variations, then adaptability is improved, but device complexity worsens
Solution Approach 1:
The mounting mechanism is segmented into distinct functional components: the movably affixed bracket, the spring element, and the retention features. This segmentation allows each component to perform its specific function independently, simplifying the overall design while achieving the required adaptability through the coordinated action of these simple, well-defined parts.

AI summary
An information handling system includes a processing system, a side wall, and a spring. The side wall includes a mounting stud and a capture mechanism to retain a second processing system. The capture mechanism includes a mounting bracket movably affixed to the side wall. The mounting bracket includes a mounting hole and a retention stud rigidly affixed to the mounting bracket. The retention stud engages with a retaining mechanism of the second processing system to couple the second processing system to the first processing system. The spring is attached between the mounting stud and the mounting hole.
