Memory Module Retainer Mounting for High-Vibration Sockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory modules in computer systems, particularly in ruggedized environments, face dislodgment due to high vibration and mechanical forces, leading to operational issues and errors.
Innovation Solution
The implementation of a retainer system that secures memory modules in memory sockets with triple redundancy along the x, y, and z axes, using a retainer that attaches to the memory module and socket latches to provide stability and retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If memory modules are mounted in standard memory sockets, then ease of installation and replacement is improved, but reliability under high vibration conditions deteriorates due to dislodgment
Solution Approach 1:
The retention system is divided into separate functional components: a retainer body that interfaces with the memory module, socket latches that engage with the retainer, and a mounting structure. This segmentation allows each component to be optimized for its specific function while maintaining overall reliability under vibration conditions.
Solution Approach 2:
The system provides triple redundancy by constraining the memory module along three orthogonal axes (x, y, and z directions). This multi-dimensional constraint approach ensures that vibration forces from any direction are counteracted, significantly improving reliability without compromising installation ease.
2Reliability
If retainer system with triple redundancy is implemented, then reliability under high vibration is improved, but device complexity increases due to additional components
Solution Approach 1:
Multiple retention functions are merged into integrated components. The retainer body combines the mounting interface, constraint mechanisms, and engagement features into a single piece. Similarly, the socket latches integrate multiple retention functions into unified structures, reducing the number of separate parts while maintaining triple redundancy.
Solution Approach 2:
The retainer and socket latch components are designed to perform multiple functions simultaneously: mechanical retention, vibration resistance, and easy release. This multi-functionality reduces the need for separate specialized components, thereby reducing overall device complexity while maintaining high reliability.
3Strength
If retainer attaches directly to memory module, then retention strength is improved, but manufacturing precision requirements increase due to alignment constraints
Solution Approach 1:
The retainer and socket latch components incorporate localized features such as tapered engagement surfaces, compliant elements, and self-aligning geometries at critical interfaces. These local quality enhancements ensure proper alignment and strong retention without requiring high precision throughout the entire manufacturing process.
Solution Approach 2:
The design incorporates geometric parameters and material properties that facilitate self-alignment during assembly. Tapered angles, elastic deformation characteristics, and interference fit dimensions are carefully selected to enable automatic alignment, reducing the need for high manufacturing precision while maintaining strong retention strength.

AI summary
A memory module operation system for operating in high stress environments with strong vibration. The application and use of a retainer to reduce and dampen the effects of system vibration and the application of dynamic loads can retain a memory module in place in a memory socket. Further, the retainer can operate to reduce the effects of electromagnetic interference and can act as a heat transport system to reduce thermal stress on components.
