Memory Module Retention Mechanism for Tall DIMM Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tall format memory modules experience mechanical and electrical failures due to their shifted center of gravity and weight, leading to flexing and stress on connectors during movement or vibrations, which can cause dislodgment and failure.
Innovation Solution
A retention mechanism with slots and retention elements is used to secure memory modules, providing stability and reducing movement, including a connector bar and retention pins that engage with the top edge of the modules to mitigate stress on connectors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If memory modules are made taller to increase capacity, then storage capacity is improved, but mechanical stability deteriorates due to shifted center of gravity and increased weight
Solution Approach 1:
The patent introduces a retention mechanism that extends in a third dimension (vertically above the connector) to provide additional support for tall memory modules. The retention element creates a new spatial dimension for stabilization, allowing the modules to maintain their increased height while gaining mechanical stability through overhead support structures.
2Quantity of substance
If memory modules are made taller to increase capacity, then storage capacity is improved, but connector reliability deteriorates due to increased stress and flexing
Solution Approach 1:
The retention mechanism serves as an intermediary support structure between the tall memory module and the chassis. This intermediate element provides additional attachment points and distributes the weight and stress away from the connector, preventing direct transmission of mechanical loads that would cause flexing and potential failure.
3Stability of the object's composition
If memory modules are secured with a retention mechanism, then mechanical stability is improved, but device complexity increases
Solution Approach 1:
The retention mechanism is designed to be universally applicable across different memory module configurations and chassis types. By creating a standardized multi-functional component that can serve various stabilization needs, the patent reduces overall system complexity despite adding the retention feature, as the same basic structure adapts to different scenarios.
