Solution Overview

Problem

The current methods of installing memory modules into computing devices often result in elevated strain rates, leading to potential damage to the memory module, memory socket, and circuit board due to improper force application, which can cause system failures and inefficiencies in high-speed memory installation.

Innovation Solution

A memory insertion machine with moveable insertion rods and a controller that applies a gradually decreasing deceleration force to ensure proper seating of memory modules into memory sockets, utilizing empirical strain rate testing data to optimize the insertion process and minimize damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current installation motion is used, then installation speed is maintained, but strain rate increases causing damage to memory module, socket, and circuit board

Engineering Contradiction:

Improvedamage preventionVSAvoidinsertion speed

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The patent implements a dynamic motion profile that continuously adjusts insertion speed during the process. The system transitions from higher speed at the beginning of insertion to gradually decreasing speed as the memory module approaches full insertion, optimizing both installation efficiency and damage prevention through real-time velocity modulation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the kinetic parameters of insertion by implementing a controlled deceleration profile. The system modifies velocity and acceleration parameters during the insertion process, specifically reducing speed as the memory module nears its final position, thereby controlling strain rate while maintaining overall installation productivity

Inventive Principle:

Principle #35Parameter changes

2Productivity

If high insertion force is applied, then insertion speed is maintained, but damage risk to memory components increases

Engineering Contradiction:

Improveinstallation efficiencyVSAvoidstrain rate damage

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements periodic action through a multi-phase insertion sequence. The process includes an initial high-speed phase for rapid approach, followed by a deceleration phase, and finally a low-speed seating phase. This periodic variation in insertion rate optimizes productivity while preventing damage through appropriate force application at each stage

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The patent applies beforehand cushioning by pre-programming the deceleration profile before insertion begins. The control system prepares the gradual speed reduction sequence in advance, ensuring that damaging forces are prevented before they can occur during the critical final seating phase of memory module installation

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

The technology relates to a memory insertion machine for inserting memory modules into memory sockets on a circuit board. The memory insertion machine may include one or more insertion rods moveably mounted to one or more vertical guides and an insertion controller. The insertion controller may be configured to apply an insertion force to a memory module in a memory socket by controlling the movement of the one or more insertion rods on the one or more vertical guides. The movement of the one or more insertion rods may have a gradually decreasing deceleration as the insertion rods move towards the memory socket.
