Solution Overview

Problem

Modern computing systems face challenges in securely mounting computer processors within sockets due to the need for consistent force application to maintain reliable electrical connections, which existing mechanisms fail to address effectively.

Innovation Solution

A dual force single point actuation integrated load mechanism is introduced, comprising a base, a load plate, and levers (activate and hinge) that apply forces to secure the processor within the socket, ensuring reliable electrical connections through torsion springs and lever interlocking mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single force mechanism is used to secure the processor, then the device complexity is reduced, but the reliability of the electrical connection deteriorates

Engineering Contradiction:
Improvemechanism complexityVSAvoidelectrical connection reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The securing mechanism is divided into two independent force application systems: a first force mechanism and a second force mechanism. Each mechanism independently applies force to the processor through separate load plates, ensuring that the electrical connection reliability is maintained through dual force application while keeping each individual mechanism relatively simple in structure.

Inventive Principle:
Principle #1Segmentation

2Reliability

If multiple forces are applied to secure the processor, then the electrical connection reliability is improved, but the device complexity increases

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The first and second force mechanisms are integrated into a single unified structure where both mechanisms share common components including the base, the processor socket, and the processor itself. The load plates are positioned to apply forces at different locations on the processor, and the mechanisms are coordinated to work together as a cohesive system, reducing overall complexity compared to completely separate mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If a complex mounting mechanism is used to ensure secure processor attachment, then the reliability is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improveprocessor attachment reliabilityVSAvoidprocessor removal ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The force mechanisms incorporate movable components including rotatable levers and adjustable load plates that can dynamically change their position and force application characteristics. The first and second load plates can be independently positioned and adjusted, allowing the system to adapt between a secured state for reliable operation and an released state for easy processor removal, providing operational flexibility.

Inventive Principle:
Principle #15Dynamics
