Solution Overview

Problem

Modern computing systems face challenges in securely mounting computer processors within sockets due to the need for applied forces 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 that apply forces to secure the processor within the socket, utilizing an activate lever and a hinge lever to ensure reliable and secure mounting through torsion springs and interlocking mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a force is applied to the processor to maintain reliable electrical connection, then the reliability of electrical connection is improved, but the complexity of the mounting mechanism increases

Engineering Contradiction:
Improveelectrical connection reliabilityVSAvoidmounting mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the load plate and retention levers into an integrated mounting mechanism where the load plate serves as both the force application surface and the structural element that transmits force to the processor. The retention levers are directly coupled to the load plate, merging multiple functions into a unified structure that reduces overall complexity while maintaining reliable electrical connection through controlled force application.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The load plate serves multiple functions: it applies downward force to secure the processor, provides a mounting surface for the retention levers, and acts as a structural transfer element between the levers and the processor. This multi-functionality reduces the need for separate components, thereby reducing complexity while ensuring reliable electrical connection through consistent force application.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If multiple levers are used to apply force to the processor, then the reliability of mounting is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improvemounting reliabilityVSAvoidprocessor installation ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The mounting mechanism is segmented into distinct functional elements: the load plate for force application and multiple retention levers positioned at different locations. This segmentation allows each lever to independently contribute to securing the processor, improving mounting reliability through distributed force application, while maintaining ease of operation by allowing sequential or simultaneous engagement of individual levers.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The retention levers are designed to be movable rather than fixed, allowing them to be dynamically positioned during processor installation and then secured in place. This dynamic capability enables easy operation during installation while maintaining reliable mounting once the levers are engaged, as they can be easily moved for access and then locked into position to provide secure retention.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the load plate is securely fixed to the base, then the stability of processor mounting is improved, but the ease of processor removal deteriorates

Engineering Contradiction:
Improveprocessor mounting stabilityVSAvoidprocessor removal ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The load plate is designed with dynamic coupling to the base through the retention levers rather than rigid fixed mounting. The levers can be easily moved to disengage from the load plate, allowing the load plate to be quickly released and the processor removed. When the levers are engaged, they provide stable retention, thus achieving both stability during operation and ease of removal when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The retention levers are designed to automatically secure the load plate when engaged with the processor, eliminating the need for separate fastening operations. The levers self-lock into position, providing stable mounting without requiring additional securing steps that would complicate removal. For removal, the levers are simply disengaged, allowing the load plate and processor to be easily removed as a unit.

Inventive Principle:
Principle #25Self-service
