Solution Overview

Problem

The force applied when plugging and unplugging connectors from processor modules in server racks can damage the processor module and/or the processor socket, leading to potential damage during installation and removal processes.

Innovation Solution

A processor retainer apparatus is introduced, comprising a load frame connected to the motherboard adjacent to the processor socket and a rotatable processor retainer that can be positioned in closed, opened, and installation positions, providing a secure retention mechanism for the processor module by exerting a controlled force to prevent bending or damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If connectors are plugged and unplugged from processor module communication connections, then communication connectivity is improved, but detrimental force is applied to the processor module causing potential damage

Engineering Contradiction:
Improvecommunication connectivityVSAvoidforce damage to processor module
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The processor retainer acts as an intermediary component between the processor module and the external environment. It absorbs and distributes the forces applied during connector plugging and unplugging operations, preventing these forces from being directly transmitted to the processor module and socket. The retainer's flexible material and structural design allow it to deform elastically under applied forces, thereby protecting the delicate processor module while still permitting necessary maintenance operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If a retention mechanism is added to protect the processor module, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improveprocessor module protectionVSAvoidretention apparatus structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The processor retainer is constructed from a flexible material that forms a thin protective shell around the processor module. This flexible structure provides protection without requiring complex mechanical assemblies, multiple fasteners, or rigid components. The retainer can deform elastically to accommodate the processor module and absorb external forces, while maintaining a simple single-piece or minimal-component design that integrates easily with the existing processor socket architecture.

Inventive Principle:
Principle #30Flexible shells and thin films

3Stability of the object's composition

If the processor retainer is securely locked to protect the module, then stability is improved, but ease of operation for installation and removal decreases

Engineering Contradiction:
Improveprocessor module stabilityVSAvoidinstallation and removal convenience
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The processor retainer employs a dynamic locking mechanism that transitions between locked and unlocked states. The retainer can be easily released by applying a simple release force (such as pressing a release tab or moving a release lever), which causes the retainer to deform elastically and disengage from its locked position. Once released, the retainer can be quickly removed from the processor module. This dynamic design allows the retainer to provide strong retention during normal operation while enabling rapid installation and removal by end users without requiring tools or complex procedures.

Inventive Principle:
Principle #15Dynamics

AI summary

An apparatus includes a motherboard with a processor socket, a load frame connected to the motherboard adjacent to at least two sides of the processor socket, and a processor retainer rotatably connected to the load frame, the processor retainer being positionable in a closed position, an opened position, and an installation position. The processor retainer extends over the processor socket when the processor retainer is in the closed position.
