Solution Overview

Problem

Conventional computing devices face issues with airflow obstruction due to the perpendicular orientation of GPUs relative to the motherboard, which generates excessive heat and requires suboptimal power connector routing using ribbon cables, leading to degradation.

Innovation Solution

A computing device design with a motherboard and add-on card oriented parallel to each other, featuring expansion connectors and power connectors aligned parallel to the motherboard, allowing for improved airflow and simplified cable routing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the GPU is oriented perpendicular to the motherboard according to conventional standards, then the device follows standard orientation requirements, but airflow is blocked and heat dissipation is impaired

Engineering Contradiction:

Improvestandard complianceVSAvoidGPU heat dissipation

Core Design Contradiction:

ReliabilityVSTemperature

Solution Approach 1:

The patent inverts the conventional perpendicular orientation of the GPU relative to the motherboard, instead orienting the GPU parallel to the motherboard. This inversion allows airflow to pass unobstructed along the elongate axis of the chassis, significantly improving heat dissipation while maintaining standard compliance through alternative design arrangements.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of operation

If the GPU is oriented perpendicular to the motherboard, then standard connector orientation is maintained, but memory modules and other components block airflow reaching the GPU

Engineering Contradiction:

Improveconnector orientationVSAvoidairflow to GPU

Core Design Contradiction:

Ease of operationVSTemperature

Solution Approach 1:

By inverting the GPU orientation from perpendicular to parallel relative to the motherboard, the patent eliminates the airflow blocking issue caused by memory modules and other perpendicular components. The GPU now receives unobstructed airflow along the chassis elongate axis, while connector functionality is preserved through adapted connection arrangements.
