Solution Overview

Problem

Conventional networking and computing systems face challenges with increasing computational and thermal density issues due to the integration of multiple processing components on a single server, leading to heat dissipation problems and increased component failure rates, necessitating the replacement of entire server racks when one component fails.

Innovation Solution

The implementation of disaggregated server devices with isolated GPUs and separate switch modules, allowing for modular, scalable networking architectures that minimize density concerns and facilitate easy maintenance by isolating switching hardware from computational hardware, enabling single GPU server devices and separate insertable switch modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple processing components are integrated on a single server to increase computational density, then computational power is improved, but heat dissipation problems and component failure rates worsen

Engineering Contradiction:

Improvecomputational powerVSAvoidcomponent failure rate

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent segments the server system into multiple independent server devices, each containing a limited number of processing components (e.g., one or two GPUs per server). This segmentation distributes the computational workload across multiple units while isolating heat generation and failure risks to individual devices rather than concentrating them in a single high-density server.

Inventive Principle:

Principle #1Segmentation

2Productivity

If multiple processing components are integrated on a single server to increase computational density, then computational power is improved, but heat dissipation problems worsen

Engineering Contradiction:

Improvecomputational powerVSAvoidheat dissipation

Core Design Contradiction:

ProductivityVSTemperature

Solution Approach 1:

By dividing the computational system into multiple server devices with fewer components each, the patent reduces the thermal load on any single device. Each server generates less heat individually, making thermal management more effective while collectively providing the required computational power through parallel processing across multiple units.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent transitions from a vertical integration approach (stacking multiple components in one server) to a horizontal expansion approach (adding multiple servers in a network). This dimensional shift distributes thermal load across space rather than concentrating it, allowing for better heat dissipation while maintaining computational scalability.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If entire server racks are replaced when one component fails to ensure system reliability, then system reliability is maintained, but maintenance time and operational disruption increase

Engineering Contradiction:

Improvesystem reliabilityVSAvoidmaintenance time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent creates modular server devices that can be independently replaced. When a failure occurs in one server device, only that specific unit needs to be replaced rather than the entire rack, significantly reducing maintenance time and operational disruption while maintaining system reliability through redundancy.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent changes the scale of replacement from system-level (entire rack) to component-level (individual server device). This parameter change in the granularity of replaceable units enables faster maintenance operations while preserving overall system functionality through the modular architecture.

Inventive Principle:

Principle #35Parameter changes

4Device complexity

If switching hardware is integrated with computational hardware to reduce system complexity, then device complexity is reduced, but maintenance difficulty and operational impact increase

Engineering Contradiction:

Improvesystem complexityVSAvoidmaintenance difficulty

Core Design Contradiction:

Device complexityVSEase of repair

Solution Approach 1:

The patent segments switching hardware into separate insertable switch modules that are physically and functionally isolated from computational server devices. This segmentation simplifies each individual component (servers focus on computation, switches focus on networking) while making maintenance easier by allowing independent replacement of switch modules without affecting computational hardware.

Inventive Principle:

Principle #1Segmentation
