Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If chiplets are used to provide hardware flexibility and configurability, then adaptability and versatility are improved, but device complexity increases due to the need for orchestration and management systems

Engineering Contradiction:
Improvehardware configurabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a control plane as an intermediary layer between the physical chiplet infrastructure and the microservice workloads. This control plane includes a resource orchestrator that manages chiplet provisioning, a network manager that handles communication, and a resource scheduler that allocates resources. This mediator abstracts the complexity of chiplet management, allowing flexible hardware configuration without directly exposing system complexity to users.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the chiplet system into distinct functional components: compute chiplets, memory chiplets, I/O chiplets, and a control plane. This segmentation allows each component to be independently managed and configured, improving adaptability while organizing complexity into manageable segments rather than a monolithic system.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If dynamic configuration and orchestration are implemented, then adaptability and ease of operation are improved, but manufacturing precision and initial system setup complexity increase

Engineering Contradiction:
Improveconfiguration managementVSAvoidsystem integration precision
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The patent implements dynamic configuration capabilities where the control plane can provision, deprovision, and reconfigure chiplet resources at runtime based on workload requirements. The resource orchestrator dynamically allocates chiplets to microservices, and the resource scheduler adjusts resource allocation in real-time. This dynamic approach simplifies operation by allowing flexible reconfiguration without requiring precise pre-manufacturing planning for each specific use case.

Inventive Principle:
Principle #15Dynamics

3Productivity

If resource orchestration and management systems are added, then productivity and efficiency are improved through optimized resource utilization, but device complexity and power consumption increase

Engineering Contradiction:
Improveresource utilization efficiencyVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by stationary object

Solution Approach 1:

The control plane implements self-service mechanisms where the resource orchestrator automatically provisions and configures chiplet resources based on workload demands without requiring manual intervention. The resource scheduler autonomously allocates and deallocates resources, and the network manager automatically manages communication protocols. This automation improves productivity by optimizing resource utilization while reducing the operational overhead that would otherwise require additional power-consuming management infrastructure.

Inventive Principle:
Principle #25Self-service
