Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If chiplets with different detailed configurations use a standard communication protocol, then the system can achieve basic interoperability, but communication cannot be performed normally due to configuration differences

Engineering Contradiction:

Improveinteroperability between chipletsVSAvoidcommunication normality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies parameter changes by dynamically adjusting communication parameters based on the partner chiplet's configuration. The conversion device receives configuration information from the partner chiplet and modifies transmission parameters such as data width, clock frequency, and protocol version to match the partner's capabilities, enabling reliable communication despite hardware differences

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces a conversion device as an intermediary layer between chiplets with different configurations. This conversion device translates and adapts communication signals, protocols, and data formats between the local chiplet and the partner chiplet, mediating the interaction to ensure compatible and reliable communication across heterogeneous configurations

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If chiplet configurations are standardized to ensure communication, then communication reliability improves, but design flexibility and independence are reduced

Engineering Contradiction:

Improvecommunication reliabilityVSAvoiddesign independence

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the communication system into independent functional modules: a fixed standardized interface layer for reliable communication and a flexible configuration layer for independent design. This segmentation allows each chiplet to be designed independently with custom configurations while maintaining reliable communication through the standardized interface layer

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces dynamic configuration capabilities where chiplets can adapt their communication behavior in real-time based on partner detection. The system dynamically selects appropriate communication modes, data widths, and protocol versions during runtime, allowing independent design choices to be reconciled with reliable communication through adaptive behavior

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If conversion information is exchanged between chiplets, then interoperability between different protocols is enabled, but communication overhead and complexity increase

Engineering Contradiction:

Improveprotocol compatibilityVSAvoidconversion information processing

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by performing configuration information exchange and conversion setup during the initial connection phase before actual data communication begins. The conversion device pre-configures translation rules and parameters based on partner chiplet information, so that subsequent data communication can proceed without real-time conversion overhead

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent merges the conversion device functionality with existing chiplet components such as the interface controller or protocol layer, rather than adding completely separate conversion hardware. This integration reduces overall system complexity by combining multiple functions into unified components while still enabling protocol conversion capabilities

Inventive Principle:

Principle #5Merging (Combining)
