Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If direct chip-to-chip communication is attempted, then communication simplicity is maintained, but communication reliability deteriorates when obstacles block the direct path

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidcommunication path complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces relay chips as intermediary devices to establish indirect communication paths between source and destination chips. When direct microwave communication is blocked or unavailable, the relay chips receive signals from the source chip via wireline bus, process them, and forward them to the destination chip, thereby ensuring communication reliability without requiring direct line-of-sight between communicating chips.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The communication system is segmented into multiple independent components: source chips, relay chips, and destination chips, each capable of independent operation. The communication path is divided into multiple hops rather than requiring a single direct link, allowing the system to route around obstacles and maintain reliability even when some paths are blocked.

Inventive Principle:
Principle #1Segmentation

2Productivity

If beamforming parameters are adjusted to optimize communication, then communication performance is improved, but system complexity increases

Engineering Contradiction:
Improvedata transfer rateVSAvoidbeamforming control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system performs preliminary beamforming initialization and parameter optimization during the link setup phase before actual data transmission begins. The wireline bus is used to exchange control information and pre-establish optimal beamforming parameters, so that during high-rate data transfer, the beamforming configuration is already optimized and no real-time adjustments are needed, thus achieving high productivity without complex real-time control.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces complex mechanical or real-time electronic beamforming adjustment mechanisms with pre-computed beamforming parameters transmitted via wireline bus. Instead of continuously adjusting beamforming during data transfer, the system uses preliminary wireline communication to establish optimal parameters, substituting real-time control complexity with simpler pre-configured parameters.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If relay chips are introduced to overcome communication obstacles, then communication coverage is improved, but system complexity increases

Engineering Contradiction:
Improvecommunication coverageVSAvoidsystem architecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Relay chips are designed with multi-functionality, serving both as communication intermediaries for extended coverage and as regular data processing units when not acting as relays. The same chip architecture can function as a source, relay, or destination depending on the communication scenario, reducing overall system complexity by using standardized multi-purpose components rather than specialized devices for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The relay chips autonomously determine whether to act as relays or direct communication participants based on local conditions and received control information. The wireline bus enables self-configuration where relay chips automatically establish appropriate communication paths without requiring complex centralized control, allowing the system to adapt to various topologies while maintaining relatively simple architecture.

Inventive Principle:
Principle #25Self-service
