Solution Approach 1:

The G.hn network access device is designed to work with existing home network infrastructure including power wires, telephone wires, and coaxial cables. The domain master can dynamically allocate frequency bands and manage multiple domain slaves connected through these existing mediums, providing gigabit-level data transmission without requiring optical fiber deployment. This multi-functional approach allows the system to achieve high speeds by utilizing already-installed wiring infrastructure.

Inventive Principle:

If G.hn technology is used to provide wire-based gigabit home networks, then data transmission rate is improved, but network management complexity increases

Engineering Contradiction:
Improvedata transmission rateVSAvoidnetwork management complexity
Core Design Contradiction:

Solution Approach 1:

The patent implements a feedback mechanism where the domain master continuously monitors the status of domain slaves and available frequency bands. Based on this real-time feedback, the domain master dynamically adjusts resource allocation, schedules transmissions, and manages network resources. This feedback-driven approach simplifies network management by automating decision-making processes and enabling adaptive optimization without manual intervention.

Inventive Principle:

Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The G.hn network access device is segmented into distinct functional modules: a domain master responsible for resource allocation and scheduling, and domain slaves responsible for data transmission. This segmentation allows the complex dynamic resource allocation function to be concentrated in the domain master, while domain slaves maintain simpler operations. The modular architecture manages device complexity by distributing functions appropriately across different components.

Inventive Principle:
Principle #1Segmentation
