Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If VDSL bonding techniques are used to achieve high data transmission rate exceeding 100Mbps, then data transmission rate is improved, but the number of pairs must be increased
Solution Approach 1:
The patent implements dynamic resource allocation and scheduling in the G.hn network access device, allowing the system to adaptively manage available frequency bands and time slots. The domain master dynamically schedules transmissions for multiple domain slaves, optimizing data transmission rates without requiring additional physical pairs by efficiently utilizing existing medium resources through dynamic time-division and frequency-division multiplexing.
2Speed
If optical fiber is deployed to provide gigabit level data transmission service, then data transmission rate is improved, but replacement cost increases
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.
3Speed
If G.hn technology is used to provide wire-based gigabit home networks, then data transmission rate is improved, but network management complexity increases
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.
4Productivity
If dynamic resource allocation is implemented in G.hn network, then data transmission efficiency is improved, but device complexity increases
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.
