Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently transmitting data packets at different transmission rates, particularly in power line communication, where high-speed and low-speed data transmission methods are not effectively integrated, leading to inefficiencies and potential data loss.
Innovation Solution
A communication apparatus and system that includes converters to convert low-speed packets into high-speed packets and vice versa, using generation and restoration units to ensure seamless data transmission across different transmission rates, with hardware circuits implementing these functions without software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is transmitted at high speed using high-speed packets, then transmission efficiency is improved, but compatibility with low-speed communication systems deteriorates
Solution Approach 1:
The patent introduces a conversion device as an intermediary component that translates between high-speed packets and low-speed packets. This mediator enables high-speed transmission when possible while maintaining compatibility with low-speed systems through automatic conversion, resolving the contradiction between transmission efficiency and system compatibility.
Solution Approach 2:
The system dynamically changes transmission parameters (packet format, transmission rate) based on the communication partner's capabilities. By adjusting packet structures and transmission speeds according to whether the partner supports high-speed communication, the system achieves both high efficiency when applicable and broad compatibility when needed.
2Adaptability or versatility
If conversion between different transmission rates is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the conversion function into a separate, dedicated conversion device rather than embedding complex conversion logic throughout the entire system. This modular approach reduces overall system complexity by isolating the adaptive functionality to a specific component that can be managed independently.
3Speed
If low-speed packets are converted to high-speed packets in real-time, then transmission speed is improved, but processing time increases
Solution Approach 1:
The conversion device performs packet conversion operations in advance before actual data transmission begins. By pre-converting low-speed packets to high-speed packets when the communication partner supports high-speed transmission, the system eliminates conversion delays during critical data transfer phases, achieving both high speed and minimal processing time loss.

AI summary
A first communication apparatus is configured to transmit a first packet at a first transmission rate, and includes a first interface, a generation unit, and a second interface. The first interface is configured to receive a second packet transmitted at a second transmission rate lower than the first transmission rate. The generation unit is configured to, each time the first interface receives a second bit group having number of bits smaller than the number of bits of a data main body that can be included in the first packet out of a first bit group to be transmitted included in the second packet, sequentially generate the first packet including the data main body including the second bit group. The second interface is configured to, each time the generation unit generates the first packet, sequentially transmit the first packet.
