Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple protocol converting devices are installed to support different transmission protocols, then protocol compatibility is improved, but device complexity and cost increase
Solution Approach 1:
The patent implements a universal transceiver device capable of supporting multiple transmission protocols (Ethernet, USB, CAN, RS-485, MOST, etc.) through a single multi-protocol stack architecture. This eliminates the need for multiple separate protocol converting devices, reducing network complexity while maintaining broad protocol compatibility through unified multi-functional design
Solution Approach 2:
The patent merges multiple protocol handling capabilities into a single integrated transceiver device with a unified multi-protocol stack. By combining what would traditionally require separate converting devices into one consolidated unit, the system reduces device complexity and network architecture overhead while maintaining support for diverse protocols
2Reliability
If multiple transmission lines are used to support different protocols, then protocol transmission reliability is improved, but infrastructure cost increases
Solution Approach 1:
The patent enables a single transmission line to carry multiple protocols simultaneously through the multi-protocol stack architecture. The transceiver device can identify and process different protocol types (Ethernet, USB, CAN, RS-485, MOST) over the same physical medium, eliminating the need for separate cables for each protocol while maintaining reliable transmission through protocol-specific handling
Solution Approach 2:
The patent merges multiple protocol transmissions into a single transmission line by implementing a unified multi-protocol stack. This consolidation reduces the quantity of cables required from multiple separate lines to a single shared medium, while protocol transmission reliability is maintained through dedicated protocol identification and processing mechanisms
3Adaptability or versatility
If protocol converting devices are deployed to meet new network standards, then adaptability to new standards is improved, but cost increases
Solution Approach 1:
The patent implements a future-proof multi-protocol stack architecture that can accommodate new transmission standards without requiring additional converting devices. The universal transceiver design allows seamless integration of emerging protocols through software-based protocol stacks, reducing infrastructure construction costs while maintaining adaptability to new standards
4Adaptability or versatility
If gateway devices are used to connect different protocol networks, then protocol interoperability is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces traditional gateway architecture with a universal transceiver device that natively supports multiple protocols through the multi-protocol stack. This eliminates the need for separate gateway devices that perform protocol interpretation, reducing gateway architecture complexity while maintaining protocol interoperability through unified multi-functional design

AI summary
The present invention relates to a method and an apparatus of transmitting data via a multi-protocol single-medium network. The method includes initializing a network; transmitting messages in the network; setting up the size and the protocol of the messages and assigning the messages to a multi-protocol stack of the PHY layer based on a network time sharing multitasking principle; assigning each of the messages to a proper time slot; checking whether or not all messages are assigned to the proper time slots; if yes, transmitting the messages; and receiving the messages by a network device and transmitting the messages to another network device via a single-medium network.
