Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate communication links are used for high-speed data and power supply configuration data, then data transmission reliability is improved, but device complexity and connection bulk increase
Solution Approach 1:
The patent combines high-speed data and power supply configuration data into a single serial communication link. The data communication circuit multiplexes these different data types over one physical connection, eliminating the need for separate connectors and reducing overall system complexity while maintaining reliable transmission of both data types.
Solution Approach 2:
The single communication link is designed to handle multiple functions simultaneously - transmitting both high-speed data and power supply configuration data. This multi-functional approach allows one connection to replace what would traditionally require multiple specialized links, reducing device complexity without sacrificing reliability.
2Reliability
If separate communication links are used for high-speed data and power supply configuration data, then data transmission reliability is improved, but device size increases
Solution Approach 1:
By merging high-speed data and power supply configuration data into a single serial link, the patent reduces the physical space required for connectors and connection infrastructure. This consolidation allows for thinner device designs while maintaining connection reliability through proper signal integrity management.
3Device complexity
If a single serial communication link is used for both high-speed data and power supply configuration data, then device complexity is reduced, but data transmission reliability may worsen
Solution Approach 1:
The data communication circuit segments and multiplexes different data types (high-speed data and power supply configuration data) into a structured serial format. This segmentation allows proper timing and protocol management for each data type while transmitting them over a single link, maintaining reliability through organized data separation.
Solution Approach 2:
The data communication circuit acts as an intermediary that manages the multiplexing and demultiplexing of different data types. It provides protocol control and signal management to ensure that high-speed data and power supply configuration data are properly separated and transmitted without interference, maintaining reliability despite using a single link.
