Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional communication protocols are used for device-to-device communication, then compatibility and ease of operation are improved, but communication latency increases and productivity deteriorates
Solution Approach 1:
The communication system is segmented into two distinct protocols: a first protocol for device-to-device communication that prioritizes low latency and high productivity, and a second protocol for device-to-network communication that ensures compatibility. This segmentation allows each protocol to be optimized for its specific purpose without compromise.
Solution Approach 2:
The system dynamically selects between different communication protocols based on the communication scenario. The processing circuitry determines whether to use the first protocol (for direct device communication) or the second protocol (for network-mediated communication), enabling adaptive optimization of communication performance.

If a single communication protocol is used for all device communications, then device complexity is reduced, but communication efficiency deteriorates
Solution Approach 1:
The communication device is designed with multi-functionality, supporting both a first communication protocol optimized for device-to-device communication and a second communication protocol for network communication. This universal design enables the device to adapt to different communication scenarios while maintaining high efficiency in each mode.
Solution Approach 2:
The system dynamically selects between different communication protocols based on the communication scenario.
