Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ranging control messages are transmitted to determine time intervals and distances between electronic devices, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The ranging process is segmented into distinct phases with specific message types: ranging control messages initiate the process, ranging start messages begin actual measurement, and ranging response messages complete the exchange. Each message type has a specific function, dividing the complex ranging protocol into manageable segments that improve measurement precision while organizing device complexity.
Solution Approach 2:
Ranging control messages are transmitted beforehand to establish timing parameters and measurement configurations before actual distance measurement begins. This preliminary action allows devices to synchronize their clocks and prepare measurement windows, improving measurement precision by ensuring both devices are ready and synchronized before the actual ranging occurs.
2Adaptability or versatility
If multiple cast modes (unicast, broadcast, multicast) are supported for data transmission, then adaptability is improved, but device complexity increases
Solution Approach 1:
The ranging and communication protocol is designed with universal message structures that can operate in multiple cast modes (unicast, broadcast, multicast). The same basic message types and exchange procedures work across all three modes, allowing a single protocol implementation to provide adaptability for different communication scenarios without requiring separate protocols for each mode, thus managing device complexity while improving versatility.
