Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the transmission incidence of beacon signal is increased to improve position detection speed, then position detection speed is improved, but average power consumption of transmitter increases
Solution Approach 1:
The beacon signal transmission is segmented into two distinct types: first beacon signals with low transmission strength and high transmission incidence, and second beacon signals with high transmission strength and low transmission incidence. This segmentation allows the system to achieve high position detection speed through frequent low-power first beacon signals while using second beacon signals for comprehensive position detection, thereby resolving the contradiction between detection speed and power consumption.
Solution Approach 2:
The system dynamically changes transmission parameters by switching between two beacon signal modes. First beacon signals use low transmission strength and high transmission incidence parameters, while second beacon signals use high transmission strength and low transmission incidence parameters. This parameter change strategy enables the transmitter to optimize between speed and power consumption based on different operational requirements.
