Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If distance measurement results are acquired from multiple communication devices, then position estimation accuracy is improved, but temporal correspondence and discrimination of measurement results become difficult
Solution Approach 1:
The patent introduces counter information as an intermediary element that mediates between multiple distance measurement results and the control device. Each distance measurement result is associated with counter information that serves as a unique identifier, enabling the control device to distinguish and correctly correlate measurements from different communication devices and time points without losing temporal correspondence information
Solution Approach 2:
The control device transmits counter information to communication devices, which then use this counter information to associate with their distance measurement results. This feedback mechanism ensures that measurement results are returned with the correct identifying information, maintaining temporal correspondence and enabling accurate position estimation
2Measurement precision
If distance measurement results are acquired from multiple communication devices, then position estimation accuracy is improved, but processing complexity increases
Solution Approach 1:
The counter information acts as an intermediary that simplifies the processing of multiple distance measurement results. By associating each measurement with a unique counter value, the control device can systematically manage and process measurements from multiple communication devices without overwhelming complexity, enabling accurate position estimation through organized data handling
