Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple antennas are used to improve position determination accuracy, then measurement precision improves, but device complexity and difficulty of mounting increase
Solution Approach 1:
The patent uses a second external electronic device as an intermediary to provide additional direction information. Instead of requiring multiple antennas in one device, the system collaborates with another device to obtain the necessary bearing data from multiple perspectives, thereby achieving accurate position determination without increasing the antenna count in the primary device.
Solution Approach 2:
The patent transitions from a single-device multi-antenna approach to a multi-device collaboration approach. By adding the dimension of spatial distribution across multiple external devices, the system obtains direction information from different locations, enabling accurate triangulation without requiring multiple antennas within a single miniaturized device.
2Measurement precision
If multiple antennas are mounted to achieve accurate position estimation, then measurement precision improves, but ease of manufacture deteriorates
Solution Approach 1:
The patent employs a second external electronic device as a manufacturing intermediary. This external device provides the additional directional measurements needed for accurate position estimation, eliminating the need to physically mount multiple antennas in the primary device and thus simplifying the manufacturing process.
Solution Approach 2:
The patent extracts the function of providing multiple bearing measurements from the primary device's antenna system and relocates it to external electronic devices. This separation allows the primary device to maintain a simple antenna configuration while still achieving accurate position estimation through collaborative measurement.
3Measurement precision
If wireless communication signals from multiple antennas are used, then position determination accuracy improves, but device complexity increases
Solution Approach 1:
The patent uses external electronic devices as intermediaries to collect and process wireless communication signals from multiple locations. The second external device captures signals and provides direction information, reducing the signal processing burden on the primary device while maintaining high position determination accuracy.
Solution Approach 2:
The patent shifts the signal collection dimension from multiple antennas within one device to multiple external devices in different spatial locations. This dimensional change simplifies the primary device's signal processing requirements while achieving the same measurement precision through distributed signal acquisition.
