Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single antenna is used for signal reception, then the device complexity is reduced, but the localization precision deteriorates
Solution Approach 1:
The antenna system is segmented into a first antenna and a second antenna, with each antenna receiving signals independently. The processing module segments the signal processing task by separately processing signals from each antenna and then combining the results to determine channel information and location, thereby achieving high localization precision without requiring a complex integrated antenna system.
Solution Approach 2:
The processing module acts as an intermediary that receives signals from both antennas, processes them separately to determine channel information, and then combines this information to calculate the location of the communication device. This intermediary processing step enables precise localization while keeping the antenna configuration relatively simple.
2Measurement precision
If mechanical rotation is implemented to maintain accurate channel, then the localization precision is improved, but the device complexity and mechanical reliability worsen
Solution Approach 1:
The patent replaces the mechanical rotation system with a signal processing-based solution. Instead of physically rotating the antenna to maintain accurate channel, the system uses a processing module to receive signals from multiple antennas simultaneously and determine channel information through signal processing, thereby eliminating mechanical complexity while maintaining or improving channel accuracy.
Solution Approach 2:
The system transitions from a static single-antenna configuration to a dynamic multi-antenna system where signals from multiple antennas are processed in real-time. The processing module dynamically determines channel information based on signals from both antennas, allowing the system to adapt to communication device movements without mechanical rotation.
3Measurement precision
If phase errors are present in signal processing, then the processing simplicity is maintained, but the localization precision deteriorates
Solution Approach 1:
The processing module implements a feedback mechanism where signals from both antennas are processed to determine channel information, which is then used to calculate the location of the communication device. The system continuously receives signals, processes them to update channel information, and refines location determination, thereby compensating for phase errors through iterative processing while maintaining reasonable system complexity.
