Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard UWB signal transmission is used for self-localization, then the system is simple to implement, but the positional accuracy is insufficient
Solution Approach 1:
The patent applies dynamics by enabling the transmitter/receiver to switch between multiple operating modes (omnidirectional and directional antenna configurations) based on measurement requirements. This allows the system to adapt its complexity dynamically - using simple omnidirectional mode for basic operations and switching to directional modes when higher accuracy is needed for specific distance measurements.
Solution Approach 2:
The patent changes physical parameters of the radio signal transmission system by providing multiple operating modes with different antenna configurations, polarizations, and transmission characteristics. These parameter changes enable optimization of distance measurement accuracy for specific spatial relationships between equipment without requiring complete system redesign.
2Measurement precision
If multiple operating modes with different antennas are used to improve measurement accuracy, then positional accuracy improves, but device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing a single transmitter/receiver unit that can operate in multiple modes (omnidirectional and directional antenna configurations) depending on the measurement requirements. This universal design allows one device to perform both simple and complex measurements without requiring separate specialized equipment for each function.
Solution Approach 2:
The system dynamically selects appropriate operating modes based on the measurement task at hand, switching between simple omnidirectional mode for general operations and complex directional modes only when high-accuracy distance measurement is required, thereby avoiding unnecessary complexity in routine operations.
3Measurement precision
If distance measurements are attempted for all equipment pairs, then positional accuracy improves, but measurement time increases
Solution Approach 1:
The patent performs preliminary identification of equipment pairs that require enhanced measurement by detecting unmeasured distances in the list of equipment relationships. This preliminary analysis allows the system to prioritize measurements that are most critical for position accuracy calculation, avoiding unnecessary measurements for already-sufficient pairs.
Solution Approach 2:
The measurement process is made dynamic by selectively activating different operating modes based on real-time needs. The system monitors which distance measurements are missing and only activates complex directional transmission modes when specifically needed to fill gaps in the measurement data, rather than continuously operating in high-complexity mode.

Enhances the accuracy of positional calculations by detecting and measuring previously unmeasured distances, thereby improving the precision of equipment location through adaptive radio signal characteristics and multiple carrier frequencies.
Implementation Method 1
The distance measurement between the signal emitting equipment and the signal receiving equipment is obtained by calculation from the time of flight (the time elapsed between the moment of signal emission, determinable by the receiving equipment from the time information, and the reception of the signal by the receiving equipment) and the speed of propagation of the signal in the ambient medium
Implementation Method 2
the time of flight (the time elapsed between the moment of signal emission, determinable by the receiving equipment from the time information, and the reception of the signal by the receiving equipment) and the speed of propagation of the signal in the ambient medium
