Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If beam sweeping is performed without feedback information, then the system structure remains simple, but sensing performance is impaired due to inefficient beam direction selection
Solution Approach 1:
The patent implements a feedback mechanism where the sensing signal receiver provides feedback information to the transmitter about optimal beam directions. This feedback loop enables the transmitter to adjust beam directions based on actual sensing performance, resolving the contradiction by improving sensing reliability through intelligent beam selection while maintaining manageable system complexity through structured information exchange.
2Measurement precision
If feedback information is transmitted for beam optimization, then sensing accuracy is enhanced, but additional communication overhead is introduced
Solution Approach 1:
The patent extracts only the essential feedback information needed for beam optimization, such as beam direction indicators and signal quality metrics, while filtering out unnecessary data. This selective information extraction enables enhanced sensing accuracy through targeted feedback while minimizing communication overhead by transmitting only critical parameters for beam management.
3Strength
If multiple beams are used for sensing signal transmission, then signal reception strength is improved, but the complexity of beam management increases
Solution Approach 1:
The patent segments the beam management task by dividing the sensing area into multiple discrete beam directions and assigning specific feedback handling procedures to each beam segment. This segmentation enables the system to manage multiple beams systematically through modular processing, improving signal reception strength through diverse beam coverage while reducing overall management complexity through structured organization.
