Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate antenna panels are used for transmit and receive operations, then signal isolation and alignment precision are improved, but device size and structural complexity increase
Solution Approach 1:
The patent combines transmit and receive antenna panels into a single integrated antenna panel that contains both transmit antenna elements and receive antenna elements. This merging eliminates the need for separate panels while maintaining signal isolation through frequency-based separation and independent beamforming control, thereby reducing structural complexity without compromising reliability
Solution Approach 2:
The integrated antenna panel serves multiple functions simultaneously - it performs both transmit and receive operations, and can independently form separate beams for each function. The antenna elements can be dynamically configured for different operations, making the single panel universal for both transmission and reception tasks
2Measurement precision
If separate antenna panels are used for transmit and receive operations, then alignment precision is improved, but device size increases
Solution Approach 1:
The patent merges transmit and receive antenna panels into one integrated panel, reducing the overall device area occupied by antenna structures. The integrated panel maintains precise alignment capability through electronic beamforming that can independently control the orientation and focusing of transmit and receive beams without requiring separate physical panels
3Reliability
If separate processing elements are used for transmit and receive operations, then signal processing quality is improved, but device complexity and cost increase
Solution Approach 1:
The patent employs a single processing element that handles both transmit and receive signal processing through dynamic configuration. The processing element can be programmed to perform different functions for transmit and receive operations, eliminating the need for separate dedicated processing hardware while maintaining signal processing quality through software-defined beamforming and signal manipulation
4Measurement precision
If separate antenna panels are used for transmit and receive operations, then beam alignment accuracy is improved, but signal delay and coordination complexity increase
Solution Approach 1:
The patent combines transmit and receive antenna panels into a single integrated panel with unified processing, eliminating the coordination delays associated with separate panels. The integrated structure allows simultaneous control of transmit and receive beams through a single processing element, reducing signal delay and synchronization complexity while maintaining beam alignment accuracy through electronic phase control
