Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas with different frequency bands and standards are configured to meet increasing communication demands, then the network coverage and signal transmission capability are improved, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple antennas (first antenna and second antenna with different frequency bands and standards) into a single integrated antenna system mounted on one support structure. The antennas share common mounting resources, detection apparatus, and control mechanisms, thereby achieving multi-band and multi-standard network coverage while reducing overall system complexity and space occupation compared to separate antenna installations.
Solution Approach 2:
The antenna system is designed with universal functionality to support multiple frequency bands and communication standards simultaneously. The first antenna and second antenna can operate across different bands (e.g., sub-6GHz and millimeter wave), and the shared detection apparatus and control unit provide universal measurement and adjustment capabilities for all antenna elements, eliminating the need for separate dedicated systems for each band or standard.
2Adaptability or versatility
If the quantity of antennas is increased to meet multiple frequency bands and standards, then the communication performance is improved, but the installation space and platform resources are consumed
Solution Approach 1:
The patent implements a nested arrangement where the second antenna is rotatably mounted on the support structure that also holds the first antenna. The detection apparatus and control unit are integrated within the compact antenna assembly. This nesting approach allows multiple antennas to occupy overlapping or adjacent spatial volumes, significantly reducing the total installation footprint compared to side-by-side placements.
Solution Approach 2:
The patent transitions from two-dimensional planar arrangement to three-dimensional spatial utilization by mounting the second antenna on a rotatable mechanism that allows it to adjust its orientation and position in space. This vertical and angular dimensionality enables multiple antennas to be stacked or arranged in different spatial planes, maximizing the use of limited installation space while maintaining signal isolation and performance.
3Measurement precision
If separate detection apparatuses are used for each antenna to measure azimuths, then the measurement accuracy is improved, but the device complexity and cost increase
Solution Approach 1:
The patent employs a single detection apparatus that serves multiple functions: it detects the azimuth of the first antenna when in its initial position, and subsequently detects the azimuth of the second antenna after rotation, or detects relative angle changes between antennas. This universal detection device eliminates the need for multiple separate azimuth sensors, reducing system complexity and cost while maintaining measurement precision through sequential or differential measurement approaches.
Solution Approach 2:
The detection apparatus acts as an intermediary that measures relative angle changes between the first antenna and second antenna. By detecting the rotation angle of the second antenna relative to the first antenna's reference position, the system indirectly obtains the second antenna's azimuth without requiring a separate absolute azimuth sensor for each antenna element, thereby simplifying the detection system while preserving measurement accuracy.
