Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional antenna designs are used in MIMO systems, then the system can transmit and receive wireless signals, but power is wasted and system performance suffers due to non-uniform user distributions and environmental factors
Solution Approach 1:
The patent applies local quality by configuring different dipole antennas with specific polarization directions and notch orientations tailored to their positions in the array. Each antenna element is optimized for its local radiation sector, creating non-uniform but optimized radiation characteristics that match the spatial distribution of users and environmental conditions, thereby improving transmission throughput while reducing power waste.
Solution Approach 2:
The patent implements dynamics through the switch device that enables dynamic selection and configuration of dipole antennas based on real-time communication conditions. The system can adaptively activate specific antennas with appropriate polarization and notch configurations to match changing user distributions and environmental factors, optimizing performance while minimizing power consumption.
2Productivity
If conventional antenna designs are used, then the system structure is simple, but frequency band utilization and transmission efficiency are poor
Solution Approach 1:
The patent applies segmentation by dividing the antenna system into multiple independent dipole antenna elements, each with specific polarization directions and notch configurations. This segmentation allows each element to be optimized for particular frequency bands and radiation patterns, improving overall transmission efficiency while maintaining manageable system complexity through modular architecture.
Solution Approach 2:
The patent implements universality by designing dipole antennas that can operate across multiple frequency bands through their dual-radiator structures with notches. Each antenna element serves multiple functions by supporting different frequency ranges and polarization directions, improving frequency band utilization without proportionally increasing device complexity.
3Adaptability or versatility
If dipole antennas with different notch directions are used, then radiation bandwidth and gain are improved, but the antenna structure becomes more complex
Solution Approach 1:
The patent applies asymmetry by configuring dipole antennas with notches oriented in different directions rather than uniform symmetric arrangements. This asymmetric configuration creates complementary radiation patterns that together provide wider overall coverage and higher gain in specific directions, improving adaptability while the modular dipole structure keeps individual element complexity manageable.
