Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-frequency RF signals are transmitted for 5G and millimeter wave communications, then data traffic capacity is improved, but signal loss due to absorption increases
Solution Approach 1:
The antenna system is divided into multiple patch antennas arranged in an array configuration, with each element contributing to the overall signal. This segmentation allows for beamforming techniques that concentrate energy in specific directions, improving signal strength and reducing loss in 5G and millimeter wave communications
Solution Approach 2:
The patent implements a multi-layered antenna structure where patch antennas are arranged in multiple levels or tiers. This nested configuration enables three-dimensional beamforming and provides redundancy, allowing the system to maintain high data traffic capacity while compensating for signal absorption losses through spatial diversity
2Reliability
If antenna gain is increased to compensate for signal loss, then communication quality is improved, but device complexity increases
Solution Approach 1:
The patch antenna elements serve multiple functions simultaneously: they act as radiating elements, provide beamforming capability, enable spatial diversity, and support both transmission and reception. This multi-functionality allows the system to achieve high communication quality without proportionally increasing complexity
Solution Approach 2:
The patent combines multiple antenna functions into a unified patch antenna array structure. The feed networks, radiating elements, and grounding structures are integrated into a single system design, reducing the overall complexity compared to using separate systems for each function while maintaining high gain and communication quality
3Power
If effective isotropic radiated power is secured through special technologies, then signal strength is improved, but manufacturing complexity increases
Solution Approach 1:
The patent achieves high effective isotropic radiated power by optimizing geometric parameters of the patch antennas including size, spacing, shape, and positioning. By carefully controlling these parameters, the system maximizes radiation efficiency and power output using standard manufacturing processes, avoiding the need for complex specialized fabrication techniques
