Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna arrays are designed to achieve high gain and beam-forming capabilities, then signal transmission quality and service range are improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent changes the dielectric constant parameter by introducing high dielectric constant pieces (second dielectric constant) into the dielectric layer (first dielectric constant). This parameter modification enables the antenna to achieve higher radiation gain and improved signal transmission quality without increasing the overall antenna structure complexity, as the gain enhancement is achieved through material property adjustment rather than structural expansion.
Solution Approach 2:
The patent employs composite materials by combining dielectric pieces with different dielectric constants within the same antenna structure. The dielectric layer contains multiple dielectric pieces having different dielectric constants, forming a composite material system that optimizes radiation characteristics and achieves high gain performance while maintaining a compact antenna array design.
2Reliability
If dielectric pieces with different dielectric constants are introduced to enhance radiation gain, then antenna performance is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the dielectric layer into multiple dielectric pieces, each with different dielectric constants, arranged in specific patterns. This segmentation allows for modular manufacturing where different dielectric pieces can be prepared separately and then assembled into the antenna structure, reducing overall manufacturing complexity compared to creating a single complex dielectric component.
Solution Approach 2:
The patent applies local quality by placing dielectric pieces with specific dielectric constants at specific locations within the dielectric layer. Each dielectric piece is positioned to optimize local electromagnetic field distribution, and the manufacturing process can be simplified by treating each location's dielectric requirement independently rather than requiring uniform material properties throughout.
