Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If high gain antenna systems are used to improve directional capabilities and radiation patterns, then antenna gain is improved, but manufacturing complexity and cost increase
Solution Approach 1:
The antenna system is divided into multiple identical or similar antenna elements arranged in an array configuration. Each element has a simplified structure that is easy to manufacture, while the collective array achieves high gain through constructive interference of electromagnetic waves from multiple elements. This segmentation allows standardized production of individual elements followed by modular assembly into the complete antenna system.
Solution Approach 2:
Multiple antenna elements are combined in a structured array to achieve high gain performance. The individual elements work together cooperatively, with their radiation patterns combining through proper phasing and spacing to produce the desired directional radiation pattern and improved gain without requiring each individual element to be complex.
2Reliability
If rugged designs are used for portable systems, then reliability is improved, but manufacturing cost increases
Solution Approach 1:
The antenna system is segmented into multiple identical modular elements that can be manufactured using standardized processes. This modularity enables consistent quality control and simplified assembly, reducing overall manufacturing cost while maintaining reliability through the ruggedized modular construction of each individual element.
3Length of stationary object
If high gain antenna systems are used for extended distances and high WiFi density areas, then communication range is improved, but device complexity increases
Solution Approach 1:
The antenna system uses multiple identical or similar antenna elements arranged in an array to achieve high gain for extended communication ranges. Each individual element maintains a simple, manageable structure that is easy to design and manufacture, while the collective array configuration provides the necessary directional capabilities and extended range through constructive interference of electromagnetic waves.
Solution Approach 2:
The antenna system achieves high gain and extended communication range by transitioning from a single-element to a multi-element array configuration. This dimensional change from one to many elements allows the system to achieve the desired performance metrics through spatial arrangement and phase control rather than through complex individual element design.
