Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional multi-band antennas are used, then multi-band communication capability is achieved, but the antenna size becomes large and bulky
Solution Approach 1:
The antenna system is divided into multiple independent antenna elements, each designed to operate at specific frequency bands. These segmented antenna elements are arranged in a compact configuration within the nozzle cap housing, allowing multi-band functionality without requiring a single large antenna structure.
Solution Approach 2:
Multiple antenna elements are nested or closely integrated within the limited space of the nozzle cap housing. The antenna elements are positioned in a compact arrangement that allows them to coexist in a small volume while maintaining their respective frequency band operations.
2Adaptability or versatility
If antenna elements are added for multi-band operation, then communication versatility improves, but device complexity increases
Solution Approach 1:
The antenna elements are designed with universal mounting structures and standardized connections that simplify integration. The common housing and mounting mechanism provide a universal platform that reduces the overall complexity despite having multiple antenna elements for different frequency bands.
