Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different radiation elements are designed for different frequency bands, then the radiation element can work well in its corresponding frequency band, but the device complexity increases and costs increase due to needing multiple elements
Solution Approach 1:
The patent applies universality by designing a single radiation element that can operate across multiple frequency bands. The radiation element is designed with specific geometric parameters and bandwidth extension structures that enable it to function effectively in both first and second frequency bands, eliminating the need for separate radiation elements for different bands.
Solution Approach 2:
The patent applies segmentation by dividing the radiation element into a basic radiation element and one or more bandwidth extension structures. The bandwidth extension structures are further segmented into first and second bandwidth extension structures, each with specific geometric parameters. This segmentation allows each part to contribute to different frequency band operations while maintaining overall integration.
2Device complexity
If a single radiation element is used for broadband operation, then device complexity is reduced, but the radiation element cannot work well across different frequency bands leading to amplitude and phase distribution inconsistency
Solution Approach 1:
The patent applies local quality by optimizing specific geometric parameters of different parts of the radiation element for different frequency bands. The basic radiation element has parameters optimized for the first frequency band, while the bandwidth extension structures have parameters optimized for the second frequency band. This localized optimization ensures consistent amplitude and phase distribution across both bands.
Solution Approach 2:
The patent applies parameter changes by adjusting geometric parameters such as length, width, and positioning of the bandwidth extension structures relative to the basic radiation element. These parameter changes enable the radiation element to maintain consistent performance across different frequency bands by tuning the electromagnetic characteristics.
3Reliability
If high gain radiation elements are used, then radiation performance is improved, but the radiation element cannot operate effectively in broadband leading to interference between adjacent base stations
Solution Approach 1:
The patent applies dynamics by designing the bandwidth extension structures with geometric parameters that can be adjusted to adapt to different frequency bands. The structures include configurable parameters such as length, width, and positioning that allow the radiation element to dynamically adapt its electromagnetic characteristics to operate effectively across both first and second frequency bands, preventing interference.
