Engineering Contradiction Analysis
1Volume of moving object
If the feed network is deployed on a circuit board or metal plate with planar layout, then the signal transmission performance can be maintained, but the area occupied increases and miniaturization cannot be achieved
Solution Approach 1:
The patent transitions from traditional two-dimensional planar layout on circuit boards to three-dimensional spatial arrangement using support frames. Functional units are positioned at different heights and depths, utilizing vertical space to reduce the horizontal footprint while maintaining signal transmission capabilities. This dimensional transformation enables miniaturization without compromising manufacturing feasibility.
2Reliability
If more radiating elements are integrated in the antenna array to improve signal transmission performance, then the antenna array capability is enhanced, but the feed network area needs to be increased
Solution Approach 1:
By arranging functional units in three-dimensional space on support frames rather than spreading them out on a two-dimensional circuit board, the patent accommodates increased numbers of radiating elements without proportionally increasing the overall area. The vertical stacking and spatial distribution of functional units enable higher integration density.
3Reliability
If the feed network is designed with increased complexity to support more radiating elements, then the signal transmission performance improves, but the area required for deployment increases
Solution Approach 1:
The three-dimensional support frame structure allows complex feed network designs to be compacted into smaller volumes by utilizing vertical and depth dimensions. Functional units are positioned in space rather than only on a plane, reducing the horizontal spread while accommodating increased functional complexity.
Solution Approach 2:
The support frame structure enables nested arrangement of functional units at different levels and depths. Smaller functional units are positioned within the three-dimensional envelope created by the support frame, creating a compact hierarchical structure that reduces overall volume while maintaining complexity.
