Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single radiation unit is used on the first base substrate, then the structure is simple, but the radiation area is small and radiation efficiency is low
Solution Approach 1:
The patent introduces a second base substrate stacked vertically above the first base substrate, creating a three-dimensional layered structure. The second radiation unit on the second base substrate operates in a different spatial dimension (vertical stacking), thereby increasing the total radiation area without expanding the planar footprint. This dimensional transition resolves the contradiction by enabling enhanced radiation efficiency while maintaining compact horizontal dimensions.
Solution Approach 2:
The patent implements a nested configuration where the orthographic projection of the second radiation unit overlaps with the orthographic projection of the first radiation unit. This nesting arrangement allows both radiation units to occupy different vertical levels while sharing the same horizontal projection area, effectively multiplying the radiation area within a compact footprint and improving radiation efficiency without significantly increasing device complexity.
2Reliability
If multiple radiation units are added to increase radiation area, then radiation efficiency improves, but device complexity increases
Solution Approach 1:
Instead of placing multiple radiation units side-by-side in the same plane which would increase horizontal area and complexity, the patent stacks radiation units vertically on different base substrates. This vertical dimensionality change allows multiple radiation units to coexist in a compact footprint, improving radiation efficiency while controlling structural complexity through standardized layered construction.
Solution Approach 2:
The patent combines multiple radiation units (first radiation unit on first base substrate, second radiation unit on second base substrate) into an integrated antenna system where they work together as a unified structure. The feeding structures and electrode layers are also merged across layers, creating a coordinated multi-layer system that achieves enhanced radiation efficiency through collaborative operation rather than independent units, thereby managing overall complexity.

Function Achieved in This Case
