Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If more antenna arrays are laid out to support 5G and MIMO technologies, then the wireless communication capability is improved, but the mounting space required increases, making the electronic device heavier and thicker
Solution Approach 1:
The patent transitions from planar antenna layout to three-dimensional立体 layout by placing antenna arrays on both the front surface and back surface of the substrate. This dimensional change allows multiple antenna arrays to coexist without increasing the device's planar footprint, thereby supporting enhanced wireless communication capabilities while maintaining a compact form factor.
Solution Approach 2:
The patent embeds multiple antenna arrays within a compact substrate structure by utilizing both surfaces and the thickness dimension. The front and back antenna arrays are nested in close proximity, with the back antenna array positioned on the opposite surface of the front antenna array, maximizing space utilization without requiring additional mounting area.
2Adaptability or versatility
If dual polarization is implemented on a single antenna array, then the antenna functionality is improved, but the mounting space still increases, hindering lighter and thinner device development
Solution Approach 1:
Instead of expanding dual-polarization antennas in the planar direction, the patent utilizes the thickness dimension by placing complementary polarization antenna arrays on opposite surfaces of the substrate. This allows dual-polarization functionality to be achieved without increasing device thickness, as the stacked configuration maintains a compact profile.
