Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If millimeter-wave antenna is integrated into laptop or tablet computer, then device portability is improved, but signal attenuation increases and space for antenna placement is limited
Solution Approach 1:
The patent transitions from two-dimensional planar antenna designs to three-dimensional waveguide structures. The waveguide extends vertically from the device casing, utilizing the third dimension to achieve longer antenna effective length and better signal transmission without increasing the device's footprint area.
Solution Approach 2:
The millimeter-wave communication system is divided into separate functional modules: the electronic device contains the waveguide connection port and communication module, while the expansion device contains the millimeter-wave antenna. This segmentation allows each component to be optimized independently and connected via waveguide.
2Device complexity
If millimeter-wave antenna is integrated into laptop or tablet computer, then device integration is improved, but antenna placement space is limited
Solution Approach 1:
The waveguide structure exploits the vertical dimension by extending the antenna element perpendicular to the device casing surface. This allows the antenna to achieve greater effective length and radiation aperture without consuming additional planar space on the device surface.
Solution Approach 2:
The waveguide connection port serves as an intermediary component that bridges the electronic device and the expansion device containing the millimeter-wave antenna. This intermediary enables external antenna placement while maintaining integrated system functionality.
3Reliability
If waveguide connection ports are used to form external waveguide, then signal transmission quality is improved, but device structure complexity increases
Solution Approach 1:
The waveguide connection port is designed with multi-functionality: it serves as both a structural component of the device casing and as an electromagnetic wave transmission interface. This dual function reduces the need for separate dedicated waveguide components, thereby simplifying the overall structure while maintaining signal transmission quality.

When the electronic device is fastened on the expansion device, the first waveguide connection port and the second waveguide connection port form a waveguide to transmit and receive the millimeter-wave signals. Therefore, attenuation of the millimeter-wave signals is avoided.
