Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are added to meet 5G communication requirements, then communication performance is improved, but device size increases
Solution Approach 1:
The patent transitions from planar antenna arrangement to three-dimensional spatial arrangement by introducing an antenna stand that elevates the antenna structure above the circuit board. This vertical dimension allows multiple antennas to be positioned in space without increasing the device's footprint, resolving the contradiction between accommodating multiple antennas and maintaining compact device size.
Solution Approach 2:
The antenna structure is nested within the device housing space by utilizing the vertical dimension between the circuit board and the device outer shell. The antenna stand anchors the elevated antenna structure to the circuit board while positioning it within the available internal volume, effectively nesting the antenna system within the device's three-dimensional envelope without requiring additional external space.
2Reliability
If antenna structure is elevated to improve radiation performance, then antenna performance is improved, but assembly complexity increases
Solution Approach 1:
The antenna system is segmented into distinct functional modules: the circuit board, the antenna stand, and the antenna structure. This segmentation allows each component to be manufactured and tested independently, then assembled together through standardized interfaces, reducing overall assembly complexity despite the three-dimensional configuration.
Solution Approach 2:
The antenna stand serves as an intermediary component that bridges the circuit board and the elevated antenna structure. It provides mechanical support, positioning, and electrical connection functionality, simplifying the assembly process by consolidating multiple functions into a single intermediate element rather than requiring complex direct mounting solutions.
