Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple antennas are integrated into a limited volume, then signal receiving capability is enhanced, but device size and weight increase
Solution Approach 1:
The patent combines multiple antenna radiators (first antenna radiator on the frame, second antenna radiator on the support plate, and third antenna radiator on the circuit board) into a single integrated structure. This merging of multiple antenna functions into one compact device enhances signal receiving capability across different frequencies and orientations without requiring separate antenna assemblies, thus improving versatility while controlling overall device volume.
Solution Approach 2:
The patent implements a nested arrangement where the support plate is disposed within the accommodation space of the frame, and the circuit board is positioned within the accommodation space as well. The third antenna radiator is integrated onto the circuit board surface. This nested configuration allows multiple antenna radiators to occupy overlapping or adjacent spatial regions, maximizing space utilization and enabling multiple antennas in a limited volume.
2Adaptability or versatility
If multiple antennas are integrated into a limited volume, then signal receiving capability is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent divides the antenna system into distinct segments: the first antenna radiator integrated on the frame, the second antenna radiator on the support plate, and the third antenna radiator on the circuit board. Each segment can be manufactured and positioned independently, then assembled together. This segmentation reduces manufacturing complexity by allowing modular production and assembly of multiple antenna radiators rather than creating one complex integrated antenna structure.
Solution Approach 2:
The frame serves multiple functions: it provides structural support for the device and simultaneously integrates the first antenna radiator for signal reception. The support plate also serves dual purposes as a structural element and a mounting platform for the second antenna radiator. This multi-functionality reduces the number of separate components needed, simplifying the overall manufacturing process while maintaining multiple antenna capabilities.
