Engineering Contradiction Analysis
1Volume of moving object
If USB-A interface with circuit board and parallel antenna configuration is used, then wireless signal transmission function is achieved, but device dimensions become too large (greater than 12 mm by 4.5 mm with 18 mm depth)
Solution Approach 1:
The patent transitions from the traditional USB-A parallel configuration to USB Type-C's perpendicular insertion orientation. The circuit board is positioned perpendicular to the insertion direction, and the antenna radiator is arranged orthogonal to the circuit board, utilizing three-dimensional space more efficiently to reduce the device's footprint while maintaining functionality
Solution Approach 2:
The antenna radiator is integrated within the housing structure, with its projection overlapping the circuit board's projection. This nested arrangement allows both components to occupy overlapping spatial volumes, significantly reducing the overall device dimensions while preserving both wireless transmission and USB Type-C interface capabilities
2Length of stationary object
If circuit board and antenna are disposed in parallel configuration, then electrical connection is simplified, but device depth exceeds 18 mm
Solution Approach 1:
The patent changes the spatial relationship from parallel (two-dimensional arrangement) to orthogonal (three-dimensional arrangement). The antenna radiator is positioned perpendicular to the circuit board, with its projection overlapping the circuit board's projection, thereby reducing device depth while managing complexity through standardized orthogonal mounting
