Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional microstrip printed circuit topology is used for power dividers, then good electrical performance and isolation between channels are achieved, but the circuit becomes bulky and complex to integrate into smart garments
Solution Approach 1:
The power divider is segmented into a single integrated block with three output channels, eliminating the need for multiple separate dividing blocks and reducing overall circuit complexity while maintaining electrical performance
Solution Approach 2:
Multiple functional elements (input channel, three output channels, and isolation mechanisms) are merged into a single planar circuit block, simplifying the overall structure and making it suitable for integration into smart garments
2Power
If conventional multi-block power divider design is used, then adequate power distribution is achieved, but the footprint and integration difficulty increase for smart clothing applications
Solution Approach 1:
The circuit is designed in a uniplanar configuration, confining all transmission lines and components to a single plane, which minimizes the footprint and enables flexible integration into wearable applications
Solution Approach 2:
The three output channels are arranged in a nested or compact configuration around the input channel, optimizing space utilization and reducing the overall circuit footprint
