Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a signal receiver is configured to receive and process satellite signals in an outdoor unit, then signal reception capability is improved, but the ability to distribute signals to multiple indoor units simultaneously is limited
Solution Approach 1:
The signal receiver is divided into multiple functional blocks including amplifiers, band-pass filters, splitters, mixers, and frequency converting blocks that operate in parallel to process different signal components separately, enabling simultaneous signal distribution to multiple indoor units while maintaining reliable reception
2Adaptability or versatility
If signal processing components are added to enable distribution to multiple indoor units, then adaptability is improved, but device complexity increases
Solution Approach 1:
Multiple signal processing functions including amplification, filtering, splitting, frequency conversion, and demodulation are merged into a single integrated circuit chip, reducing device complexity while maintaining the ability to distribute signals to multiple indoor units simultaneously
