Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single RF chip is used to support multiple paired wireless devices, then device complexity is reduced, but the polling rate and performance of each wireless device deteriorate due to sequential processing limitations
Solution Approach 1:
The system segments the RF processing function by using multiple RF chips (at least two) instead of a single RF chip. Each RF chip is individually paired with a specific wireless device and operates on at least one same frequency channel, enabling parallel processing of multiple wireless devices simultaneously without limiting the polling rate of any individual device.
2Productivity
If multiple RF chips are used to support multiple paired wireless devices simultaneously, then the polling rate and performance of each wireless device improve, but device complexity increases
Solution Approach 1:
The power divider serves as a universal component that enables multiple RF chips to share a common antenna module. The power divider distributes the RF signals from the antenna module to multiple RF chips, allowing them to operate simultaneously without requiring separate antenna modules for each RF chip, thus reducing overall system complexity while maintaining high polling rates.
3Adaptability or versatility
If multiple RF chips share a common antenna module through a power divider, then resource utilization improves and device complexity is managed, but signal interference and power coupling may occur between RF chips
Solution Approach 1:
The power divider acts as an intermediary component between the antenna module and multiple RF chips. It distributes RF signals to different RF chips while providing isolation between them, preventing direct power coupling and interference between RF chips operating on the same or overlapping frequency channels. This mediator role allows multiple RF chips to share the antenna resource efficiently without mutual interference.
