Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If satellite communication function module is integrated as independent chip, then satellite communication function can be provided, but product integration is low and board-level costs are high
Solution Approach 1:
The patent merges the satellite communication function module with the wireless communication function module by integrating their radio frequency receive circuits on the same chip. Specifically, the first radio frequency receive circuit processes satellite communication signals while the second radio frequency receive circuit processes wireless communication signals, both circuits being integrated on a single chip rather than separate independent chips, thereby improving product integration and reducing board-level complexity
Solution Approach 2:
The patent implements multi-functionality by designing a unified communication module that can perform both satellite communication and wireless communication functions. The baseband circuit is configured to handle both satellite communication baseband signals and wireless communication baseband signals, allowing a single integrated chip to serve multiple communication purposes rather than requiring separate dedicated chips for each function
2Adaptability or versatility
If satellite communication function module is integrated as independent chip, then satellite communication function can be provided, but board-level costs are high
Solution Approach 1:
The patent reduces board-level costs by merging the satellite communication and wireless communication function modules onto a single integrated chip. This eliminates the need for separate independent chips and their associated board-level components, connectors, and cabling, thereby reducing manufacturing complexity and costs
Solution Approach 2:
The patent creates a universal communication module that provides both satellite communication and wireless communication functions through a single integrated chip design. This multi-functional approach eliminates redundant components and reduces overall board-level costs compared to using separate dedicated chips for each communication function
3Adaptability or versatility
If multiple function modules work simultaneously, then comprehensive communication capability is achieved, but mutual interference exists
Solution Approach 1:
The patent segments the radio frequency receive circuits into distinct first and second radio frequency receive circuits, where the first circuit is dedicated to satellite communication signals and the second circuit is dedicated to wireless communication signals. This segmentation allows both functions to operate simultaneously without mutual interference by providing separate signal processing paths
Solution Approach 2:
The patent applies local quality by assigning different functional characteristics to different parts of the integrated chip. The first radio frequency receive circuit is optimized for satellite communication signal processing while the second radio frequency receive circuit is optimized for wireless communication signal processing, allowing each region to handle its specific signal type with appropriate local optimizations
4Adaptability or versatility
If multiple function modules work simultaneously, then comprehensive communication capability is achieved, but joint control cannot be implemented
Solution Approach 1:
The patent merges the control functions by integrating both satellite communication and wireless communication baseband circuits on the same chip, enabling joint control. The baseband circuit can simultaneously process and control both satellite communication baseband signals and wireless communication baseband signals, allowing coordinated operation and unified control of both communication functions

AI summary
A terminal device includes a first radio frequency front-end circuit, a second radio frequency front-end circuit, an input circuit, a first radio frequency receive circuit, a second radio frequency receive circuit, a satellite communication baseband circuit, and a wireless communication baseband circuit. The input circuit receives a first radio frequency signal and a second radio frequency signal, and outputs both of the radio frequency signals through a same branch. One of the first radio frequency receive circuit and the second radio frequency receive circuit processes the received first radio frequency signal into a first baseband signal, and sends the first baseband signal to the satellite communication baseband circuit. The other of the first radio frequency receive circuit and the second radio frequency receive circuit processes the received second radio frequency signal into a second baseband signal, and sends the second baseband signal to the wireless communication baseband circuit.
