Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current RF receivers with parallel channel configurations lack the ability to dynamically reconfigure RF signal distribution efficiently across multiple antennas and channels, limiting their flexibility and dynamic range in receiving and processing RF signals.
Innovation Solution
A multi-input receiver system featuring an input port configuration block (IPCB) with multiple connection modules, power splitters, mechanical diversion and interruption switches, and a configuration block controller, allowing selective configuration into N=1, N=2, N=3, and N=4 configurations to distribute RF signals across multiple antennas and channels, ensuring equivalent power components are transferred to output ports.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed parallel channel configuration is used in RF receivers, then the receiver structure is simple and stable, but the flexibility and dynamic range of RF signal processing are limited
Solution Approach 1:
The patent implements dynamic reconfiguration of RF signal distribution by replacing fixed connections with controllable switching elements. The input port configuration block uses mechanical diversion switches and interruption switches that can be controlled by a configuration block controller to dynamically change the receiver configuration from N=1 to N=4, allowing the system to adapt between different operational modes based on signal requirements
Solution Approach 2:
The receiver is divided into modular connection modules (two-way connection modules and four-way connection modules) that can be independently configured. Each module contains specific switching elements that can be controlled separately, allowing granular reconfiguration of signal paths. This segmentation enables flexible combination of multiple RF antennas and parallel channels while maintaining manageable system complexity
2Reliability
If multiple RF antennas and parallel channels are used, then the dynamic range and signal processing capability are improved, but the complexity of signal distribution and configuration increases
Solution Approach 1:
The input port configuration block serves as an intermediary device between RF antennas and parallel channels, providing centralized control over signal distribution. The configuration block controller acts as a mediator that coordinates the state of multiple mechanical switches across different connection modules, simplifying the configuration process and ensuring reliable signal routing without requiring complex manual setup
Solution Approach 2:
The connection modules are designed with universal functionality to handle multiple configuration modes (N=1, N=2, N=3, N=4) using the same hardware structure. The two-way and four-way connection modules can be selectively activated based on the desired configuration, allowing the system to universally support different numbers of antennas and channels without requiring separate dedicated circuits for each mode

AI summary
A multi-input receiver including a plurality of RF antennas, a multi-channel receiver, an input port configuration block (IPCB), and a configuration block controller. The IPCB includes at least two two-way connection modules, at least one four-way connection module, at least one direct connection module, and a plurality of electronic signal pathways. Each connection module includes a connection module input port communicatively coupled to an RF antenna of the plurality of RF antennas, a connection module output port communicatively coupled to a channel of the multi-channel receiver, and a mechanical diversion switch. The mechanical diversion switches and the plurality of electronic signal pathways are positioned and configured such that the mechanical diversion switch of each connection module communicatively couples a splitter bypass signal, a 1×2 signal, or a 1×4 signal to the connection module output port on a selective basis.
