Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless microphone receivers connected to coaxial antenna distribution systems often experience poor or inoperable performance due to frequency band mismatches and incorrect connections, which can lead to system instability and operational failures.
Innovation Solution
A RF distribution system that determines and verifies its configuration by modulating signals across ports, using processor instructions and device identifiers to ensure all components are connected and operating on the same band, and automatically configures receivers to optimal frequencies for compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual configuration of RF components is used, then system setup time is reduced, but connection errors and frequency mismatches occur leading to poor system performance
Solution Approach 1:
The RF distribution system performs self-configuration by automatically detecting connections between components and determining their operational status. The system instructs RF components to provide generated signals, detects these signals to verify connections, and automatically configures frequency bands without requiring manual intervention, thereby eliminating configuration errors while maintaining ease of operation.
2Measurement precision
If automatic signal detection is implemented, then connection verification is improved, but system complexity increases
Solution Approach 1:
The patent combines multiple functions into the existing RF components: signal generation, signal modulation, signal detection, and configuration determination are integrated within the RF distribution system architecture. By merging these functions into unified processing steps rather than separate dedicated modules, the system achieves accurate connection detection without proportionally increasing system complexity.
3Reliability
If frequency band matching is enforced, then operational consistency is improved, but system adaptability decreases
Solution Approach 1:
The system dynamically determines frequency band configurations based on actual connection detection results rather than enforcing static pre-configured bands. The processor instructs RF components to provide signals and detects which components are actually connected, then automatically configures appropriate frequency bands for each connected pair. This dynamic adaptation ensures operational consistency for connected components while maintaining flexibility to adapt to various connection topologies and component combinations.

AI summary
A RF distribution system determines its configuration and verifies the consistency of the determined configuration. Based on a device identifier, the RF distribution system may individually instruct each RF component to provide a generated signal. Consequently, a first RF component may modulate a signal on a first port. If a second RF component detects a modulated signal on a second port, then the RF distribution system deems that the two RF components are connected together. The procedure may be repeated for the remaining RF components so that the RF configuration of the RF distribution system may be determined. The determined RF configuration may be further verified for operational consistency. The RF distribution system may also scan a RF spectrum, determine a set of frequencies that provides RF compatibility with the RF distribution system based on the scanning, and configure the RF components in accordance with the set of frequencies.
