Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing audio rendering systems in distributed networks require manual configuration for routing audio signals, which can be complex and costly, especially when dealing with multiple devices and changing network configurations.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual configuration is used for routing audio signals in distributed sound systems, then routing control is precise, but device complexity and user operation burden increase
Solution Approach 1:
The master device automatically detects the number of audio signals and performs routing configuration without user intervention. The system self-adjusts the routing mode (duplicated or different signals) based on the detected signal count, eliminating manual configuration steps while maintaining precise routing control.
Solution Approach 2:
The system changes the routing parameter (duplicated vs. different signals) based on the detected number of audio signals. When one signal is detected, duplicated routing is used; when multiple signals are detected, different signal routing is applied. This dynamic parameter adjustment simplifies operation while maintaining routing precision.
2Adaptability or versatility
If audio signals are routed to multiple wireless channels, then audio distribution capability is improved, but signal duplication and interference may occur
Solution Approach 1:
The master device dynamically adjusts the routing strategy based on the detected number of audio signals. It switches between duplicated signal mode (for single input) and different signal mode (for multiple inputs), optimizing audio distribution while preventing interference by adapting to current system conditions.
Solution Approach 2:
The master device detects the number of audio signals and uses this feedback information to determine the appropriate routing mode. This closed-loop control ensures that audio signals are distributed efficiently across wireless channels while avoiding duplication interference by selecting the correct routing strategy based on real-time signal conditions.
3Extent of automation
If automatic routing detection is implemented, then user intervention is reduced, but processing complexity in the master device increases
Solution Approach 1:
The master device performs automatic detection of audio signal count and self-configures the routing mode without user intervention. This automation reduces user burden while the processing complexity is managed through straightforward detection and decision logic that switches between two routing modes based on signal count.
