Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth remote controllers are used for Karaoke operations, then user experience is improved, but Android TV platform compatibility is worsened
Solution Approach 1:
The patent introduces a Bluetooth audio gateway as an intermediary device that bridges the gap between Bluetooth microphones/remote controllers and the Android TV platform. The gateway handles the Bluetooth communication protocol specifically, allowing Karaoke applications on Android TV to access and process audio signals from Bluetooth devices without requiring direct platform support for these protocols.
Solution Approach 2:
The system segments the audio processing functionality by separating the Bluetooth communication handling (performed by the external gateway) from the Karaoke application processing (performed by the Android TV device). This allows the Android TV to focus on executing Karaoke operations while relying on the gateway for Bluetooth protocol-specific tasks.
2Adaptability or versatility
If multiple communication standards are supported for audio input devices, then device versatility is improved, but system complexity is worsened
Solution Approach 1:
The audio gateway is designed with universal functionality to handle multiple communication standards including Bluetooth and USB audio protocols. By implementing a unified audio processing architecture in the gateway, the system can accommodate various input device types through a single multi-functional component rather than requiring separate specialized handlers for each protocol.
